Ventilation silencer EVO

dischargeventilationhigh-pressure

Product overview
The EVO Vent Silencer from IMI Fluid Kinetics is a vent-to-atmosphere noise control solution engineered for industrial systems. It reduces high‑velocity discharge and atmospheric vent noise through a thick shell and high‑performance acoustic fill, and is designed for reliable, low‑maintenance operation in harsh environments. The unit features an axial flow body with flexible diffuser capacity and multiple outlet connection options, optional stainless steel baffles for extended life, a built‑in lifting bar for installation, and an external drain to prevent rainwater build‑up.

Key benefits

• Reduces venting noise with a rugged insulated shell and high‑performance acoustic fill
• Withstands extreme site conditions using corrosion‑resistant material options and flexible diffuser configurations
• Simplifies handling and maintenance via integrated lifting bar and external body drain
• Can be tailored to site needs including snow, sand and wildlife protection

Features

• Axial flow body design
• Pressure rating: ANSI 150–2500
• BWE end connections (standard)
• Carbon or stainless steel shell
• Carbon or stainless steel baffles and diffuser (optional)
• Long‑strand fibreglass acoustic fill for high‑temperature and moisture resistance
• Operating temperature capability approximately -50°C to 565°C (material dependent)
• 1" NPT drain connection
• Integrated lifting bar for installation
• Designed to ASME B31.1 / Section VIII Div. 1

Additional product details
The EVO silencer is available in multiple materials (carbon steel, chrome moly, stainless steel) and body configurations (axial flow, side inlet). It is intended for use with gases and steam and can be supplied with various diffuser capacities and outlet connection options to suit site conditions and acoustic requirements. Shell, baffle and fill selections are chosen to maximise service life and simplify maintenance in demanding environments.
