Nuair AIRSIL Model Guide
Choose the compressor around the real air demand of the equipment being supplied, the required working pressure and the expected duty cycle. Receiver capacity and enclosure format should then be considered alongside installation space and the available electrical supply.

Why Choose an AIRSIL Compressor?
Understanding the Noise Figures
The smaller AIRSIL and AIRSIL EVO models are listed at 65 dB(A), while manufacturer literature lists the larger AIRSIL2 and AIRSIL3 floor-mounted machines at 64 dB(A). Sound data should always be checked against the exact model and the manufacturer's stated test conditions.

Silenced Belt-Drive Compressor FAQs
Are all AIRSIL compressors rated at exactly 65 dB(A)?
No. Manufacturer data lists models in this range at approximately 64 to 65 dB(A), depending on the exact machine. Check the individual model specification where noise is critical.
Are both single-phase and three-phase compressors available?
Yes. The smaller 100-litre packages include 230V and 400V options. The larger AIRSIL2 and AIRSIL3 machines use a 400V three-phase supply.
What is the difference between floor-mounted and receiver-mounted models?
A floor-mounted compressor package is intended to connect to a separate receiver or compressed-air system. Receiver-mounted versions combine the compressor with an air receiver in one package.
Does a larger receiver increase compressor output?
No. A receiver stores compressed air and can help buffer short peaks in demand, but it does not increase the compressor pump's continuous capacity.
Can you help size the compressor?
Yes. Send us the equipment being supplied, required pressure, expected running pattern and available electrical supply and we can help compare suitable models.
