The Tronair 20-4523-0000 4 bottle cart with booster and regulator is designed to minimize the handling of oxygen cylinders in loading and unloading, transporting and servicing process, and to provide boosted compressed gas for an aircraft.

The high pressure regulator is for regulating booster output pressure from 15 - 2250 psi (115 bar).

The booster provides the capability of boosting remaining lower pressure oxygen from supply cylinders to the required higher aircraft system pressure; up to 2250 psig maximum. The booster system provides high regulated pressure output. The transport cart allows a single operator to load full oxygen cylinders and transport them to service the aircraft, without ever having to lift the cylinders. The unique quality of this cart is the operator never has to lift a cylinder, which can weigh between 120 and 175 lbs., onto the cart. The cart has a very narrow footprint and a tight turning radius allowing for easy maneuverability.

Consumer Requirement: This Oxygen Booster utilizes an air driven pressure amplifier, requiring 145 PSIG maximum air pressure input at 80 SCFM volume.

The cart may be used to supply either internal aircraft systems or portable aircraft bottles.
