This product features a removable cowl section that simplifies installation and cleaning. Its white color adds a clean look to any space. The cowl serves as a barrier, shielding your property from rain and wind that might otherwise enter through the duct. Additionally, it includes a built-in anti-backdraft shutter blade, which can be easily removed if not needed. Ideal for use with cooker hoods, bathroom, toilet, kitchen ventilation fans, and tumble dryer extractors.
