ISOMAX ACOUSTIC DUCT FAN

Description

Isomax Acoustic Duct Fan is a noise-reduced inline centrifugal fan from Systemair, engineered specifically for grow room and indoor cultivation environments where quiet operation is as important as airflow performance. We have been recommending Isomax fans to UK growers since 2017 as one of the best solutions for achieving effective ventilation in residential growing spaces where fan noise is a consideration.

Why Acoustic Performance Matters in Grow Room Fans

Standard inline fans — even high-quality units like the RVK series — produce a characteristic motor and turbine hum that can be intrusive, particularly during overnight operation when ambient noise levels are lower. The Isomax addresses this with a dual-layer acoustic housing that absorbs and dampens both motor vibration and airflow turbulence, resulting in sound levels significantly below equivalent standard fans. Growers who have switched from conventional inline fans to the Isomax typically report a dramatic reduction in audible fan noise from adjacent rooms.

Despite its acoustic insulation, the Isomax does not compromise on airflow performance. It delivers airflow rates equivalent to standard fans of the same diameter, making it a true drop-in replacement in any existing ventilation setup. Systemair’s engineering heritage ensures reliable, consistent performance across extended operating periods.

Installation and System Compatibility

The Isomax is available in standard duct diameters (125mm, 150mm, 200mm) and uses the same connection fittings as conventional inline fans. Connect to your carbon filter on the intake side and route exhaust ducting to your extraction point using standard aluminium ducting and Fast Clamp connectors. For maximum noise reduction, use acoustic ducting on both sides of the fan and mount it on vibration-dampening brackets or suspension ropes rather than rigid fixings.

Compatible with all standard fan speed controllers for variable airflow management. Pair with a quality carbon filter, acoustic ducting and a digital fan controller for a near-silent, fully controllable grow room ventilation system.
