Designed for rental applications, Doosan Infracore's Ingersoll Rand NHP1500 oil-free air compressors meet or exceed quality air requirements for clean air environments. It delivers 1,500 cfm of continuous air at 60 to 150 psi. The company says it operates efficiently by eliminating the need to reduce flow as the pressure is increased. The unit can run continuously at full load for 10 hours with the onboard fuel tanks or it can connect to an external fuel tank for extended use.
