Description
Overview
The EMAX ESP07V120V3-208 is a Silent Air Industrial Plus 7.5 HP, 120-gallon two-stage reciprocating air compressor on 208/230V three-phase power. It delivers 31 CFM at 100 PSI from a four-cylinder cast iron pump.
The Industrial Plus build adds a TEFC motor, automatic tank drain, belt tensioner, and continuous-run capability to the pressure-lubricated pump, which suits a shop running higher duty cycles. The larger 120-gallon vertical tank cuts cycling and the pump builds to 175 PSI. The Silent Air design runs noticeably quieter than a standard open compressor, which matters when the unit sits in an occupied shop bay.
Key Features
- 31 CFM at 100 PSI - 7.5 HP four-cylinder two-stage pump output for steady air delivery.
- Two-stage pressure to 175 PSI - on an 120-gallon vertical tank that holds reserve for demand spikes.
- Pressure-lubricated pump - a gear-driven oil pump feeds each bearing for continuous-duty cooling and long pump life.
- Cast iron pump - crankcase, cylinders, and heads in cast iron for heat tolerance under load.
- 208/230V three-phase power - TEFC motor on a 40 amp recommended breaker.
- Belt tensioner and isolator pads - simplify belt service and cut transmitted vibration.

Key Facts
- Delivers 31 CFM at 100 PSI from a 7.5 HP four-cylinder two-stage pump.
- Builds to 175 PSI on an 120-gallon vertical tank.
- Cast iron pump rated for an estimated 70,000 hours with proper maintenance.
Who It's For
This compressor fits a three-phase shop running sustained air demand, such as a busy production bay or multi-station tool setup, where continuous-run operation and a TEFC motor earn their keep.
What's Included
- The compressor pump, motor, and ASME-coded air tank assembled as one unit
- Isolator pads
- Belt tensioner
- Owner and maintenance documentation
Shipping and Freight
This compressor ships LTL freight at roughly 988 lb. The 120-gallon vertical unit is tall and palletized, so plan for liftgate or forklift offload and confirm ceiling height.
About EMAX Compressor
EMAX builds compressed air equipment for automotive, industrial, and commercial shops. The reciprocating line uses all cast iron pumps with rebuildable connecting rods and disc valves chosen for long service life under demanding duty.
Frequently Asked Questions
How much air does the ESP07V120V3-208 deliver?
It is rated at 31 CFM at 100 PSI from a 7.5 HP pump, with a maximum pressure of 175 PSI. Size your tools to stay within that delivery at working pressure.
What power does it require?
It runs on 208/230V three-phase power with a recommended 40 amp breaker. Confirm your service before installation.
Is the pump pressure or splash lubricated?
This pump is pressure lubricated. A gear-driven oil pump delivers oil to the bearings and connecting rods, which suits higher duty cycles.
What maintenance does it need?
Routine care is oil changes, belt checks, and tank draining. EMAX rates the pump for an estimated 70,000 hours of service life with proper maintenance, and service kits are available.
What does continuous-run with auto drain add?
The automatic drain clears condensate without a manual valve, and continuous-run capability lets the compressor stay running under sustained demand instead of repeatedly starting and stopping, which protects the motor.
