PLEATED AIR FILTERS

General
Precisionaire Pre Pleat 40 extended surface pleated filters are designed to operate in most every type of installation. Available in 1 in., 2 in., and 4 in. nominal thickness, these filters have an average atmospheric dust spot efficiency range of 25-30% per ASHRAE Standard 52.1 test methods. Pre Pleat 40 filters offer greater efficiency and service life than disposable filters, pad and frame systems, or metal washable filters. The overall design of this product makes these filters the accepted choice in applications requiring high performance and extended service. These filters are suitable for variable air volume systems. Operating face velocity ranges are from 0 to 500 fpm for 1 in. and 2 in. filters, and from 0 to 625 fpm for 4 in. filters. Economy, Standard and High Capacity designs are offered. (Capacity is increased by the addition of pleats/media.) Pre Pleat 40 filters are UL 900 Class 2 listed but are available with UL Class 1 listing.

Versatility
Most heating, air conditioning, or ventilating systems can be upgraded with the use of Pre Pleat 40 filters in place of existing flat panel types. The inherent strength of the filter allows for easy changeout as it will not collapse, warp, or bend in normal service. Pre Pleat 40 filters are available in a wide range of sizes and will fit most commercial and industrial installations with little or no system modification. Fasteners are available to adapt the filter to existing filter banks.

Principles of Operation
Precisionaire’s v-pleat design insures that the greatest media area is exposed to the air flow to promote uniform dust loading. Competitive filters cannot maintain this rigid shape and tend to flatten out, using only a portion of the media. This v-pleat design creates an air exit area (B) equal to the air entering area (A), which minimizes end losses and reduces pressure drop. Radial wedge pleats have unequal air exit (D) and air entering (C) areas, which cause higher resistance and uneven use of media.

Media for efficiency Air Cleaners

Models 500AB, 600SG and replacement cartridges for selected Honeywell® air cleaners are made with a blend of polypropylene and polyethylene electrostatic filtration media which is adhered to an expanded metal backing. This combination is deep pleated and encased in a moisture resistant kraft board frame and offers a MERV 8 rating.

Models 550AB and 650SG cartridges are similar to our industrial grade PrecisionCell II air filter, with perfectly spaced mini-pleats of wet laid glass microfiber media and a moisture resistant kraft board frame. This provides high efficiency filtration and a longer filter life and a MERV 10 rating.

Model 650SG media inserts consist of the same media as the 550AB and 650SG cartridges but are provided in a convenient, easy to store package. They are pleated to the proper depth with fastener strips secured to each outside pleat.
