Hello, This is an important project for industrial use for our company. We would like to spray water on a surface of 2m long and 30cm width. We only want the Mist effect , and we want each time we put the water to have 1.5grams on all the surfaces. This is a project for industrial use with high value to us and we are able to pay high extra development cost to make it happen. We would like to buy 1000 units. Thanks Show More
