How a screen filter works
A screen filter has a cylindrical screen that water passes through, while particles larger than the screen openings stay behind. It suits mineral particles such as fine sand in fairly clean water and is usually fitted after a hydrocyclone or as a second filter after a sand filter.
Cleaning is simple: the cover is opened and the screen is taken out and rinsed. A polymer body is light and cheap, and a metal body is used for larger sizes and higher pressures.
Sizes and choosing
Our rows cover screen filters in 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3, 4 and 6 inch. The size is chosen by the total line flow and the mesh is set by the dripper or drip tape maker.
In your enquiry give the size, body material (polymer or metal), mesh, flow and water source. If your water carries a lot of algae or organic matter, consider a disc filter or a sand filter as well.
Maintaining and positioning a screen filter
Fit the screen filter where the cover is easy to open and the screen easy to remove, with pressure gauges before and after it. When the pressure difference rises, take the screen out and wash it with a soft brush and water.
Replace a damaged or holed screen at once, because even a small hole lets particles reach the drippers. Check the cover O-ring each time you clean it as well.
In stations with several filters in series, the screen filter is usually the last stage and catches the fine particles that pass the earlier filters.
