The Pre Pleat Series of Pleated Air filters

Pre Pleat Class 1 air filters are designed for applications where a UL Class 1 fire rated filter is required and metal frames are unsuitable.

Pre Pleat HT air filters are designed for applications where the temperatures reach up to 400ºF.

62R high efficiency pleated air filters contain an electrostatically charged filtration media which has a higher dust holding capac- ity.

 

Pre Pleat HV air filters are

 

designed to operate in

 

high velocity and turbulent

 

air applications where

 

standard pleated filters

 

tend to fail.
