Commercial Air Filters
reusable filter that can replace traditional disposable filters that
must be changed monthly. Addition of Filter Foam and the Two-Stage design
make the HFA more efficient than the HEA filter. Works extremely well
as a pre-filter in a progressive arrestance filtering system.
Application: Residential, Commercial, Industrial
Uses: Heaters, Air-Conditioners, Commercial Filter
Uses 25 ppi Filter Foam for Greater Arrestance and Efficiency
Washable and Reusable

HF SERIES TWO-STAGE FOAM and ALUMINUM FILTER
is designed to replace disposable air filters commonly used in residential,
commercial and industrial HVAC applications to filter airborne particulate
from the airstream, and it can be used dry or coated with Filter Coat.
Placing filter foam behind an aluminum mesh pre-filter creates the unique
two- stage design offering greater arrestance and efficiency over the
traditional, all metal washable filter.
HF Series filter uses an aluminum frame to enclose the
media pack. The first stage of the media pack is an expanded aluminum
grid, corrugated to increase its available surface area, followed by one
or more layers of corrugated aluminum screen wire. These components are
assembled in a criss-cross fashion for strength and serve to remove large
airborne particulate. The second stage is made of 25 pores per inch (ppi)
filter foam which removes smaller airborne particulate. The entire media
pack is backed by an expanded aluminum supported grid on the air exit
side of the filter. The frame is made with mitered corners and is secured
with pop rivet(s).
FILTERS AND MERV RATINGS
Efficiency Reporting Value) are used by the HVAC (Heating, Ventilating
and Air Conditioning) industry to describe a filter's ability to remove
particulates from the air. A higher MERV rating means better filtration
and greater performance.
