Quality Electric Air & Specialty Gas Boosters

Two Stage Pump
Models 5000A-2, 6000A-2 & 7000A-2

 Description
The Masterline Electric Booster Pump is used for pumping Breathing Air, Oxygen, Argon and Helium. It allows users to fill breathing air cylinders to 6000 PSI and oxygen cylinders to 4500 PSI from low pressure supply cylinders. The Booster has a 10:1 boost ratio.

Currently we are specializing in a high quality Oxygen Booster for Drager and BioMarine Rebreathers which is being marketed world wide. Whether being used in a facility or in the field you will find them easy to operate with minimal maintenance and a low noise level of 77dB at 3 feet.

Used to pump down oxygen, helium, and argon cylinders with a 10:1 boost ratio. Allows you to pump down cylinders to 300 PSI when filling to 3000 PSI. Has a 15:1 boost when filling small cylinders.  

 Maintenance

Masterline boosters are completely oil-free and use only two low-friction dry seals. The seals can be replaced in about 20 minutes by anyone with only a few tools. The piston guide is the only other part that needs replacement after several years of services. This is done by simply sliding off the piston.
