The SigilVentus EC MixFlow Inline Fan is a low-profile duct fan built around a jet-engine style impeller and a brushless EC motor in a metal housing — high airflow and strong static pressure without the hum, vibration or power draw of an old AC fan. The manufacturer rates it at half the power consumption of traditional duct fans, and every unit ships with an 8-preset speed controller in the box. Available in 150mm, 200mm and 250mm duct sizes, moving up to 1065 CFM.

Fan Size Calculator- Connect the speed controller before powering up — SigilVentus EC fans do not run without a speed control connection
- A detachable fast clamp makes life easier on hard or PVC duct — the fan pops off for cleaning without pulling the run apart
- Size up and run slower — a 200mm at half speed moves the same air as a flat-out 150mm, quieter and on less power

Common Questions
Does it come with a speed controller?
Yes. Every fan includes an 8-preset speed controller, a 5-metre control cable, a full-speed plug, and adaptors for RJ45 and 3-pin controllers.
Will it run without a controller connected?
No. SigilVentus EC fans require a speed control connection before power up — connect the included controller (or a Smart Controller) first, then plug in.
Can it pull through a carbon filter?
Yes. All three sizes deliver 51-53 mmH₂O of static pressure, which is what matters for filtered and long duct runs — airflow holds up under restriction instead of collapsing.
Which size do I need for my tent?
The 150mm suits most single tents up to around 1.2x1.2m, the 200mm covers larger tents and filtered runs, and the 250mm handles big rooms and multi-tent setups. Use our Fan Size Calculator above for a match based on your exact dimensions.
What is the difference between this and the Silenced Fan?
Same EC motor and airflow figures — the Silenced version adds a steel acoustic housing with sound-absorbing foam for quieter running, while this MixFlow model is lower profile, lighter and easier on the budget.
