| The special clamp system allows the fan unit and sealing canvas to be installed tightly in windows or doors with just a few simple hand movements, even in difficult installation situations. If the door frame is still missing, the sealing canvas is simply attached to the optionally available installation frame. Negative and positive pressure measurements can then be carried out directly one after the other in a time-saving manner without having to change the measuring arrangement, because the fan automatically changes the direction of movement. The system is controlled via the Wöhler BC 600 app, which you can download free of charge to your smartphone or tablet (Android, iOS, Windows). You only have to carry your mobile device instead of a heavy, wired control unit. All measurement data is then transferred there via WLAN. The measurement sequences specified in the relevant standards EN ISO 9972 and EN 13829 are stored in the app, so that the Wöhler BC 600 can carry out the standard-compliant measurement fully automatically and a fast and correct measurement process is ensured. Manual operation is still possible at any time if required. After a change in the measuring standard, the user only has to update the app, so that the conformity of the measurements to the standard is guaranteed in the long run. If only a leakage search is to be carried out, no control device is required. The Wöhler BC 600 regulates independently to the desired differential pressure. The actual status is then signalled by the lighting of the push buttons. |
