Guardair N686 Vacuum Cleaner Exhaust Silencer

Product Description

The GUARDAIR N686 is a replacement exhaust silencer designed for pneumatic wet/dry vacuum cleaners. It reduces exhaust noise during vacuum operation by incorporating a foam insert that attenuates airflow sound at the exhaust port. This component is a direct service part intended for units that have degraded silencer performance due to a worn, clogged, or missing foam insert. Installation is straightforward and typically requires no special tooling. HVAC technicians, plumbers, and general tradespeople who rely on air-powered vacuums for job-site cleanup will find this a practical consumable replacement to keep on hand.

The N686 exhaust silencer is compatible with GUARDAIR pneumatic vacuum cleaners in the 55-gallon, 30-gallon, and 15-gallon size classes, including model N081DC. It is suited for use in commercial and light industrial settings where compressed-air-driven vacuums are standard equipment for debris, liquid, and chip recovery tasks.

Installation Notes

Disconnect the compressed air supply to the vacuum unit before removing or installing the exhaust silencer. Locate the exhaust port on the vacuum body and remove the existing silencer or foam insert before seating the replacement. No special tools are required for this service. Always verify the air supply remains isolated until the silencer is fully seated and the unit is reassembled.
