Donaldson P191920-016-436 Replacement Filter | 14.36″ x 11.36″ x 26″ Nano Fiber Fire Retardant Oval Cartridge – Open/Open Ends

Description

Donaldson P191920-016-436 Replacement Filter: Fire-Retardant Nano Fiber Oval Cartridge for Torit Downflo Collectors (14.36″ x 11.36″ x 26″)

In environments with sparks, embers, or combustible dust—like welding bays, fabrication shops, or chemical processing—standard filters risk ignition and downtime. Our P191920-016-436 replacement filter counters that with UL 900-certified nanofiber FR media, achieving MERV 15 efficiency (99.97% @ 0.3 microns across 180 sq ft) to trap ultrafines while self-extinguishing to prevent flash fires (NFPA 654 compliant). This open/open-end oval cartridge is a precise drop-in for Donaldson Torit Downflo systems, boosting airflow by 15–20% over cellulose and slashing OEM costs by 50%—with proven durability in 12,000+ pulse cycles.
