You can quickly and easily increase the efficiency and effectiveness of your commercial kitchen ventilation system with this simple and affordable method. By treating your metal mesh filters with air filter spray , you can help capture more dust, dirt, and sub-microscopic particles. A light coating is all it takes to improve your metal mesh filter’s performance and increase its arrestance.

Air filter spray is a slightly tacky, non-oily, water-soluble liquid adhesive that is applied to the leaving side of the filter. The filter spray extends the mechanical impingement of a filter by creating a positively charged surface that electrostatically attracts and traps negatively charged particles such as allergens and mold spores that would otherwise escape.

Restaurant Exhuast Fan Maintenance & Repairs

Now that we’ve covered exhaust fan basics including cleaning and general maintenance in parts one and two of of our Complete Guide to Restaurant Exhaust Fans blog series, we’ll focus on how to deal with a few common maintenance and repair issues.

While many repairs and mechanical problems require the expertise of a professional electrician or kitchen exhaust technician, routine maintenance can be as easy as ensuring the shaft bearings are greased or replacing a worn fan belt. These types of simple adjustments can be accomplished with a basic tool kit (hammer, Allen wrenches, socket wrench set, vise grips, nuts, bolts, washers, etc.)

Here are a few common issues you can easily take care of yourself. Continue reading

In part one of this blog series we discussed the basics of restaurant exhaust fans as well as the two most commonly used upblast exhaust fans — belt drive and direct drive. Today we’ll be going over exhaust fan cleaning and general maintenance.

Restaurant Exhaust Fan Cleaning

Exhaust fans require cleaning on a regular basis in order to keep grease, dirt, and other contaminants from building up in the hood and ductwork, and a greasy exhaust fan will clog up the works in more ways than one.

Regular exhaust fan cleaning is necessary in order for your exhaust system to run efficiently and keep it in good working order. And one of the most important reasons to keep your exhaust fan clean is to reduce your risk for fire. In addition, exhaust fan cleaning is required by NFPA fire codes and may also be enforced by state and local laws. Continue reading

Air Filter MERV Ratings

What is a MERV?

Minimum Efficiency Reporting Value, or MERV, is a scale that rates the effectiveness of air filters. Created by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) in 1987, air filter MERV ratings relate to the relative effectiveness of the filters they’re assigned to.

How Do MERV Ratings Work?

Filters are rated on two different performance factors as measured by testing both the upstream and downstream airflows of a given air-cleaning appliance. The first factor evaluated is how effective a filter is in removing large (greater than 1 micron in size) particles like pollen, pet dander, and byproducts from dust mites. The other factor is efficiency in filtering out particles less than 1 micron in size, such as smoke from cooking or tobacco, household dusts, bacteria, viruses, and even benzene gas. (As a matter of perspective, the eye of a needle (depending on the type of needle, of course) is somewhere in the 500-200 micron range.)

What is the Best MERV Rating for Your Needs?

Given that some 98 percent of all indoor air particles are under one micron in size, a filter’s ability to remove these minute yet potentially harmful specks is especially important when it will be used to improve the quality of indoor air. Continue reading

Having access to the internal mechanisms of a restaurant exhaust fan is an integral part of routine maintenance, cleaning, and repair. It’s also necessary for fire safety inspectors to have safe and easy access so they can ensure everything is up to code as specified by the National Fire Protection Association. Lastly, properly opening and closing the fan lessens the likelihood that damage could inadvertently occur to the fan bowl or seals.

Here we’ve outlined the safest ways to open and close upblast exhaust fans while ensuring both the safety of your employees and the safeguarding of your company’s – or your client’s – equipment. Continue reading

Kitchen exhaust hood and duct cleaning is faster and easier when you have the right equipment. Some of the most essential tools for hood cleaners are scrapers and blades. Not only are they the quickest way to get rid of accumulated grease buildup, they also help ensure that you have direct cleaning access to the entire system.

Kitchens with solid fuel cooking appliance are actually required by NFPA 96 fire codes to scrape clean the combustion chamber to its original surface at least once per week. But no matter what kind of cooking is done, a commercial kitchen exhaust system will eventually accumulate a dangerous amount of grease. And unless it is properly scraped and cleaned, it will eventually become a fire hazard.

With all steel construction and a durable comfort grip, our 4″ Heavy Duty Scraper can tackle the toughest hood cleaning jobs. It is available in a 13″ or 18″ length, features a steel end cap, and includes one heavy duty blade. Continue reading
