Abstract: The invention relates to a compressor apparatus comprising a screw compressor (3) capable of producing a compressed air-oil mixture; a compressor outlet (13); an oil separator (11) to which the compressed air-oil mixture is transferable and by means of which a compressed air and an oil from the compressed air-oil mixture are separable from each other and the compressed air is dischargable at the compressor outlet (13); an oil diversion duct (15), which connects the oil separator (11) to the screw compressor (3), wherein the oil diversion duct comprises a fan device (19) at an oil cooler (17); and a controller (21), by means of which a speed (n) of the fan (19) and thus also the cooling of the oil at the oil cooler (17) is adjustable.

Abstract: A filter medium has a woven fabric (1) made from mineral yarns that is in turn covered with polymeric staple fibres (2) by needling. Optionally, a diaphragm (3) made from porous polytetrafluoroethylene is applied at least on one side of the filter medium, in particular on its inflow side.

Abstract: A safety circuit for protecting against an inadvertent operation activation of a pneumatic drive of an automatic assembling machine has at least one vertical cylinder (1) and one horizontal cylinder (2), each being controlled by one of first and second multi-way valves (3, 4) and fed by a primary pneumatic circuit. Two further pneumatic control circuits (8,9) are included in the automatic assembling machine that are automatically switch into and out of the primary pneumatic circuit, wherein the at least one vertical cylinder (1) and the at least one horizontal cylinder (2), after the “switching into”, either remains in its current position or moves to a rest position. Opened and closed switching of a pneumatic primary circuit is caused according to an activated mode-of-operation set by a system control (SPS) of the automatic assembling machine.
