Product detailed description
B70 · stationary · 270 l · 1,210 l/min · 11 barThe B70 pump on feet with the smaller tank — for pipework where the bursts are evened out by the displacement of the pump, not by the reserve. The B70-7,5-270FT: 1,210 l/min into 270 l at 11 bar, a 1/2" ball valve outlet straight into the pipes: a 7.5 kW motor on 400 V, 1,300 rpm, 196 kg; no castors and no regulator here.
Why a stationary B70 with 270 l
Where the compressor room is small and the draw is big: 270 l is half a metre shorter than the 500 and the B70 pump with 1,210 l/min evens out the bursts on its own. Nothing extra on the machine — a switch with a gauge, a 1/2" ball valve on the outlet, a condensate valve and feet; regulation and filters at the workstations. The noise of 102 dB Lwa (82 dB at 4 m) is another reason for a door between the machine and the people. If your draw gets close to the pump running non-stop, you are at the limit of a piston machine — that is where the screw compressor comes in.
Equipment and details
What the B70-7,5-270FT 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 under a belt guard, 1,300 rpm
- three-phase 7.5 kW (10 hp) electric motor, 400 V / 50 Hz, thermal overload protection; automatic stop/start pressure switch with a gauge
- air intake 1,210 l/min, pressure 11 bar, aftercooler on the pump outlet
- horizontal 270 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 B70-7,5-270FT is not the right fit
Castors, a handle and a regulator on the same pump and tank are added by the B70-7,5-270CT; a bigger tank on feet is on the B70-7,5-500FT. Its place among the six machines on feet is shown on the B59B to B70 range page; the B59B and B60 pumps on an upright tank for a small compressor room are the upright VT versions. A draw without pauses for the whole hall calls for a screw compressor.
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
A small compressor room, a big draw: the B70 on 270 l behind the door and pipes to the people.

ABAC is an Italian compressor brand, founded in 1981 and part of the Atlas Copco Group since 2007. We carry machines from a carry-case compressor you lift with one hand, through workshop piston compressors, to industrial and screw machines for an entire hall.
Besides standard oil-lubricated machines, ABAC also makes oil-free compressors for paint shops and surgeries, soundproofed machines in an acoustic cabinet and engine-driven compressors for building sites. They are complemented by ABAC DRY refrigerated dryers, oils and service kits.

Intake is the air the pump draws in; less of it reaches the tool. For screw compressors the manufacturer states the delivery.
How to choose an ABAC compressor
1. Work out the air demand
Add up the consumption of all tools running at the same time and add a reserve. Compare it with the delivery, not the intake: on piston machines the delivery is roughly a quarter lower.
2. Match the running time
For work with breaks, a Line or Pro Line piston machine is enough. If air has to flow all shift long, choose ABAC Tech with an S1 motor or a screw compressor.
3. Check power and space
Smaller machines run from a 230 V socket, more powerful ones need a three-phase 400 V supply. In the code of an electric piston machine, M stands for a 230 V motor and T for 400 V.
4. Maintain regularly
On oil-lubricated machines, check the level in the sight glass and drain the condensate after work. ABAC piston pumps have service kits: the basic LK1 for yearly and the advanced PK1 for two-year maintenance.
Frequently asked questions
- Who makes ABAC compressors?
- ABAC is an Italian compressor brand founded in 1981. It is based in Robassomero near Turin and has been part of the Atlas Copco Group since 2007. Its production quality is backed by ISO 9001 certification.
- Piston or screw compressor?
- It depends on running time. A piston machine fills the receiver and rests, so it suits intermittent work in a workshop. A screw compressor is built for continuous operation and pays off where air is used all shift long. For its screw machines ABAC states roughly 30% higher energy efficiency and about 20 dB(A) less noise.
- Which ABAC compressors are oil-free?
- The Expert Zero range, the quiet Super Silent OS, the ATF and ATFS versions of ABAC Tech, the Clean Air dental compressors and the SUITCASE carry case compress air without oil. They suit paint shops, food production, laboratories and surgeries.
- How quiet is an ABAC compressor?
- The rating plate shows the sound power level Lwa; 4 m from the machine you will measure about 20 dB less. Silent machines in a cabinet have 81 to 89 dB Lwa, the quiet Super Silent OS 63 to 65 dB at 4 m and the screw compressors 57 to 71 dB(A).
- Do I need a dryer with my compressor?
- Compressed air always contains water that condenses in the pipework. For painting or a long pipe network you need a dryer: the ABAC DRY refrigerated dryer brings the air to a pressure dew point of +4 °C and comes in 17 sizes from 266 to 18,000 l/min. Some Pro Line, Silent and SPINN machines have a dryer fitted at the factory.
- Where do I find the manual and which oil should I use?
- Manuals and service videos open via the QR code on the machine in the AirTube app. ABAC piston machines use Altair and ABAC Pro oils, screw machines Rotair oils, including the food-grade Rotair Foodgrade. The manual tells you which oil your machine needs.
Manuals and service videos for ABAC compressors are in the AirTube app via the QR code on the machine. Technical data are manufacturer figures. ABAC is a brand of the Atlas Copco Group.
