Product detailed description
50 l · 9 bar · 65 dB at 4 mThe biggest reserve in the quiet range. The OS20P-1.5-50CM has a horizontal 50 l tank and still weighs only 32 kg: a decorating gun, a ratchet wrench or long blowing off draw on it without the pump starting straight away, and the two pistons of the 1.5 kW pump at 1,420 rpm top it up oil-free to 9 bar at their leisure between jobs — 85 dB Lwa, 65 dB at 4 m. In a studio or a workshop it stands by the bench, wheels out to the car and runs from an ordinary socket.
When fifty litres makes sense with a quiet pump
The tank does not add displacement, but it gives the pump time — and with a quiet machine, peace as well: from fifty litres a decorating gun or a tyre inflator doing all four wheels draws air for longer before the pressure drops to the switch threshold. The pump then runs in longer cycles with longer pauses, so it starts less often and you hear it less often. The price is a machine 81 cm long that weighs 32 kg; round the workshop it goes by the handle, into the car with two of you. If you want an impact wrench or to spray a whole car on those fifty litres, you need a stronger pump and a continuous draw — that is another range altogether.

Machine details



Where next if the OS20P-1.5-50CM is not the right fit
If half the reserve will do and you want to save eight kilos, take the OS20P-1.5-24CM. If you need a fifty for an all-day draw in the workshop, go for an oil-lubricated pump in an enclosure from the sound-insulated ABAC Silent range, or for more air to the oil-lubricated ABAC Line range. How it differs from the six and the twenty is on the Super Silent OS range page; if you are after a fifty regardless of brand, choose among compressors with a 50 l tank.
Values apply to a 230 V / 50 Hz supply. Noise is given as the sound power level Lwa and the sound pressure at 4 m from the machine. The machine is built for intermittent duty, not for continuous operation.
Ventilek advises
Fifty litres gives the quiet pump long pauses — the machine that starts up least often of all six.

The company ABAC has been one of the most important manufacturers of piston compressors on the world market since its establishment in 1980 . Currently, the brand ABAC is owned by ATLAS COPCO, the largest compressor manufacturer in the world and is part of the multinational group PAD (Professional Air Division). The goal of the ABAC brand is to become a world leader in the development, production and sale of piston compressors.

Production at company ABAC
ABAC compressors are manufactured in 5 production centers around the world, with an annual production of almost 2 million compressors. The brand's parent plant ABAC in Turin, Italy employs around 250 employees and is primarily focused on the design and production of professional V-belt compressors with a daily production capacity of over 600 machines. The ABAC plant also has extensive warehouse facilities with several thousand compressors available for immediate delivery.

Innovative concept
ABAC does not only mean compressor production. We are directly involved in the development of key innovations and advanced solutions and set trends in the compressor market. The efforts of our designers have resulted in, for example, an aerodynamic pulley housing for temperature reduction of up to 35°C, the revolutionary XPAND hose reel compressor or the PRO LINE ZERO oil-free compressors with V-belts. In the ABAC program you will always find the most modern and unique solution for compressed air production on the market.

A modern solution
We are a modern company that is aware of the current trends around us. We are bringing advanced technologies to the compressor industry, such as the use of QR codes and the AIR TUBE app to make it easier for the user of our compressor to access the information they need. We use social media, chat and multimedia instead of traditional marketing and documentation formats. With compressors ABAC you will always have convenient access to all the necessary information.

Compressor program
In the supplier program of the ABAC brand you will find 100%. The basic range includes 100% from small portable compressors for home applications to larger stationary compressors for permanent deployment.
