What our Experts Think
-
Powerful performance for tough jobs
Produces strong airflow (~25–28 CFM at 100 PSI) with stable pressure—great for running multiple pneumatic tools simultaneously without lag.
-
Two‑stage efficiency
Two‑stage compression delivers higher pressure and better thermal efficiency than single‑stage units, reducing cycling and extending component life.
-
80‑gallon tank for smoother use
Large tank capacity provides a steady air reserve, minimizing pressure fluctuations during sanding, spraying, or impact work.
-
230 V single‑phase convenience
Works with standard 230 V single‑phase power—no need for three‑phase wiring—making it easier to install in shops or garages.
-
Durable Quincy engineering
Cast‑iron pump and quality components ensure rugged reliability and long service life, even under frequent heavy use.
-
Straightforward operation and service
User‑friendly pressure switch, clear gauges, and accessible maintenance points keep daily use simple.

Maintenance Tips
-
Drain tank daily: Prevents moisture buildup and rust in the 80-gallon tank.
-
Check and change oil regularly: Keeps the two-stage pump properly lubricated for long service life (~50,000 hrs).
-
Clean or replace intake filter: Maintains steady airflow (~20 CFM) and protects pump components.
-
Inspect belts & alignment: Ensures efficient power transfer from the 7.5 HP motor.
-
Clean intercooler & cooling fins: Optimizes heat dissipation during continuous operation.
-
Test safety valves & pressure switch: Maintain safe operation up to 175 PSI.
-
Check for leaks & tighten fittings: Prevents air loss and maintains consistent pressure.
-
Inspect electrical connections: Verify 230V 1-phase wiring and motor protection.
-
Examine tank & components: Watch for rust, wear, or corrosion to extend lifespan.
