DIG’s easy-to-install Fan Micro Sprayers, available in single unit packs and fully assembled with a 13” stake, 12” PE riser and 1/4″ barb, offer 360° (model 107-1B), 180° (model 108-1B) and 90° (model 109-1B) diameter full-circle spray patterns with a flow of 8.1 to 40.3 GPH at 25 PSI. They have reduced susceptibility to clogging due to larger sized orifices and can be installed in a wide range of applications. Used for residential gardens, flowerbeds, groundcovers, shrubs and trees, the micro sprayer are ideal for areas where low flow overhead irrigation is desired or for areas where drip emitters or conventional sprinkler systems are not practical.

The Fan Micro Sprayers are available with full-, half- and quarter-circle patterns and with a flow rate of 8.1 to 40.3 GPH at 25 PSI. Using a PE riser extension, the height of the sprayer can be adjusted to fit taller plants and higher vegetation growth. The higher the position of the micro sprayers above the ground, the larger the wetted area. These fan micro sprayers are available in a complete assembly with a 13” stake, 12” PE riser and 1/4” barb for added flexibility in the product installation. Use the micro sprayers when overhead watering is suggested on any type of planting, including vegetation that requires moisture, groundcovers, flowerbeds or individual trees along the poly tubing. The ideal spacing is three to five feet between the adjustable spray heads or one per tree to a maximum distance of 32′ to 80′ in length, depending on flow rate, using 1/2” drip tubing as the main lateral.
The micro sprayers are an efficient and reliable method to apply water. To cover densely planted areas, place the micro sprayers close together in rectangular or triangular spacing for good overlapping irrigation and better uniformity. Do not use the micro sprayers in windy areas as their small size droplets can be easily dispersed in the air, even under low to moderate wind conditions, adversely affecting uniformity. The main advantage of low flow micro irrigation is that a relatively large number of micro sprayers can operate simultaneously.
The micro irrigation systems consist of a system “head” assembly and distribution laterals. The system head assembly consists of a backflow device, filter, fertilizer injector (optional) and pressure regulator. Generally, the head assembly parts can be found in any store that carries drip irrigation components. The fertilizer applicator and AC or DC controllers are optional equipment but highly desirable because they can add flexibility to the system. The distribution laterals consist of main line pipes, usually made of PVC, the sub lateral pipes, made of polyethylene (PE), fittings and accessories. The system can be automated electronically by adding an AC controller connected to an AC solenoid valve, a hose end timer or a battery operated controller.
Basic installation recommendations for this product include first reviewing the area and then making a drawing of the garden or site with your preferred layout.
If automation is required, use one of DIG’s hose end timers or battery operated controllers. The ideal controller should have flexible scheduling and two to four start times per day for added flexibility.
