FAN RK 150m (6″) AC – 470m³/hr Inline Extraction Fan

Reliable High-Airflow Ventilation for Grow Rooms & Extraction Systems

The FAN RK 150m (6″) AC Inline Fan is a durable, high-performance extraction fan designed to provide consistent airflow for hydroponic grow rooms, grow tents, workshops, and general ventilation systems. Delivering a maximum airflow rate of 470m³/hr, this fan is ideal for maintaining stable temperatures, humidity levels, and fresh air exchange in small to medium-sized growing environments.

Built with a robust mixed-flow design, the RK series combines the pressure capabilities of centrifugal fans with the airflow efficiency of axial fans. This allows the fan to maintain strong performance even when connected to carbon filters, long duct runs, or bends in ventilation systems.

Its compact housing and straightforward installation make it a dependable solution for growers who need efficient air movement without complicated setup requirements.

Key Features:

• Fan Size: 6″ (150mm) duct compatibility

• Maximum Airflow: 470m³/hr

• AC Motor: Reliable and simple mains-powered operation

• Mixed-Flow Technology: Maintains airflow efficiently through ducting and filters

• Suitable for Extraction & Intake: Can be used to remove stale air or bring fresh air into grow spaces

• Durable Construction: Designed for continuous operation in indoor environments

• Compact Design: Fits easily into most ventilation setups

• 1 × FAN RK 150m (6″) AC Inline Fan

• Pre-wired power cable

• Integrated mounting bracket (depending on version supplied)

• Manufacturer label with technical specifications

Installation

Install the fan inline with 150mm ducting using appropriate duct clamps or fastening collars. The airflow direction is marked on the fan housing to ensure correct orientation during installation.

The fan can be used in several configurations:

• Connected directly to a carbon filter for odour extraction

• As part of an intake system supplying fresh air

• Inline within longer ducting systems to improve airflow movement

For the best performance, minimise unnecessary bends and keep duct runs as straight as possible to reduce resistance.

Environmental Recommendations

The RK 150m is particularly effective in:

• Small to medium grow tents

• Propagation rooms

• Drying spaces

• Hydroponic environments requiring steady air exchange

Pairing the fan with a compatible carbon filter and acoustic ducting can significantly improve overall climate control and reduce operational noise.

Maintenance

• Regularly inspect the fan and ducting for dust buildup

• Keep air pathways clear to maintain airflow efficiency

• Disconnect power before cleaning or servicing

• Ensure the fan is securely mounted to minimise vibration

Because this is an AC fan, speed control compatibility may depend on the controller used. Always use compatible fan controllers designed for AC motors if variable speed adjustment is required.
