Product detailed description
A49B · vertical 270 l · 595 l/min · 11 bar · 400 VThe most powerful Expert machine of the range: 595 l/min on a footprint of 830 × 644 mm. The A49BP-4-270VT fills a vertical 270 l tank to 11 bar with the two-stage A49B pump and a 4 kW motor at 1,400 rpm, noise 97 dB Lwa and 77 dB at 4 m. For a paint shop with one booth or a body shop where the gun and the sander take turns all day.
Why 4 kW on the A49B pump
Four kilowatts are the most the A49B pump will take: 1,400 rpm and 595 l/min, a displacement with which the spray gun in the booth does not wait for the tank. Two-stage compression with an intercooler fills 270 l to 11 bar and the vertical tank does it on 830 × 644 mm of floor — behind the booth door, not across its wall. Upstream of the gun goes a regulator with a filter, which catches the oil and water from the pipework. If you want a cast-iron pump with 653 l/min on the 270 l, move up to the B59B; if you need to wheel the machine between the booth and the prep area, reach for the horizontal version on castors.
Equipment and details
What the A49BP-4-270VT has from the factory
- two-stage A49B pump with an intercooler, oil-lubricated, with an oil sight glass; V-belt drive geared down to 1,400 rpm, belt guard
- three-phase 4 kW (5.5 hp) electric motor, 400 V / 50 Hz, thermal overload protection; automatic stop/start pressure switch with a gauge
- air intake 595 l/min, pressure 11 bar, aftercooler on the pump outlet
- vertical 270 l tank on three legs with holes for bolting down, condensate drain valve in the bottom; air outlet through a ball valve on the side of the tank (regulator, filter and quick couplings at the workstation)
- noise 97 dB Lwa, 77 dB at 4 m
- AirTube QR code on the tank opens service videos; 2-year warranty (extension to 3 years at extra cost), 10 years on the tank against rusting through
Machine details



Where next if the A49BP-4-270VT is not the right fit
One motor size down on the same pump is the A49BP-3-270VT; the same motor, pump and 270 l go into the horizontal A49BP-4-270CT on castors. The cast-iron B59B pump on the same vertical tank is on the B59B-4-270VT. Everything that goes with spraying is summed up in our article on spraying with a compressor; if you are torn between the A and the B, you have all seven side by side in the table of vertical machines.
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. The dimensions are those of the machine without packaging. A piston compressor works in cycles (topping up the tank and pausing), not continuously.
Ventilek advises
A paint shop with one booth and little room: 595 l/min and 270 l at 11 bar behind the booth door on roughly half a square metre — and a regulator with a filter for the gun.

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.
