Abstract: A device for capturing air from fluids in piping and for rendering noiseless the flow of fluids in piping. The device comprises an elongated body which is connected to the piping through inlet and outlet openings. The inlet opening is directed transversely to the flow of fluids within the elongated body, so that the fluids introduced into the body is vigorously agitated and bubbled for the effective capture of air contained in the fluids.
