Porous Metal Filter-Muffler
Porous Metal Filter-Muffler
The ALWITCO Porous Metal Filter-Muffler is a compact, low-profile noise reduction component designed for selective permeability with optimum filtering and diffusion. It features a tough cellular porous metal element bonded securely to a heavy-duty steel ferrule, providing a high-strength design that excels in confined workspaces. This dual-action device safely vents exhausting pneumatic air blasts while separating oil mists, trapping water vapors, and catching micro-particulates. It serves as a reliable solution for maintaining stable pressure or vacuum equalization across systems.
Ardee Hi-Tech Pvt. Ltd. is the official and authorized distributor of ALWITCO products in India.
