The VarioPress® Pro-E pressure filter series UV 55w boultin has a large filter package, cleaning is done by the electrically driven AUTO-CLEAN system, which starts when the cleaning lever is converted. With the VarioPress® Pro-E pressure filters (depending on type), ponds up to 75 m3 of content can be purified. The built-in UV-c lamp can be set to burning hours as desired with the built-in timer set to 24-12-0 hours.

The number of flushing intervals depends on the contamination of the pond
water.
Regular flushing of the pressure filter is very important, a too dirty pressure filter
can cause overpressure which can lead to leakage and damage. A pressure filter
that is too dirty will adversely affect the operation and automatic flushing and can
lead to additional wear and damage. When determining the cleaning intervals, the
rule is that the pressure filter should be able to rinse itself in about 2 minutes
(rinsing time), the rinse water should flow out of the filter clean again within
these 2 minutes. If dirty water still comes out of the drain line after about 2 min
of flushing, the number of flushing intervals will have to be increased.
Filtration advice
Take note that although each filtration system is rated for a specific pond literage, we calculate filtration differently in practice. Size matters, but what matters most is choosing a larger filter than the minimum. A bigger filter means you clean it far less often, and it protects the system itself from damage that comes from running it too close to capacity. For example, on a thirty thousand litre pond we would not recommend a thirty thousand litre filter. We would suggest a larger one, or even two filters together. Otherwise you end up cleaning every week or so. A larger setup gives you a hassle-free system, though of course it depends on your budget. We always tell our customers: bigger is better for easier maintenance and longer filter life.
