Product detailed description
B70 · stationary · 500 l · 1,023 l/min · 1,100 rpmA 500 on feet with the B70 pump — the set-up for a compressor room with several workstations on the pipework. The B70-5.5-500FT pairs the B70 pump with a 5.5 kW motor at 1,100 rpm and 1,023 l/min with a horizontal 500 l tank on feet; the air leaves through a 1/2" ball valve into the pipework.
Why this set-up
The B70 pump with 1,023 l/min and a 500 l tank cover pipework with three to four draw-off points: the tank evens out the bursts, the pump tops it up and at 1,100 rpm instead of 1,300 heats up less doing so. On the machine there is only what belongs in the compressor room — a pressure switch with a gauge, a non-return valve at the tank inlet, a condensate valve and a ball valve on the outlet; regulators with a filter go at the workstations. The noise of 102 dB Lwa, 82 dB at 4 m, is one more reason the machine belongs behind the door of the compressor room.
Equipment and details
What the B70-5.5-500FT has from the factory
- two-stage twin-cylinder B70 pump with cast-iron cylinders and an intercooler, oil-lubricated, with an oil sight glass; V-belt drive geared down to 1,100 rpm, moulded plastic belt guard
- three-phase 5.5 kW (7.5 hp) electric motor, 400 V / 50 Hz, thermal overload protection; automatic stop/start pressure switch with a gauge
- air intake 1,023 l/min, pressure 11 bar, aftercooler on the pump outlet
- horizontal 500 l tank on feet with a valve for draining condensate; 1/2" ball valve outlet into the pipework (regulator, filter and quick couplings at the workstation)
- stationary version without castors or a handle — for a fixed spot in the compressor room
- noise 102 dB Lwa, 82 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 B70-5.5-500FT is not the right fit
The same set-up on castors is the B70-5.5-500CT; more air on feet with the B79 pump comes from the B79-7.5-500FT. You get the full 1,210 l/min from the same pump on feet with the standard B70-7.5-500FT. Machines on feet of all brands are compared among stationary compressors; where the air has to be dry already in the pipework, the answer is the version with a dryer.
Values apply to a 400 V / 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 or four workstations on the pipework, the compressor behind the door and a tank that evens out the bursts — that is what the low-speed B70-5.5 on feet is built for.

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.
