When it comes to keeping a commercial kitchen safe, clean, and compliant, exhaust system maintenance is non-negotiable. Yet, one of the simplest and most important components often gets overlooked: the grease filter. These metal filters trap airborne grease before it can travel into ducts and fans, but over time, they clog up—reducing airflow and dramatically increasing fire risk. That’s why Flue Steam offers professional grease filter exchange service to help kitchens stay safe, efficient, and compliant with fire code standards.

Why Grease Filters Matter

Grease filters are your kitchen’s first line of defense against fire. Every time food is cooked, grease vapors rise into the exhaust hood. The filters catch these particles before they enter the ductwork—where they can accumulate and ignite. When filters are clogged or saturated:

• Airflow becomes restricted, forcing exhaust fans to work harder.
• Grease begins to bypass the filter, coating ducts and fans.
• Fire risk skyrockets, as trapped grease acts like fuel.

A clean filter not only reduces hazards but also supports proper air balance and cooling in your kitchen.

The Risks of Neglecting Filter Maintenance

Failing to replace or clean grease filters regularly can lead to major problems beyond safety concerns:

• Increased Fire Risk: Grease-saturated filters can ignite under extreme heat or open flame.
• Poor Air Quality: Dirty filters reduce ventilation, causing lingering smoke and odors.
• Equipment Damage: Overworked exhaust fans and motors can overheat and fail.
• Code Violations: Health and fire inspectors frequently cite neglected filters as violations under NFPA 96.
• Higher Operating Costs: Reduced airflow forces HVAC systems to work harder, consuming more energy.

For a busy restaurant, these risks can add up quickly—not just in repair costs, but in lost business if a fire or inspection issue shuts you down.

How Professional Filter Exchange Works

At Flue Steam, we make grease filter maintenance effortless through our reliable exchange program. Our technicians visit your kitchen on a regular schedule—weekly, biweekly, or monthly, depending on your cooking volume—and replace every used filter with a freshly cleaned and inspected one.

During each service, we:

• Remove and collect used grease filters.
• Install clean, code-compliant replacements.
• Inspect hoods and airflow for potential blockages or imbalance.
• Properly dispose of grease waste in compliance with environmental regulations.

This consistent rotation ensures your system is always running at peak performance without the hassle of in-house cleaning.

Benefits of Regular Filter Exchange

Partnering with Flue Steam for ongoing grease filter service offers major advantages:

• Improved Safety: Clean filters reduce the likelihood of grease fires.
• Consistent Airflow: Balanced ventilation creates a cooler, more comfortable kitchen.
• Lower Maintenance Costs: Prevents buildup that leads to duct and fan damage.
• Energy Efficiency: Systems run more smoothly, using less power.
• Code Compliance: Meets NFPA 96 and local fire safety inspection requirements.

Plus, because we handle the cleaning and replacements off-site, your staff can stay focused on what matters most—serving customers safely and efficiently.

When to Schedule Service

Most commercial kitchens should exchange grease filters at least once per month, but high-volume or fryer-heavy operations may need weekly service. If you notice any of the following signs, it’s time for a replacement:

• Smoke or heat accumulating near the cooking area
• Visible grease dripping from hoods or vents
• Loud or straining exhaust fans
• An increase in kitchen temperature despite proper ventilation

If any of these sound familiar, your filters are likely overdue for attention.

In a busy commercial kitchen, fire is an ever-present risk. Between high heat, open flames, and grease-laden air, it only takes a moment for a small flare-up to become a full-scale emergency. That’s why a reliable fire suppression system isn’t just recommended—it’s required. But having a system in place is only half the battle. Regular maintenance and service from Flue Steam ensures your system will work when you need it most, protecting your staff, your customers, and your livelihood.

Why Fire Suppression Systems Are Essential

While sprinklers are standard in many buildings, they aren’t designed to address grease fires. Commercial kitchen fire suppression systems target the unique risks of cooking environments by:

• Detecting Heat and Flames Quickly: Activation happens within seconds, stopping a fire before it spreads.
• Using Specialized Agents: These systems release chemicals designed to smother grease fires that water would only make worse.
• Automatically Shutting Off Equipment: Many systems are connected to gas and electricity lines, cutting power to appliances during activation.

Without a suppression system, a kitchen fire can spread to ducts, fans, and the entire building in minutes.

Compliance and Legal Requirements

Fire codes, including NFPA 96, require commercial kitchens to have functional fire suppression systems. Regular inspections and maintenance are also mandatory. Neglecting this can lead to failed inspections, costly fines, or worse—liability if a fire occurs. With Flue Steam, you not only stay compliant but also gain documentation for health and fire officials that proves your system is up to code.

What Professional Service Includes

When you schedule fire suppression system service with Flue Steam, our technicians provide:

• Thorough Inspection: Checking detection devices, nozzles, and agent tanks for proper function.
• System Testing: Ensuring automatic activation and manual pull stations work correctly.
• Appliance Coverage Check: Verifying nozzles are positioned correctly over stoves, fryers, and grills.
• Recharge and Replacement: Refilling suppression agent tanks and replacing parts as needed.
• Documentation: Providing detailed service records for compliance verification.

This proactive approach ensures your system will be ready in the event of an emergency.

The Hidden Cost of Neglect

Skipping fire suppression maintenance doesn’t just risk safety—it can also lead to:

• Insurance Issues: Providers may deny claims if systems weren’t serviced properly.
• Business Interruption: A fire can shut down your kitchen for weeks or even months.
• Equipment Damage: Without automatic shutoff, appliances may be destroyed in a fire.
• Reputation Loss: Customers may not return after a fire-related closure.

For restaurant owners and foodservice operators, the cost of neglect far outweighs the investment in regular service.

Schedule Service Before You Need It

Fire suppression systems are designed to be your last line of defense—but only if they work when it matters. Don’t wait until it’s too late. Call Flue Steam at 800-700-FLUE today to schedule your fire suppression system service and keep your kitchen compliant, safe, and prepared for anything.

In a commercial kitchen, safety isn’t optional—it’s essential. While exhaust cleaning, fan maintenance, and fire suppression systems all play critical roles, there’s one tool every kitchen must have within arm’s reach: portable fire extinguishers. These compact devices are your first line of defense when a fire breaks out, giving staff the ability to act quickly before flames spread.

But extinguishers only work when they’re properly chosen, placed, and maintained. At Flue Steam, we provide fire extinguisher sales and service to ensure your kitchen is prepared for anything.

Why Fire Extinguishers Are Critical in Kitchens

Commercial kitchens face unique fire hazards, from grease splatters to overheated equipment. Fire extinguishers provide:

• Immediate Response: Staff can stop small fires before they grow out of control.
• Targeted Suppression: Different types of extinguishers are designed for grease, electrical, or combustible fires.
• Added Protection: Even with automatic fire suppression systems, an extinguisher is often the first tool reached in an emergency.
• Compliance: Fire codes and insurance requirements mandate that kitchens have extinguishers readily accessible.

Without the right extinguisher—or without one that works—your staff could be left powerless in a critical moment.

Types of Fire Extinguishers for Kitchens

Not every extinguisher is the same. In fact, using the wrong one can make a fire worse. Commercial kitchens typically require:

• Class K Extinguishers: Specifically designed for grease and cooking oil fires, these are essential near fryers and grills.
• Class ABC Extinguishers: Versatile options that handle paper, wood, electrical, and trash fires, often placed in surrounding areas.

At Flue Steam, we help you select the correct extinguishers for each zone in your kitchen and ensure they meet local fire code standards.

The Importance of Regular Service

An extinguisher that doesn’t work is just dead weight on the wall. Regular service ensures:

• Readiness: Pressure levels are checked so extinguishers will discharge when needed.
• Compliance: Inspection tags and service records meet fire code and insurance requirements.
• Safety: Damaged or expired extinguishers are replaced before they fail in an emergency.
• Staff Confidence: Knowing extinguishers are functional gives your team peace of mind.

Our technicians at Flue Steam provide scheduled inspections, recharging, and replacements so your extinguishers are always reliable.

Training Staff to Use Extinguishers

Even the best equipment is useless without proper training. Every kitchen employee should know the PASS method:

• Pull the pin.
• Aim at the base of the fire.
• Squeeze the handle.
• Sweep side to side.

Regular fire safety drills ensure staff are confident in using extinguishers quickly and effectively.

In an era of high-pressure steam systems and automated cleaning tools, it’s easy to assume that traditional methods like hand scraping are outdated. But in the world of commercial kitchen exhaust system maintenance, hand scraping is far from obsolete—it’s essential. At Flue Steam, we continue to rely on this tried-and-true technique because it offers unmatched precision, safety, and compliance.

What Is Hand Scraping?

Hand scraping involves using metal scrapers, brushes, and other manual tools to physically remove built-up grease from the interior surfaces of kitchen exhaust hoods, ducts, and fans. While it may sound simple, the process requires trained technicians who understand how to work safely in confined spaces and identify grease buildup in hard-to-reach areas.

Why Hand Scraping Is Still Critical

Even as modern technology advances, there are several reasons hand scraping remains a core part of a comprehensive exhaust cleaning strategy:

1. It’s Often the First Line of Defense

Hand scraping is the most direct and effective way to remove thick, caked-on grease before steam cleaning begins. If grease is allowed to build up over time, steam alone may not be sufficient to break it down. Manual removal ensures that the system is cleaned to bare metal standards, as required by NFPA 96 fire code.

2. It Reaches the Trouble Spots

Automated or high-pressure tools can miss narrow corners, seams, and irregular surfaces within exhaust systems. Hand scraping allows technicians to get into those spaces—especially in older systems that weren’t built with modern access panels. This detailed work can be the difference between a safe kitchen and a fire hazard.

3. It Reduces Fire Risk

Grease is fuel for fire. The more completely it’s removed, the safer your kitchen will be. Manual scraping is especially effective at eliminating highly flammable, semi-solid grease deposits that collect near heat sources and fan blades—areas where fires often start.

4. It’s Code-Compliant

According to NFPA 96 and most local fire safety codes, grease must be removed from the entire exhaust system, not just the visible parts. Hand scraping ensures compliance by making it possible to clean components that automated systems can’t reach, helping your business pass inspections and avoid costly violations.

5. It’s Part of a Holistic Approach

At Flue Steam, hand scraping is never a standalone service. It’s integrated into our complete exhaust system cleaning protocols, which may also include steam cleaning, filter replacement, fan maintenance, and more. Hand scraping plays a foundational role in this layered approach.

When Is Hand Scraping Most Needed?

While hand scraping is often used during every routine cleaning, it’s especially important when:

• A system hasn’t been cleaned on schedule
• There’s visible grease dripping from hoods or ducts
• Cooking equipment is used for high-volume frying or grilling
• A kitchen has recently failed a safety inspection
• There are signs of reduced airflow or fan strain

If any of these apply to your kitchen, hand scraping may be necessary to get things back to code.

Your commercial kitchen’s exhaust fan works hard behind the scenes—pulling smoke, heat, grease-laden air, and odors up and out of your space. But like any mechanical system, it needs regular maintenance to keep performing safely and effectively. At Flue Steam, we know that a failing exhaust fan doesn’t just slow down ventilation—it can become a major fire hazard, a compliance issue, and a threat to your entire operation.

If it’s been a while since your last fan check, here’s what professional kitchen exhaust fan service includes and why it’s essential for fire safety, ventilation, and performance.

Why Exhaust Fans Need Regular Maintenance

Exhaust fans are critical components of any commercial kitchen ventilation system. When properly maintained, they:

• Remove hot, greasy air from the kitchen
• Balance air pressure with make-up systems like swamp coolers
• Reduce smoke and odors
• Minimize grease accumulation in hoods and ductwork
• Protect against fire by venting hazardous vapors

When neglected, however, they can:

• Overheat or fail due to clogged blades and motors
• Reduce airflow, allowing heat and contaminants to build up
• Spread grease deposits through ducts, increasing fire risk
• Trip circuit breakers or cause electrical problems
• Lead to failed inspections or code violations

What’s Included in a Professional Fan Service

At Flue Steam, our fan maintenance service is comprehensive and customized to each kitchen’s needs. Here’s what our technicians typically perform during an exhaust fan service:

1. Visual Inspection

We begin with a full inspection of the fan, including mounting hardware, wiring, and vibration levels. Loose or worn components can cause premature failure or dangerous mechanical problems.

2. Grease Removal

Grease buildup on the fan blades is not only a fire risk—it also reduces fan efficiency. We remove all grease and debris from blades, housing, and surrounding areas using safe, effective cleaning solutions.

3. Belt & Motor Check

Most exhaust fans operate using belt-driven motors. We check the condition of belts, tighten tension if needed, and replace any that show signs of wear. We also test the motor for performance, overheating, or unusual noise.

4. Lubrication

Where applicable, we lubricate bearings and moving parts to ensure smooth operation and reduce wear over time.

5. Secure and Seal

We make sure the fan is properly mounted and sealed to the ductwork to prevent vibration, leaks, or safety hazards. We also verify that the backdraft damper is functional.

6. Performance Testing

Once cleaned and serviced, we power up the system and test airflow to ensure the fan is operating at full capacity. We can also check that airflow is balanced with your make-up air system for safe, efficient operation.

7. Documentation and Compliance

You’ll receive a full report of what was serviced, cleaned, or replaced—ideal for keeping on hand for health and fire code inspections.

Signs Your Exhaust Fan Needs Service

Even if it’s running, your exhaust fan may be signaling trouble. Watch for:

• Unusual noise or vibration
• Reduced airflow or lingering smoke
• Overheating or a burnt smell
• Oil or grease dripping from the housing
• Fan motor failure or frequent circuit breaker trips

Any of these issues could mean it’s time for a professional inspection.
