What our Experts Think

• Balanced power for serious shop work
  With ~18–20 CFM at 100 PSI and up to ~175 PSI, this 5 HP two‑stage compressor handles multiple air tools smoothly without pressure lag—ideal for automotive and woodworking tasks.
• Two‑stage efficiency for consistency
  The two‑stage pump delivers higher pressure and better efficiency than single‑stage units, meaning less cycling and more usable air per tank fill.
• 80‑gallon tank = steady supply
  Larger tank capacity reduces compressor cycling and maintains consistent pressure during prolonged use—great for spray guns, sanders, and grinders.
• 1‑Phase 230 V convenience
  Runs on standard 230 V single‑phase power—no need for three‑phase wiring—making it easier to install in shops and garages.
• Pro Plus features for durability
  Includes enhancements like automatic drains and low‑oil shutoff to protect the pump and reduce maintenance downtime.
• Reliable build quality
  Quincy’s robust cast‑iron pump and proven engineering deliver long service life and quiet, cooler operation compared with many competitors.

Maintenance Tips

• Drain tank daily: Prevent moisture buildup and internal rust in the 80-gallon tank.
• Check and change oil regularly: Maintain proper lubrication for splash-lubricated two-stage pump; promotes long life (~50,000 hrs).
• Clean or replace intake filter: Ensures steady ~15 CFM output at 175 PSI and protects pump components.
• Inspect belts & alignment: Prevent slippage and maintain efficient power transfer from the 5 HP motor.
• Check intercooler & cooling fins: Keep free of dust/debris to optimize heat dissipation.
• Test safety valves & pressure switch: Verify operation for safe pressure range up to 175 PSI.
• Tighten fittings & check for leaks: Prevent air loss and maintain consistent pressure.
• Monitor electrical connections: Ensure proper 230V 1-phase wiring and motor protection.
• Inspect tank & components: Look for rust, wear, or corrosion to extend service life.
