Ventilation kit 250 ECO, grow room ventilation & carbon filter

Complete 125 mm extraction kit for small grow tents with odour filtration

The Ventilation Kit 250 ECO combines a two-speed duct fan, a matching activated carbon filter and the necessary connection accessories in one compact extraction system for small grow tents. Depending on the selected speed, the fan moves 220 or 280 m³/h of air, helping to remove warm, humid and stale air from the growing area. At the same time, the activated carbon filter reduces characteristic odours in the extracted air. The kit is pre-wired, making it a practical option for growers who do not want to assemble an extraction system from separate components. Other matched systems are available in the extractor fan kits for grow tents range.

Two fan speeds for adjustable extraction

The included Ventilution Mixed In-Line fan provides two selectable speed settings with airflow rates of 220 and 280 m³/h. Power consumption is 23 and 37 W respectively, allowing the extraction rate to be adapted to different requirements. Growmart specifies the kit for small grow tents using lighting up to a maximum of 250 W. The airflow actually required will also depend on factors such as ambient temperature, heat output and duct routing. The fan is also available separately as the Ventilution Mixed In-Line 220/280 m³/h.

Activated carbon filtration with 125 mm connections

The supplied Economy activated carbon filter has a 125 mm connection and is rated for airflow up to 240 m³/h. Activated carbon captures odour-producing compounds before the extracted air leaves the grow tent. A 125 mm fast clamp allows the filter and fan to be connected directly. As with any carbon filtration system, the resistance created by the filter can reduce the fan's effective airflow. A suitable replacement option is the PrimaKlima 240 m³/h carbon filter with 125 mm connection.

Connection accessories included

The kit includes 3.30 m of flexible aluminium ducting for directing extracted air away from the grow tent, together with the required hose clamps. A mounting bracket is also supplied for optional wall installation of the duct fan. In an appropriately sized small grow tent, the negative pressure generated by the extraction system can allow fresh air to enter through open passive intake vents, so a separate powered intake fan is not necessarily required.
