MCH36D Kubota Diesel Compressor with Storage
Mounted to a four tank heavy-duty steel storage rack with a choice of air or nitrogen high-pressure storage cylinders, Nuvair’s flagship commercial grade compressor—the continuous-duty Coltri MCH36 pumping unit—delivers up to 27 SCFM at 6000 psi. The Coltri compressor block and Kubota diesel engine are mounted on a vibration-isolated steel base frame that is placed into a powder-coated steel crash frame with belt guard. The four tanks are split into two banks by a stainless steel distribution panel equipped with a high-pressure / high-pressure regulator for controlled pressure filling. The four-tank storage rack offers a combined storage capacity of up to 2042 cu ft (58 m³) of air.
