Description
The Allegro 9350‑03 Air Source Pre‑Filter is a robust particulate filtration assembly designed for use ahead of breathing‑air filtration panels in industrial and challenging environments where inlet air quality is especially poor. By capturing liquids and contaminants as small as 5 microns, this pre‑filter helps reduce wear on disposable filter elements and improve the overall efficiency and longevity of supplied‑air respirator systems.
Constructed with a powder‑coated steel stand and quick‑connect fittings, the unit can be used as a free‑standing unit or mounted on a wall near the compressed air source. It includes an adjustable high‑pressure regulator and pressure gauge so air delivery can meet the NIOSH requirement for point‑of‑attachment systems. With a maximum rated pressure of 250 psi and a flow capacity up to ~165 CFM, the 9350‑03 supports reliable performance in construction, manufacturing, utilities and other industrial applications.
