Description
The Allegro 9350‑04 Deluxe Source Pre‑Filter is a rugged particulate filtration assembly designed to improve inlet air quality where ambient air contains high levels of contamination, moisture, or debris. Installed before an air filtration panel, it captures liquids and particulates as small as 5 microns, helping to reduce maintenance and replacement costs for disposable filters and improve overall performance of breathing air purification systems.
Built for demanding industrial environments, it can be used as a free‑standing unit or wall‑mounted assembly and features durable construction with a powder‑coated steel stand and quick‑connect fittings. This pre‑filter is compatible with Allegro air filtration systems and is ideal for applications in construction, manufacturing, utilities, and other settings with low ambient air quality.
