Cost Savings
Think how often you need to change your filter socks!
Do you wash them or change them, if so what is your time worth every 3-4 days?
Incredible but true, compare the cost of both options to yourself and you will realise why the ClariSea Fleece Filter is so popular.
It is not really correct to state a micron size for this type of filter material as it can lead to confusion.
Like all fleece filters of this type, including bag filters, the size of the particle removed by the media will continuously reduce as the fleece dirties.
Example; with a 200 micron filter sock, the largest particle that should pass through when new is 200 microns, however as the media starts to collect dirt, the holes get blocked creating smaller and smaller passages and so the bag collects out smaller and smaller particles. It continues to do this until the head pressure can no longer force water through the small holes and it overflows.
The ClariSea works in exactly the same way except that instead of overflowing and having to change or clean the bag, it automatically rolls on to expose a fresh piece of material. The fresh fleece will allow larger particles to pass through and the dirtier material will stop smaller particles.
The higher the flow rate through the fleece, the less time the roll will last.
Imagine it as a large group of people trying to leave a building through one door. The slower and more organised they try to leave, the easier it is for individuals to bunch together and to fill into small gaps in the crowd, like water and small particles finding their way through small holes in the fleece.
Compare this with people trying to leave quickly in a panic, and chaos is created, so that people back up around the door, like the water level backing up and triggering the float to move on the roll in the ClariSea without it becoming fully saturated with dirt.
