Neutralox utilises the process of photoionisation to remove odour UVC light is used to break down the molecular links of odorous compounds.

• Each unit consists of a stainless steel housing which contains banks of UV lamps and carbon catalyst. There is usually an integrated fan to keep everything under negative pressure.

• Untreated air first passes through a dust filter, then the UV compartment where UV light initiates photocatalytic reactions. Strong oxidants like oxygen radicals and hydroxyl radicals (O-2, OH-, O3, etc.) are produced.

• Air then passes through the catalyst section. The carbon catalyst provides further degradation of odorous compounds and prevents the release of oxidants. While some of the contaminants are oxidised immediately in the UV chamber others are adsorbed to the surface of the catalyst and are subsequently degraded through the interaction of catalyst, oxidants and UV light.

• Treated air is normally discharged to atmosphere via a small stack.
