The 450H Hard-Mount Automatic comes with a built-in, moisture resistant ON/OFF power switch. The trigger control function eliminates the need to turn the compressor OFF and ON between each tire fill, making multi-tire inflation a breeze and allowing you to check tire pressure during inflation by simply releasing the inflation gun trigger. It features a heavy duty stainless steel leader hose with a 1/4” quick connect stud for hookup to a coil hose and insulated wiring for simple installation. Comes with the carrying bag if you choose not to mount it.

These compressors are full duty, i.e. ou can run it basically forever for airing up tires after they have been aired down for use in soft sand. If you are looking at this ad, you know that Viair is a respected name in the compressor world.

This is brand new in the box, unopened. VIAIR lists the price at $519.95 and Amazon is selling it for $423.76 plus tax. Tax is included in my selling price.
