Doran L-1212 Overview

Each Doran Light Tight Darkroom Louver is designed to supply just the right amount of air to a particular model exhaust fan.

Note:
Exhaust fans work best in a darkroom equipped with fresh air supply louvers or some other kind of air supply. If there is no air supply to the darkroom the fan will be working against a vacuum and can do nothing.

Exactly what was needed!

I needed a air intake that was light proof for my indoor garden. Couldn't ask for more. Theres a big market for this product aside from just darkrooms. With a slight change in marketing these will be flying off the shelves! 5 star all the way!

Just like it says only NICER!

This is for my NEW darkroom! The exhaust fan is on it's way. Looking forward to use this at home instead of the classroom!

Louver works exactly as it should.

In addition to digital, I still do lots of traditional B&W photography. I finally built my own home darkroom, for which good ventilation is essential. This is the only product I know of that allows for good airflow and is light-tight. You'll also need an exhaust fan at the other end of the darkroom. I'd also suggest installing an airfilter on the inside of the vent to capture all of that basement dust. It's a bit expensive, but this is what one would expect for a specialty product.

Great Product!

I'm a film and darkroom guy. The Doran light-tight air vent is simple and does what it is supposed to--keeps light out of the darkroom while letting fresh air in. It's easy to install and inexpensive compared to many of its competitors. I have no complaints about this product.

Great Louver

Perfect when in combination with a ventilating fan. I use it to keep the fresh air flowing in my new darkroom.

This is a Louver for A-1212 Fans, it is not the fan itself. Unfortunately we no longer have the A-1212 fan. If you are looking for a fan we have the Doran Pro-lab SL/WC Darkroom Exhaust Fan with Wall Cap as a special order item linked here. https://bhpho.to/3iWCUsa. This can be installed into a slanted ceiling, space permitting.

This is just the louver. Think of it as being like a grille that blocks light. There is no fan. Rather, it goes with A-1212 fans.

question

If I install a louver in the door to the darkroom, is there a filter you can install over the louver to keep the dust out and if so, won't a filter compromise the air intake? The darkroom has an exhaust fan where the bathroom window used to be.
Asked by: Clayton Y.
In my application, Im moving ambient air thru a light tight black box of about 64 cubic feet. I have three of the darkroom louvers in the door. I push air into the box with a variable speed fan thru a HEPA filter. With the fan on its lowest setting, I needed three lovers to keep enough air exiting the box, so as not to blowup the box. Sorry, cant tell you the CFM of the fan, but as I mentioned, its variable speed and low speed is low. I mention this to point out that the louver itself blocks a fair amount of air flow. If youre trying to keep dust out, of an area, then your exhaust fan should never be turned off, and air entering the room should be filtered. If your exhaust fan is for fumes, then it needs to be on 24/7 or dirty air could re-enter thru the fan when its turned off, if the fan discharge does not have self or manual closing louvers (kind of like a dryer vent). If the exhaust fan is just for drawing heat out of the room (and you still want to control dust), then remove the fan seal as many room openings as possible and use two fans with HEPA filters (one for intake, the other for exhaust). Most HEPA filters by default are light tight, but will most likely cost more than the L-12152. Understand however that you will now be relying on the ambient air outside the dark room for heating and cooling, unless you have other provisions.
