The invention relates to a blower arrangement for gas. The blower arrangement comprises a blower with a blower housing, at least one gas-inlet opening formed in the blower housing and gas-outlet opening, and at least one rotary-driven blower wheel arranged in the blower housing. Furthermore, the blower arrangement has at least one silencer device with at least one gas guiding element, wherein the gas-guiding element comprises a plurality of silencer openings and is designed as a gas guiding pipe. The gas guiding pipe varies its cross section along its longitudinal extension and has a wall, which is designed to be wave-like along the longitudinal extension of the gas guiding pipe. The silencer device also comprises at least one silencer chamber, which is in flow connection with the silencer openings and is arranged at least in sections laterally behind the gas guiding element.
