Product detailed description
ABAC Tech ATH · 20 bar · 906 l/minA jump into a different size class. ATH-11/20-BTX delivers 906 l/min at a full 20 bar from an intake of 1,392 l/min — compared to the seven-and-a-half, that's 360 l/min more, i.e. two-thirds more. It's a two-stage unit on a steel support frame, without a tank, with an S1-rated motor for continuous operation and star-delta starting.
What changes with size
It's not just about more air. The machine weighs 185 kg compared to 121 kg for the seven-and-a-half, it's twenty centimetres wider and taller, and noise rises to 106 dB Lwa instead of 101. The installation therefore needs to be prepared — a load-bearing floor, clearance for cooling, and a ventilated machine room.
There's only one version: on a support frame, without its own pressure vessel. At this size, it's assumed that you already have a main air receiver in the machine room — and it must be certified for twenty bar, the same as the entire distribution system.
Equipment and details
What the ATH-11/20-BTX comes with from the factory
- two-stage oil-lubricated unit with two V-shaped cylinders, 1,500 rpm
- 11 kW motor in S1 mode, i.e. 100% duty cycle without pauses for cooling
- direct drive without belts — the unit sits directly on the motor
- mounted on a steel support frame without an air receiver — air goes to the distribution network or to your own tank
- electric motor 400/50 V/Hz, three-phase supply, star-delta starting
- intake 1,392 l/min, delivery 906 l/min at an operating pressure of 20 bar
- intercooler between the low-pressure and high-pressure cylinder, stainless steel valves
- crankshaft bearings factory-filled with grease for the entire service life
- weight 185 kg, dimensions 1,073 × 820 × 840 mm; noise level 106 dB Lwa, 86 dB at 4 m
- 2-year warranty
Machine details
Where to go next if ATH-11/20-BTX isn't the right fit
The weaker option is ATH-7,5/20-BTX, and the most powerful machine in the category is ATH-15/20-BTX. Complete assemblies with an air receiver top out with the ATH-7,5/20-270FTX. The full overview is in the category overview, and five bar lower in the 15 bar series.
Delivery is the amount of air the machine delivers at an operating pressure of 20 bar; intake is the volume drawn in by the low-pressure cylinder. Noise level is given as the sound power level Lwa from the nameplate and as sound pressure at 4 m from the machine. Performance data according to ISO 1217, Annex C, noise level according to ISO 2151.
The valve advises
Eleven kilowatts at twenty bar makes the compressor a standalone technology. Before you order it, think through the power supply, protection, and heat removal from the compressor room.
