FAQs
The variable speed controller allows you to manually adjust fan speed based on real-time temperature readings from the built-in thermometer. You can increase airflow when temperatures rise and reduce it during cooler periods for optimal climate control and energy efficiency.
The R6 kit excels in household and horticultural applications including grow tents, workshops, and basements. Its 390 CFM capacity effectively ventilates medium-sized spaces, making it a great fit for a VIVOSUN 3'x3' Smart Grow Tent Kit.
The R6 fan operates at under 37 dB, which is quieter than a typical library. The durable plastic housing and blade construction are specifically designed to reduce noise, making it suitable for residential use without disturbing daily activities.
The variable speed controller is key. You can adjust the fan speed to increase or decrease air exchange, which directly impacts humidity. For a detailed guide, read our article on how to lower humidity in your grow room.
The carbon filter uses 1200+ RC 412 rated activated carbon for superior elimination of odors, chemicals, and other airborne impurities. This premium-grade carbon provides excellent absorption for any application requiring air purification.
The maximum ambient operating temperature is 104°F (40°C). This makes it suitable for most indoor applications, including grow tents with lighting systems, and attic ventilation during summer months while maintaining reliable performance.
Yes, the 6" ducting system is compatible with standard extensions and connectors. While the 390 CFM capacity can handle moderate extensions, keep in mind that very long or complex runs may slightly reduce overall airflow performance. You can find compatible parts in our inline fan systems collection.
