Terrarium / vivarium fan holder. Designed for 50mm x 10mm fan with fan oriented to blow air up toward the top. Unit should be installed at the inside top of the tank.
You will also need (not included):
You can sandwich a trimmed (~50mm square) screen on both sides of the fan to prevent any critters from reaching the fan blades. The largest safe opening size for the screen is recommended to maximize airflow while keeping pets (and their limbs) from reaching the blades.
The 0.5" x 0.125" magnet must be expoxied in the cavity on the base. You should add a few drops of epoxy into the cavity, insert the magnet, then fill the remaining cavity with epoxy. Try to encapsulate the magnet if you can, but be careful not to add so much epoxy that you create a bulge in the center above the magnet. You can install the fan into the Wisp 50 mount and then the mount into the enclosure once the epoxy has set. Secure the Wisp 50 with the second magnet, which should be placed on the opposite side of the glass / plastic from the Wisp 50.
Be very careful with the magnets! You should first place the outer magnet on the glass. Bring the Wisp 50 up to make contact with the glass then slide it toward the outer magnet. Once they are linked, gently slide the Wisp 50 to the desired location. Allowing the magnets to snap from a distance away from the glass could result in cracking or shattering!
