What is the Sigilventus EC Fan and how is it different?
Sigilventus EC Fan is a mixed-flow inline duct fan with an EC motor for smoother speed control, better energy efficiency, and stronger airflow through restrictions like filters and long ducting—compared to typical AC fans.
What sizes does the Sigilventus EC Fan come in and how much airflow does it provide?
The fan is available in 150mm, 200mm, and 250mm sizes, with max airflow of 350 CFM, 710 CFM, and 1065 CFM respectively. Static pressure ratings are around 500–520 Pa, making it ideal for high-resistance setups like carbon filters.
How loud is the Sigilventus EC Fan and how can I reduce noise?
Max noise ranges from 60–65 dBA depending on the size. Keep it quiet by hanging the fan with straps, sealing duct joints, avoiding sharp bends, and running at lower speeds when possible. Whistling or extra noise often means air leaks or tight bends.
Does the Sigilventus EC Fan come with a speed controller?
Yes—it includes an 8-speed manual controller. It also supports 0–10V and PWM signals for advanced setups. Avoid using AC dimmer controllers, as they can damage EC fans or cause erratic behavior.
How should I mount the Sigilventus EC Fan and what ducting should I use?
It can be mounted horizontally or vertically using the included bracket. Match duct size to fan size (150mm, 200mm, or 250mm). Avoid reducers if possible, as they increase noise and reduce airflow.
Can I use the Sigilventus EC Fan for intake, exhaust, or with a carbon filter?
Yes—it's designed for both intake and exhaust. It pairs well with carbon filters and can also handle backdraft dampers. Just install it in the correct airflow direction (arrow on housing).
Will the Sigilventus EC Fan help with temperature, humidity, or odour control?
Yes. It helps remove heat and humidity by increasing air exchange. When used with a carbon filter and passive intake, it also maintains negative pressure to contain odours effectively.
How do I choose the right size Sigilventus EC Fan for my setup?
Base it on your tent volume, heat load, and airflow restriction. If you're using filters or long duct runs, sizing up and running the fan slower usually gives you quieter, more efficient performance with room to adjust.
Should I run the Sigilventus EC Fan continuously or on a timer?
Most growers run the fan 24/7 at a low baseline speed to keep temps and humidity stable. Timers can work, but frequent cycling can lead to noise spikes and uneven airflow.
What comes with the Sigilventus EC Fan?
The box includes the fan unit and an 8-speed controller. Wireless or smart controllers may be available separately, depending on the seller. Always check the product listing for what's included.
Why is my Sigilventus EC Fan stuck at full speed or not responding?
Check the controller connection first. If the control cable is loose or missing, the fan may default to max speed. Start with the included controller to rule out wiring or signal issues.
How do I clean and maintain the Sigilventus EC Fan?
Unplug the fan before cleaning. Check for dust buildup at the intake and in the ducting. If you notice reduced airflow or new noise, inspect the filter and fan area for buildup or loose parts.
Can I use the Sigilventus EC Fan outside of grow tents?
Yes—it works well for drying rooms, bathrooms, garages, sheds, and general ducted ventilation. Just ensure safe electrical installation and keep controllers away from water or high humidity zones.
Is the Sigilventus EC Fan water resistant and compatible with Australian power?
Yes—it has an IPX4 splash-resistant rating and supports 220–240V at 50/60Hz, making it suitable for humid grow spaces and Australian power systems.
What certifications and build quality does the Sigilventus EC Fan offer?
It features a steel housing, high-quality NMB or NSK ball bearings, and certifications like ETL, CE, SAA (plus ERP/HVI on the 250mm model). Built for durability and long-term use.
