Pneumatic Exhaust Silencers & Mufflers

Product Overview

The Industrial Pneumatic Silencer Series is engineered to provide superior noise reduction and contaminant filtration for air-operated equipment. Excessive noise from pneumatic exhaust can create a hazardous work environment and damage sensitive machinery; our comprehensive range of mufflers solves this by diffusing air flow through high-porosity materials, significantly lowering decibel levels without creating excessive backpressure.

Whether you need the heavy-duty durability of 304 Stainless Steel, the precision flow regulation of a BLL Throttle Silencer, or the space-saving design of an SLM Flat-Head unit, this series offers the perfect balance of acoustic performance and airflow efficiency. Each muffler is designed with standardized threads (R, NPT, G) for instant installation into solenoid valves, air cylinders, and manifolds.

Featured Muffler Configurations

• MJ & BSL (Sintered Bronze Standard & Long):

• Crafted from high-quality sintered bronze powder, the MJ series provides a classic cone shape for optimal diffusion.

• The BSL (Long Type) features an extended surface area, offering even greater noise suppression and filtration for high-volume exhaust systems.

• 304 Stainless Steel (SS304):

• Designed for extreme environments, these silencers offer maximum resistance to corrosion, high temperatures, and chemicals. Ideal for food processing, pharmaceutical, and offshore applications.

• SLM (Flat-Head / Compact Type):

• The low-profile SLM series is perfect for tight spaces where a standard cone muffler would be too large. It provides efficient silencing in a streamlined, hexagonal design.

• BLL (Flow Control / Throttle Silencer):

• A dual-purpose component that combines an exhaust muffler with a built-in needle valve. This allows operators to adjust the cylinder speed by throttling the exhaust air while simultaneously reducing noise.

• PSU (Black Plastic / Nylon Type):

• Lightweight and chemically resistant, the PSU series offers an economical solution for general automation. Its black finish and reinforced structure make it durable and visually integrated with modern plastic manifolds.

Key Performance Benefits

• Significant Noise Reduction: Capable of reducing exhaust noise by 20–35 dB, ensuring compliance with workplace safety regulations.

• Contaminant Filtration: The porous structure acts as a secondary filter, preventing dust and debris from entering the internal components of valves when the system is at rest.

• Minimal Backpressure: Optimized pore sizes ensure that air is exhausted freely, preventing loss of actuator speed or system efficiency.

• High Pressure & Temp Resistance: Metal variants (Bronze and SS304) are rated for high-pressure bursts and wide temperature fluctuations.
