The Haskel HAA31-3.5-N is a compact, single-stage, single-acting air amplifier that boosts air or nitrogen pressure by a 3.5?:?1 ratio. Drive it with up to 125?psi of shop air and it can output pressures up to 450?psi, making it ideal for applications where small-volume pressure boosting is required such as tire inflation, pressure testing, or air-actuated tooling. With robust construction, variable outlet control, and no electrical or spark risk, the HAA31-3.5-N is a simple, rugged solution for demanding industrial tasks.
- Boosts outlet pressure up to 450?psi from shop air
- Compact single-stage design with 3.5:1 ratio
- No electrical or spark source safe for hazardous environments
- Infinitely variable outlet control via air drive regulator
- Rugged stainless and aluminum construction with long-life seals
