The SystemAir RVK 125MM Circular Duct Fan is a compact, powerful, and quiet inline fan designed for continuous air extraction or intake in grow tents, greenhouses, wet rooms, and ventilated cabinets. With a maximum airflow of 323 m³/h, it delivers reliable and efficient performance in environments requiring consistent airflow.

Crafted from fibreglass-reinforced polypropylene, the RVK fan is lightweight, airtight, and corrosion-resistant. Its backward curved impeller is dynamically balanced and paired with a robust external AC rotor motor, ensuring low noise levels (43 dB) and long-term durability. This 125 mm fan is speed-controllable via a stepless thyristor or 5-step transformer and includes manual-reset thermal protection for added safety.

Built for flexibility, it can be mounted in any indoor position using the included bracket and fast clamps for secure, vibration-free ducting.

A reliable, low-maintenance solution for small to medium hydroponic grow rooms or damp spaces needing quiet, continuous ventilation.
