Lightweight ABAC L20N compressors with 1.5 kW

single cylinder · 1.5 kW · 14–33 kg

The lightest oil-lubricated machines in the ABAC Line range: 14, 25 and 33 kg. The single-cylinder L20 pump with a 1.5 kW motor draws in 220 l/min, sits directly on the motor shaft and runs from an ordinary socket. The six-litre version is carried by the handle on the cover and delivers 8 bar; the twenty-four and the fifty ride on wheels and fill the tank to 10 bar. For a nailer, a stapler, inflating, blowing off and a ratchet wrench it is everything a DIYer or a tradesman needs — all three machines are in stock and we service the ABAC brand.

Which L20N — one pump, three tanks

The pump, the motor and the panel are the same on all three. You choose the tank — and with it the cut-out pressure and the way you move the machine about.

The three versions side by side

All three machines have the L20 pump with a 1.5 kW motor, one cylinder, direct drive at 2,850 rpm, a pressure switch, a pressure regulator, two gauges and a DN 7.2 quick coupling; the supply is 230 V / 50 Hz. Noise Lwa is the sound power level; at 4 m from the machine that corresponds to roughly 75 dB sound pressure.

Where the L20N works

Oil, accessories and service

The L20 pump takes ALTAIR PRO mineral oil; the capacity is roughly 200 ml, so the quarter-litre bottle covers a change. The DN 7.2 quick coupling is the same standard as the hoses, guns and tools across our whole range. ABAC belongs to the Atlas Copco group and is one of the brands we repair in our own service workshop.

• ALTAIR ALTP-0.25 oil — The specified mineral oil in a bottle for one change.
• ALTAIR ALTP-1 oil — A one-litre bottle for several changes.
• M7 nailers and staplers — The tools the L20N is made for — air in bursts, a small tank will do.
• spiral hoses — Hoses with DN 7.2 quick couplings from the machine to the tool.
• tyre inflators with a gauge — Accurate tyre inflation — you set the pressure and the gun looks after the rest.
• blow guns — Blowing off the bench, the engine and the tools — a job the six is up to.
• ABAC compressor service — Warranty and post-warranty repairs of ABAC machines in our workshop.

Where next if the L20N is not the right fit

The L20N is the lightest oil-lubricated single cylinder in the ABAC Line range. If you need more air, a longer reserve or, conversely, a machine with no oil, there are alternatives in the Line range and beyond. You will find the whole range, with filters by power, tank and voltage, among all compressors.

• ABAC L25P and L30P oil-lubricated compressors — Stronger single cylinders with 270 and 310 l/min and tanks of 24, 50 and 90 l — for an impact wrench, a sander and a spray gun.
• the ABAC V36 V-twin — Two cylinders and 355 l/min from the same socket — for an impact wrench and a nailer without waiting.
• ABAC SUITCASE suitcase compressors — An even lighter oil-free suitcase for inflating and stapling, when you do not want oil in the car.
• small Black Wind compressors — Cheaper 6–50 l machines for home use.
• the whole ABAC Line trade range — An overview of all the Line ranges, from the suitcase to the V-twin.
• portable compressors with a 6 l tank — Six-litre machines across brands, when weight is what matters.
• compressors with a 24 l tank — Twenty-four-litre machines across brands.
• compressors with a 50 l tank — Fifty-litre machines across brands.
• 230 V compressors — Everything that runs from an ordinary socket.
• semi-professional workshop compressors — Machines for daily work in the workshop across brands.

Frequently asked questions

Why does the six have 8 bar and the bigger machines 10 bar?

The six is set to 8 bar: for a stapler, a nailer, a tyre inflator and a blow gun, which work at 6 to 8 bar, that is enough, and the small tank fills to 8 bar quickly. The twenty-four and the fifty go to 10 bar: the bigger tank holds a reserve and the two extra bar are headroom for a ratchet wrench or a longer hose.

Is 220 l/min enough for a nailer, inflating and blowing off — and what is it not enough for?

It is. Tools with a burst draw take air from the tank and the pump tops it up before you pull the trigger again. Where the L20N stops is a continuous draw: an impact wrench on wheel nuts, a random orbital sander and a spray gun empty even the fifty in no time and the motor then runs without a break — those are jobs for the L25P, the L30P or the V-twin V36. Air displacement is the amount of air the pump draws in; how much of it reaches the tool is explained in our guide to measuring airflow.

Will an ordinary socket cope, and why does the compressor trip the breaker?

Yes — the 1.5 kW motor is single-phase, 230 V / 50 Hz, and runs from an ordinary socket. If the breaker trips, it is usually on start-up: a long thin extension lead or a fan heater on the same circuit pulls the voltage down and the starting current is what trips it. Give the compressor a short heavy-gauge lead and, if you can, a circuit of its own. Thermal overload protection is built into the motor — it cuts the motor out if it overheats.

Which oil, and how often should it be changed?

ALTAIR PRO mineral oil; the capacity is roughly 200 ml. You can see the level in the sight glass on the outside — check it before every use; change intervals and the procedure are shown in the ABAC videos once you scan the QR code on the tank with the AirTube app; oil types and grades are compared in our guide to choosing compressor oil. After work, open the valve under the tank and drain the condensate so the tank does not rust from the inside.

How much does it weigh, and can one person carry the six?

The six weighs 14 kg, the twenty-four 25 kg, the fifty 33 kg. The six you lift with one hand by the handle on the cover and carry up the stairs; the twenty-four you wheel by the handle and one person lifts it into the boot; the fifty rides round the workshop on its wheels, but it is best lifted into the car by two of you.

Oil-lubricated or oil-free — why does the L20N have oil?

The oil-lubricated L20 pump is built for low running costs and simple maintenance: an oil change is a matter of a few minutes and 200 ml. The price is checking the level and a trace of oil in the air, which does not matter for inflating, stapling and blowing off. If you want a machine for the car with no oil to look after, or one that gives clean air, reach for the oil-free SUITCASE or for oil-free compressors.

How long can the L20N run at a stretch?

It is a machine for intermittent duty S3 30%: in any ten minutes the motor may run for no more than three and cools down for the rest. In normal work with a nailer or a tyre inflator you will never notice — the switch only runs the motor to top up the tank. If the motor runs without a break, the tool is too big for this compressor.

All values apply to a 230 V / 50 Hz supply. The machines are built for intermittent duty S3 30%, not for continuous operation. Stock levels change daily.
