Requiring no liquid pressure, No Drip Siphon Fed Atomizing Spray Nozzles can be used with gravity fed liquids or lift liquids from siphon height up to 36 in. Nozzles positively seal off flow when compressed air supply is shut off, eliminating possibility of drips. Suitable for liquids with viscosity up to 200 cp, nozzles are available in round and flat fan patterns, and are designed for non-pressurized liquid applications that do not require independent air and liquid control.
