FAN Isomax Acoustic AC 355mm – 4800m³/hr (14″)

High-Powered Acoustic Ventilation Fan for Large Grow Rooms & Commercial Environments

The Isomax Acoustic AC Fan 355mm (14″) is a heavy-duty inline extraction fan engineered to deliver extremely high airflow while minimising operational noise. With a powerful extraction capacity of 4800m³/hr, this fan is designed for large grow rooms, commercial cultivation facilities, climate-controlled environments, and ventilation systems where maintaining strong air exchange is essential.

Unlike standard inline fans, the Isomax range features a fully insulated acoustic housing that significantly reduces motor and airflow noise. The fan casing is lined with dense acoustic foam insulation, helping dampen vibration and sound transmission through ducting systems. This makes the unit particularly suitable for growers and installers who require powerful airflow without excessive noise output.

The fan uses a reliable AC motor system, offering dependable continuous operation and compatibility with many traditional fan speed controllers and climate control systems.

Installation

The fan should be installed inline within a properly supported ducting system. Due to its size and weight, secure mounting is essential to minimise vibration and ensure safe operation. Positioning the fan after a carbon filter in extraction setups generally provides the most efficient airflow management.

For optimal acoustic performance:

• Pair with insulated acoustic ducting

• Use anti-vibration mounts or straps where possible

• Avoid sharp duct bends that may increase turbulence and noise

Ventilation Recommendations

This 4800m³/hr model is designed for:

• Large grow rooms

• Multi-light cultivation environments

• Commercial extraction systems

• High-temperature spaces requiring rapid air exchange

Correct airflow sizing depends on:

• Room volume

• Heat load from lighting and equipment

• Ducting length and resistance

• Carbon filter restrictions

Using an undersized fan can lead to heat buildup and poor humidity control, while correctly sizing extraction improves temperature stability, fresh CO₂ intake, and odour management.

Maintenance

• Periodically inspect the fan and ducting for dust buildup

• Ensure airflow paths remain unobstructed

• Check mounting points regularly in long-term installations

• Disconnect power before cleaning or servicing

The insulated casing helps maintain quieter operation over long periods, especially in environments running continuous extraction cycles.
