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.
Pattern guide A = hollow cone B = solid cone W = all purpose
See pattern description above for usage information
Substitute () in P/N with pattern letter to completely specify individual nozzle, e.g. 6560W.
Type .579 MH mobile home nozzles are low capacity nozzles designed for mobile home use. This design will minimize the usual plugging problems associated with low flow rates.
