Dial-A-Speed Fan Speed Controller
Dial-A-Speed By Light Energy ( / LightEnerG ) Fan Speed Controller
May not be exactly as pictured. (Branding design may have changed)
Excellent and tremendously useful (and inexpensive) fan speed controller - plug your fan into this, and this into your electrical outlet, and this simply acts as a 'dimmer' for your fan speed, allowing you to set your fan at your preferred/needed speed and sound level, and to modify it simply, as you please.
Used in conjunction with one of our awesome temperature control options, you can then 'dim' your fan even when it's turned on by the temperature controller, excellent for when you don't need the full power of your fan and do want your fan noise reduced while cooling your space.
Very useful also, for example, if using two of the same fan for your intake and exhaust, and wanting to maintain negative pressure while running your exhaust through a charcoal filter... and more generally super-handy to ensure negative pressure by dimming your intake fan (and, if desired, your exhaust fan with a second Dial-A-Speed) to whatever speed you desire.
