Systemair RVK Fans

German-built inline airflow that just keeps running

Systemair RVK Fans are inline duct fans long treated as the industry standard for grow tent and grow room ventilation. Manufactured in Germany with a maintenance-free motor, they move large volumes of air to control temperature, manage humidity and replenish CO2, and they are compact enough to suit most soil, coco or hydroponic setups. The range spans 100mm to 315mm ducting, delivering from 184 m3/h up to 1,362 m3/h, and every model can be paired with a fan speed controller for fine airflow control.

Fixing heat build-up and humidity spikes from poor ventilation

Weak ventilation lets heat from grow lights accumulate, humidity climb during flowering and stale air starve plants of fresh CO2 - all of which slow vegetative growth and knock back yield. An RVK fan keeps consistent airflow moving through the room, removing hot, humid air while drawing in fresh air to support nutrient uptake, stabilise temperature and humidity, and cut the risk of mould as buds fill out.

Key Benefits

• Industry-standard inline duct fan trusted by indoor growers
• 184-1,362 m3/h airflow across the 100-315mm range for tents and full rooms
• Made in Germany with a maintenance-free motor for long service life
• Extraction or intake - use for exhaust through a carbon filter or fresh-air supply
• Speed-controller compatible for adjustable, quieter airflow

How to Use

• Install the fan inline within your ventilation ducting.
• Connect between the carbon filter and ducting for extraction, or position it to supply fresh air.
• Secure duct connections with clamps or aluminium tape to prevent air leaks.
• Connect to a suitable IEC power lead (sold separately).
• Optionally add a compatible fan speed controller to fine-tune airflow.
• Run continuously or adjust speed as needed to hold stable temperature and humidity.
