Spraying a fine mist over a diameter of up to 7.2′, DIG’s small-droplet-size, low-precipitation-rate Micro Mist Sprayers are used for residential gardens, greenhouses and nurseries to water large planter boxes and flowerbeds, or for seed germination. They are available with a full-circle spray pattern only and in one model, 7750BB (pack of 5). The micro sprayers incorporate a vortex mechanism, allowing low water flow through a large water passage for 360° of fine mist spray in a flat trajectory. They may be placed upright or hung upside down where overhead misting is required.

The 7750BB Micro Mist Sprayers on 12/24 large threads spray a full-circle, fine-mist flat pattern to a maximum diameter of 7.2′ with a flow range of 5.3 to 7.4 GPH at 25 to 50 PSI. They are available in a one-piece construction that includes thread to connect into micro tubing, directly to the drip tubing, or to extend using a PE riser. Use the mist sprayers where overhead watering is suggested on any type of planting, including vegetation that requires moisture, flowerbeds, seed germination, in planter boxes and for large pots.
For complete coverage of an area, the recommended spacing is 3’ to 5’ between each micro spray head to a maximum distance of 99′ to 135’ in length using 1/2” drip tubing as the main lateral. Like micro sprinklers, these micro mist sprayers operate at low pressures and require a filter to protect the water passages of the sprayer. The main advantages of the micro mist sprayers are their small size, lack of moving parts and fine droplets, allowing them to fit in any area.
Micro sprayers are an efficient and reliable method for applying 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 them in windy areas as their small-sized droplets can be easily dispersed in the air, even under low-to-moderate wind conditions, adversely affecting uniformity. A main advantage of low-flow micro irrigation is that a relatively large number of micro sprayers can operate simultaneously with a small 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.
