MTO II (PureAir) Series Oil-Less Reciprocating Air Compressor Systems

The MTO II (PureAir) Series is engineered for environments that require completely oil-less compressed air along with long-term mechanical durability. With no lubrication inside the compression chamber, the system eliminates the possibility of oil carryover, making it suitable for laboratories, medical facilities, food and beverage operations, electronics production, and other applications where air purity cannot be compromised. The oil-less design also reduces routine maintenance, as there is no oil to change, monitor, or dispose of. To withstand demanding duty cycles, the MTO II incorporates chrome-plated cast-iron cylinders, PTFE guide rings, sealed bearings, and a ductile iron crankshaft. Stainless steel valve cages with bronze seats help maintain consistent performance over time, while a high-capacity aluminum cooling fan manages heat during extended operation. These components allow the compressor to operate continuously or intermittently with minimal wear. By combining clean-air production with rugged construction, the MTO II offers a dependable solution for facilities that need stable air quality and reduced maintenance needs. Ontario Compressor Supplies provides the MTO II Series regionally across Southwestern Ontario with support, parts, and application guidance.
