Adjusting the drum.
The drum is equipped with a valve that permits you to control the rotation
speed of the drum. The valve is controlled by a small blue lever that’s
located on the water piston. A
slow
rotation speed is to be needed.
For optimum results as it also permits more time for the screen to be
washed while maximizing filter cake filtration on the drum screen. This
permits the removal of finer particles from the water column. A cleaning
cycle only takes approx. a quarter of the drum and
no more
.
The rest of the inner drum will clog some more as we need for finer
filtrating the smaller parts.
So standard it starts at 60 micron and stops at the end about 10 microns.
If you speed up the drum this will raise but never make more than half a
drum for security reasons.
At the end it is so fine that 10 micron dirt even will not pass anymore and
when you swipe you only see clouds and no debris so in this way the RDF
filter can go down to even ten microns without any extra pump resistance.
This makes the RDF filter unique (patented) and also it can be used in
swimming pools
Swimming pools
In a 30.000 gallon swimming pool we can make it work with a regulated rpm
BLUE-ECO pump of max 240 watt. In praxis already 150 watt max will do.
So less noise, less power, less money, more green.
In the wintertime we even go down to 20 watt or lower to have a constant
flow of the water. Also by night in the high season. Never switch it of but let
it run on 30 percent of your power. This will upraise your quality of the water.
