Hydrofarm Heat Shield Fan Cover
$51.96 $64.95
The Fan Heat Shield blocks the heat generated by inline duct fans from radiating off of them. This means that less heat finds it way into your room, allowing it to be better carried away by your existing ventilation system. This results in a cooler environment, increased plant growth, and more energy savings from increased A/C efficiency.
Fits 4in, 5in, and 6in inline fans
