Air Squared is working to accommodate the growing demand for next-generation compressor technology for electric vehicles, developing oil-free scroll solutions for commercial air braking, auxiliary air systems, and recently, autonomous vehicle sensor cleaning.

Autonomous vehicles utilize sophisticated sensors to track traffic movements and vehicle positioning. Similar to how a windshield requires cleaning after accumulating particulates and bugs from normal driving, sensors also require periodic cleaning to function properly. Cleaning with controlled air bursts requires a lightweight, quiet, and low-maintenance air compressor.

Air Squared designed the P14H030A-BLDC for scalability, using a simplistic design approach and keeping part count to a minimum. The compressor can accommodate ambient temperatures between -20 ºC and 100 °C and uses a unique tip seal design for extended life and reliability.
