Compressor Pump – Heavy-Duty, Low RPM, 100% Cast Iron

The EMAX pump is the core of the machine, engineered for maximum endurance and efficiency.

100% Cast-Iron Construction

• Solid cast-iron crankcase for stability and perfect crankshaft alignment under heavy load.

• Removable solid cast-iron cylinders for long-term durability; built to withstand heat and industrial workloads.

• Cast-iron cylinder heads for reliable cooling and long-lasting performance.

Internal Components and Build Quality

• Precision-balanced cast-iron crankshaft with Timken-style stainless steel roller bearings on both ends.

• All-steel connecting rods with replaceable bearing inserts (competitors commonly use non-repairable aluminum rods).

• Precision-machined pistons for minimal oil carryover.

• Non-absorbent premium gaskets to prevent oil seepage.

• Heavy cast-iron flywheel with built-in fan for enhanced cooling and smoother compression cycles.

Valve System and Cooling

• Long-lasting disc-style intake and exhaust valves (far more durable and serviceable than reed valves).

• Built-in intercooler and aftercooler to reduce air temperature between and after stages.

• All-copper main feed line for improved air quality and heat stability.

Low-RPM Performance Advantage

EMAX intentionally oversizes its pumps and runs them at lower RPM than most manufacturers.
Benefits include:

• Lower heat

• Reduced friction

• Higher efficiency

• Longer service life

• High CFM output thanks to larger bore and stroke

Name-Brand Electric Motor – 1750 RPM

This unit uses a top-quality OPD (Open Drip Proof) electric motor that includes a 5-year warranty and operates at 1750 RPM, unlike many competitors’ 3450 RPM motors.

Advantages of Low-RPM Motors

• Runs cooler

• Provides higher torque during startup

• Lower harmonic distortion

• Uses less electricity during startup

• Increased motor longevity

Motor Features

• Large 1-3/8" output shaft

• High-quality ball bearings (front and rear)

• Oversized starting and running capacitors

• Dynamically balanced armature for low vibration

• 1.15 service factor for up to 15% overload capacity

Belt Guard – Heavy-Duty Steel, OSHA Approved

Built in the USA from 13-gauge steel and premium expanded metal, EMAX belt guards are designed for maximum durability and safety. All belt guards meet OSHA safety standards.

Condor Switch

Prewired Condor starter and pressure switch combined into one unit.
Features an actuation-type diaphragm for reliable pressure control.

Air Tank – ASME Certified

The 80-gallon vertical tank is manufactured in the USA and fully ASME code compliant in all 50 states, including California. Built for safety, stability, and long-term use.

Controls and Components – Premium Quality

• Adjustable, top-quality pressure switch

• 100% brass check valves with Teflon seating for quieter operation

• 100% brass ASME safety valves, factory-preset and sealed

• High-quality plumbing fittings for strong, leak-free connections

• Premium brass ball valves

• Extended front-mounted water drain with ¼" ball valve for easy tank draining

• Load-less starting system thanks to built-in head unloaders, preventing motor damage during startup

Motor Pulleys and Belts

• Taper-lock, dual-groove pulleys for a secure, vibration-free fit

• Dual B-style belts for:

  • smoother and quieter performance

  • longer belt life

  • reduced load on motor and pump bearings

• Better reliability than single-groove pulley systems

Warranty

• 1-Year Standard Warranty

• 5-Year Extended Warranty

• Lifetime Extended Warranty (per EMAX conditions)
