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 reciprocating-compressor information lists capacities from approximately 3 to 95 ACFM and pressure capabilities from 20 to 500 psig on selected configurations.
Full-Pressure Lubrication
The compressor 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 manage friction, heat and component wear.
The system includes a manually reversible oil pump. Therefore, the unit can maintain lubrication regardless of the specified crankshaft rotation direction.

- Cast-iron cylinders and valve seats
- Comparatively slow operating speeds
- Intake unloaders
- Loadless starting
- Rebuildable components
- Low routine maintenance requirements
- Five-year limited warranty
Together, these features make the Quincy QR-25 1–25 HP suitable for facilities requiring durable, serviceable and dependable 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 service in applications where durability and reliability are 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, this construction provides the mechanical strength required for industrial compressed-air duties.
Moreover, cast iron 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 the starting load can limit mechanical and electrical stress throughout 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 Quincy QR-25 1–25 HP configuration depends on the required pressure, airflow and operating schedule.
Rebuildable Industrial Design
The QR-25 uses rebuildable components instead of treating the compressor pump as a disposable assembly.
Therefore, trained technicians can service or replace relevant wear components during the equipment’s operating life. Moreover, suitable replacement parts and lubricants support planned maintenance and long-term reliability.
Quincy QR-25 Applications in India
The reciprocating compressor range may support many applications across India, including:
- Manufacturing plants
- Automotive workshops
- Metal-fabrication facilities
- 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 range as carrying a comprehensive five-year limited warranty.
However, coverage is subject to the applicable warranty policy, registration, maintenance requirements and use of approved components or fluids. Therefore, users should verify the warranty conditions for the selected configuration.
