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.

FILLING PANEL WITH SIX OUTLETS (5 x 300 OR 1 x 200 BAR)
AUTOMATIC SHUT-OFF SYSTEM (AUTO-STOP)
AUTOMATIC CONDENSATE DRAIN SYSTEM
removal of condensate from all interstage separators and the final separator during compressor operation
integrated pressure relief starting system (automatic drain upon each device shutdown)
condensate tank with a capacity of approximately 5 liters
noise dampers, timer to optimize the frequency of condensate draining

FILTRATION SYSTEM F 2400
transparent COMP TRADE filter cartridge with extended life and saturation indicator; three-stage filtration (drying, neutralization, microfiltration)
air quality in accordance with DIN 3188 / EN 12021: 2014 standards
filling: MS-AC-MS (ensures air quality in accordance with DIN 3188 / EN 12021: 2014)
