Profile: Addvent Limited specializes in producing ventilation and fan equipment. We provide commercial and industrial ventilation products. Our re-styled industrial fan range provides cost-effective solutions for most industrial applications. These axial fans are high performance 1200- 17,050 m3/hr, low-noise fans for use in general industrial, commercial, and catering applications. Matching gravity grilles are available, and there is a range of variable-speed controllers to suit each fan. Our powerful in-duct mixed flow fan is designed to produce higher working pressures up to 360 Pa in situations where high airflow up to 910 m3/hr together with relatively low noise is required. For use with either rigid or flexible ducting, the fans can also be mounted in series for increased pressure, or in parallel for increased airflow. These fans are now available with an integrated timer on the 100 mm to 150 mm sizes.
