Product Description
An air filtration system for grow tents with all key components needed for effective ventilation of the grow environment.
This kit combines everything in one package to get started right away – no guesswork or tedious searching for individual parts. At its heart is the CLOUDLINE A8 inline fan with 10-speed controller, offering powerful performance with quiet operation. It is complemented by a carbon filter with Australian virgin charcoal that reliably prevents odors from escaping the tent. Both components are connected by four-layer flexible ducting that routes the airflow safely to the outside.

CLOUDLINE A8 Inline Fan
Using stator blades and two hydrodynamic air channels, the CLOUDLINE A8 achieves strong air circulation thanks to its mixed-flow design – even when air movement is heavily restricted. The motor housing with impeller and blades can be removed for cleaning. The plastic frame reduces vibration noise and allows mounting in any position. The dual ball bearings are rated for around 67,000 hours, and the IP-44 rating protects against splashing water and solid objects.
10-Speed Controller
The speed controller precisely adjusts airflow and noise level for different applications. Thanks to PWM control (PWM: pulse-width modulation), fan speeds can be regulated especially smoothly – even at very low speeds and without motor noise.
Carbon Filter
The 38 mm carbon bed of the carbon filter consists of Australian activated carbon with an IAV of 1200+ and RC412 microporosity. This allows the filter to absorb odor molecules considerably longer than conventional inline filters. The included pre-filter and the reversible flanges (to flip the carbon bed) extend the lifespan further. Aluminum flanges and galvanized steel mesh provide stability with full airflow.
Four-Layer Ducting
The 7.6 m ducting has an outer layer of PVC thermoplastic, an inner layer of aluminum foil and a steel spiral for structure. It connects the fan and filter to the tent and routes the air cleanly to the outside.

Everything in One Package
In addition to the fan, filter and ducting, the package includes duct clamps, pre-filter, rope hangers and hanging straps – for quick and easy installation.
UIS PLATFORM
Speed controller included – UIS controller optional
The included speed controller covers the basic functions. For automatic control, the fan is compatible with UIS controllers (UIS: Universal Infinity System).
UIS controller sold separately, for example the CONTROLLER AI+.

Safety and Warning Information
Power and Cables
- Connect only to properly installed, grounded outlets that meet the electrical requirements of the product.
- Do not use damaged cables or plugs. If damaged, disconnect the device from the power supply immediately and have it inspected by a qualified professional.
- Use only original cables and suitable accessories from the manufacturer. Other cables or adapters may compromise safety.
- All connections must be secure, correct and safely made before operation.
- Use UIS cables only for control connections – never to connect to mains power.
- Always unplug the power cord before cleaning, servicing or modifying the device.
Fan and Filter in Operation
- The inline fan contains moving parts. Operate only when fully assembled, with covers correctly attached and in a safe environment.
- Do not insert foreign objects into the fan or filter. Never reach into the fan during operation.
- Before operation, make sure there are no tools, packaging parts or other objects inside the fan housing or filter.
- The ducting and filter must not be kinked, crushed or blocked – air must be able to circulate freely at all times.
- Do not cover the fan and filter during operation.
- When installing in grow tents or closed systems, always ensure adequate air intake and exhaust to prevent overheating and moisture buildup.
- The carbon filter must not get wet or come into contact with water – loss of function and risk of mold.
- Check the filter regularly for dust buildup and wear. Replace the filter if airflow is noticeably reduced or it is visibly dirty.
- Use the filter only for its intended purpose in grow applications or room air systems. Do not use for filtering toxic, corrosive or flammable fumes.
- Do not place or spill liquids on or near the device.
- Do not drop the device or expose it to strong impacts or vibration.
- Never use the device in explosive, chemically contaminated or extremely humid environments.
- The device is not intended for outdoor use.
- Use the device only for its intended purpose as a ventilation and filtration unit.
- Do not allow use by persons with reduced physical, sensory or mental capabilities without supervision.
- Keep away from children and pets.
Maintenance, General and Disposal
- Read the complete user manual before installation and operation and keep it for future reference.
- Repairs or modifications may only be carried out by authorized qualified personnel.
- Improper installation or use may result in injury, electrical hazards or damage.
- Do not dispose of this product with household waste – return it to a collection point for waste electrical and electronic equipment (WEEE 2012/19/EU).
