ABAC Tech industrial compressors: piston machines for continuous duty
ABAC Tech · industrial range · S1 100 %An ordinary workshop compressor has an S3 motor — after a while it has to stop and cool down. ABAC Tech is built the other way round: an S1 motor at a 100% duty cycle may run without a break as long as it is cooled. ABAC Tech industrial compressors are eight branches and 50 machines from 1.5 to 15 kW that differ in three things — whether they use oil, how many bar they reach, and whether they stand on a tank or only on a carrying frame.
Three questions that decide the choice
All eight branches share the same industrial base: an S1 motor, a cast-iron pump and running without pauses for cooling. They differ in this.
1. May there be oil in the air?
Lubricated machines deliver more air for the same motor power and cost less to run — for a workshop, a tyre service, hand tools. Oil-free machines are needed wherever oil would be a problem: paint shops, food production, laboratories, healthcare. The range has 36 lubricated and 14 oil-free machines.
2. How many bar do you need?
Ordinary tools are happy with 10 bar — that is what the single-stage ATL, ATF and ATFS branches do. When the process wants more, the two-stage ATH at 15, 20 or 30 bar takes over: the air is compressed twice and cooled in between. The range has 25 two-stage machines, exactly half.
3. A tank, or just the pump unit?
A complete set on a 90 or 270 l tank is simply put in place and plugged in — there are 17 of those. The remaining 33 are a pump with a motor on a carrying frame: you supply the pressure vessel yourself, but you choose it to match your consumption and the machine also fits where there is no room for a tank.
Lubricated, or oil-free
This is the first fork in the road and there is no way around it: it decides the branch, not the individual machine.
ATL — lubricated, 10 bar
Eleven machines in two branches. The most air per kilowatt in the whole range: 408 to 1,560 l/min at 1.5 to 7.5 kW. Either a bare pump on a frame, or a complete set on a 90 and 270 l tank.
ATF — oil-free, 10 bar
Eight machines in two branches. PTFE piston rings and a ceramic cylinder surface — no oil can reach the air. The output is of the same order as ATL; the price is noise of 102 to 106 dB.
ATFS — oil-free and portable
Six machines. The only branch you can move yourself: 32 to 76 kg, wheels, a handle and a tank from three to one hundred litres. It is also the quietest branch of the range — 88 to 92 dB.
ATH — lubricated, two-stage
Twenty-five machines in three branches. Pressure of 15, 20 or 30 bar for processes that ten bar cannot serve. The strongest machines of the range have 15 kW and draw in 1,716 l/min.
What makes a compressor industrial
Ordinary piston compressors for trade work are meant for a few hours a day in intermittent duty. After a working cycle they have to stand for a while so the operating temperature drops — the whole build follows from that, above all the electric motor marked S3. At a higher load, typically in industry, a different design is needed and a motor built for continuous duty S1 at 100 %. The other parts of the pump unit are dimensioned to match.
An industrial machine costs more to buy than a trade version, but thanks to its lower operating temperature it is more efficient. And because it needs no forced stops for cooling, it produces air even while an ordinary compressor rests. The result: over a shift it delivers more air, more efficiently and at a lower running cost.
One stage, or two
The number of stages is not a marketing figure — it decides how far the machine can compress and how hot it gets doing it.
Single-stage at 10 bar
Twenty-five machines. The air is compressed in one step. A simpler build, fewer parts and the best ratio of air to motor power. All the ATL, ATF and ATFS branches belong here.
Two-stage at 15 to 30 bar
Twenty-five machines. A large low-pressure cylinder pre-compresses the air, an intercooler takes the heat out of it and a smaller high-pressure cylinder brings it to the working pressure. Cooling between the stages is why the machine sustains high pressure continuously.
How much air is left
The higher the pressure, the smaller the share of the drawn-in air that reaches the outlet. On the ten-bar branches it is around two thirds of the intake, on the thirty-bar ones closer to half. That is why machines are not chosen by intake but by delivery at the working pressure.

Ventilek advises
The motor rating plate tells you everything about how much the machine will take. If it says S3 (or a percentage, for example S3 50 %), it is an ordinary compressor that has to stand and cool for roughly half the time. Run it continuously and sooner or later you will burn it out. For two-shift or three-shift operation look for S1: these motors have heavier windings and better cooling, so they can run without a break.
Frequently asked questions
- What exactly does S1 100 % mean?
- It is the motor duty designation according to the standard. S1 means continuous duty: the machine may run without interruption at full output as long as it is cooled. Ordinary workshop compressors are rated S3, where a pause for cooling has to follow after a certain running time — with S3 50 % that is about half the time. You can read the duty on the motor plate.
- Will an industrial compressor really run nonstop?
- Yes, provided its cooling is taken care of, which means an air supply and a sensible room temperature. The whole build is made for it: a cast-iron pump, reinforced bearings and cooling sized for continuous load. That is exactly why it produces more air over a shift than a machine that has to rest.
- Should I choose by intake or by delivery?
- By delivery at the working pressure. Intake is the volume the pump draws in; delivery is the air that actually reaches the tool or the process. The gap between them grows with pressure — on ten-bar machines about two thirds of the intake is left, on thirty-bar ones closer to half.
- When does an oil-free machine make sense?
- Wherever oil in the air would be a problem — paint shops, food production, laboratories, healthcare, packaging. Oil-free pump units have no oil charge at all, so checking and changing oil falls away too. The price is higher noise and a somewhat shorter piston-ring life than on lubricated machines.
- Why do some machines have no tank?
- Because customers often choose the pressure vessel themselves — by consumption, by space and by local rules. A pump on a carrying frame also fits where a complete set would not, and it can be connected to a tank you already have. The range has 33 machines without a tank and 17 on a tank.
- What about the noise?
- None of these branches has a sound enclosure, so the values run from 88 to 106 dB of sound power Lwa. The quietest is the portable oil-free ATFS branch (88 to 92 dB); the loudest are the largest oil-free and high-pressure machines. If the machine stands in a room where people work, plan for a separate compressor room or a sound enclosure.
- Does ABAC also make screw compressors for continuous duty?
- Yes, and for a sustained high demand they are usually the better answer. An industrial piston machine makes sense where the draw comes in bursts or where you need more than ten bar. The link to the screw machines is below.
