About this specialty power tool
The VIAIR 450P is a 12-volt portable compressor kit designed to inflate tires, with a stated capacity for tires up to 42 inches. It is built as an automatic model, meaning it can be set to a target pressure and shut off once that level is reached, and it is sold as a kit rather than a bare unit. This compressor suits RV owners and drivers who want an onboard way to top up large tires on a 12-volt supply.
