Gast R5325A-2 Regenerative Air Blower 2.5 Hp 3-phase

Product Description

The GAST R5325A-2 is a three-phase regenerative air blower rated at 2.5 horsepower. It delivers continuous, oil-free airflow using a regenerative impeller design, making it well suited for demanding industrial and commercial pneumatic applications. Operating at 230/460 volts with a full load draw of 6.9/3.45 amps, this blower moves up to 160 CFM and can develop up to 65 inches of water column pressure or 60 inches of water column vacuum. The inlet and outlet are each 1.5 inches. Licensed electricians and mechanical contractors handle installation and wiring on three-phase units of this class.

The R5325A-2 is used in applications that require sustained positive pressure or vacuum, including aeration systems, pneumatic conveying, wastewater treatment aeration, material handling, and industrial process equipment. Its regenerative design provides pulsation-free airflow without lubrication, reducing maintenance requirements in continuous-duty environments. Both CE and CSA certifications allow use in North American and applicable international installations.

Installation Notes

Installation of this three-phase blower must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all power before making any electrical connections or servicing the unit. Confirm supply voltage matches the selected motor winding tap before energizing. Ensure inlet and outlet piping is properly supported and does not impose mechanical stress on the blower housing ports.
