We have 4 fans vertically mounted pulling air from a plenum and delivering into a plant room throu louvres. Flow rate is 60,000m3/h per fan with only 3 fans running at any one time. Each the fans are long cased axial type with internal motor.
The manufacturer states that the maximum RH for the fans is 95% and if this is to be exceeded, the manufacturer has to be notified of this.
Why is the 100% likely to be a problem? Is it the motor? Or is condensation likely due to pressure changes within the unit?
Also, has anyone any experience in mounting fans such as these within a structural floor which currently has a square void for accepting the fans.
There will be louvres on top of the discharge. The flanges has flanged ends which I assume would have a ring adaptor plate fitted to bolt down via anti vibration mounts from the floor above. Which in effect means the units are hanging from the floor above. This detail TBC with manufacturer. The units weigh approx 900 kg each.

John
