ABAC Tech ATL compressors on a receiver: ready to run
ABAC Tech ATL · on a receiverThe same industrial pumps as in the basic version, only already set on a horizontal receiver. No hunting for a tank, no frame to assemble, no pipework to connect — the machine arrives as a finished assembly, goes onto anti-vibration mounts and is connected. The motor runs in duty type S1, that is a 100% duty cycle: it can run the whole shift with no pause to cool down. Three machines from 2.2 to 5.5 kW with a 90 or 270 litre tank, all at 10 bar.
Three things that decide the choice
All three machines are oil-lubricated, single-stage at 10 bar, direct-driven and run on a three-phase 400 V supply. The pump is the same as in the basic version — what differs is what sits underneath it.
1. How much air will you use?
We look at the air delivered at 10 bar, not at the intake — that is the air which actually reaches the tools. The span is 210 to 576 l/min. Since the motor may run without a break, what counts is the average draw per shift; the tank underneath covers the short peaks.
2. Ninety litres or two hundred and seventy?
The receiver is a reserve for peaks in demand, not for output. 90 litres is enough where the draw is steady and the machine keeps up as it goes. 270 litres earns its place where the draw comes in bursts — sandblasting, longer blowing off, several tools at once — because the motor then cuts in far less often.
3. Will your supply take a direct start?
The most powerful machine carries an X in its code: it runs the motor up through star-delta, so the current surge at start-up is gentler. At five and a half kilowatts on continuous duty that is usually a condition of the supply. The other two start directly.
How to read the machine code
The code has four parts: ATL is the range, the first number is the motor rating in kilowatts, the second the receiver volume, and the letters at the end define the version.
F — stationary on a tank
The machine is set on a horizontal receiver which doubles as its base. It stands on feet with anti-vibration mounts, needs no bolting down and no further structure.
T — three-phase 400 V supply
The whole category runs on 400 V / 50 Hz. An industrial four-pole S1 motor cannot be connected to an ordinary socket, and nobody should try.
X — star-delta
Only one machine in the category has it, the five-and-a-half kilowatt one. The motor runs up in two steps, so the current peak at start-up is markedly lower. Once it is up to speed it makes no difference.
Why an ATL keeps running
What sets it apart from a workshop compressor is not one part but the build of the whole pump. The cylinders are of an aluminium-silicon alloy with heavy finning, the connecting rod is cast so that it carries heat away from the gudgeon pin, and the bearings are greased for life. On top of that a high-capacity fan pushes air straight onto the cylinder heads.
The result is a machine that works at a low operating temperature and does not have to stop to cool down — hence S1 and a 100% duty cycle. The slow 1,500 rpm and the direct drive without belts add fewer parts that can wear: no belts to tension and no pulleys to align.

The delivered figure is the air the machine actually supplies at a working pressure of 10 bar; the intake is the volume the pump draws in. Lwa is the sound power level from the machine plate, Lwp the sound pressure level at a distance of four metres. Dimensions are length × width × height. All figures are manufacturer data.

Ninety litres against two hundred and seventy
The difference between the two tanks shows at a glance: the shorter machine fits beside a workstation, the longer one needs a place of its own — but it covers a bursty draw.
Noise without dressing it up
These machines are loud, and there is no point hiding it: the sound power level Lwa is 99 and 100 dB. This is an open industrial machine with no enclosure at all, built for output and heat removal, not for quiet in the room. It belongs in a machine room, a lean-to or behind a wall, not next to a workbench.
🔴 Be careful comparing with other offers. Catalogues often quote 79 or 80 dB for the same machine — but that is the sound pressure Lwp measured at four metres, which is roughly 20 dB(A) below the Lwa power figure on the plate. Both numbers are correct; they simply measure different things. With us every machine states both, so that apples can be compared with apples.
What all the machines share
S1 motor on a 100 % cycle
A four-pole motor rated for continuous load. It needs no pauses to cool down, which is exactly what separates this range from workshop compressors with an S3 motor.
Direct drive without belts
The pump sits straight on the motor. No belts to tension or replace, and nothing for the drive to lose along the way.
Aluminium-silicon cylinders
Heavy finning carries the heat away and the alloy reduces friction. The V arrangement of the pistons keeps the machine balanced at low speed.
Horizontal pressure vessel
The tank forms the base of the whole machine and stands on feet with anti-vibration mounts. Condensate is drained through a valve at the bottom.
Stainless valves
A stainless valve plate takes the high temperatures and the cyclic load of continuous duty.
Bearings greased for life
The bearings are not greased at service intervals — they are filled at the factory for the whole service life.
Two-year warranty
Every machine in the range carries a two-year warranty.
Ventilek recommends
This is the simplest route to industrial air. Pump, motor and tank arrive as one piece — you stand it on the floor, connect it and go. No hunting for a receiver, no frame to bolt down, no connecting pipework. Choose by tank volume rather than by output: ninety litres for a steady draw, two hundred and seventy for a bursty one. And reckon with the noise — a hundred decibels of sound power is not a machine for a workshop where people work.
Frequently asked questions
- What does S1 mean and why does it matter?
- S1 is the standard designation for a motor duty type: the machine may run continuously at full output as long as it is cooled. Ordinary workshop compressors are S3, which means a period of running must be followed by a pause to cool down — usually about half and half. Leave an S3 machine running non-stop and it overheats, cutting its life to a fraction.
- How big a tank do I need?
- The volume is chosen by the peak draw, not by the output of the compressor. Where the air is drawn steadily, 90 litres is enough and the motor keeps up as it goes. Where the bursts come — sandblasting, longer blowing off, several tools at once — 270 litres pays off, because the motor cuts in less often and the pressure in the pipework swings less.
- How does it differ from the version without a tank?
- In the pump, not at all — it is the same machine with the same output. The difference is that here it is set on a receiver and arrives as a finished assembly. The basic version is bought where you already have a tank or pipework and want to fit the machine into an existing assembly.
- Why does the table show delivered air rather than intake?
- Because the delivered figure is the air that actually reaches the tools at a working pressure of 10 bar. The intake is the volume the pump draws in — on the ATL-2,2 that is 504 l/min against 210 l/min delivered. For choosing a machine the delivered figure decides; we state both so it is clear which is which.
- Is it really that loud?
- Yes. The sound power Lwa is 99 and 100 dB, which is what an open industrial machine with no enclosure does. The figure of 79 or 80 dB that turns up for these machines is the sound pressure at four metres — a different quantity, roughly 20 dB(A) lower. If you need a machine for a room where people work, look for a version in a sound cabinet.
- Does the condensate have to be drained?
- Yes. Water condenses in the receiver and is drained through a valve at the bottom of the tank. The condensate contains oil, so it does not belong in the sewer — it goes to an oil-water separator.
