Hot Gas & Steam Air Filter Housing

Overview

This industrial stainless-steel filter housing delivers high-performance air, gas, and steam filtration using a durable SUS304L/316L, 2 mm reinforced body with a mirror-polished interior. It supports DOE, 222, and 226 filter elements, operates across a wide 0.1–200 μm micron range, and achieves 99.9% impurity removal. Rated for 100–300 psi and up to 150°C, it’s built for demanding environments including sterile air supply, steam filtration, and high-temperature gas processes.

Compatible with nitrogen, oxygen, CO₂, hydrogen, helium, methane, propane, steam, and more, this housing integrates easily with standard flange connections and multi-stage filtration setups. Each unit includes a differential pressure gauge, safety valve, drain valve, silicone seals, QA test report, and inspection video—backed by ISO-certified manufacturing and a 1-year warranty for long-lasting, reliable performance.
