How an automatic filter works
On large irrigation systems, cleaning filters by hand several times a day is a lot of work, and if it is forgotten the network pressure drops. An automatic filter, when clogging and the inlet–outlet pressure difference reach a set level, or on a set schedule, reverses the flow for a short time and sends the collected particles out through the flush outlet.
The flushing happens while irrigation continues, so the network stays clean without stopping or manual work. Automatic filters come in disc and screen types and are usually installed at the pump station of large orchards and farms.
Sizes and enquiry
Our rows cover automatic filters in 2, 3, 4, 6, 8, 10 and 12 inch. Our catalogue lists this product by size, type (disc or screen) and flow, and it is priced on enquiry.
In your enquiry give the total flow, working pressure, water source, inlet size and filter type. Agree the location, flush line and controller power supply with the system designer before buying.
Where an automatic filter fits in the station
In large filtration stations, the automatic filter usually follows a hydrocyclone or a sand filter. In sandy water the hydrocyclone removes heavy particles before they reach the automatic filter and cuts the number of flushes.
The flush line must lead dirty water to a place away from the station and the cropped land. Set the pressure difference and flushing schedule at commissioning according to the water quality, and review them in the first weeks.
If the station loses power, some models do not flush until it returns; ask about the controller type and power supply when buying.
