Technical Specifications

Installation Requirements

This is a tankless power unit, not a complete compressor with an integrated air tank. A compatible tank and pressure switch are required for operation. Depending on the installation, additional components such as a check valve, discharge line, fittings, and vibration pads may be needed.

Performance Note

Actual system performance depends on the installation, tank configuration, operating conditions, and connected equipment. Verify electrical requirements and compatibility with the manufacturer before installation.
