Abstract: A compressed air servicing device comprises several device modules (3) arranged in a row direction (2) and connected detachably with each other. At least two device modules (3) are detachably connected together by a module connector (4) placed between them, the module connector (4) having a through opening (14) by way of which the two device modules (3) are connected for fluid flow with one another. The module connector (4) is fitted with at least one sensor (15) connected with the through opening (14), such sensor (15) making possible monitoring of status data with respect to the flowing compressed air.

Abstract: A soft start device for compressed air systems comprises a primary inlet at which compressed air at a primary pressure may be supplied, the primary inlet being connected with a secondary outlet able to be coupled with a load, by a valve circuit, at which compressed air is taken at the secondary pressure lower than or equal to the primary pressure, a principal valve placed between the primary and secondary outlet, said principal valve being able to be shunted by a bypass, a choke device being placed in the bypass, the principal valve and the choke device together with further valves of the valve circuit being connected together in a circuit and the valve circuit placed in a standard venting switching setting that the secondary outlet is vented.

Abstract: A vacuum handling device comprises includes a vacuum source having a suction nozzle means (6) operating on the ejector principle and furthermore a suction gripper (3) which possesses a gripper part (26) connected with the suction side of the suction nozzle (6). The housing of the vacuum source (2) and of the suction gripper (3) constitute a housing unit (4), the gripper part (26) being adjustably mounted on the housing unit (4) for setting in the acting suction direction (44) thereof.

Abstract: A vacuum producing device (1) possessing a principal suction nozzle unit (2) with a shut off valve (27) on the upstream side thereof and an additional suction nozzle unit (3) connected in parallel to the principal suction nozzle unit (2). While the supply of pressure medium for the principal suction nozzle unit (2) is controlled in a manner dependent on the negative pressure produced by controlling the shut off valve (27), the additional suction nozzle unit (3) remains (3) constantly in operation. This means that a complete build up of vacuum may be ensured in conjunction with a complete switching off of the principal suction nozzle unit (2) together with a resulting air economizing effect.

Abstract: A filter device for filtering compressed air having recognition means (24), which render possible recognition of the degree of contamination of the filter means (6) fitted. The recognition means (24) comprise a pressure differential sensor means (25) responsive to the pressure differential at the filter means (6) and a flow rate sensor means (26) responsive to the flow rate. Furthermore there is an electronic evaluating means (27) for linking the detected pressure differential values and the flow rate values to give a condition value relevant for the degree of contamination of the filter means (6) and to be compared with predetermined threshold values.

Abstract: A filter device for the filtration of compressed air, which is provided with a filter means (6) able to be deinstalled for cleaning and/or renewal purposes. Furthermore there is a detection means (52) which renders possible detection of the filter means (6) and which is able to produce an electrical detect signal dependent on the result of a detection operation, such signal being able to be employed for suitable purposes.
