Design and Construction:
The unique design and construction of the BA -TP filter justifies itsworldwide reputation as a high technology filter. It's precisely–controlled radial pleat design provides the aerodynamicconfiguration which contributes to BA -TPs low initial resistance and increased dust-holding capacity. The specially developednon-woven cotton media is bonded to 1"X1" annealed wire gridwith an effective open are of not less than 96%.
Shall be comprised of a blend of non-woven cotton plus polyesterand shall have a high dust holding capacity. BA -TP filters have anaverage dust spot efficiency of 25- 30 % with an averagearrestance (efficiency by weight) of 90-92% according to ASHRAE52-76 atmospheric testing procedure. The Variances in theefficiency (up to 5 points) are typical of filters in the medium efficiency category when tested in accordance with ASHRAE 52-76standard.
