Product Information
Full details
The Nuair NB2800B-Pro is a robust, belt-driven air compressor designed for workshop environments. It offers reliable performance with a focus on reduced noise levels thanks to its low-speed operation and advanced cooling system. While it delivers consistent air supply for various applications, users should be aware of its 400V power requirement and the need for proper oil maintenance typical of lubricated compressors.

FAQs
What type of oil should I use for the NB2800B-Pro?
Consult the product manual for the specific type and viscosity of compressor oil recommended. Typically, high-quality air compressor oil is required.
How often should I check the oil level?
It is recommended to check the oil level before each use or at least daily during operation. Refer to the user manual for detailed intervals.
Can this compressor be used for spray painting?
Yes, but it is highly recommended to use an air preparation unit (filter, regulator, water separator) to ensure clean, dry air for optimal paint finish.
What is the warranty period for the pump?
The Nuair NB2800B-Pro comes with a two-year warranty on the pump, subject to terms and conditions, which typically involve correct installation and maintenance.
Is this compressor oil-free?
No, the NB2800B-Pro is a lubricated compressor, meaning it uses oil for lubrication of the pump mechanism.
What is the maximum operating pressure?
The compressor can operate up to a maximum pressure of 10 Bar (approximately 145 psi).
Do I need a special electrical setup for this compressor?
Yes, this compressor requires a 400V, 3-phase electrical supply. Ensure your power source meets this requirement.
Troubleshooting
Compressor not starting
Check the 400V power supply connection. Ensure the motor overload protection has not tripped; if so, allow it to cool and reset. Verify the pressure switch is functioning correctly.
Low air pressure output
Check for air leaks in hoses or connections. Ensure the intake filter is clean. Verify the pressure setting on the regulator. Check the oil level; low oil can affect pump performance.
Excessive noise
Ensure drive belts are correctly tensioned and in good condition. Check that all mounting bolts are tight. Inspect the pump for any internal issues if the noise is unusual or grinding.
Compressor cycles on and off too frequently
Check for air leaks. Ensure the air receiver is not leaking. The demand for air may be exceeding the compressor's capacity, or the pressure switch might be set incorrectly.
Moisture in the air line
Drain the air receiver daily. Ensure the after-cooler is functioning correctly. Use an appropriate air dryer or filter system for applications sensitive to moisture.
Pros and Cons
Pros
- Significantly reduced noise levels compared to direct-drive models.
- Efficient operation due to advanced cooling and belt-drive design.
- Durable construction suitable for regular workshop use.
- Large air receiver capacity for sustained tool operation.
- Includes overload protection for the electric motor.
Cons
- Requires a 400V power supply, limiting its use in some locations.
- As a lubricated compressor, it requires regular oil checks and maintenance.
- Larger and heavier than smaller, direct-drive units.
- Lower noise level is relative; it's still an industrial-grade compressor.
Setup, Compatibility & Care
Setup:
- Ensure the compressor is placed on a stable, level surface with adequate ventilation.
- Connect the compressor to a suitable 400V, 3-phase power outlet.
- Verify the air outlet hose is securely connected and rated for the required pressure.
- Check the oil level in the crankcase before the first use and maintain it as per the manufacturer's recommendations.
Compatibility:
- Power: Requires a 400V, 1/50Hz, 3-phase electrical supply. Ensure your electrical system can support the 2.2kW motor.
- Air Tools: Compatible with standard pneumatic tools requiring pressures up to 10 Bar (145 psi). Consider an air preparation unit (filter, regulator, lubricator) for critical applications like spray painting.
Care:
- Oil: Regularly check and top up the compressor oil. Change the oil according to the maintenance schedule outlined in the user manual.
- Drain Valve: Drain the air receiver regularly to remove accumulated moisture and prevent corrosion.
- Filters: Clean or replace air intake filters as recommended to ensure optimal performance and prevent dust ingress.
- Belts: Periodically inspect the drive belt tension and condition, adjusting or replacing as necessary.
- Cleaning: Keep the compressor exterior clean and ensure cooling vents are free from obstructions.
