The filter screens are readily accessible for easy removal and cleaning. This line of filters includes a manual flush cap for easy flushing or removal of particles trapped in the bottom of the filter.

Screen filters are the most common filters used in the irrigation industry and in most cases the least expensive. They are generally used as a backup for any type of drip irrigation installation and are mainly installed where the quality of water is good. Screen filters are excellent for removing hard particulates from water, such as sand and other small elements often found in city water. The screen filters are not suitable for removing organic materials such as algae, mold and slime. These non-solid materials tend to embed themselves into the screen material where they are very difficult to remove. In other cases they simply slide through the holes in the screen by temporarily deforming their shape. Screen filters are cleaned by removing cover and hand cleaning the screen.

Installation for 1 1/2" and 2" MNPT Filter


Almost any water sources can be made suitable for use in drip irrigation by means of appropriate physical and/or chemical treatment. Physical treatment is the removal of organic suspended solids which are large enough to block the drip emitter outlets. Suspended solids may be removed by means of a separator, screen filter, disk filter, or some combination of the above. Where waters containing substantial solid, such as sand and other small elements without adequate a treatment, clogging will usually take place, leading to uneven water distribution and poor system performance or drip emitters uniformity.Chemical treatment can be an option with the addition of one or more chemicals to the water supply for the purpose of controlling biological growths. In agriculture and in crop production chemical treatment may be used alone or in conjunction with some type of filters. Chemical treatments used in micro irrigation systems include the addition of chlorine and /or acid in very low percentage to the water supply.


The various water quality encountered in operating drip irrigation systems are listed below. In some situations, two or more of these problems may be existing suggesting much complex treatment and procedures may be required.

  1. Existence of large organic particles in the water supply.
  2. Existence of high silt in the water supply.
  3. Existence of rocks and sand in the water supply.
  4. Growth of bacterial in the system.
  5. Growth of algae within the water supply or the system.

Filtration recommendation:

  • Well or potable water: 150 to 155 mesh filter on the main line or with backup filter after the electric remote control valve to the laterals
  • Water with sand: disc filter on the main line after the back flow device
  • Reclaim water: disc filter model followed by screen filter model with 155 mesh

Filter Installation

  • Make sure the main filter is installed in an easily accessible location after the back-flow device with space to removed the screen or discs elements for periodic cleaning
  • The Screen filters and disc filters need to be flushed after installation is complete.
