Netafim MegaNet Filter, Replacement Internal Filter for MegaNet Sprinklers

Netafim MegaNet Filter, Part 63620-004400

MegaNet sprinklers throw water from small nozzles, and small nozzles clog easily. Netafim gives every MegaNet its own internal filter to protect that opening. This part is that filter, listed by Netafim as 63620-004400. It sits inside the upper body of the sprinkler, upstream of the nozzle. Grit, scale and organic debris stop at the filter instead of lodging in the orifice. That keeps the spray pattern even and the flow close to its rated value. The MegaNet runs at 29 to 45 psi at the head, with seven nozzle flows. Those flows run from 0.88 GPM on the yellow nozzle to 3.30 GPM on the red. A blocked filter shows up as a sprinkler that stops emitting water or sprays weakly. Netafim is clear that a MegaNet should never operate without its filter. A lost or torn filter is worth replacing before the sprinkler goes back into service.

Servicing Netafim Filter Parts in a MegaNet

Shut off the water and relieve pressure in the lateral before opening a sprinkler. Unscrew the upper body from the base. Pull the filter down to detach it from the upper body. Rinse it from the inside out with a water jet or compressed air. Inspect the filter body for tears, cracks or a warped seat. Fit a new filter if the old one is damaged or missing. Push the filter back into place and screw the upper body onto the base. Restore pressure and confirm a full, even spray. Clean the filters before each growing season and whenever flow drops. Upstream, Netafim recommends 40 mesh main filtration for lake or river water. Install a hydrocyclone ahead of the main filter where sand exceeds 2 ppm.
