The \u003cstrong\u003eshaped cowl hood\u003c\/strong\u003e deflects rain and wind away from the duct aperture, while the \u003cstrong\u003eintegrated backdraught damper\u003c\/strong\u003e closes automatically when the fan is off, preventing cold air, moisture and insects from entering the duct run. Available in \u003cstrong\u003ewhite\u003c\/strong\u003e, it suits rendered, masonry, weatherboard and UPVC cladded external walls. The round spigot connects directly to rigid or flexible 100mm duct by \u003cstrong\u003emale connection\u003c\/strong\u003e, and the 155×155mm face plate provides a neat, professional finish on the external wall surface.\u003c\/p\u003e\n\u003c!-- STAT STRIP --\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; gap: 8px; margin: 20px 0;\"\u003e\n\u003cdiv style=\"background: #008377; color: #fff; padding: 12px 16px; border-radius: 6px; flex: 1; min-width: 120px; text-align: center;\"\u003e\n\u003cstrong style=\"font-size: 18px;\"\u003e100mm\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 12px;\"\u003eDuct connection\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #008377; color: #fff; padding: 12px 16px; border-radius: 6px; flex: 1; min-width: 120px; text-align: center;\"\u003e\n\u003cstrong style=\"font-size: 18px;\"\u003e155×155mm\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 12px;\"\u003eFace plate\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #008377; color: #fff; padding: 12px 16px; border-radius: 6px; flex: 1; min-width: 120px; text-align: center;\"\u003e\n\u003cstrong style=\"font-size: 18px;\"\u003eCowled Hood\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 12px;\"\u003eRain protection\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #008377; color: #fff; padding: 12px 16px; border-radius: 6px; flex: 1; min-width: 120px; text-align: center;\"\u003e\n\u003cstrong style=\"font-size: 18px;\"\u003eDamper\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 12px;\"\u003eBackdraught shutter\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #008377; color: #fff; padding: 12px 16px; border-radius: 6px; flex: 1; min-width: 120px; text-align: center;\"\u003e\n\u003cstrong style=\"font-size: 18px;\"\u003eEasiPipe\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 12px;\"\u003eSystem compatible\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- CALLOUTS --\u003e\n\u003cdiv style=\"background: #d4edda; border-left: 4px solid #008377; padding: 12px 16px; border-radius: 4px; margin: 12px 0;\"\u003e\n\u003cstrong\u003eEasiPipe 100 System Compatible:\u003c\/strong\u003e The 4902W is part of the \u003cstrong\u003eDomus EasiPipe 100 modular round duct range\u003c\/strong\u003e, which uses consistent 100mm male\/female connections throughout — straight sections, bends, tees and all grilles connect without adaptors.
