Tank Mount Configuration Notes
This tank-mount compressor package includes receiver storage in a compact footprint. Add a refrigerated dryer, filters, and automatic drains if the application needs cleaner, drier air.
What To Verify Before Ordering
- Confirm your facility has 460V 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?
This configuration includes a receiver-mounted tank, but not an integrated dryer.
What electrical service is required?
This model is configured for 460V 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.
