There has been talk about ventilation in the darkroom before.
What I need you to help with, is to choose between two different set ups that are offered by the same company.
Those two models are sold here and I am not willing to look for something else really, especially since its very hard to find most recomendations here in Crete, or even Greece. Also because of the bulk and weight I rather not order from abroad.
The two offers are made by an italian company, Aspira.
My choices are:
* a direct wall mounted air exhaust
- large size of 34x34cm sqaure
- needs a new hole on the darkroom wall around 26cm square
- gives me about 20-25 changes of air in an hour (680 m3/h)
- makes noise of about 49dB from within 1,5m
- will be mounted on the wall at the right of the sink, just where it ends
- it has grilles and opening and closing flaps
- comes with seperate speed control unit
- it doesn't really stick out much
- its the more expensive
* an in-line centrifugal fan
- can be attached to the same pipe I had of a dead exaust unit
- it will need a bit of pipe more to sit properly and protect the fan opening
- it will stick out (about 20cm diameter)
- it will give me about ten changes of air in an hour (235 m3/h)
- it doesn't have a speed control unit
- makes noise of about 62dB
- I can find larger and stronger models but they can become really large
- its cheaper
My darkroom for those who haven't seen it in the darkroom photo thread its about 3x3x2m.
Air will come in from the opposite end of the room via an air conditioning unit.
My darkroom is mostly in the open, apart from the wall that the sink rests against which is the wall of another similar room. All the other three walls are outside walls.
Please look at the included photo.
a) is where the direct fan will sit
b) is about where the in-line fan with a pipe will sit
c) is where the old unit was
What do you suggest?
