Our 4-bottle aircraft oxygen system service cart comes complete with a booster and regulator for remote (ramp) or in-hangar boosting. The unit uses N2 to drive the O2 booster, or shop air if used in-hangar (100 psi). The 5th-wheel steering provides optimal in-hangar maneuverability by hand, while the heavy-duty running gear and towbar allow for unlimited vehicle towing across the ramp or airfield.

This unit includes everything required to provide O2 service for aircraft (except for the bottles and gas):

• Powder-coated 4-bottle cart with heavy-duty wheels & pneumatic tires 
• OB-30 oxygen booster
• 3-bottle oxygen regulator with 15' delivery hose and combination charge adapter (will fit either of the two standard aircraft connectors)
• 1-bottle nitrogen low pressure regulator with booster and bottle lines
• Hose kits for connecting boosters, regulators, and bottles.

MAIN FEATURES: 

• The frame and chassis are made of welded steel profiles (low carbon steel), on 4 pneumatic wheels with the possibility to move by towing or manual (for this case the drawbar is equipped with handles) 
• The chassis of the cart is equipped with a parking brake on the front wheels, driven by lifting of the drawbar to the upper position. 
• The cart is adapted for installation of Russian nitrogen cylinders (GOST 94973), for 2 or 4 bottles. Standard bottle connection has thread G3/4, another one, upon additional request. 
• The cart is equipped with a bottles locking system. 
• To increase corrosion resistance, the body and chassis are covered with anti-corrosion treatment before painting, and then coated with powder paint. 
• Cart delivered without bottles. 
• Cart can be supplied with a cover to protect it from precipitation (snow and rain), upon additional request. 
• For safety reasons, first of all fire protection, regulators, manometer bodies and other elements are made of brass. Somewhere brass covered with a layer of nickel. 
• To make N2 service for aircraft, high and low pressure hoses are equipped with adapters with M14 thread step 1, for connecting filling equipment.
• High and low pressure circuits can be equipped with special adapters (upon request) for inflating tires, to service the strut and etc.:

1. Adapter 2755 with maximum pressure up to 5000 psi (345 bar) 
2. Adapter 6116 with maximum pressure up to 3000 psi (207 bar) 

• The low pressure circuit is equipped with pressure gauges and a pressure regulator with a range of 0–30 bar (0–435 psi). 
• The high pressure circuit is equipped with pressure gauges and a pressure regulator with a range of 0-250 bar (0-3625 psi). 
• The high pressure circuit can be equipped with an NB-45 booster. (The booster allows you to extract gas from a bottle at a pressure of 14 bar, whereas without a booster gas can be removed from the cylinder only when a pressure of approximately 69 bar is reached) 
• The high pressure circuit is equipped with an ORV system (overpressure relief valve).
• NB-45 booster can pump and maintain pressure - up to 310 bar (4500 psi) 
• The booster can be powered by compressed air or by nitrogen from bottles. 
• Cart can be supplied combined: for refilling, both nitrogen and oxygen.
