Learn about the two important functions of clean grease filters in the commercial kitchen.

In the world of commercial kitchen exhaust system cleaning, a lot of attention is given to keeping exhaust hoods and ductwork clean. But grease filters are actually another very important piece of the puzzle.

Grease filters perform two very important functions in the commercial kitchen:

Fire Prevention: The first function of a clean grease filter is to help reduce fire hazards in the commercial kitchen. As grease-laden air passes through the filter, the grease particles are captured. The end result is less grease getting into the ducts, where it could pose a serious fire hazard. Some types of grease filters also include a spark arrestor feature, which provides even more fire protection by preventing sparks generated by cooking with solid fuels like wood or charcoal from entering the ductwork.

Proper Airflow: The second function of a clean grease filter is to help promote proper airflow in your kitchen. Without a grease filter, the extra grease that would accumulate on the walls of your ductwork could actually increase drag inside the ducts. This would cause your exhaust fan to work overtime, potentially increasing wear and tear on the system. The reduced airflow would also lead to issues with smoke and odors in the kitchen.

Unfortunately, the dirtier a grease filter gets the worse it performs. A dirty grease filter can be a fire hazard in and of itself, and it can also restrict airflow even more severely than dirty ducts would.

How to Keep Your Grease Filters Clean

Grease filters for commercial kitchens may get dirty quickly, but the good news is they are designed to be cleaned and reused. As a first step, you should have your staff inspect the grease filters at the end of each day. If the filters appear greasy, they should be removed and cleaned. Most types of grease filters can be cleaned easily by applying a degreaser, letting them sit a while, and then running them through your commercial dishwasher.

But what if your staff doesn’t have time for these tasks? Or what if your kitchen runs 24 hours and you can never leave your appliances without grease filters for any amount of time? You can use Flue Steam’s grease filter exchange service to guarantee yourself clean filters.

We will come out every week or so to remove your old, dirty filters and replace them with clean ones. This doesn’t mean you have to purchase new filters every time—instead we will clean your old filters for you and bring them back on the next visit. So you really only need two sets of filters to take advantage of this service.

Flue Steam provides expert exhaust fan cleaning and inspections.

In any commercial kitchen, a properly designed exhaust system is essential for drawing hot, smelly, greasy air out of the kitchen. This prevents kitchen workers from becoming uncomfortable and also helps keep kitchen smells from overpowering the dining area. Plus, by removing greasy air it reduces your risk of fire. The powerhouse behind your exhaust system is of course the exhaust fan. It is obviously very important to get care and maintenance for your exhaust fan! As your kitchen air control expert, Flue Steam is the perfect company to care for your exhaust fan. Here are our suggestions for the best possible care.

Get Frequent Cleanings

While the portions of the exhaust system nearest your cooking surfaces (such as exhaust hoods) accumulate grease the fastest and need the most frequent cleanings, duct walls and fan blades will also accumulate grease over time and also need regular cleanings. At Flue Steam, we can help you determine the proper frequency for your exhaust fan cleanings.

Install a Hinge Kit

If you have a rooftop fan, installing a hinge kit will help make it easier to clean the fan. The hinge kit allows the entire fan mechanism to be tilted back off of the duct opening so that the fan cleaning can be tackled from multiple angles. It also helps ensure that the fan is replaced correctly after each cleaning.

Limit Grease Buildup

Just because you know you have scheduled frequent exhaust fan cleanings doesn’t mean you shouldn’t also take steps to limit grease buildup on the fan between cleanings. After all, grease buildup can increase wear and tear on your exhaust fan in two ways. First, grease adhering to the mechanism of the fan itself can cause wear and tear on the system. Secondly, grease adhering to the duct walls can also stress the fan, because the fan has to work harder to draw air past the increased resistance presented by greasy duct walls. To help prevent grease buildup from making your fan fail faster, you should consider installing quality grease filters. This will help reduce the amount of grease that gets in the ducts in the first place. Try our grease filter exchange service for a convenient and reliable source of clean filters.

Have Your Exhaust Fan Inspected Regularly

One final way Flue Steam can help you care for your fan is by providing a free exhaust fan inspection on every cleaning visit. We will grease the fan bearings and check the belts and other vital parts. If we see a worn belt that needs replacing and you have a new belt on hand, we will put in the new belt at no extra charge.

Overcome the obstacles that are preventing your business from getting thorough cleaning with help from Flue Steam.

Keeping your kitchen exhaust system clean isn’t just the law—it also provides many important benefits for your business. Unfortunately, some commercial kitchens don’t get the thorough cleaning they actually need. There may be many different reasons for this, but here are 4 common possibilities.

Not Ordering Service

First of all, some commercial kitchen owners or operators may simply fail to order the thorough cleaning service needed to remove grease from every inch of the exhaust system. This is more likely to happen in kitchens that don’t cook a large volume of greasy food. Grease then builds up very slowly on visible areas of the exhaust system such as the exhaust hoods, and owners may assume it is building up even slower further inside the system. Because they can’t see this buildup, they may not realize that a problem is indeed growing.

Using the Wrong Company

Another very common problem is using the wrong exhaust system cleaning company. Many companies are content to just clean the visible parts of the system. They may reach up into the plenum and ducts as well, but they won’t go further than their arms and equipment can reach. Relying on a company that promises your ducts are “clean” without actually providing complete steam cleaning of the entire system is naturally a huge impediment to keeping your ducts grease-free.

Lack of Access Points

A lack of sufficient access to the ductwork is another serious obstacle to proper cleaning. NFPA codes require that approved access doors be installed in the system at specific intervals. Depending on the design of the ductwork this may mean you need a door that a person can enter through or smaller access panels at pre-set intervals. You should also have a hinge kit on your rooftop exhaust fan to facilitate proper cleaning of that important piece of equipment.

Budget Concerns

Sometimes, kitchen owners may hesitate to order service as frequently as they really need to out of concern about the cost. In reality, the cost of service is very small compared to the possible costs of a fire breaking out in the ductwork. Clean ducts also draw air better, contributing to lower cooling bills and lower gas bills (propane flames on cooking appliances will burn higher with better air flow). Remember, the longer you wait between duct cleanings the more grease will build up and the more difficult—and costly—it will be to remove.

At Flue Steam, we can help you overcome all of these obstacles and get the thorough cleanings your business needs. We provide extremely thorough steam cleaning services to reach every corner of your ductwork, even the parts you can’t see. We can measure grease deposits throughout the system to determine the proper frequency of hand scraping and steam cleaning to help you understand when to order service, and we can install code compliant access panels for you. And of course, our services are very cost-effective. Please call now to schedule your service at a time that is convenient for your business.

Learn how and when to remove grease from your appliances for cost-effective fire risk mitigation.

Exhaust hood and duct cleaning is an essential service for commercial kitchens because it helps reduce the risk of fire in the exhaust system. At Flue Steam, we offer two different methods for exhaust hood cleaning: hand scraping and steam cleaning. Depending on your kitchen’s needs, we may need to use these cleaning techniques at different intervals in order to best promote fire safety in your kitchen.

Every 30 Days

In kitchens that prepare a high volume of grilled meats or fried foods, the exhaust hoods on cooking appliances need to be cleaned monthly by hand scraping. Typically, the main appliances that need to be cleaned include ranges, broilers, fryer vats. Depending on the layout of the kitchen, these appliances may have a shared exhaust hood or individual ones.

Every 90 Days

In kitchens that don’t focus so heavily on grease-producing foods and cooking methods, it may be sufficient to get hand scraping for ranges, broilers, and deep fryers much less frequently, perhaps even every 90 days. In other kitchens where hand scraping is occurring every 30 days, these same appliances will most likely need steam cleaning every 90 days.

Every Year

If might surprise you to learn that the exhaust hoods over non-grease creating appliances also need to be cleaned periodically. This includes appliances like steam kettles, soup vats, and even dishwashers. This is because even with proper ventilation hoods over all cooking equipment, minute amounts of greasy vapor still have the potential to escape and adhere to other surfaces. Typically cleaning these other exhaust hoods once per year is sufficient.

Find the Right Cleaning Schedule for Your Kitchen

Of course, the 30-day and 90-day guidelines are just starting points. Your particular kitchen may need more or less frequent cleaning. As long as you keep grease buildup within the level that is considered safe and remain in compliance with your local fire safety codes, you have the freedom to stray from the general guidelines.

At Flue Steam, we can help you establish a cost-effective schedule for your exhaust hood and duct cleaning needs. We do this by using a special industry-approved comb to measure grease deposits on interior hood and duct surfaces. This helps us establish the rate at which grease is being deposited which then determines the frequency at which it needs to be removed.
