About this specialty power tool

This is a 12-volt portable air compressor from VIAIR, model 40047, sold as a kit and stated as reaching up to 150 PSI. It is designed for inflating tires and is built as an automatic unit, meaning it can be set to a target pressure and shut off once reached. Its listed name points to use with Class C motorhomes, and it runs on a 12 V supply. It may suit RV owners who want a portable way to top up tires on the road. Before buying, check that the kit's contents match what you need, since the packaging details are not confirmed here, and confirm that the 12 V supply and physical size work with your vehicle and storage space.
