Abstract

An exhaust air conduit for a pneumatically powered pump, in particular, from a coating agent pump in a painting plant, is provided. The conduit includes an inlet for receiving the exhaust air from the pump, an outlet for discharging the exhaust air, and an exhaust air channel in which the exhaust air flows from the inlet to the outlet of the exhaust air conduit, and a housing member in which the exhaust air channel extends. A first thermal insulation element is provided in the region of a direction change of the exhaust air channel, in order to prevent an accumulation of the exhaust air directly at the inner wall of the exhaust air channel and thereby to lessen the cooling of the housing member.
