Mattei ERC 4-5 / 504-505, ER 4-5, AC 4-5 Kits

The Mattei ERC 4-5 / 504-505, ER 4-5, and AC 4-5 compressors are reliable rotary vane air compressors designed to provide consistent compressed air for small to mid-size industrial operations. Built with Mattei’s proven vane technology, these compressors operate at low rotational speeds and utilize a direct-drive design between the motor and compressor airend. This configuration reduces mechanical losses, improves energy efficiency, and minimizes wear compared to many traditional compressor designs. The ERC 504 and 505 models typically operate in the 5 HP to 7.5 HP range, producing approximately 23–33 CFM at around 125 PSI, making them ideal for automotive shops, maintenance facilities, and light manufacturing environments that require dependable compressed air.

Another advantage of the Mattei ERC, ER, and AC 4-5 compressor platforms is their focus on durability, efficiency, and simplified maintenance. These compressors feature robust open-frame or cabinet designs, high-efficiency intake filtration, and integrated aftercoolers that help deliver clean compressed air for demanding applications. Mattei’s rotary vane compression system is engineered for extremely long service life, with vanes, rotors, and stators designed to operate for 100,000+ hours with proper maintenance, significantly lowering long-term ownership costs.
