The Air-Cooled, Pressure-Lubricated, Reciprocating HDI Series Duplex – 5 to 15 HP is Engineered to Provide a Heavy-Duty, Durable and Dependable Air Compressor Built to Withstand the Most Demanding Industrial Environments.
Duplex Units are equipped with 2-Stage, 2-Cylinder (247) or 4-Cylinder (447) Cast-Iron Compressor Pumps, 2 ODP motors, and 2 optional Magnetic Starters with an Alternator Relay, or an optional Alternating Control Panel (ACP) providing Reliable, Continuous-Use, 24/7 Operation.
The Heavily Weighted Cast Iron Pumps and Low RPM enhance heat dissipation and enable up to a 75-80% duty cycle. DV’s proprietary pressure lubrication process ensures oil is delivered to journal bearings and all necessary components, minimizing oil carry-over and friction.
The moving components of these pumps are machined, honed, balanced and assembled in Canada. Rugged construction and long life allows DV Systems to confidently offer an unprecedented 7 Year Warranty for the HDI Series.
