Quincy QT Max Air Compressor 7.5 HP 80 Gallon Two Stage Single Phase 230V New - 2020040726
The Quincy QT reciprocating piston air compressor is more than just your typical splash-lubricated two-stage. The highly efficient, robust QT delivers more air (CFM) per brake horsepower while consuming less energy. It features cast-iron where it’s needed for strength and durability, and aluminum where it’s needed for optimum cooling and long life. The "Max" configuration features automatic tank drain, low oil shutdown, and heavy-duty aftercooler included.

Maintenance Tips
-
Check Oil Level & Change Regularly
This splash-lubricated, cast-iron pump requires consistent oil checks; change oil every 3–6 months or per usage to prevent wear.
-
Drain Tank Moisture Daily (or Use Auto Drain)
The MAX series often includes an automatic tank drain, but manual checks ensure zero moisture buildup and prevent tank corrosion.
-
Clean/Replace Intake Air Filters
Maintain proper airflow to sustain high output (~22.4 CFM) and reduce strain on internal components.
-
Inspect Belts, Aftercooler & Fittings
The belt-driven, aftercooled system should be checked regularly for tension, leaks, and airflow efficiency.
-
Monitor Low Oil Safety System
MAX models include a low oil shutdown switch—test periodically to protect the pump from damage.
-
Ensure Proper Ventilation & Cooling
Low-RPM operation reduces heat, but adequate airflow is essential for continuous-duty industrial use.
-
Tighten Components & Check Vibrations
Heavy-duty operation can loosen bolts—inspect pump, tank mounts, and fittings regularly.
-
Schedule Preventive Servicing
Professional maintenance helps maintain 175 PSI performance and extends compressor lifespan.
