Fan Max 250mm (10″) – 1740m³/hr – High

High-Powered Air Extraction for Large Grow Rooms & Ventilation Systems

The Fan Max 250mm High Power Inline Fan is a robust ventilation solution designed for growers and commercial users who require strong, consistent airflow across larger spaces. Delivering an airflow rate of 1740m³/hr, this 10-inch inline extractor fan is ideal for removing excess heat, humidity, and stale air from grow rooms, grow tents, drying spaces, and other high-demand ventilation environments.

Built with a durable mixed-flow motor system, the Fan Max combines the pressure capabilities of centrifugal fans with the airflow efficiency of axial fans. This allows the fan to maintain strong air movement even when connected to long duct runs, carbon filters, or multiple bends in a ventilation setup.

The high-performance motor is housed within a sturdy casing designed for continuous operation, making it suitable for both hobby and professional grow environments where reliable extraction is essential for maintaining stable climate conditions.

How to Use the Product & Best Usage Recommendations:

Installation

Install the fan inline within your ducting system using compatible 250mm ducting and clamps. The airflow direction is indicated on the fan housing and should match your intended extraction or intake setup.

For extraction systems:

• Position the fan near the top of the grow area where warm air naturally accumulates

• Pair with a matching 250mm carbon filter for odour control

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

Environmental Control

The Fan Max 250mm is particularly effective in:

• Large grow tents

• Multi-light grow rooms

• Warm environments requiring rapid heat removal

• Drying rooms needing stable air exchange

Maintaining proper airflow helps regulate:

• Temperature

• Humidity

• CO₂ exchange

• Prevention of stagnant air and mould development

Best Usage Recommendations

• Use with an appropriate fan speed controller if reduced airflow or quieter operation is required

• Ensure all duct connections are tightly sealed to avoid pressure loss

• Clean fan blades and ducting periodically to prevent dust buildup and maintain efficiency

• Match with a carbon filter rated close to the fan’s airflow output for balanced performance

Because of its high airflow capacity, this fan is best suited to medium-to-large extraction systems where lower-powered fans may struggle to maintain adequate air exchange.
