DIG’s Adjustable Spray Pattern Micro Sprayers incorporate a vortex mechanism that offers an unusual configuration of a large water passage, a 360° spray pattern and an adjustable cap combined with a 6” stake and 1/4” barb. Available with a full-circle pattern only, these micro sprayers have an adjustable flow feature from 0 to 18 GPH and a diameter from 0 to 10’ at 25 PSI. The available models include 410B with a pack of 3, 410PRO with a pack of 25, and ASD-1B with a pack of 1. The micro sprayers have an adjustable cap that allows for simultaneous control of the flow rate and the wetting area. Used in residential gardens for planter boxes, large pots, flowerbeds, groundcovers, shrubs and trees, the low-precipitation-rate adjustable micro sprayers offer a convenient way to water areas where drip emitters or conventional sprinkler systems are not workable.

The 410 Adjustable Micro Sprayers are available with a full-circle spray pattern and a rotating cap that allows adjustment of the flow from 0 to 20 GPH at 30 PSI using approximately 14 clicks to full flow and diameter. The notch action between the adjustable cap and the base allows a decrease or increase of the wetting area from 0 to 11.5’. Each micro sprayer comes in a one-piece construction that includes a 6” stake with a barb, rotating cap and an additional 1/4” barb to connect the micro tubing to the drip tubing. Use these micro sprayers where overhead watering is suggested on any type of planting, including vegetation that requires moisture, groundcovers, flowerbeds, individual trees along the poly tubing or for planter boxes and large pots.
For complete coverage of an area, the recommended spacing is 4’ to 5’ between each spray head or one per tree to a maximum distance of 128’ in length when the flow cap is completely open, using 1/2” drip tubing as the main lateral. Like micro sprinklers, these micro sprayers operate at low pressure and require a filter to protect the small orifice of the adjustable sprayer from clogging. The main advantages of the adjustable micro sprayers are a small size that can fit in most areas, lack of moving parts and the capability to adjust the flow and change the wetting area.
Micro sprayers offer 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 the their small-sized 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 with a small size pipe.
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.
Start the installation from a PVC pipe or to pipe thread
