Delavan 38745-1 DA-1.5 Air Atomizing Siphon Oil Nozzle For Waste Oil And Heavy Oil Applications Specifications 8.0 psi air Lift height of 0.50”. Flow is approximately 1.465 gph With an 80° spray angle The DA Nozzles are of a similar design as the SNA but are developped to burn oils with very high viscosity . Spray Characteristics • Produces a solid cone spray pattern with extremely fine particle size at low air pressures and low CFM. • Flow rates, spray angles and droplet sizes can be modified, with limitations, by variations in air, lift, etc. • Clog free operation of low volume due to relatively large passages.
