Product Features

BSL, BSLM, BESL Series (Brass Type)

  • Superior Noise Reduction: Sintered brass construction provides excellent silencing performance to safely vent exhaust air from pneumatic valves.
  • Secure Installation: Features a robust threaded connection for easy, safe, and highly reliable installation on exhaust ports.
  • Flow Control (BESL): The BESL adjustable throttling series allows users to fine-tune the exhaust air volume, effectively acting as a speed controller for pneumatic cylinders.

PAL, PALM Series (Plastic Type)

  • Chemical Resistance: The all-plastic structure offers excellent noise silencing while being highly resistant to corrosion, making it suitable for acid and alkaline environments.
  • Compact Design: Miniaturized size and lightweight structure allow it to be directly inserted into threaded grooves, saving significant space.
