ABAC AS-10S503TMD 10 HP Rotary Screw Air Compressor - 131 Gallon Tank Mount with Dryer, 150 PSI, 35.6 CFM, 65 dBA

The ABAC AS-10S503TMD is a complete compressed air station in one package: a 10 HP rotary screw compressor on the quiet 10S air end, a 131 gallon air receiver and a refrigerated dryer, mounted and plumbed as a single factory assembly. It delivers 35.6 CFM at 150 PSI and runs at 65 dBA, quiet enough to sit in the work area instead of a separate compressor room. There is no separate tank or dryer to source, site and pipe, so installation comes down to setting it in place, wiring it and connecting your air line. Power is 208-230-460V three-phase.

Why the three in one package

A rotary screw is rated for continuous duty, so it holds a flat line pressure through a full shift instead of sagging and recovering between jobs the way a piston machine does. The catch is that air leaving any screw comes out hot and saturated, so a dryer is not optional on a system feeding paint, pneumatic controls or precision tools. Buying the compressor, the receiver and the refrigerated dryer as one factory assembly removes the part of the job that usually goes wrong: no separate dryer to size and source, no interconnecting pipe to fabricate, no second set of mounts, and no chance of a dryer undersized for the air end in front of it. The installer lands power and ties into the header. The 131 gallon receiver underneath keeps the screw from short cycling, which is the one duty pattern a screw genuinely dislikes.

How it compares

At 150 PSI this is the middle setting of the three pressures offered on the 10S air end, and on identical hardware pressure and airflow trade directly against each other. The AS-10S253TMD is the same 844 lb package set for 125 PSI at 39.8 CFM, and the AS-10S753TMD runs 175 PSI at 29.9 CFM. Buy pressure only to the level your highest tool actually needs, because every step up costs airflow on the same 10 HP motor. Set against the standard 10 HP package on the same tank, the AS-10503TMD delivers 34.1 CFM at 69 dBA, so the 10S buys about 1.5 CFM more air and 4 dBA less noise, which matters when the compressor shares a room with the people using it. If drying is already handled upstream, the AS-10S503TM is this same 131 gallon build without the dryer at 750 lbs, and the AS-10S503BM is the bare base mount at 454 lbs on a 37 x 28 in footprint for a shop that already owns a receiver. If 35.6 CFM is short of what your tool list draws, the AS-15503TMD holds the same 150 PSI at 46.4 CFM.

Typical applications

Paint and finishing work, production and fabrication floors, automotive and fleet service bays, tire and truck shops, heavy assembly, cleaning and parts preparation, and cabinet and woodworking shops where moisture in the air line causes rejects or tool wear. The integrated dryer removes water before it reaches the distribution piping, which matters anywhere air touches a finish, a pneumatic control or a precision tool. The 150 PSI build is the one to choose when tools, presses or a plant header need pressure above the usual 125 PSI shop standard, and the 65 dBA rating lets it sit on the floor it serves rather than in a dedicated room.
