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

The ABAC AS-15253TMD is the all in one version of ABAC's 15 HP AS-B screw compressor: compressor, 131 gallon receiver and refrigerated air dryer built onto a single frame and shipped as one machine. It delivers 52.1 CFM at a 125 PSI maximum and runs at 69 dBA on 208-230-460V three-phase power. Because the dryer is already plumbed and wired into the package, there is no second unit to size, site, pipe or power, and the air leaving the discharge is already dry. At 871 lbs in a 76 x 27 x 62 in footprint it occupies roughly the floor space of the tank alone.

What the dryer adds to the package

ABAC lists the same compressor and tank without the dryer at 776 lbs, so the refrigerated dryer accounts for roughly 95 lbs of the 871 lb total and none of the floor space: the cabinet and the 76 x 27 x 62 in footprint are identical either way. That trade matters more than it sounds. A 15 HP screw pushing 52.1 CFM of warm saturated air into cool shop piping will drop a real volume of water somewhere, and the only open question is whether it comes out at the machine or at the drops above your benches. The factory dryer is matched to the 52.1 CFM this unit actually produces, so there is no sizing exercise, no second electrical circuit, and no mismatch between a compressor bought this year and a dryer added later.

Why the 125 PSI build

The AS-15 cabinet is sold at three pressures and the airflow moves with it: 52.1 CFM at 125 PSI, 46.4 CFM at 150 PSI, and 41.7 CFM at 175 PSI, all from the same 15 HP motor and the same frame. Choosing 125 PSI buys about 25 percent more air than the 175 PSI build, which is the right trade whenever the tool list works at 90 to 100 PSI at the point of use, as most sanders, impact tools, spray guns and plasma torches do. Step up to 150 or 175 PSI only when a specific machine calls for it or a long run of undersized pipe eats the pressure on the way out, because header pressure you do not need is horsepower you pay for every hour the compressor runs.

How it compares

Within the 15 HP AS-B range the pressure, the mounting and the dryer all move independently. The AS-15253TM is the same compressor and the same tank without the dryer, at 776 lbs, and the AS-15253BM is the bare base mount machine at 478 lbs for shops that already own a receiver. Moving up in pressure trades airflow: the AS-15503TMD gives 46.4 CFM at 150 PSI and the AS-15753TMD gives 41.7 CFM at 175 PSI, both in the identical cabinet. If the tool list calls for more air at the same 125 PSI, the AS-20253TMD steps up to 20 HP and 60.6 CFM at 71 dBA. Pick on pressure first, then on CFM, then on whether the tank and dryer come in the package or get bought separately.

Typical applications

At 52.1 CFM this is a whole shop machine rather than a bench supply: a body shop running a booth alongside air tools, a cabinet or millwork shop on orbital sanders and nailers, a fabrication shop feeding a plasma table, or a small production line on pneumatic controls and instrument air. Dry air is the thread running through all of them. Paint, powder coat, plasma consumables and air logic fail in the same way when water reaches them, and here they are all fed from a discharge that has already passed through the dryer. The 131 gallon receiver gives the package room to ride out bursts of heavy demand without short cycling, and at 69 dBA it is quiet enough to sit near the point of use instead of in a dedicated compressor room.

What to pair it with

The dryer and the receiver are already in the box, so what is left to decide is drainage, filtration and pipe. Put a condensate drain on both the tank and the dryer so the water they knock out actually leaves the system, add coalescing and particulate filtration downstream if the air feeds paint or instruments, and run aluminum compressed air pipe so the distribution side does not put rust back into air you just dried. Keep an oil, oil filter and separator element set on the shelf and let the controller's programmed maintenance schedule tell you when they are due.
