Description
Kaishan KRSD 40 HP 115 PSI 208V Rotary Screw Air Compressor
40 HP • 115 PSIG • 208V • 3-Phase • Air-Cooled • Base Mount
The Kaishan KRSD-040A1F8S8U is a 40 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 115 PSIG operation, 208V 3-Phase power for general plant air, pneumatic tools, production equipment, and facility maintenance applications.
What’s Included
- Kaishan KRSD direct drive rotary screw compressor package.
- Base-mount configuration for connection to a properly sized receiver and air treatment system.
Best Fit Applications
- Production facilities, plant air systems, and industrial users with higher sustained compressed air demand.
- Operations that need a serviceable rotary screw package for daily shop or process air.
- Facilities that already have, or plan to add, a separate receiver tank and air treatment system.
- Applications requiring 208V 3-Phase electrical service and 115 PSIG system pressure.
Key Features
- Oil-injected, air-cooled rotary screw design built for continuous-duty industrial air demand.
- 1:1 direct drive design with no gearbox to reduce transmission losses.
- Patented SKK air end with asymmetric 5/6 rotor profile for efficient compressed air output.
- Premium SKF discharge bearings support long bearing life and quieter operation.
- Three-stage tangential oil separation helps reduce pressure drop and limits residual oil carryover to 3 ppm.
- 316 stainless steel control tubing improves corrosion resistance and long-term reliability.
- Digital controller provides fault protection, service alerts, and sequencing capability.

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.
- Confirm the compressor airflow rating against your actual system demand before ordering.
- 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.
