Silencer/reclassifiers are integral silencer and oil separation devices.
When installed at the exhaust ports of pneumatic valves they reduce exhaust
noise and capture lubricants contained in the exhausting air.
They are used on valve-cylinder applications and on air tools with piped exhausts.
FEATURES:
• Exhaust noise is reduced to 80 to 85 dBA under standard steady-state test
conditions
• Peak impact noise is reduced to 106 to 108 dBA
• Both a drain cock and a 1/8 tube fitting are supplied for the manual or automatic
draining of accumulated liquids
