For many industry professionals, the piston air compressor has historically been the compressor of choice due to their rugged, tough and durable characteristics. Today, Atlas Copco Compressors is further building on the piston compressor’s strong reputation by announcing the release of a new line of compressors featuring full cast-iron designs.

Atlas Copco CR

The CR Range is newly engineered to be more robust and dependable.

The CR Range offers a variety of customization options including auto drain, after cooler, low oil level switch, TEFC motor, NEMA4 control panel, pressure-lubricated pump, and simplex and duplex configurations.

“Our piston compressor lines have been a consistent and reliable product over the years, and we are thrilled to take that product to the next level by offering a line with all cast iron pistons,” said Ryan Wilburn, product marketing manager for piston compressors at Atlas Copco Compressors. “With cast iron construction and industrial class bearings, our CR Range guarantees longevity and durability, even in the most demanding environments.”
