• Direct drive, non-geared, C-flange mounted airend.
• Modulating, vertical inlet valve.
• Heavy-duty, 5 micron, dry canister-type, inlet air filter.
• 230 or 460/3/60 1.15 SF, ODP, EPAct "energy efficient" drive motor. 1800 or 3600 RPM.
• Airend and motor shaft are coupled through a permanently aligned, resilient, cushion-type, flexible coupling.
• Stainless steel control lines.
• Unitized airend/motor assembly mounted to the compressor base with all angle elastomer vibration isolators.
• ASME coded air/oil reservoir with Eliminator separator element.
• Air or Water cooled Oil cooler/aftercooler.
  - Air cooled models have a heavy duty radiator type heat exchanger with a thermally controlled, totally enclosed fan motor.
  - Water cooled models have a shell and tube type heat exchanger.
• Themostatic oil mixing valve.
• Package mounted moisture separator and trap.
• Rigid steel base with fork lift slots.
• Pressure relief valve and discharge check valve.
• Automatic blowdown valve through inlet filter.
• Minimum discharge pressure valve.
• Lube system includes all galvanized steel fittings and piping.
• Factory fill with AEON 9000 Rotary Screw Lubricant.
• Modulating capacity control system with automatic "low demand" mode reservoir blowdown.
• Auto Sentry "ES+"microprocessor based, fully programmable, touch pad controller with the following functions:
  - Full text vacuum florescent display (VFD) with interactive compressor diagram.
  - Operating mode selection: constant run, low demand with reservoir blowdown, automatic stop/start with timed blowdown and sequenc (up to 8 units), all with modulating inlet valve or load/no lode control.
  - Emergency stop button.
  - Power interruption protection.
  - High speed electronic modulation control
  - Thermally controlled fan motor on air cooled units.
  - Contacts for remote start/stop operation plus remote monitoring
  - Complete system diagnostics through VFD.
  • Displays for hourmeter, loaded hours, total run time, discharge air temperature, system/reservoir pressure, separator differential pressure and motor amps.
  • VFD advisory lamps, light yellow on diagram, displays service for air filter, change separator, oil and oil filter change, high/low temperature, sequencing communication error, and high motor amps.
• VFD protective shut down lamps, light red on diagram, displays high temperature, low oil pressure, main motor overload, fan motor overload, high pressure, change separator, choice of one field-selectable message: High vibration, phase relay, motor protector, low voltage.
  
  
• Optional Equipment:
• Wye delta main motor and starter - IEC rated.
• NEMA 4 (IP-66) control enclosure.
• TEFC and premium efficiency main motor.
