Price will be the cost of each unit plus shipping. For more detailed info and pics. https://www.backyardchickens.com/web/viewblog.php?id=97667-water-fogger-system I live in an area with many commercial chicken farms. I can buy these parts for a bit more than the farmers. I thought i would offer them to byc members. These foggers are used in commercial chicken houses to spray a fine mist onto the birds or area to keep them cool. These units can be used to cool animals, humans, even spray a fine mist on plants! They work on standard home water supply with no need for secondary regulation with 1/2 inch pvc pipe. Shipping and handling is $7.00 for up to 10 units and $14.00 for 11 to 30 units (usps priority with tracking number). minimum order 6 units, max order is 30 units. I will only ship to the lower 48 states.
