What a disc filter is and why drip needs one
Drippers and drip tape have very fine passages, and sand, silt and algae quickly clog them. A disc filter, with a stack of grooved plastic discs pressed together, removes these particles before they enter the network. Water passes between the grooves and the particles stay outside.
To clean a manual disc filter, the cover is opened and the discs are separated and rinsed with water. Compared with a screen filter, a disc filter holds organic matter and algae better and is common with well and pond water.
Disc filter size and mesh
Our rows cover disc filters in 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3 and 4 inch. Our catalogue names mesh 80 to 200 for this filter; a higher mesh catches finer particles. The right mesh is given by the dripper or drip tape maker.
The filter size is chosen by the total flow of an irrigation block, not just the pipe diameter; an undersized filter causes a large pressure loss. In your enquiry give the flow, water source (well, pond or river), inlet size and mesh.
Maintaining and cleaning a disc filter
Pressure gauges before and after the filter show when cleaning is due; when the pressure difference rises above its clean value, open the filter and wash the discs. Separate the discs and wash the sediment out of the grooves with a water jet.
Check the cover O-ring each time you open the filter and replace it if damaged so it does not leak.

Manual Disc Filter — FAQ
Disc or screen filter?
A disc filter holds organic matter and algae better; a screen filter is simpler for mineral particles and fairly clean water.
What does mesh mean?
Openings per inch; a higher mesh catches finer particles.
Which sizes are supplied?
From 3/4 to 4 inch.
How is filter size chosen?
By the block flow; the designer or seller recommends it from the flow.
