Yes . The Preval vFan air hose is built with 1/4″ NPT female compressor fitting for our vFan regulator for both our 150 feet of ENERGY and our Ultralight compressors. Typically fitting sizes are 1/4″ – 1/2″ we just happen to work with the 1/4″ size.
If your compressor has a fitting that is larger they can go to Home Depot or any other similar retailer and purchase an adapter to pair a different size. Typical cost is a few dollars.
