Product detailed description
ABAC Tech ATH · 20 bar · 402 l/minATH-5,5/20-BTX delivers 402 l/min at a full 20 bar from 570 l/min of intake. It is a two-stage unit on a steel support frame with an S1 motor for continuous operation and star-delta starting. It has no air receiver — it is designed to work with a distribution network or your own certified air receiver.
Frame, or air receiver?
This machine exists in two versions with the same unit: on a frame (101 kg) and mounted on a 270-litre air receiver (211 kg). Inside it's the same thing, the only difference is whether you provide the air supply yourself or it arrives with the tank.
The frame version makes sense when you already have a main air receiver in your plant room or a long distribution line that holds the air supply on its own. It is 110 kg lighter and takes up significantly less space — 1,073 mm in length compared to 1,915 mm for the assembly on the tank.
Equipment and details

- intake 570 l/min, output 402 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 101 kg, dimensions 1,073 × 693 × 761 mm; noise level 100 dB Lwa, at 4 m 80 dB
- 2-year warranty
Machine details


Where to go next if the ATH-5,5/20-BTX doesn't fit
On the air receiver, the same machine is the ATH-5,5/20-270FTX. Smaller is the ATH-4/20-BTX, stronger is the ATH-7,5/20-BTX. The full overview is in the overview of the whole category.
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.
Ventilek advises
Without an air receiver, the machine won't hold pressure on its own — it needs somewhere to store the air. If you don't already have a twenty-bar air receiver, go straight for the version with the air receiver.
