High-Performance Acoustic Inline Fan for Quiet, Efficient Ventilation

The Isomax Acoustic AC 150mm Inline Fan (410m³/hr) is a premium silenced ventilation fan designed for growers who require strong airflow with minimal operating noise. Built with an insulated acoustic housing and a high-quality AC motor, this fan provides reliable extraction or intake airflow while significantly reducing sound levels compared to standard inline fans.

With a 150mm (6″) duct connection and a maximum airflow capacity of 410m³ per hour, the Isomax fan is well suited for small to medium grow tents and grow rooms. The internal acoustic foam lining helps absorb vibration and fan noise, making it ideal for indoor environments where discreet operation is important.

Unlike EC fans with integrated digital control, this version is supplied without a controller, allowing growers to pair it with their preferred fan speed controller or environmental controller for adjustable airflow management.

Key Features:

• Fan Diameter: 150mm / 6″ duct compatibility

How to Use the Product & Best Usage Recommendations

Installation

The Isomax fan is designed to be installed inline with ventilation ducting. Connect the 150mm ducting to each end of the fan using duct clamps or fasteners, ensuring an airtight seal to maximise airflow efficiency. The fan can be mounted horizontally or vertically using the attached mounting brackets.

For grow room extraction systems, the fan is commonly positioned:

• Between the carbon filter and ducting, or

• After the filter to pull air through the filtration system

Using a Speed Controller

Because this version is supplied without a controller, it can be paired with most compatible AC fan speed controllers. This allows growers to reduce noise levels, control airflow, or match ventilation output to environmental conditions.

Best Usage Recommendations

• Ideal for grow tents, small grow rooms, and ventilation extraction systems

• Works efficiently with 150mm carbon filters and acoustic ducting

• Mount the fan using rubber straps or anti-vibration mounts to minimise structural noise

• Keep duct runs as straight as possible to maintain airflow efficiency

• Periodically inspect the fan and ducting for dust buildup or airflow obstruction

When combined with a carbon filter and quality ducting, the Isomax fan provides efficient air exchange and odour control while maintaining a quiet growing environment.
