AL Delavan air atomising nozzle

AL Delavan air atomising nozzle series offers the user a wide selection of spray patterns, flow rates, and atomization patterns. Unlike hydraulic or pressure nozzles, which use the energy of fluid pressure to atomize, AL Series nozzles utilize the energy of compressed gas (usually air) to atomize the fluid. This allows for lower fluid pressure while still achieving a fine atomization. This is also beneficial for abrasive or high-viscosity fluids.

Construction and Materials

• Standard materials of construction are 316 stainless steel and ENP brass.
• The seals between the contact surfaces are PTFE, and the O-ring seals are Viton. Other materials can be supplied upon request.
• Standard inlet connections are 1/8 '94 BSPP and 1/4 '94 BSPP, with other sizes available upon request.
