The utility model provides an integrated air track assembly that has filter, includes pressure connection, gives vent to anger and connects and the air track body, the air track body includes air track, down air track, filter and natural gas injection, the pressure connection of filter UNICOM, goes up the pressure stabilizing cavity, in natural gas injection UNICOM pressure stabilizing cavity, pressure stabilizing cavity down, and the lower natural gas injection of pressure stabilizing cavity UNICOM, joints of giving vent to anger, and natural gas injection's quantity is two at least, and the kind is deciding two kinds lifts, change lifts. This designs, and not only the filter effect is better, can accurate control natural gas flow, and assembly efficiency is higher, can promote the life of air track assembly, and integrated nature is strong moreover, occupation space is less, the steady voltage effect is strong, manufacturing cost is lower.
