Beseler 4x5 enlarger . Does exhausr fan suck or blow?

[raymond___k_osmotherly]

I have a Beseler 4x5 enlarger with colour head which I obtained

second hand. It came without cooling fan and tubing. I am hoping to

makeup such a set-up using a small exhaust fan and swimming pool

hose. I can not find out whether the fan is intended to draw away hot

air from the light source or whether it blows cool air into the light

source. I suspect the former is correct (sucks air out)but would be

grateful if a Beseler user could confirm this. Without the fan the

light overheats and shuts down until it is cool again - most annoying!

Many thanks

Ray

The fan sucks air through the head and out. It's a rather powerful fan, noisy, far stronger than the usual muffin fan, about the same as a fan used for a vacuum easel in the graphic-arts industry.

Thanks John; Now I know what to do with the one I have. Vacuum easel; Ya

that's the ticket.

Yep, we all need one. I spent so much time hearing the fan on the stat camera my ears are still ringing.

 

BTW..perhaps I should clarify...the Beseler fan is in a metal box about 10 inches square or so, with a non-collapsible hose running from it to the head. The thing's so loud ideally it should be in another room.
