SigilVentus PROLINE 4” EC Inline Duct Fan System with Temperature & Humidity Controller, 4-Inch

SIGILVENTUS 4” PROLINE EC INLINE FAN SYSTEM WITH SMART CONTROLLER is designed for compact grow tents and equipment closets that require durable performance with intelligent airflow control. Featuring a high-efficiency EC motor and all-metal construction, this system delivers waterproof, vibration-free ventilation in tight spaces.

SMALL SIZE, STRONG PERFORMANCE
The 4-inch inline fan pushes up to 160 CFM with 34 mmH₂O static pressure—ideal for 2x2 ft to 3x3 ft grow tents, under-canopy airflow, or supplemental cooling in precision-controlled environments. The EC motor spins at up to 5000 RPM, while maintaining a low noise level of 51.6 dBA.

ALL-METAL HOUSING WITH IPX4 PROTECTION
Housed in powder-coated steel and rated IPX4, the fan is resistant to moisture and designed for long service life in humid environments. Its compact footprint and stable airflow make it ideal for small duct runs and hydroponic micro-setups.

FULLY AUTOMATED FAN CONTROL
Paired with the C8 climate controller, this system reacts in real time to your grow space conditions. The 5-meter sensor monitors temperature, humidity, and light intensity, and automatically adjusts fan speed through 7 programmable modes including Auto Trigger, Day/Night, Timer, Cycle, and Circadian.
