ABAC AS-25S503BM

ABAC AS-25S503BM is a 20 HP single-stage oil-flooded rotary screw air compressor delivering 80 SCFM at 150 PSI on a base-mount frame (no integral tank), wired for 230 V single-phase. The unit weighs 690 lb and lists at approximately $15,344 through specialty industrial distributors. Oil-flooded screw design provides continuous-duty output without the duty-cycle limits of reciprocating piston machines, making it well-suited to manufacturing cells, body shops, and sustained plant-air applications requiring uninterrupted airflow. The simplex configuration pairs with a separately mounted receiver tank sized to the installation. Voltage variant 230/1 (MPN AS-25S503BM); a separate SAP part number 4152028456 is also associated with this model. Key gaps: OEM datasheet URL from abac.com not confirmed, CFM at partial-load pressure points not available, noise level (dB) not published in available sources.
