The P.S.B.T. filter is made of one layer of dry polyester and one layer of tackified polyester, solidly glued together on a wire frame. These filters are available in standard and non-standard sizes.

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.

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.

Disposable filters are made of progressive density synthetic microfibres in sturdy cardboard frames. Media and frame are thermosealed to prevent air bypass. This type of filter is perfect for either residential or light commercial applications. The frame features a notch at each end in order to stack filters more efficiently in their box, saving about 33% of the space required for storage, shipping and handling.

DC 20 filters are strong and durable. Two pieces of flameproof cardboard are interlocked and sealed to prevent air bypass. Filtration is ensured by fiberglass media. On the air entry side, fibers are looser, becoming tighter as they get closer to air output, which increases dust retention capacity and retains the smallest particulate. These commercial grade filters, which can be equally used in commercial or industrial environments, help prevent dust accumulation in coils, vents and other air conditioning and ventilation system components.

DC 20 disposable filters are available in a variety of standard sizes, in 1" and 2" thickness. Non-standard sizes are also available upon request.

All DC 20 disposable filters are UL and ULC class 2 approved. Suggested maximum operating temperature: 200°F (92°C).
