{"product_id":"guardair-n686-vacuum-cleaner-exhaust-silencer","title":"Guardair N686 Vacuum Cleaner Exhaust Silencer","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFoam insert construction attenuates exhaust noise at the vacuum discharge port\u003c\/li\u003e\n\u003cli\u003eDirect replacement part for worn or missing exhaust silencer foam on compatible GUARDAIR vacuums\u003c\/li\u003e\n\u003cli\u003eFits 55-gallon, 30-gallon, and 15-gallon GUARDAIR pneumatic vacuum models\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.12 pounds for easy handling and stocking\u003c\/li\u003e\n\u003cli\u003eSold individually as a single-piece service component\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with GUARDAIR pneumatic vacuum cleaners in 55-gallon, 30-gallon, and 15-gallon configurations, including model N081DC.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDisconnect 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.
