10-micron wool felt. Center core bonded to prevent media migration.
Produce a spray that distributes droplets fairly uniformly throughout the complete pattern. The spray pattern becomes progressively more hollow at higher flow rates. Provides smooth ignition and efficient combustion, particularly in larger burners.
Mainly used on burners with a hollow cone air pattern and for throughputs up to 2.00 GPH. The droplet distribution is concentrated on the outside of the cone and results in good ignition and low-noise combustion.
Brass with stainless inserts with sintered filter.
Neither truly a hollow or solid nozzle. The nozzles frequently can be used in place of either solid or hollow cone nozzles between 0.40 and 8.00 GPH, regardless of the burner's air pattern. The lower flow rates tend to be more hollow. Higher flow rates tend to be more solid.
