Up to 400 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.
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 corrosionresistant metal face screen on the downstream side to increase pack rigidity while preventing blowouts.
Flanders Pre Pleat HT pleated 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.
