Grease Baffle Filters: Stainless Steel Baffle Filters

Grease filters are designed to remove grease particles from exhaust air streams.The most common grease filters currently in use are the baffle-type. Permatron’s metal grease baffle filters are available in three models. Our metal grease filters are made of galvanized steel, aluminum or stainless steel.

How Do Metal Grease Filters Work?

Our baffle grease filters are 2″ thick and contain two layers of roll formed baffles which are equally spaced. The spacing built into the filter creates an optimized air flow which helps collect the grease inside the filter. Grease then drains down the baffles and into collecting a trough. Permatron metal grease filters are designed to prevent flames from passing through the filter baffles. They are constructed from different materials to withstand different temperature levels.

Constructed from different materials to withstand different temperature levels, Permatron metal baffle filters are available in:

Model GFG constructed of galvanized steel for a maximum temperature 450 degrees F; Classified by UL (grease) NFPA std. 96.
Model GFA constructed of aluminum for a maximum temperature 250 degrees F.
Model GFS constructed of 304 stainless steel for a maximum temperature of 900 degrees F; also available in 430 stainless steel.

Testimonials

The distributor you got me in contact with sent me the three PreVent Model R filters I was looking for. They are working great. Thank You.
Robert M. CoutureSeaman Paper Company of Massachusetts, 3rd Class Steam Engineer
Everything was correct & professionally served, finely crafted with accurate dimensions of quality material. I will purchase further metal mesh filters from your firm in the future as demand calls for.
Steven Sutherland HVAC Contractor, South Carolina
We had to change a combined condensing / free cooling coil because it was so badly damaged from debris and washing. 10k€ (approx. $12,000 USD) for the coil and works and 6k€ (approx. $7000 USD) for the crane hire. The second chiller on the site is perfect as the screen was fitted back some time ago.
Dave ClarkeCORE AIR CONDITIONING, SERVICE MANAGER
The filters we purchased are a great addition to our plant operations. I am looking at other applications for their use…
Ben StevensValero Renewable Fuels, Maintenance Manager
The order process went very well. We received the black washable fan bonnets 2 weeks ago and are very happy. I will order again in the future. Great product and great service. Thank You!

It’s always a great idea to protect HVAC condenser coils with screening, especially if you can do it right after new equipment installation. Once the magnets where inserted into the screen grommets, it took literally less than a minute to place the screening on the equipment, adjust it, done. This screening will protect the condenser coils from grass cutting, bugs, cottonwood seedlings, etc.

The guys love them! Clean look, and easy to clean….

Our customer, Logoplaste, uses and raves about the Prevent BHA Screens and MagnaMount Kits.We did an install at their manufacturing facility in June on two units, all four sides required screens. Installation time was drastically reduced from the original 6 hour estimate with standard mount clips, to complete screen installation in under 1 hour with MagnaMount clips.The facility is located along the river where cottonwood trees are very abundant. Even when installing PreVent, it was catching the cottonwood that was flying. I brought him out one of your cleaning brooms a week after install, and the Maintenance Manager said that it is the best money he has spent since he has worked at that facility. He is planning on purchasing some more for his 4 Cooling Towers as well.

The PreVent bonnet style filter is the best thing I have ever bought to protect our cooling tower circular fan. We have to clean it every two weeks but it is so easy.
Martyn RogersCotek Papers Limited, Maintenance Manager
Permatron's PreVent screening was installed on recently replaced 363A RTU condenser coils, outside air and economizer openings, using MagnaMount magnets to hold them in place VS drilling and screwing them on. The magnets will most definitely be our primary mounting option going forward. All three screens took us literally less than five minutes to install. I noticed how quickly cottonwood was caught by the screening.The screens can be cleaned in place or easy removed for more detailed cleaning.
