The high efficiency carbon filter is capable of removing oil vapour and odour from compressed air. The activated carbon towers will, by the use of adsorption, reduce the residual oil content to lower than 0.003 mg/m³ at 35°C and 7 bar inlet pressure. The pressure drop is low and stays minimal during the lifetime of the filter. Within the specialised pharmaceutical, food and beverage, electronic and other industries where air purity is critical, there is often a requirement to remove residual oil vapours and odours from the compressed air supply
