air cleaner filter
-Rigid construction
-Well-built
-Low initial pressure drop
-Consistent efficiency results

Description

1. Kowa Extended Surface Paper Pre Filters incorporate a 100% synthetic media with an ASHRAE 52.1 average atmospheric efficiency of 30% to 35% and an average arrestance exceeding 90% by weight.

2. The 1" and 2" filters handle velocities of up to 500 FPM, the 4" filters up to 625 FPM.

3. The media is chemically bonded to a metal mesh on the air-exiting side, preventing fluttering, and maintaining uniformity of the pleats. The filter pack is enclosed in a heavy-duty, moisture resistant, die-cut frame that not warp, crack or distor under normal operating conditions.

4. Diagonal front and back media retainers are an integral part of the fitler frame. The media pack is bonded to every part of the frame, preventing any possibility of air bypass.

Benefits

1. It is possible for a flat filter to face load, so restricting airflow and causing unnecessary strain on equipment. Kowa Series Pre Filters accumulate the heavier, more restrictive particles at the bottom of the pleats, leaving the sides open longer for effective filtration.

2. Kowa Series Pre Filters media is engineered to provide maximum efficiency. Generally, the deeper the pleats the longer filter life between changeouts.

-Rigid construction wiht consistent media exteends the service life.

-Well built, efficient and easy-to-handle medium efficiency fitlers.

-Low initial pressure drop.

-Consistent efficiency results.

Applications

1. Paper pre-filter is suitable for filter outside air in any normal A/C systems and clean room A/C systems.

2. Kowa Series Pre Fitlers can be used without modification in side-access filter housing or built-up filter bank. They offer better efficiency than conventional permanent or disposable flat fitlers.

3. Kowa Series Pre Fitler, when used as pre-filters, substantially extend the life of more expensive high-efficiency filters. They are perfect filters for residential, commercial and industrial use.
