With this position paper, Eurovent supports the derogation request submitted by a coalition of leading filtration and separation media manufacturers (submission number 3014) for filtration and separation media used in high performance air and liquid applications that require a combination of water- and oil-repellence. Providing the effective and energy-efficient filtration is essential for the HVAC industry. A number of Ecodesign requirements for HVAC products can only be met due to the use of low pressure drop air filters. In the opinion of Eurovent members, the proposal to restrict C6 chemistry under the REACH Regulation poses a threat to accessing filtration products of required properties.
