SMC VCHN Series Pneumatic Silencer, 35dB Noise Reduction, 1 1/2 inch R Connection Size - VCHN4-14

This pneumatic silencer reduces exhaust noise and protects downstream components in compressed-air systems. Constructed from corrosion-resistant stainless steel, it is designed for threaded installation into R-standard ports and performs across typical workshop temperatures. The unit is suited to industrial environments where controlled venting and noise attenuation are required without compromising flow integrity.

Features and Benefits:

• Reduces acoustic emissions by 35 dB for quieter operation
• Withstands up to 50 bar allowing high-pressure system use
• Operates between 5°C and 80°C across duty cycles
• Male R-threaded connection ensures secure threaded fit
• Thread size 1 1/2 in R permits robust pipework integration
• RoHS compliance supports safe material selection

Applications

• Suitable for compressor exhaust lines requiring noise control
• Ideal for pneumatic tool exhaust in manufacturing plants
• Used with high-pressure actuators needing vent silencing
• Can be used for laboratory test rigs with threaded ports
• Practical for maintenance rigs where corrosion resistance matters

What connection type does it require for installation?

It fits into a threaded R port using a male thread and mates with standard R female fittings.

How compact is the unit for confined installations?

The body spans 240mm overall length and has a 74mm external diameter, enabling installation in restricted runouts.

How does material selection affect longevity in harsh environments?

Stainless steel construction provides resistance to corrosive atmospheres and extends service life compared with non‑metallic alternatives.

Can the silencer cope with fluctuating system pressures?

Yes

it is rated to tolerate pressures up to 50 bar, accommodating intermittent high-pressure events without degradation.
