Abstract
A method of and installation for supplying suction/compressed air and drying air to a printing machine, whereby the vacuum pumps and compressors which are necessary for supplying the suction air/compressed air are disposed together in a room with a separate air supply, wherein to homogenize if required condition air without extra costs the cooling air for the vacuum pumps or compressors is conducted substantially in a circuit, and the heated exhaust air of the vacuum pumps and the heated cooling air of the vacuum pumps and compressors are cooled in a heat exchanger and used for heating separate drying air.
