4 Inch Ventilation Extractor Exhaust Fan Wall Window

This 4-inch wall & window mounted extractor exhaust fan is a cost-effective ventilation blower built to solve damp, odour and air stagnation issues in small household spaces. Designed with a universal 4-inch standard size, it supports two installation modes: recessed wall mounting or direct window fitting, adapting to different room renovation layouts. Equipped with a high-performance pure copper motor, the fan creates powerful steady airflow that quickly exhausts bathroom shower steam, kitchen cooking smoke, toilet odours and musty storage room air, greatly reducing the chance of black mould, peeling paint and foggy mirrors caused by trapped moisture. The sealed waterproof casing provides reliable protection against water splashes and kitchen oil splatters, fully meeting safety requirements for humid indoor environments. Optimised fan blade and motor structure cut down operating noise, so it wont create disruptive loud hum during morning showers or late-night cooking. | FLAVORA 4 Inch Ventilation Extractor Exhaust Fan Wall Window in White
