Permanent Filters

A complete line of washable filters with extra strong framing. These long lasting filters are offered in aluminum or galvanized steel. Whether it's for an air conditioning unit or an exhaust hood, you will find the filter you need in this selection. Also available: the Frame, in which you insert the media of your choice; and the L-Frame, which allows you to create a filtration wall.

Durability and Economy: Just What You've Been Looking For!


Alumi Flow

Alumi Flow
Made of aluminum with a galvanized frame, the Alumi Flow is an efficient permanent filter. Available with aluminum frame upon request. Used in ventilation and air conditioning systems; in hot air systems and in exhaust hoods. The Alumi Flow filter is made of aluminum foil expanded from various thicknesses into a number of different patterns. Through an exclusive manufacturing process, the layers are then bonded together to form a baffle type design.

Grease and dust gather on hundreds of surfaces with no risk of loss of pressure or obstruction. Its performance in terms of velocity ranges from 300 to 600 fpm. Magnification shows baffle pattern with average dust arrestance of 75%. Ribbed frame for more strength.


Eze Low

Eze Low
The Eze Flow filter's frame is similar to the Perma Flow's frame. The difference can be found in the internal material, which is constructed from multiple layers of woven aluminum screen overlaid at 60 degrees from each other. This unusual process lets dirt load deep into the filter's crevices rather than just on the surface, thus allowing for greater dust holding capacity, which in turn leads to longer periods between filter cleanings.

High temperature applications : the Eze Flow filter meets Class 1 specifications.

Maintenance: Dirty filters should be removed and washed in hot water. Agitate to ensure deep cleaning. A mild solvent can be mixed with water. Dry thoroughly and coat with filter adhesive.

Perma Flow

Perma Flow
Perma Flow filters are made of a permanent, washable hog-hair type media in a no. 22 gauge galvanized metal U frame, with high resistance laths on each side.


Baffle

Baffle
Designed to keep grease from depositing and building up in exhaust hoods. Unlike conventional mesh type filters, grease is collected from the air exhausted from the cooking area and runs down the vertical baffles to drainage holes, where it drops into troughs that lead to the collection can. The staggered, interlocking design of its baffle plates prevents flash flame from penetrating the plenum and ductwork.

The baffle filter is offered with optional bail or lock handles to comply with specific building or health codes requiring filters to be locked to the exhaust hood.


Electrostatic filter

Electrostatic filter
The electrostatic filter uses static electricity to create a passive (non-electric) air cleaner. Two layers of polypropylene grids create a harmless static charge that attracts and holds airborne allergenic house dust. The electrostatic filter has 0.15 initial resistance and removes laboratory test dust up to 94% arrestance.

House dust is composed of a mixture of fibers from different types of fabrics, feathers and other stuffing materials. It also contains bacteria, mold and fungus spores, pollen, food particles, human and pet dander, bits of plants and insects, hairs and those dreadful dust mites, these crab-like bugs so tiny that 42,000 live in one ounce of dust and two million can take up residence in an average bed.


L-Frames

L-Frames
Create a filtration wall with these modular filters L-Frames are available in six standard sizes: 16x20, 16x25, 20x20, 20x25, 12x24 and 24x24. Once the L-frames are assembled, filters can easily be installed. This modular system is especially useful as it allows for use of medium and high efficiency cartridges as pre-filters as well as final filters. Each frame is made of 16-gauge galvanized steel and features a self-sealing joint to prevent air bypass.
