Product Description
Quincy QR-25 1–25 HP
The Quincy QR-25 1–25 HP is a heavy-duty reciprocating air-compressor range developed for demanding industrial compressed-air applications. Moreover, its proven pressure-lubricated construction supports reliable operation, long equipment life and straightforward maintenance.
The range includes single-stage and two-stage configurations with power ratings from 1 to 25 hp. Quincy’s current reciprocating-compressor overview lists capacities from approximately 3 to 95 ACFM and pressure capabilities from 20 to 500 psig on selected configurations.
Full-Pressure Lubrication
The Quincy QR-25 1–25 HP uses a pressure-lubrication system to deliver oil to critical internal components.
Consequently, bearings, connecting rods and other moving parts receive controlled lubrication during operation. Moreover, effective lubrication helps control friction, heat and component wear.
The system includes a manually reversible oil pump. Therefore, the compressor can maintain lubrication regardless of the specified crankshaft rotation direction.

Together, these features make the Quincy QR-25 1–25 HP suitable for industrial facilities requiring durable and serviceable compressed-air equipment.
Slow-Speed Compressor Operation
The QR-25 operates at comparatively lower speeds than many lighter-duty reciprocating compressors.
As a result, internal components complete fewer operating cycles over a given period. Moreover, slower speeds may reduce heat generation, vibration and mechanical wear when the compressor is correctly installed and maintained.
Therefore, the design supports long-term operation in demanding applications where reliability is more important than compact, high-speed construction.
Heavy-Duty Cast-Iron Construction
The compressor uses cast iron in its cylinders, valve seats and other principal components. Consequently, the Quincy QR-25 1–25 HP provides the mechanical strength required for industrial compressed-air service.
Moreover, cast-iron construction supports dimensional stability under repeated compression cycles. As a result, the compressor can provide dependable performance during long operating periods.
Intake Unloaders and Loadless Starting
Intake unloaders reduce the work required during unloaded operation. Meanwhile, loadless starting reduces the compression load placed on the motor during startup.
Consequently, the motor can accelerate more easily before the compressor begins producing full pressure. Moreover, reducing starting load can limit mechanical and electrical stress on the system.
Single-Stage and Two-Stage Options
Single-stage compressors complete compression in one cylinder stage. Therefore, they suit moderate-pressure compressed-air applications.
In contrast, two-stage compressors pass the air through an intercooling and secondary compression process. As a result, they can provide higher discharge pressures and improved performance for demanding industrial duties.
However, the correct configuration depends on the required pressure, airflow and operating schedule.
Rebuildable Industrial Design
The Quincy QR-25 1–25 HP uses rebuildable components rather than treating the compressor pump as a disposable assembly.
Therefore, trained technicians can service or replace relevant wear components during the compressor’s operating life. Moreover, genuine Quincy replacement parts and lubricants support planned maintenance and long-term reliability.
Applications in the UAE
The Quincy QR-25 may support:
- Manufacturing plants
- Automotive workshops
- Metal fabrication
- Oil and gas support operations
- Industrial maintenance facilities
- Pneumatic tools
- Sandblasting equipment
- Agricultural facilities
- Packaging machinery
- Service stations
- Construction workshops
- High-pressure industrial processes
For example, a workshop can use a standard-pressure two-stage package for pneumatic tools. Alternatively, a specialised QR-25 configuration can support applications requiring higher compressed-air pressure.
Selecting the Correct QR-25 Compressor
Correct selection depends on:
- Required airflow
- Required operating pressure
- Motor horsepower
- Single-stage or two-stage compression
- Daily operating hours
- Electrical supply
- Receiver size
- Cooling and ventilation
- Installation environment
- Future compressed-air demand
Therefore, users should calculate the actual air demand and required pressure before selecting the compressor. Otherwise, an undersized unit may run continuously, while an oversized system may cycle inefficiently.
Warranty Coverage
Quincy identifies the QR-25 as carrying a comprehensive five-year limited warranty. However, coverage is subject to the applicable warranty policy, registration, maintenance requirements and use of approved parts or fluids.
