FAN Isomax Acoustic AC 200mm – 870m³/hr 3 Speed (8″)

High-Powered, Low-Noise Ventilation for Demanding Grow Environments

The Isomax Acoustic AC Fan 200mm (8″) is a high-capacity inline fan engineered for growers who require strong airflow with significantly reduced noise levels. Delivering up to 870m³/hr, this fan is well-suited for medium to large grow rooms, where maintaining stable temperature and humidity is essential.

Unlike standard inline fans, the Isomax features a fully insulated acoustic housing, designed to dampen motor noise and airflow turbulence. Internally, it uses a reliable AC motor paired with a 3-speed selector, allowing growers to balance airflow and noise output depending on environmental demands.

The fan is commonly paired with carbon filters and long duct runs, where consistent pressure and airflow are required without excessive sound—making it a practical choice for both hobby and professional setups.

Key Features:

• Airflow Capacity: Up to 870m³/hr

• Flange Size: 200mm (8″)

• 3-Speed Control: Built-in speed settings for flexible airflow management

• Acoustic Insulation: Integrated foam lining reduces operational noise

• AC Motor: Durable, simple, and dependable performance

• Cylindrical Design: Easy to integrate into ducting systems

• Application: Suitable for intake or extraction in grow tents and rooms

• 1 × Isomax Acoustic AC Fan 200mm (8″) – 870m³/hr

• Integrated 3-speed switch (pre-wired)

• Power cable (UK plug fitted)

• Mounting-ready outer casing (brackets may vary depending on batch)

How to Use the Product & Best Usage Recommendations:

Installation Guidance

Install the fan inline within your ducting system, ensuring airflow direction matches your setup (usually from carbon filter → fan → خروج ducting). The fan can be mounted horizontally or vertically, but should always be securely supported to minimise vibration.

Use appropriate ducting (preferably acoustic or insulated ducting) and secure all connections with clamps to prevent air leaks.

Speed Settings & Control

The built-in 3-speed switch allows you to:

• Low speed: Maintain airflow with minimal noise (ideal during early growth or cooler periods)

• Medium speed: Balanced performance for most grow stages

• High speed: Maximum extraction during peak heat or late flowering

Avoid running the fan in overly restricted systems without adequate intake, as this can reduce efficiency.

Best Usage Recommendations:

• Pair with a 200mm carbon filter for odour control

• Use acoustic ducting to further reduce noise levels

• Position the fan outside the grow tent where possible to minimise heat and sound inside the space

• Regularly check for dust build-up in ducting and filter resistance

• Ensure adequate passive or active intake to maintain balanced airflow

This fan is ideal for growers needing high airflow performance with reduced acoustic impact, particularly in environments where noise management is important.
