• Port sizes ranging from 1/8" to 2½" to accommodate diverse industrial applications
• Pressure ratings up to 290 psig for standard applications and 125-175 psig for specialized silencers
• Global distribution network with 100+ authorized distributors for rapid parts availability

Noise-Reduction Silencers for Air Exhaust Applications

Compressed air exhaust noise represents a significant workplace safety concern in industrial manufacturing. Uncontrolled pneumatic system noise can exceed 90 dB, creating hearing hazard zones and OSHA compliance challenges. ROSS Controls silencers solve this critical problem through advanced muffler technology that reduces noise while minimizing pressure drop and backpressure.

Standard Port Silencers

ROSS standard silencers feature porous media construction that disperses exhaust air energy, converting acoustic energy to heat. Available in 12 port sizes from 1/8" to 2½" with both male and female configurations, these silencers accommodate virtually any pneumatic system.

Each silencer is engineered with specific flow coefficients (Cv ratings) that balance noise reduction with system efficiency:

• 1/8" male silencer (Model 5500A1003): 1.2 Cv, optimal for low-flow pilot applications
• 1/4" male silencer (Model 5500A2003): 2.1 Cv, ideal for proportional control systems
• 1" male silencer (Model 5500A6003): 14.6 Cv, designed for high-flow primary applications
• 2½" female silencer (Model 5500A9002): 103.7 Cv, supports maximum flow industrial systems

Pressure ratings to 290 psig (20 bar) ensure reliable performance across standard industrial applications, from automotive assembly lines to metal forming presses.

Stainless Steel Silencers for Corrosive Environments

Manufacturing environments with corrosive atmospheres—including food processing, pharmaceutical production, and chemical processing facilities—demand corrosion-resistant materials. ROSS stainless steel silencers provide superior durability and extended service life in demanding environments.

Our stainless steel silencer line includes four standard sizes (1/4", 1/2", 1", 2") engineered for NPT thread configurations with pressure ratings to 175 psig. The compact design facilitates retrofit applications on existing systems without extensive reconfiguration.

Noise Reduction Silencers for DM1 & DM2 Series C Double Valves

High-flow applications demand specialized silencer solutions engineered specifically for double valve configurations. ROSS engineered silencer kits for DM Series C valves deliver exponential perceived noise (EPNdB) reduction of 35-40 dB across five flow capacity ranges:

• Small flow applications (800 scfm): Models 2324H77/2329H77 with dimensions 4.34" A x 19.06" B
• Large industrial applications (7,200 scfm): Models 2327H77/2331H77 with dimensions 9.85" A x 41.55" B

Complete installation kits include all required plumbing connections, eliminating procurement challenges and accelerating system deployment.

L-O-X® Air Entry Assembly Silencers

ROSS stainless steel L-O-X air entry assemblies require specialized silencer designs that maintain system integrity while providing noise reduction. Our dedicated silencer line accommodates three port sizes (1/4", 1/2", 1") with NPT and BSP thread configurations and pressure ratings to 125 psig.

These silencers feature nitrile seals compatible with standard compressed air applications while maintaining the corrosion resistance properties essential for specialty manufacturing environments.

Flow Rate Specifications & Pressure Ratings

Proper silencer selection requires understanding both the intended application and the associated flow characteristics. ROSS silencers are engineered with optimized pressure drop curves that prevent system performance degradation:

• Low Flow Applications (Cv < 5): Proportional valve pilots, control circuits, logic systems
• Medium Flow Applications (Cv 5-30): Single-valve primary exhaust, combination systems
• High Flow Applications (Cv > 30): Large double valves, high-speed press systems, production assembly lines

Pressure range specifications are critical—operating silencers beyond rated pressures accelerates seal degradation and reduces effective noise reduction. ROSS technical documentation provides detailed pressure vs. flow curves enabling precise component selection for specific applications.
