Vortex Tube Cold End Muffler

Vortex Tube Cold End Muffler

The Supreme Air Products™ Cold End Muffler is specifically engineered to silence the high-frequency “hiss” generated by high-velocity cold air discharge. Unlike standard mufflers that can create back-pressure and degrade cooling performance, our cold end mufflers feature a high-flow design that ensures your Vortex Tube or Cold Air Gun operates at peak thermal efficiency. By maintaining a comfortable and OSHA-compliant noise level, these mufflers are essential for laboratory settings, quiet assembly areas, and close-proximity operator workstations.

Key Features & Benefits

  • Targeted Noise Attenuation: Specifically tuned to dampen the specific decibel frequencies produced by sub-zero airflow, transforming a loud “jet” sound into a soft, manageable breeze.
  • Preserved Cooling Capacity: The internal geometry is designed to prevent air turbulence. This ensures that the cold air exiting the muffler maintains its low temperature and velocity for maximum spot-cooling impact.
  • Low-Profile Design: Compact and lightweight, these mufflers do not add significant bulk, making them ideal for use on robot arms or within tight machine enclosures.
  • OSHA Compliance: Helps your facility stay within regulated noise exposure limits, improving worker safety and focus.

Selection & Installation Guide

  • Small Vortex Tube Muffler: Features a 1/4″ NPT Female thread at the discharge end. This model is designed to fit all 1/4″ NPT Point Hose Kits, allowing for directed, silenced airflow in tight spaces.
  • Medium Vortex Tube Muffler: Features a 3/8″ NPT Female thread at the discharge end. This model is the industrial standard for our Medium Vortex Tubes and fits all 3/8″ NPT Point Hose Kits for high-capacity cooling applications.
  • Ice Prevention: In high-humidity environments, ensure the muffler is kept clear of frost buildup. If the internal media becomes saturated with ice, simply allow it to thaw or blow it out with dry compressed air to restore full flow.
  • Modular Setup: These mufflers can be installed directly onto the product and be used with Flexible Single Point Kit or Dual Hose Point Kit.
