Large low speed airend, ( not high speed encapsulated airends used by others, this is much cheaper way, short life)

Premium efficiency 3 phase Motors are Totally enclosed fan cooled (Not open motor used by others, short life cheaper way)

Reduced voltage start no huge power spikes on startup (Not across the line like others building cheaper unit)

Large drop in air oil separator for long life less maintenance cost ( not small spin on separators used by others cheaper way short life )

Separate oil sump for the large oil capacity

All air and oil lines are stainless steel/ coated steel  (not hose, used by others, cheaper up front, costly to replace. Hose will fail and leak)

Microprocessor digital control monitors with safety shut down, Phase monitor, Motor amps, Air pressure, Temperature, Maintenance log

Large oil capacity  / Oil coolant this is use cool and lubricate the machine

Huge oil and *** aftercooler cooling package some of these coolers used are over twice the size used by others in the industry , many do not even use an after cooler.

Belt drive 20 hp. uses 3 belts for long belt life
