The 20 x 25 Thrift-Aire MAKE UP AIR FILTER consists of seven layers of expanded Aluminum grid, enclosed in a heavy Aluminum Frame. Designed for applications where a sturdy Aluminum filter is required.
20 x 25 THRIFT-AIRE FILTER
Six layers of expanded Aluminum, surrounded by a medium weight Aluminum frame make up the Thrift-Aire Filter. Designed for air applications such as, light industrial, commercial, schools, office buildings and homes where a medium weight permanent filter is recommended.
These unique filtering elements are designed for maximum retention of dust and foreign particles in the air. Six layers of media account for a high retention efficiency and less clogging of the filter itself. Because of the design, the filter has a greater load capacity with a low air resistance. The THRIFT-AIRE is UL Approved for Air and has surpassed the Federal Specification ASTM F872 required by all government contracts.
CONSTRUCTION – Filtering element is processed from sheet Aluminum, commercially known as 3003-H14, no less than .025 in thickness expanded through no less than .020 feed. The material is expanded in a special pattern of various densities. The filtering element shall consist of not less than six layers of material, and assembled so that each layer shall be at right angles with the proceeding layer. Each filtering element shall be corrugated from 1/4″ to 3/8″ to provide maximum dust holding capacity.
The THRIFT-AIRE Filter shall be framed in a formed aluminum channel, not less than .025 thickness. Corners are mitered and secured at one corner by heavy rivets. Holes shall be punched on one side of the frame to facilitate drainage after cleaning. Handles available upon request at an additional charge.
The THRIFT-AIRE Filter shall retain 290 grams of dust per 2.25 square ft (20×20 filter). Maximum resistance at capacity is 0.335 wg at 350 FPM air velocity. The THRIFT-AIRE has the same patented media design as the heavier, more costly filters, yet is less expensive. The light weight contruction makes removal and cleaning quick and easy. This permanent filter is constructed exclusively from Aluminum, giving it a resistance to rust and corrosion, giving the THRIFT-AIRE filter, a long life expectancy.
The THRIFT-AIRE Filter is a lightweight Aluminum filter, designed to be used in many forced air applications. Some of these include air handling units in office buildings, homes, schools, as well as light industrial. These filter can be used as a mist eliminator as well as a filter in a light duty grease application.
STOCK SIZES – There are a wide variety of stock sizes to choose from with the THRIFT-AIRE Filter. As with all permanent filters, the stock sizes are actually 1/2″ under the specified size (for example, a 20x20x2 is actually 19 1/2 x 19 1/2 x 1 7/8).
SPECIAL SIZES – Custom sizes are manufactured to fit odd-size applications. In ordering sizes other than those shown in the price book, state exact size required in length, width and thickness. Also available, 3″ and 4″ thick filters.
Special sizes can not be returned for credit.
CLEANABILITY – Because of the lightweight Aluminum design, this filter is one of the easiest filters in its class to clean. It will not rust, pack or flake and can be cleaned many times without losing shape or efficiency. For best results, use either steam or hot water, with or without a mild detergent. Do not soak any aluminum filters in strong alkali.
For maximum filtering efficiency, use Simple Green or other NON Caustic Cleaner when cleaning.
THRIFT-AIRE FILTER IS RATED TO 240 DEGREES F.
