Design features and benefits of 3065 North American aspirators and gas mixers
3065 Aspirator Mixers are used to create a uniform air / fuel mixture to feed premix burner nozzles. Energy from blower air passing through the 3065 venturi creates suction, which entrains a proportional flow of gas at atmospheric (zero gauge) pressure. Multiple premix burner nozzles fed by a 3065 can be controlled by a single manual or motorized air valve.
Proper air/fuel ratio is initially set by adjusting the integral V-port* valve built into the mixer. The ratio is maintained from high fire to low by an “atmospheric regulator” (zero governor) or by cross connecting the regulator (e.g., North American’s 7218).
For coke oven, manufactured, and other gases corrosive to brass, specify 3065- -K Mixer with iron/steel parts in place of brass.
For an observation port in place of a -0 plug (no rod) specify 3065- -0-OBS (3065-1 to -8 sizes).
