Mixed Flow Filter Kit – Grofan 150 with Progrow 150 x 800 (FREE Duct)

"We offer a complimentary duct of your choice with your purchase."

The 600-1800W Mixed Flow Filter Kit includes the Grofan 150 and the Progrow 150 x 800 filter. The Grofan 150 has a maximum air flow rate of 530 m³/h, making it an ideal choice for use with rigid and flexible ducting. This energy-efficient Mixed Flow In-Line fan operates quietly and has a compact design that allows for easy installation in many ducted applications. Its impeller blade design with guide vanes provides optimal pressure characteristics and simple connectivity, ensuring quieter and more efficient operation. The Grofan Mixed Flow In-Line fan can be mounted horizontally or vertically to achieve its optimum performance, and it features a Hi-Lo in-built fan speed control switch to suit your needs. To prevent unwanted vibration, the fan should be mounted within the ducted system and isolated from the building structure using anti-vibration mountings.

If you haven't heard of Progrow before, don't let that deter you. Progrow has extensive experience in all aspects of hydroponics and commercial gardening, which they have used to develop an innovative, cost-effective product range specifically tailored to the needs of growers.

Progrow's carbon filters are the result of years of development and testing in real-world conditions to determine the most effective carbon grade and filter design. These filters are constructed from galvanized steel instead of aluminum, making them easier to transport and less prone to denting (ideal for internet sales). They come in discreet packaging and feature built-in hanging brackets to facilitate installation.

The greater the internal surface area of the carbon, the better its ability to absorb odors and the longer it will last. Progrow uses virgin granular 4/12 graded carbon, which is a larger size than some other brands, resulting in superior airflow. The more dust there is in the carbon, the harder any fan pulling through it will have to work to move air.

Progrow filters have a set carbon bed width, as they have found that more carbon does not necessarily make a better filter. It's crucial to remember that when filtering air, odors are in contact with the carbon bed for only a fraction of a second. The quality and effectiveness of the carbon is much more critical than how much there is. Additionally, the deeper the carbon bed, the harder your fans will have to work to move air through it. Progrow filters have a 50mm bed, which they believe strikes the best balance between lifespan and airflow.

Progrow sources its carbon from Australia because of its consistent quality and unique composition, which provides a greater internal surface area than carbon from any other region. Don't be fooled by other brands marketing their carbon as 4/12; if it's not Australian virgin granular 4/12, it's not the same.
