20 x 20 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.
