The Porous Metal Series is an economical line of compact, low-profile pneumatic components engineered for extreme durability and heavy-duty noise reduction in space-constrained industrial environments. Unlike traditional fiber-based silencers, this series utilizes a rugged sintered porous bronze construction to filter air, diffuse high-pressure blasts, and suppress harmful workplace noise.
Core Technical Specifications & Engineering Benefits:
-
High-Strength Construction: Manufactured using standard 40-micron sintered porous bronze permanently bonded to zinc-plated steel housings for maximum mechanical integrity.
-
Corrosion-Resistant Upgrades: Available in All-Stainless Steel (316 SS) configurations for highly corrosive, sterile, high-temperature, or medical-grade environments.
-
Optimized Pressure Handling: Designed to reliably manage standard pneumatic systems with working pressures up to 125 PSI (8.6 Bar).
- Selective Permeability: Engineered with a uniform pore distribution that facilitates balanced filtering, fluid separation, and smooth mechanical diffusion for air, alternative gases, and industrial liquids.
Where to Use ALWITCO Porous Metal Components:
The unique engineering properties of sintered porous bronze allow this versatile series to serve multiple functions across automation and industrial machinery:
-
Pneumatic Exhaust Muffling: Ideal for installation on directional control air valves, manifolds, and pneumatic cylinders where rapid venting creates hazardous high-frequency workplace noise.
-
Pressure Equalization & Breather Vents: Extensively used as Porous Breather Vent Filter Mufflers on gearboxes, crankcases, storage tanks, and chemical vessels. They allow systems to breathe safely during temperature or volume shifts while locking out external dust and dirt.
-
Pneumatic Speed Customization: Utilized via the Porous Adjust-A-Flow Mufflers variant. Equipped with an integrated, manually adjustable metering screw, it provides needle-point precision over cylinder stroke speeds and line backpressure.
- Fluid Separation & Mist Coalescing: Deployed in systems prone to heavy oil mist or condensation bypass, capturing liquid aerosols before they vent out onto the plant floor.
