The 8 Inch Prime EVO EC and Where EC Pays Off
With an EC motor the number that matters stops being watts at full speed and becomes watts at the speed you actually run. This one peaks at 793 CFM and 1.6A, with the impeller topping out at 2,995 RPM. Ease it down and the draw falls away with it. The motor is rated IP54 behind an IP44 terminal box, and the whole unit weighs 8.8 lbs.
Wiring an 8 Inch EC Inline Fan to a Controller
The controller is really the point of a fan like this, so it is worth planning for one from the start. Any 0-10V source will drive it, the MTP 21 and most grow-room climate controllers included. Without one you are running an efficient motor flat out and losing what you paid for. The rated ambient range of -22°F to 122°F covers an unheated garage comfortably. Ruck publishes no dB figure for this size. Retailer listings also split between the peak figure and 756 CFM, depending on the test point. Treat the higher number as a maximum rather than a promise. Bracket, cord and a three-year warranty come with it.
