H5070A

Hollow-cone Type A nozzles are mainly used on burners with a hollow cone air pattern and for through-puts up to 2 GPH. The droplet distribution is concentrated on the outside of the cone and results in good ignition and low-noise combustion. Solid-cone Type B nozzles produce a spray that distributes droplets fairly uniformly throughout the complete pattern. The spray pattern becomes progressively more hollow at higher flow rates, particularly above 8 GPH. Provides smooth ignition and efficient combustion, particularly in large burners.
Type W all purpose nozzles are neither truly hollow nor solid. These nozzles frequently can be used in place of either solid or hollow cone nozzles between 0.40 and 8 GPH, regardless of the burner’s air pattern. The lower flow rates tend to be more solid.
