AutoPot™ Golf Filter is a 6 mm filter and is used for 30 L & 47 L Tanks.
It is simply placed inside of the tank once the 6 mm pipe is pushed through the 6 mm Top Hat Grommet at the bottom of the tank. It could be easily mounted. If it becomes detached from the tube, it will just float to the top of the water.
To avoid this make sure that it is pushed firmly into the tube. Available as Golf Filter case and filter material separately.
