National fans in Al Aweer

[Tais]

i've decided to replace the existing fans that i initially placed in the cow barn since the 2 SMCs i placed there earlier had their motors jammed and i thought it was better to replace the relites

4 nationals in total initially, 2 were from early 90s and 2 were from the late 90s or early 2000s, since there were 2 that accelerated fast and 2 took time to accelerate.. i also replaced the motor casings with the messed up ones from my 80s nationals









however, one of the early 90s national was producing some sparks when operating, its probably short circuit somewhere, the fan worsened and suddenly blowed up and smoke came out of the motor.. i always thought the spark was due to electrocution of wasps that had their hives inside the electrical panel and ignored it, not from the motor itself

i transplanted a spare late 2000s hayashi motor inside the national cover, it spins faster but with loud hums




a nest on one of the national fans!















here is the video of all of them operating at once one of the nationals spins slower in the video due to the SMC regulator, there was nothing wrong with the motor

This is a very cool install!
