How to make a Water Mister
This document describes how to build a vortex style water mister.
Required Tools for Assembly
- Tape Measure
- 16 penny nail, screw, or other such sharp object
- Utility knife (sharp!)
- Heat gun
Required Parts for Assembly
- 10’ of 5/32” polyurethane airline
- 10’ of 1/4” polyethylene airline
- One way check valve push-on 1/4"
- Barbed Union 3/32”
- 4” of 3/8” shrink tube
- 2-Way or 3-Way Solenoid Valve
- PicoBoo or BooBox Controller
- Motion Sensor, Step mat, or hand trigger
LET’S BUILD IT!
We suggest that you read through all steps before beginning.
Cut 10’ of 5/32” airline and 10’ of 1/4” polyethylene airline
Insert the check valve onto the 1/4" polyethylene airline as shown. Make sure the pink side is oriented as shown.
Cut off about 9” of 1/4” polyethylene airline and insert into the other end of the check valve.
Snip or cut off the square sides of the barbed union. We use wire snips as shown but you could also use a sharp utility knife.
Shown is the barbed union with square sides partially removed
Shown is the barbed union with square sides completely removed.
Push one end of the barbed union into the 5/32” airline. It helps to heat up the airline a bit with a heat gun first.
Use a sharp utility knife to cut one end of the barbed union at an angle as shown.
Use a nail to punch a hole at the angle shown exactly 2” from the end of the 9” polyethylene airline. The more of an angle (hole parallel to the airline) the better. If you do not get sufficient mist then the angle will need to be increased.
Push the barbed union into the hole at an angle with the cut angle positioned as shown. It is very important that the cut angle on the barbed fitting is pointing upwards. If when testing the mist is not sufficient then the angle is not pointed upwards.
Here it is fully inserted.
Take a 4” piece of shrink tube and slide it over the assembly and shrink using a heat gun. You can optionally wrap in electrical tape if you do not have shrink tube and a heat gun.
Here is the completed assembly. Water will mist out of the end shown.
Using the Water Sprayer
Insert the free end of the 5/32” airline into a bucket of clean water.
Water will mist from the assembly end when you supply air to the free end of the 1/4" polyethylene airline.
To automate you can insert a 2-way or 3-way solenoid to the free end of the 1/4" polyethylene airline and control with one of our PicoBoo or BooBox controllers.
