ABAC AS-15753BM 15 HP Rotary Screw Air Compressor - Base Mount, 175 PSI, 41.7 CFM, 69 dBA

The ABAC AS-15753BM is a 15 HP base mount rotary screw air compressor for shops that have outgrown a piston unit and need steady air through a full shift. This is the 175 PSI build, delivering 41.7 CFM at 69 dBA, for plants running tooling or processes that specify a higher line pressure than a standard 125 PSI machine will hold. Base mount means the unit ships without a receiver, so you plumb it into an air tank you already own or size a tank to the job. At 478 lbs in a 37 x 28 x 40 in cabinet it sets down in about the space a 60 gallon vertical piston compressor already takes up. Power is 208-230-460V three-phase.

Why a screw instead of another piston

A rotary screw is rated for 100 percent duty, so it holds line pressure through a full shift instead of 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, paired with an energy efficient motor and a controller that handles programmed maintenance, so the service schedule sits on the panel rather than on a clipboard. ABAC designs the air end for limited air loss and low oil consumption, which keeps running cost and oil carryover down over the life of the machine. At 69 dBA it is quiet enough to sit in the working space rather than in a closet built to contain it.

Why 175 PSI

Most shop air tools are specified at 90 PSI at the inlet, and a 125 PSI compressor covers them with room to spare. The 175 PSI build exists for the cases that do not fit that pattern: long runs of undersized pipe where line loss eats the margin, a process or test rig that specifies a higher supply pressure, or a plant standardizing every compressor on one higher setpoint. Buying pressure you do not need costs airflow, because the same 15 HP air end gives up CFM as discharge pressure rises. Check what your highest pressure tool or process actually calls for at the point of use before choosing this build over the 125 PSI version.

How it compares

Pressure and airflow trade against each other on the same 15 HP frame. At 175 PSI this unit delivers 41.7 CFM, against 46.4 CFM from the 150 PSI AS-15503BM and 52.1 CFM from the 125 PSI AS-15253BM, all three in the same 478 lb cabinet. Within the 175 PSI line the 10 HP AS-10S753BM carries 29.9 CFM and the 20 HP AS-20753BM carries 48.5 CFM, with this 15 HP frame between them at 41.7 CFM. If you do not already own a receiver, the same 175 PSI air end is sold as a tank mount at 776 lbs, and as a tank mount with an integrated dryer at 871 lbs.

Typical applications

Production and fabrication floors, automotive and fleet service bays, tire and truck shops, cabinet and woodworking shops, blasting and finishing booths, and any operation running a tool or process that calls for more line pressure than a 125 PSI machine will hold. At 41.7 CFM it will carry several bays of air tools, a plasma table, or a blast or finishing setup without the pressure sagging when a second operator pulls a trigger.

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 41.7 CFM the usual pairing is a COOL series dryer rated above that figure, such as the ABAC COOL 50 refrigerated air dryer, whose 232 PSI maximum working pressure covers a 175 PSI system and which runs on 115V so it plugs in beside the compressor. Oil, oil filter and separator element are the service items, so keep a spare set on the shelf.
