Best way to extract air from tent in loft?

[Bethmeg]

Thank a for the reply but what if I have an air cooled light reflector? Won't I need to use ducting in between fan and filter?
Thanks Dave

Air cooled lighting should have a separate extraction fan and duct from the main extraction for it to work properly.

I have a window in my loft that rarely gets opened,only on really hot days.

I passive intake through the vents on the tent.

I extract into the same space,I just have the ducting pointing away from the tent.

So in effect I am recirculating the air.

As was said if the loft isnt insulted and boarded out fully then the fresh air will make its way through somehow,works for me.

Same here

i do have a chimney yeah its not used as we have gas central heating. i also have a vent in the fascia where the bathroom extractor fan blows now.
maybe i could just unclip the bathroom ducting and use that for fresh air coming in?

also can i just knock out 1 or 2 bricks and seal around the duct?

In my old home where i had a loft big enough for a tent i knocked bricks out of my old chimney and had my extraction going through there, as long as your careful it wont be a issue and for intake i had a small vent in my loft from outside i just had my intake from there drawing cold air directly to where my fan was blowing, but i had a net over my fan to stop bugs dust and so on from entering.
