Description
Kaishan KRSB 25 HP 125 PSI 208V Rotary Screw Air Compressor
25 HP • 125 PSIG • 208V • 3-Phase • 108 CFM • Air-Cooled • Base Mount
The Kaishan KRSB-025A2F8S8U is a 25 HP base-mount rotary screw air compressor built for manufacturing, production, and plant air systems that need dependable compressed air in a practical, service-friendly package. This model is configured for 125 PSIG operation, 208V 3-Phase power, and delivers approximately 108 CFM for general plant air, pneumatic tools, production equipment, and facility maintenance applications.
What’s Included
- Kaishan KRSB rotary screw compressor package.
- Base-mount configuration for connection to a properly sized receiver and air treatment system.
Best Fit Applications
- Light manufacturing, maintenance departments, packaging lines, and repair facilities with steady daily air demand.
- Facilities that need more continuous-duty capability than a typical piston compressor can provide.
- Facilities that already have, or plan to add, a separate receiver tank and air treatment system.
- Applications requiring 208V 3-Phase electrical service and 125 PSIG system pressure.
Key Features
- Oil-injected, air-cooled rotary screw design for steady shop and industrial air demand.
- Belt drive package designed to provide a practical balance of performance, serviceability, and operating cost.
- Patented SKK air end with asymmetric 5/6 rotor profile for efficient compressed air output.
- Duplex SKF discharge bearings help support long airend life and quieter operation.
- UltraWeb low-restriction air intake filtration helps protect the compressor and reduce pressure drop.
- Efficient oil separation system with residual oil carryover limited to 3 ppm.
- Digital controller monitors operating conditions, service alerts, and fault protection.

Base Mount Configuration Notes
This is a base-mount compressor package, which means it does not include an integrated receiver tank or dryer. Base-mount units are a good fit when the facility already has properly sized air storage and treatment equipment, or when the system layout requires separate components. If you need a more compact all-in-one setup, a tank-mount or dryer-package configuration may be a better fit.
What To Verify Before Ordering
- Confirm your facility has 208V 3-Phase power available at the installation location.
- Make sure your required airflow does not exceed the compressor’s 108 CFM output.
- Check whether your system needs a receiver tank, refrigerated dryer, filters, or drain valves.
- Verify available floor space, ventilation clearance, and service access around the compressor.
- Confirm the compressor pressure rating matches your plant air requirements.
Maintenance Planning
As an oil-injected rotary screw compressor, this unit should be maintained with routine oil changes, oil filter replacement, separator service, intake filter replacement, belt inspection where applicable, and cooler cleaning. Proper downstream drying and filtration can help protect equipment, reduce moisture issues, and improve overall compressed air system reliability.
Frequently Asked Questions
Is this compressor a good replacement for a piston compressor?
Yes, this rotary screw compressor can be a good step up from a piston compressor when the application needs steadier airflow, quieter operation, and better continuous-duty performance. Confirm airflow demand, voltage, and system pressure before replacing an existing unit.
Does this compressor include a tank or dryer?
No. This is a base-mount compressor package. It is intended to connect to a properly sized receiver tank and air treatment system. If you need an integrated tank or dryer, compare this model with tank-mount or dryer-package configurations.
What electrical service is required?
This model is configured for 208V 3-Phase power. Always verify the compressor nameplate and have a qualified electrician confirm wiring, disconnects, and overcurrent protection requirements.
What accessories may be needed with this compressor?
Common supporting equipment may include a receiver tank, refrigerated air dryer, particulate and coalescing filters, automatic drains, compressor oil, and routine maintenance kits.
Can Industrial Air Power help confirm the correct Kaishan compressor?
Yes. Industrial Air Power can help review horsepower, pressure, voltage, available space, tank size, dryer requirements, and application needs before you order.
