A blower system for a gas turbine engine comprising: a rotor assembly, an airframe port and a routing-control valve. The rotor assembly is configured to be mechanically coupled to a spool of the gas turbine engine. The airframe port is configured to receive and discharge air to an airframe system. The routing-control valve comprises: a primary channel for bidirectional flow between the rotor assembly and the airframe port; a primary valve member configured to open and close the primary channel; and an auxiliary channel branched from the primary channel. The auxiliary channel is configured to bypass the primary valve member for: a first auxiliary flow from the airframe port to the rotor assembly; or a second auxiliary flow for purging air from the rotor assembly to a discharge port. The blower system is configured to operate in an engine drive mode and in a blower mode.
