ParlaRoller Gravity Filters

Filters that clean the water by allowing gravity to pull it through filter media.

If the media in the filtration bay becomes too clogged, the water level rises and the float sensor triggers a high power geared motor housed within a low-profile filtration roll to run and advance the media so new media is exposed to the water flow. The old media and the waste caught up in it is rolled up out of the water onto an easily disposable waste roll.

Once it is time to remove the spent media, It is as convenient as removing a single nylon bolt and sliding out all the electronics needed for the ParlaRoller to operate. The spent media roll slides off the motor casing for easy disposal. Slide a newly 3D-printed spent media roll, attach the fresh media and you're ready to filter! See the video for a demonstration on media changing.

Constructed out of PVC, Nylon, PETG, and TPU with electrical components, these filters balance simplicity with function. Once the Motor and controller is removed, (one nylon bolt) the whole filter can be soaked to clean.
