## High pressure gas boosters

### High pressure and ultra-high pressure gas boosters

Air driven gas boosters HII - ideal solution for high and ultra-high pressure gas supply at relatively low flow rates.

The basic line of gas boosters HII is represented by 42 basic types with variety of modifications.

The product line covers a wide range of operating pressures and allows you to solve multitude engineering tasks.

Many years' experience and production facilities allow Hydraulics International Inc. to offer high-tech solutions for boosting of hazardous gases, ultrapure gases to the maximum permissible pressures applied in engineering practice.

Non-lubricated piston design together with pneumatic drive do not have competitive alternatives when solving some engineering tasks of boosting gases to high and ultra-high pressures with relatively low to zero flows.

- Pressures up to 30,000 PSI for most gases and 5,000 PSI for Oxygen;
- Various models available for vacuum application;
- Easy to install and operate;
- Compact, lightweight design;
- Single or double acting and 2-stage models;
- Double air drives available in single and 2-stage boosters;
- No electrical power required;
- Requires no high pressure seal lubrication;
- Boosters are contaminant FREE;
- Units can be operated in series or parallel;
- Boosters may be mounted in any orientation;
