Tips: What are the Features of ATO 40:1 Air Pressure Booster?

ATO 40:1 air pressure booster it is driven by compressed air and does not require electricity when connected to a common air compressor.
In order to prolong the service life of the pump, the driving air pressure should not be higher than 8 bar.
No air lubricator is required.
When the pressure reaches 80 MPa (11600 psi), there is no separation between the hydrocarbon free air and gas parts
Every air booster is built in cooling system.

Existing reviews of 40:1 Air Pressure Booster, 15-320 bar (217- 4641 psi)

It has shown dependable performance in daily industrial use

Solid build and very reliable in use. Pressure boosts smoothly and stays stable during testing, making gas filling and pressure checks much more efficient and trustworthy.
