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.
