Fan

[Kharn]

I just purchased this fan because I have a glass terrarium, the fans aren't powerful but they will provide adequate air movement within the terrarium!

The fans are made by 'BOYU' for aquariums and come in 2 to 6 fan setups this is the 5 fan which should sit neatly along 1 side of my terrarium, I'd of gone 6 fans if I felt that it would fit all up but think its just too long a little bit.

Cheap to by and cheap to run this rack of 5 fans chews a meager 4watts!

If it's running off a 12v input you can put a PWM module on it to adjust the speed.

So this would sit inside the terrarium? How big is your setup? Some chams may not appreciate directly blowing air from very close range. The constant movement of all the blades may worry them and it may dry out the cage fairly quickly. Watch the humidity levels. What about putting this fan on top of the cage frame so it blows air across the top? That will still pull air out and circulate it but it wouldn't be as direct.

The airflow generated is barely enough to move a tissue I'll get a pic later.

The ambient humidity of the area that the terrarium sits is around 70%-80%

Terrarium itself is 48"L x 18"W x 36"H
