ABAC AS-15253TM 15 HP Rotary Screw Air Compressor - 131 Gallon Tank Mount, 125 PSI, 52.1 CFM, 69 dBA

The ABAC AS-15253TM is a 15 HP rotary screw air compressor shipped on a 131 gallon air receiver, built for shops that need steady air through a full shift rather than the stop and start cycle of a piston unit. It delivers 52.1 CFM at 125 PSI and runs at 69 dBA on 208-230-460V three-phase power. Because the screw unit and the tank arrive as one assembly, installation comes down to setting it in place, wiring it and connecting the air line.

Why the tank is part of the machine

A rotary screw is built to run continuously, so the receiver is not there to give the compressor a rest the way a piston machine's tank is. It is there to absorb short bursts of demand, to hold line pressure steady when several tools trigger at once, and to knock some of the condensate out of the air before it reaches your piping. Buying the tank already mounted removes the sizing question, the second footprint and the interconnecting pipe, and it is why most shops replacing a worn out 80 gallon piston unit go straight to a tank mount screw.

How it compares

Within the 15 HP AS-B frame the mounting and the pressure move independently. The AS-15253BM is the same air end with no tank at 478 lbs, for a shop that already owns a receiver, and the AS-15253TMD is this machine with a dryer built onto the same frame at 871 lbs. Moving up in pressure trades airflow in the identical cabinet: the AS-15503TM gives 46.4 CFM at 150 PSI and the AS-15753TM gives 41.7 CFM at 175 PSI. On volume, the 10 HP AS-10253TM delivers 36.4 CFM on the same tank and the 20 HP AS-20253TM steps up to 60.6 CFM at 71 dBA. Pick the pressure first, because every step up costs airflow, then size the air end to the tool list.

Typical applications

Production and fabrication floors, automotive and fleet service bays, tire and truck shops, cabinet and woodworking shops, and any operation where a reciprocating compressor is working too hard to hold line pressure. At 69 dBA the package is quiet enough to sit near the point of use instead of in a separate compressor room, and the 131 gallon receiver carries it through short bursts of heavy demand without short cycling.

What to pair it with

The compressor and the receiver come as one unit, so what is left is drying, filtration and drainage. At 52.1 CFM the usual match is a refrigerated dryer rated above that figure, such as the ABAC COOL 65, with a condensate drain on the tank so the water it knocks out actually leaves the system. If you would rather have the dryer factory piped and wired onto the frame, buy the AS-15253TMD instead and skip the second install.
