ABAC AS-10S253BM 10 HP Rotary Screw Air Compressor - Base Mount, 125 PSI, 39.8 CFM, 65 dBA

The ABAC AS-10S253BM is the quiet, higher output 10 HP machine in the AS-B range. It delivers 39.8 CFM at a 125 PSI maximum and runs at just 65 dBA, which is about 4 dBA below the standard AS-10 and quiet enough to leave on the shop floor near the point of use instead of walling it into a compressor room. This is the base mount version, so it ships without a receiver and plumbs into an air tank you already own or one sized to your demand. At 454 lbs in a 37 x 28 x 40 in cabinet it uses the wider AS-15 frame rather than the compact AS-10 frame, which is where the extra airflow and the lower noise come from. Power is 208-230-460V three-phase.

Why a screw instead of another piston

A rotary screw is built for continuous duty, so it holds a steady line pressure through a full shift rather than recovering between jobs. That is the reason to move off a piston machine that is cycling hard, running hot and filling the room with noise. The AS-B air end is a fully integrated aluminum block with vertical oil separation, which keeps oil carryover and condensation low, and ABAC pairs it with an energy efficient motor and a digital controller so the service schedule lives on the panel rather than on a clipboard.

How it compares

Within the AS-B range the pressure, the airflow and the mounting move independently. The AS-10S503BM is the same machine set for 150 PSI at 35.6 CFM, and the AS-10S753BM reaches 175 PSI at 29.9 CFM, all three in the identical 454 lb cabinet. Against the standard AS-10253BM at the same 125 PSI, this unit gives 3.4 CFM more air and runs 4 dBA quieter for 35 lbs more weight. Stepping up, the AS-15253BM reaches 52.1 CFM in the same 37 x 28 x 40 in footprint. If you do not already own a receiver, the AS-10S253TM puts the same air end on a tank mount receiver, and the AS-10S253TMD adds an integrated dryer to that package. Pick on CFM first, then on pressure, then on whether you want the tank and the dryer in one skid.

Typical applications

Production and fabrication floors, heavy assembly and production line work, automotive and fleet service bays, tire and truck shops, cabinet and woodworking shops, and cleaning and surface preparation. At 39.8 CFM it will carry several air ratchets, an orbital sander and a plasma cutter on the same line, or keep a two to three bay shop fed through a full shift. The 65 dBA rating is the reason to choose this one over the standard AS-10 when the compressor has to share space with the people using it.

What to pair it with

Base mount is the starting point for a modular compressed air system. Size a receiver to your demand and pipe it downstream of the compressor, then add moisture control if the air goes to paint, tires or anything that hates water. At 39.8 CFM the ABAC COOL 50 refrigerated air dryer is the matching size with headroom, and it runs on 115V so it plugs in beside the compressor without new wiring.

Call us with your tool list and duty cycle and we will confirm receiver sizing, connection sizes and installation clearances before you pipe it in.
