EK76-Q325D Kubota Diesel LP Nitrox Surface Supply System
The EK76-Q325D low pressure (LP) nitrox production system is a self-contained and portable delivery package capable of supplying air or enriched air nitrox up to 40% (EANx40) to surface supply divers. The turnkey system utilizes two low pressure compressors mounted together with a 37.4 hp (28 kW) Kubota diesel engine along with a permeable membrane system in a powder-coated steel frame. The system components include: back-pressure regulator, low pressure air filtration, gas stream temperature stabilizer (heater), permeable membrane, mixing tube, air intake filter, inline sensor/oxygen analyzer, compressor intake porting and two LP compressors. All of the component assemblies and parts are mounted to facilitate easy setup, operation, and transport.
