Pre Pleat HT
High Temperature Pleated Filters
Standard Capacity: 84555.xxxxxx
High Capacity: 84655.xxxxxx
Up to 400 o F
Flanders Pre Pleat HT filters are designed for
increased air filtration efficiencies in an operating
environment where temperatures reach 400
degrees Fahrenheit Typical examples include air
intakes for drying ovens or high temperature baking
applications.
Construction
The Pre Pleat HT high temperature pleated air filter
consists of a nominal 50% dust spot efficiency
micro-fine fiberglass filtration media that has been
bonded to corrosion-resistant expanded metal
backing, then pleated into either standard or high
capacity packs.
Each pack is encased within a 24 gage corrosion-
resistant metal frame with an expanded corrosion-
resistant metal face screen on the downstream side
to increase pack rigidity while preventing blowouts.
Flanders Pre Pleat HTpleated air filters are offered
in two inch depths in all of the most popular face
sizes. They have been tested by Underwriters
Laboratories, Incorporated and found to meet the
stringent performance characteristics of a Class 1
air filter for flammability as outlined in Standard
900.
