Auto Clean PFC-50000 Pressurised Pond Filter For ponds up to 50,000 litres Please note: Our AUTO-PFC-50000 product is despatched on a 48 hour 2 day service due to the filter size. Our range of automatic PFC pressurised pond filters with built-in UV clarifiers are designed to be efficient self-cleaning units with the simple turn of a dial. Just like the manual PFC models, auto PFC filters are kept continually pressurised by your pond pump which will help you to maintain the best water quality for healthy pond fishkeeping. Pond filter cleaning with the auto PFC is easier than ever due to the motorised sponge cleaning system. Just turn the dial so that the blue arrow is pointing in the direction of the dirty water outlet; listen for the ‘beep’ indicating the start of the cleaning process and at the sound of the second ‘beep’, your PFC pond filter unit and sponges will be clean. Not only will this reduce the need for any manual labour but there is no need to disassemble any part of the unit except when replacing foams or performing a full system clean. Each automatic cleaning PFC pond filter is equipped with a built-in UV light, which helps prevent algae growth and eliminates micro-organisms in the pond water which can lead to fish diseases.
