V07T016A-BLDC-SH Two-Stage Helium Scroll Pump

Multi-stage scroll technology from Air Squared allows for higher pressure ratios in a compact, lightweight, and efficient design. Typically used by Air Squared in vacuum pump designs that require low absolute pressure, multi-stage scroll technology can also be used to compress gases from low inlet pressures to a higher discharge pressure.

The V07T016A-BLDC-SH was designed to compress helium from a low inlet pressure to a discharge pressure above ambient. The application had a small space envelope and minimal power budget relative to the pressure ratio. The multi-stage configuration greatly reduced size and power consumption compared to a traditional single-stage design. Air Squared also incorporated a semi-hermetic sealed motor configuration that seals the working fluid from ambient.
