G.A.S. SystemAir Fans
SystemAir fans are offered in the Revolution range with quiet EC motors and aerodynamically shaped blades for high airflow even at higher duct pressure. They are suitable for larger tents where a standard axial fan is no longer enough.

SystemAir is a brand of duct fans in the Revolution and Revolution Silenced ranges, which you can find in the offer with a classic AC motor as well as a more modern EC motor. The EC version allows smooth speed control from 0 to 100 % without the characteristic humming known to anyone who has controlled an older AC fan with a phase controller.
How to choose the right model
The key is airflow in m3/h relative to the volume of the growing space and the resistance created by the filter, ducting and bends. Smaller diameters of 150-160 mm with airflow around 750-800 m3/h cover medium-sized tents, while diameters of 250-315 mm with airflow over 1800-2200 m3/h are intended for large grow rooms or spaces with longer ducting and higher pressure resistance.
- Revolution EC Vector - aerodynamically shaped blades, higher efficiency than comparable AC models, suitable for more demanding pressure conditions.
- Revolution Silenced V2 EC Vector - the same EC technology plus a silenced body, appreciated where low noise matters.
Alongside SystemAir, we also offer duct fans from other brands - Prima Klima, RAM or AC Infinity, if you are looking for a different balance of performance, noise and control. Before buying, it is worth matching the fan diameter with the diameter of the duct and odour filter so that the ventilation works as one system.
