Spider Farmer 4" Inline Duct Fan with Temperature & Humidity Controller

Spider Farmer’s 4” Inline Duct Fan with Temperature and Humidity Controller moves an impressive 205 CFM of air while remaining whisper quiet at only 28db. The programmable smart controller gives you more control over your environment with controls for fan speeds, humidity and temperature at your fingertips.

Powerful Inline Fan – This inline fan’s mixed flow design works together with an EC motor to ensure a truly energy efficient fan - using only 40 watts of power with excellent airflow of up to 205 CFM. The SF-4 Inline Fan is whisper quiet, producing only 28DB of noise so you'll never hear it running! Lightweight and balanced ABS blades reduce the unit’s airflow resistance, increasing airflow by 40%. The adjustable speed controller comes with a long power cord so you can place the fan outside the tent if you prefer for easier control. ETL FCC listed, safe to use.

Built to Last – Spider Farmer’s inline exhaust fan housings are made of premium ABS plastic for superior durability, they’re IP42 rated so they’re highly resistant to dust and liquids, and these powerful fans perform well even in the harshest environments.

Smart Controller – Spider Farmer’s Programmable Smart Controller features 10 fan speeds, easy to program humidity and temperature controls with 4 easy settings and alarms to help keep your space at optimal temperature and humidity.

Daisy-Chain Compatible – Connect 2 4” exhaust fans together to share the same controller for convenient control of both simultaneously. The long power cord makes setting up the fan inside or outside your space a snap.

Use Almost Anywhere – Spider Farmer exhaust fans have been designed to circulate air to support cooling, heating systems and of course, air-circulation. This 4” inline duct fan is an excellent choice for grow tents, closets, bedrooms, the attic, basements and more.
