THE FRONT BOOT ADVANCED DUST REDUCTION SYSTEM According to Dometic, computer airflow simulation was used to design separate air-paths for pressurisation and ventilation. Hundreds of airflow simulations were required to fine-tune the system and determine the optimum intake and opening sizes. Dometic has conducted real-world testing of the DRS “in the most extreme conditions in various weather conditions with several different caravans and towing vehicles”. “The most challenging conditions involved a convoy of vehicles with the trailing vehicles entering the dust trail of the leading vehicles.” This field performance testing was validated using multiple dust sensors. “The results showed a 97 per cent reduction in dust ingress.” The Dometic DRS fits roof openings between 280x280mm and 400x400mm and roof thicknesses between 30mm and 65mm. It weighs about 3.5kg and has an RRP of $699. MORE INFO DOMETIC DUST REDUCTION SYSTEM www.dometic.com The DRS replaceable filter / 61
