Application: The HIS SERIES INDUSTRIAL GRADE FILTER is designed for use
in residential, commercial and industrial HVAC applications to remove
airborne particulate and coolant mist from the airstream. It can be used
dry or coated with Filter Coat and is built to withstand repeated cleanings.
There are 2 alloys of stainless steel most commonly used in the air filtration industry, 304 stainless steel and 430 stainless steel. Both alloys are highly corrosion resistant but 304 stainless steel has an added alloy, nickel, which makes it even more corrosion resistant than the 430 stainless steel. It does add to the cost of the filter, but if durability is considered, it is well worth it. Also, 304 stainless steel is non-magnetic while 430 is magnetic. However, if appearance is considered, 430 stainless steel is shinier and looks better where aesthetics are important. 304 stainless steel has a maximum operating temperature of 900 degrees F while 430 stainless steel has a maximum operating temperature of 700 degrees F.
Construction: The HIS Series uses a 304 stainless steel frame to enclose the media pack
which consists of multiple layers of corrugated 304 stainless steel screen wire assembled in
a criss-cross fashion for strength. The pack is then placed between two
layers of expanded 304 stainless steel and is made to fit firmly inside the frame giving
the HIS Series filter its exceptional strength and durability. The frame is
made with mitered corners and is secured with pop-rivet(s).
