Due to popular demand, JETporter now offers a built in air compressor as an option on all our models. How many times have you been far from the hangar and someone needed air in a low tire. You run back to the hangar and look for an air tank. Shoot! Where is it? You finally find it and it's - - - empty! The last person who used it didn't fill it back up. No problem. Pull your JETporter right up to the airplane, hook up the air line, switch on the pump and low tire situation solved!
