AC Infinity CLOUDLINE A8, Quiet 8″ Inline Duct Fan with Speed Controller, EC Motor – Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

My kids rooms are a very long duct run distance from the central unit and their rooms have always been warmer in the summer and cooler in the winter, to the point that I have contemplated getting portable A/C unit(s) to help cool the room(s). Luckily from the duct distribution area both the kids room were on a single duct that was split, insert the 8″ booster unit before the split, installed 2×4’s as a frame across the trusses, then installed the blower motor with a little cut up yoga mat between wood & trusses and motor & wood for a little extra dampening and its as quiet as can be, other than as much air coming through the register as we want you cant tell its installed.Bonus: On my furnace circuit board I have an EAC connection and this allowed me to use that as my hot while connecting my neutral and ground in the connections box, this controls the off & on of the booster fan (my hvac system allows up to 1 amp off the EAC connection) so I had to make sure the motors draw was less than 1 amp. I am not an expert so if you don’t know what you are doing hire someone who does, this is informational only. But I couldn’t be more happy right now, worth the $$$.
