The EMAX ERVK070003-460 is a 7.5 HP rotary screw air compressor built for shops and light-industrial operations that need continuous air supply for tools, plasma cutters, sandblasters, or production equipment running longer than a piston compressor can handle. The oil-injected, single-stage rotary screw air end is rated for 100% duty cycle, so it runs without forced cool-down periods, and EMAX estimates a 100,000-hour service life for the air end's male-and-female rotor design.
Key Engineering Features
Delivers 29 CFM at 100 PSI, up to 145 PSI maximum, on 460V three-phase power
Integrated 30 CFM refrigerated air dryer matched to the compressor's full output
Two-belt V-belt drive with wider B- and C-width belts for lower tension and reduced noise, with the unit measured at about 62 dB(A)
TEFC, 1750 RPM motor drawing 10.4 full-load amps (1.15 service factor), with VSD-ready motor and cabinet for an optional future variable-speed conversion
Onboard digital control panel displaying pressure and temperature, with start/stop, emergency stop, and six built-in maintenance notifications
Swing-arm dryer mount that hinges away from the cabinet for easier access to filters, belts, and the air end
Dual-timer electric automatic tank drain, adjustable from 1 to 45 minutes, with a muffler for quiet discharge
Power & Installation
This unit requires a dedicated 460V three-phase circuit and ships by freight. Confirm your shop's electrical service and freight access before ordering. Breaker and wire sizing should match the motor nameplate and local electrical code, installed by a licensed electrician.
