Prevost Exhaust Mufflers

Description

Prevost Exhaust Muffler

Superior Noise Reduction for Pneumatic Exhaust Ports

The Prevost Exhaust Muffler is a vital component for any pneumatic system, designed to significantly reduce the high-decibel noise generated by air escaping from exhaust ports. When pressurized air is vented from valves, cylinders, or manifolds, it creates a sharp, turbulent blast that can be harmful to hearing and disruptive to the work environment.

Prevost mufflers solve this by diffusing the air through a porous medium, lowering the exhaust velocity and bringing noise levels down to a safe, comfortable range without causing excessive backpressure.

Key Features

• Exceptional Noise Attenuation: Engineered to meet strict workplace safety standards, these mufflers effectively dampen the high-frequency “hiss” of exhausting air, protecting operators from noise-induced hearing loss.
• High-Flow Porous Media: Available in sintered bronze or high-density plastic, the internal filtering element allows air to vent freely. This ensures that the speed and cycle time of your cylinders and actuators remain consistent.
• Compact, Low-Profile Design: The streamlined shape allows these mufflers to be installed directly into the exhaust ports of directional control valves, even in tightly packed control cabinets or manifold blocks.
• Contaminant Protection: In addition to silencing, the muffler acts as a barrier, preventing dust, dirt, and shop debris from entering the valve through the exhaust port, which extends the life of internal seals.
• Corrosion-Resistant Construction: Manufactured from high-quality materials such as nickel-plated steel, sintered bronze, or industrial polymers to withstand oily air and humid environments.

Technical Specifications

Available Styles

• Sintered Bronze Mufflers: The industry standard for durability and high-temperature resistance.¹ Features a rugged hex base for easy installation with a standard wrench.
• Plastic “Cylindrical” Silencers: Lightweight and cost-effective, these are ideal for standard automation applications where high impact resistance isn’t required.
• Adjustable Speed Control Mufflers: Features an integrated needle valve that allows you to simultaneously silence the exhaust and tune the stroke speed of a pneumatic cylinder.

Application Guide

• Solenoid Valves: Install on ports 3 and 5 of a 5/2-way valve to quiet the tool or cylinder exhaust.
• Air Motors: Reducing the constant roar of air-driven motors in industrial mixing or conveyor systems.
• Pneumatic Presses: Dampening the loud “pop” during the rapid venting of large-bore cylinders.
• Vacuum Generators: Silencing the discharge air from venturi-style vacuum pumps.
