The NARDI COMPRESSORI CO2 reducer is an absorption filter that can significantly reduce the concentration of carbon dioxide in compressed air. It is a fantastic accessory for breathing air recharging systems installed in locations where CO2 concentration is rather high when compared to normal standards. The filter must be positioned on the wall before the compressor intake with special fittings supplied by NARDI COMPRESSORI. It is compatible with all compressors of the NARDI COMPRESSORI range and is part of a line of accessories dedicated to ensuring the best air quality.
