Product detailed description
Expert · 270 l · 400 V · 553 l/min · 11 barThree kilowatts with the biggest tank in the range. The A49BP-3-270CT: 270 l of reserve with the two-stage A49B pump and a three-phase 3 kW motor on top — 553 l/min at 1,300 rpm, 11 bar, 142 kg. For a workshop where several tools take turns on one machine and the tank should last as long as possible.
Why 3 kW with 270 l
A 270 l tank at 11 bar is the longest reserve in the range and 553 l/min keeps topping it up: two people with a gun and a sander, or a paint shop where the motor should not start every minute. The machine weighs 142 kg and is nearly a metre and a half long — two front castors with brakes and the handle shift it across a level floor, but do not count on wheeling it about every day. The filter-regulator with a gauge and two quick couplings on the tank neck serves two workstations and catches the condensate. If you want even more air, there is 4 kW with the same tank. Even the biggest tank does not change the noise: 96 dB Lwa, 76 dB at 4 m.
Equipment and details
What the A49BP-3-270CT has from the factory
- two-stage twin-cylinder oil-lubricated A49B pump with an oil sight glass, V-belt drive under a moulded belt guard, 1,300 rpm
- three-phase 3 kW (4 hp) electric motor, 400 V / 50 Hz, thermal overload protection; automatic stop/start pressure switch
- air intake 553 l/min, 11 bar, aftercooler on the pump outlet
- horizontal 270 l tank with a ball valve for draining condensate
- filter-regulator with a gauge and two DN 7.2 quick couplings on the tank neck, two gauges (tank and outlet)
- two front swivel castors with brakes, two rear wheels, closed handle with a rubber grip
- noise 96 dB Lwa, 76 dB at 4 m
- AirTube QR code on the tank opens service videos; 2-year warranty, 10 years on the tank against rusting through
Machine details




Where next if the A49BP-3-270CT is not the right fit
Even more air into the same tank comes from the A49BP-4-270CT; for an ordinary socket it comes as the A49BP-2.2-270CM. Where it belongs among the four machines with 270 l is shown on the A49B range page; the biggest tanks of other brands are among compressors with a 270 l tank. From 270 l it also keeps up long passes with a spray gun.
Values apply to a 50 Hz supply. Air intake is the amount of air the pump draws in; how much of it reaches the tool depends on the pressure and the tank. Noise is given as the sound power level Lwa and the sound pressure at 4 m from the machine. A piston compressor works in cycles (topping up the tank and pausing), not continuously.
Ventilek advises
Three kilowatts with 270 l: the longest reserve at 11 bar when several tools take turns on one machine.

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.
