VIVOSUN 3-Speed Variable Fan Speed Controller for Inline Duct Fans

Overview

The VIVOSUN Variable Fan Speed Controller delivers precise airflow control for inline duct fans. With a single switch offering three speeds, you can tailor ventilation to changing conditions without always running at full power. This balance of performance and efficiency helps you manage comfort and airflow more intentionally in a variety of spaces.

What makes it useful

In real-world setups, having adjustable speed means you can fine‑tune air movement to match the environment. The controller supports safe operation with most inline fans thanks to a built‑in grounded plug, and its rugged 6 ft cable keeps installation flexible. The product is designed for standard 120V/60Hz systems and up to 15A, making it a practical upgrade for many ventilation tasks.

• Three speeds: low, mid, and full for flexible ventilation control
• Energy-friendly operation: avoid waste by not running at full speed unless needed
• Safe operation: grounded plug ensures compatibility with inline fans
• Easy placement: a 6 ft cable provides flexible setup in different spaces

Usage scenarios

• Grow tents and horticulture spaces where airflow may need adjustment
• Warm rooms, basements, or offices where transient ventilation is beneficial
