Product detailed description
2 × B60 · 900 l · 1,654 l/min · 11 bar · 400 VB60 pump units on the biggest tank of the range. The B60-2x5.5-900FT: the same two cast-iron B60 pump units with 5.5 kW motors and a displacement of 1,654 l/min at 1,400 rpm, but a horizontal 900 l tank at 11 bar; noise 100 dB Lwa, 80 dB at 4 m. For a production shop with long peaks and pipework across the whole hall, where the 900 has something to hold and both pump units run longer at a stretch instead of frequent short starts.
Why a 900 under two B60 pump units
We carry the same B60 pump units with 5.5 kW motors on a 500 l tank as well; 900 l does not add displacement, but it changes the rhythm of the machine. It takes longer for the pressure in the tank to drop to the cut-in value, so the pump units start less often, and once they run, they run longer at a stretch — which does them more good than short cycles. Pipework across a hall with long runs has something to draw on even while both pump units are standing still. You pay for it in floor space: a 2,070 × 800 mm footprint and 1,570 mm of height instead of 2,030 × 670 × 1,400 mm on the 500.
Equipment and details
What the B60-2x5.5-900FT has from the factory
- two two-stage B60 pump units with cast-iron cylinders and an intercooler, oil-lubricated, each with an oil sight glass; V-belt drive turning them at 1,400 rpm under sheet-metal belt guards
- two three-phase 5.5 kW (7.5 hp) electric motors, 400 V / 50 Hz, thermal overload protection; the second motor starts after a delay
- air intake 2 × 827 = 1,654 l/min, pressure 11 bar, aftercooler on the outlet of each pump unit
- shared pressure switch with a gauge and a timer relay — the pump units cut in according to the air consumption, while one is being serviced the other runs
- horizontal 900 l tank on feet with holes for bolting down, safety valve, condensate valve in the bottom; air outlet through a ball valve into the pipework (regulator, filter and quick couplings at the workstation)
- noise 100 dB Lwa, 80 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 B60-2x5.5-900FT is not the right fit
On a 500 we carry the same pair of B60 pump units as the B60-2x5.5-500FT; if you want more air on a 900, reach for the B70 pump units with 7.5 kW of the B70-2x7.5-900FT. The 900-litre machines of all brands are grouped together among compressors with a 900 l tank; how the cut-in and cut-out pressure of the shared switch is set is explained in our guide to pressure switches.
Values apply to a 50 Hz supply. Air intake is the sum of the air drawn in by both pump units; how much of it reaches the tool depends on the pressure and the tank. Motor power is the sum of both motors. 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
For a production shop with pipework across the hall: the 900 holds a reserve between peaks, and the two B60 pump units start less often and run longer.

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.
