A grow tent air filtration system with all the necessary inline components you need to ventilate your grow space. By assembling these essential pieces, this package will help you quickly get your grow build started and eliminate the guesswork of purchasing them individually. This inline fan kit features the CLOUDLINE Series fan with 10-speed controller, capable of delivering powerful yet quieter performance. Paired with a carbon filter using Australian virgin charcoal to block odours from seeping out of your grow tent. These two pieces are connected by a set of flexible ducting with four layers of protection to properly direct airflow away. Accessories include duct clamps, prefilter cloth, rope clip hangers, and hanging straps to complete the installation. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.

An air filtration kit with everything you need to cool, ventilate, and control odours in your grow space.

Features the CLOUDLINE inline fan with speed controller, delivering silent and efficient performance.
Carbon filter with prefilter cloth uses 1200+ IAV activated charcoal for high efficacy odour blocking.
Four-layer flexible ducting connects the inline fan and filter to your grow tent to direct airflow.
Kit Duct Size: 4” | Fan Airflow: 165 CFM | Noise 29 dBA | Carbon Thickness: 38 mm | Ducting Length: 25 ft.

Inline Fan

The grow tent ventilation kit is headlined by the CLOUDLINE Series of inline duct fans, featuring a 10-speed fan controller. Using stator blades and dual hydrodynamic wind circles, the CLOUDLINE achieves high-performance airflow in restrictive applications thanks to its mixed-flow design. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. This frame is crafted with a plastic mounting base to reduce noise from vibration and can be mounted in any direction. Dual ball bearings give this inline fan a 67,000-hour lifespan, backed by an IP-44 rating, resisting dust and splashing liquids.

A 10-speed fan controller is paired with this inline fan to optimise airflow levels and noise in many applications. The fan’s PWM controls enable it to smoothly set fan speeds and operate at extremely low RPMs with no motor noise. Along with this wired speed controller, the CLOUDLINE is also compatible with the following controllers:

B-Series Temperature Controller
CONTROLLER UNC529
CONTROLLER 69
CONTROLLER 67
CONTROLLER 63

Carbon Filter

Pair the CLOUDLINE inline fan with a carbon filter to effectively block odours from escaping your grow tent. Its 38mm thick carbon bed is made up of premium Australian activated charcoal with a 1200+ IAV rating and RC412 microporosity. This enables the filter to adsorb more odour molecules for up to 33% longer than other inline filters. Use with the included prefilter and reversible flanges (to flip the carbon bed) can further extend its lifespan. The heavy-duty build consists of aluminium flanges and a galvanised steel mesh to allow 100% air passthrough.

Ducting

Install flexible ducting to connect your inline fan and carbon filter with your grow tent and route stale, odorous air away. Each included set features four layers of protection that resist tears and leaks, bound by internal steel wires to retain its shape. The outer layers are composed of dual PVC thermoplastic to protect the inner layers from cuts and prevent leakage. The inner layers are made of flame-resistant aluminium to withstand warmer airflow. 25 feet of ducting gives you flexibility to customise the length of your ductwork to fit your application.
