Centri HHEX-80 Precleaner High Heat

Centri Precleaner 8″ High Heat . This precleaner is for Extreme Heat conditions. Recommended Fire Fighting Equipment

Cal Fire worked with DRM Diversafab, manufacturer of the “Centri™” precleaner to develop a high heat resistant precleaner and ember prescreen that would meet the engine OEM air intake requirements, meet the NFPA and Cal Fire Fix-N-Fax #42 requirement of preventing burning embers larger than 0.039 inch from reaching the air filter.

DRM Diversafab was successful in their development of a “High Heat” model precleaner and a “High Heat” model prescreen to prevent any chance of a burning ember larger than .036 inch from reaching the paper air filter to comply with NFPA. The maximum temperature tolerance of the precleaner is 1,200 degrees Fahrenheit. The grease in the bearings is only good to approximately 350 degrees Fahrenheit for short duration but bearing failure will not compromise ember protection during a burn over. The prescreen made with the Kevlar® thread (locking stitching) is 900 degrees Fahreheit. The Silicone coating (gray color) on the fabric is 500 degrees Fahrenheit and the Fiberglass base fabric is 1,000 degrees Fahreheit. Centri Precleaners is recommended in all High Heat applications for over-the-road, off highway, and industrial equipment.
