Explosion Proof Screw Air Compressor

Pairing a high-efficiency screw airend with a fully certified explosion-proof electrical package, the Comps explosion proof screw air compressor is built for hazardous industrial areas where any normal ignition source cannot be tolerated. The screw airend gives smooth, efficient, low-vibration compression with fewer wearing parts than a reciprocating machine, which makes it the right choice for continuous plant air in classified areas rather than an intermittently running unit. The electrical system, including an explosion-proof motor, explosion-proof solenoid valves and a sealed explosion-proof control box, is rated so that no ignition source can escape into flammable atmospheres. The junction box uses a flameproof sealed construction that contains any internal spark or hot surface, and the unit holds a national explosion-proof certificate. Multiple explosion-proof grades are offered so buyers can match the machine to the specific hazardous zone, gas group and temperature class rather than using a one-grade-fits-all unit. The series runs at higher pressures than a general explosion-proof air compressor, covering roughly 20.5 to 37 m3/min at 12.5-25 bar with 132 to 315 kW drives, serving oil extraction, gas processing and tank-farm air systems. For refineries and gas plants that cannot risk a shutdown in a classified area, this reliable screw core is what justifies the higher up-front certified build. The distinction is that this is a screw machine designed for efficient continuous compression at elevated pressure inside classified areas, rather than a general unit simply fitted with an explosion-proof motor.

Hazardous-area projects often buy explosion-proof screw stations as a multi-machine package for refineries, gas plants or tank farms. We offer tiered price discounts that scale with order volume, and batch orders receive priority production scheduling and shipping so a large project does not wait behind small jobs. For EPC or fleet buyers, this directly lowers cost per station and protects the project schedule for rolling deployment across multiple sites.

Applications

 

Oil extraction and gathering. Efficient screw compression at 12.5-25 bar supplies instrument and process air inside classified oilfield areas.

Natural gas processing plants. Multiple explosion-proof grades let the unit match the gas group and temperature class of the gas-handling area.

Underground coal mines and tank farms. The sealed electrical package prevents ignition in methane or hydrocarbon-vapor atmospheres.

Paint booths and solvent-based finishing. The certified screw station provides continuous clean compressed air without ignition risk.
