Nice looking installation Andeas.
I have a querey that is open to all to respond:
In a horizontal installation like Andeas' the belt twists 90deg between bottom pully and the idler pulleys, then it twists 90deg again between the idler pulley and the fan. If the idler pully were set at an angle then the belt would not be required to twist as much. The idler pully would however, be required to be tangential to the bottom pulley (and the fan?) so that would restict its location to <45 deg (the ideal angle) but I would expect that any reduction in twist would have been beneficial for belt and idler bearing longevity. Just a thought?
