Product Description
DESCRIPTION:
FEATURES
1. Two-wheeled, poly-coated steel cart, two sets of double-cylinder straps, air-line hose rack and adjustable pull handle
2. Accommodate 2 or 4 x 60-minute, carbon-wrapped cylinders, supplying air for 2 users at the same time, ensure long time operation.
3. The cylinder can be replaced timely, which will not affect work and can effectively save time.
4. Two cylinders are secured to the unit with the cylinder straps.
5. The standard configuration of medium pressure tubes includes one 40 m main tube and two 10 m branch tubes.
6. The medium pressure tubes can be extended to 90 m according to users' demand, and the air still can be supplied smoothly and comfortably.
7. Flexible connection is adopted for the connection between high-pressure tubes to avoid accidents and effectively prevent the damage of joints caused by collision or friction.
8. The breathing air pressure regulator with large-flow output can ensure sufficient flow of breathing air.
9. High pressure isolation valve and toggle switch allow the user to switch between ordinary or compressed air sources.
10. The unique stainless steel foot brake can make the device stop on the ground with the gradient of 30°.
