Angle compressor

Comptrade CTP-S-550E3

This offer concerns a beautiful Comptrade CTP-S-550E3 diving compressor. The compressor comes with an external filling panel for diving cylinders (5 x 300 bar and 1 x 200 bar). The lever valves were replaced in 2025/2026. I am also including a 50-liter air cylinder.
This is a great set, practically ready to use. You just need to connect the electrical wires to the filling panel, and you can start working immediately!!!
PERFORMANCE: 550 liters/min
Engine speed: 1250 rpm
Dimensions: 136/80 cm (width/depth), 180 cm (height)
Weight: 450 kg
Rated power: 11 kW
RUNNING HOURS: Only 1158 hours
I have my own transport available. Price from 96-100 EUR, starting from Skierniewice, Poland, to your location, plus 0.33 EUR per kilometer one way.
