Exhaust silencing

Production

The modern standards of labor protection require quite strong norms of noise at work places. So, pneumatic compressors need to be equipped by good mufflers to reduce the noise. ALUPOR™  offers cheap effective solutions with low flow resistance:

Special silencers for pneumatic motors / engines / screwdrivers

ALUPOR™  closely cooperates with Russian company – ZAO "Instrum rend"  that uses products of Ingersoll Rend in their designs of pneumatic equipment.  They successfully implemented silencers with ALUPOR™ noise absorbing element for pneumatic motors instead ones with fiber noise absorbing elements. As the  results there  were dramatically increased durability of silencers at the same noise reduction characteristics. Also, contrary to conventional elements, ALUPOR™ ones may be regenerated. If you want to bye  such silencers please refer to our partner ZAO "Instrum rend"
