Per-Pack Information: This listing is for a pack of 2 speed controllers, each designed to manage a single inline duct or exhaust fan. Every controller operates independently, allowing you to set different speeds for separate fans and tailor airflow precisely to each ventilation location.
Practical Electrical Specifications: Rated for 120V AC input with a maximum current of 3 amps and to 350W, matching most small to medium inline duct fans. Equipped with a 3-pole grounded American plug, offering broad compatibility with standard household outlets.
3 Adjustable Fan Speeds: Features a single easy-to-use knob with three clearly defined speed modes-low, medium, and high. Adjust the fan output to match changing ventilation demands, from gentle airflow for quieter environments to maximum power for rapid air exchange.
Versatile Usage Scenarios: Ideal for inline duct and exhaust fans used in grow tents, greenhouses, warm houses, basements, kitchens, and offices. Helps regulate temperature, humidity, and airflow, supporting better plant growth, odor control, and overall indoor air quality.
