Overview

The Mister™ is designed for low volume misting applications, including propagation. Its built-in check valve prevents draining immediately after each irrigation session. It also provides consistent system start-up – delivering an instantaneous, highly uniform distribution that makes the Mister sprinkler ideal for short-cycle applications in misting systems.

Riser Stake

The Riser Stake is now available in either 26” or 14” length models. It can be used for direct mounting a barbed base Micro-Sprinkler into 0.25”, 0.270”, or 8 mm tubing, or for use with a ½” M NPT connection Micro-Sprinkler or spray nozzle.

For best results, the Riser Stake should be installed at least 1/3 its length into the ground.

Drop Assembly

The Senninger Drop Assembly offers simple, fast and economical installation of inverted Micro-Sprinklers. It comes in overall lengths of 3, 4 or 6 ft (0.91, 1.22 or 1.83 m).

Pressure Regulators

Senninger® pressure regulators control excessive and varying inlet pressures to a constant outlet pressure. They allow a system to maintain an accurate flow output at each sprinkler head to ensure proper distribution uniformity.

Recognizing the importance of maintaining correct system pressure and uniform distribution, Senninger offers various models to meet specific flow and installation requirements.
