Cowl 75: Rain cowl for a VILPE pipe with external dimensions Ø 75 mm (uninsulated Ø 75 mm pipe). AP FLOW Cowl 160: FLOW cowl for VILPE 160P/500 ventilation pipe with external dimensions Ø 160 mm. FLOW Cowl 110: FLOW cowl for VILPE ventilation pipe with external dimensions Ø 110 mm. FLOW Cowl 160: FLOW cowl for VILPE ventilation pipe with external dimensions Ø 160 mm (i.e. insulated pipe for duct sizes Ø 110 or Ø 125 mm). The cowl serves as a radon ventilator when attached to a Ø 110 insulated pipe. The cowls in the FLOW series exhibit a pressure loss reduction of up to 40% compared to earlier models, leading to savings in both ventilation energy consumption and overall living costs. When used in conjunction with the VILPE Intake solution, FLOW products can reduce the electricity consumption of ventilation units by up to 12% compared to other previous-generation products available on the market. This reduction in electricity usage translates into direct annual financial savings and contributes to environmental conservation. Thanks to intensive airflow testing and refined design, FLOW products feature uniquely effective water separation and an upward-directed airflow. This ensures even better prevention of moisture entering and allows dirty air to be expelled directly upwards, preventing particles from soiling the roof or facade. The modern design language of the VILPE Flow product range was developed in collaboration with industrial designers. The sleek, streamlined design will be applied across the entire range of cowls for roof fans, as well as for ventilation and exhaust pipes. This EPD consists of the properties of cowls of different sizes.
