Height of air duct inside a warehouse

[Hasni2]

What should be the approximate height of a supply air duct inside a warehouse whose side walls are 6 meters high and racks for storing goods would be 5 meters high. I am more interested in knowing the height if air diffuser grille from FFL is this warehouse. Thanks

If the rack is 5 metres high, ask what the largest item placed on that rack is going to be. Then make sure your duct clears that by at least 30 centimeters to allow for forklift placing.
