My 10-year-old Campbell Hausfeld 20-Gallon Oil-Free Horizontal 5hp 125psi Air Compressor has run flawlessly. I have it set at 100psi and hit the bicycle ties on my way out the garage door every morning and a gauge is not necessary. When I raced motorcycles, tire changes were done every race weekend saving me about $20.00 each tire when I did them instead of the dealer. The unit has paid for it’s self many times over. Air tools make my auto and motorcycle repairs much easier and faster so I have more time to ride. If you are mechanically inclined and do more then just bicycle repairs or you like to paint, an air compressor would be a practical addition to the garage.
