Precision-engineered pneumatic silencer with integrated flow control, featuring micro-groove diffusion technology for effective noise reduction up to 15 dB. The knurled throttle ring allows single-hand adjustment while maintaining vibration resistance. Optimized for stable flow characteristics across pressure variations.
- Speed regulation in pneumatic cylinder exhaust ports
- Noise suppression for solenoid valve manifolds
- Precision air blow systems in electronics assembly
- Medical device pneumatic circuits
- Food processing equipment exhausts
- Laboratory pneumatic tool outlets
Installation note:
Install vertically with exhaust direction downward. For optimal performance:
- Rotate throttle clockwise to minimum flow position before installation
- Hand-tighten with 1.5-2 N·m torque (use backup wrench on hex base)
- Adjust flow by rotating outer ring - 1 full turn ≈ 25% flow change
