Persons air-shower air-lock AEROJETplus-P2

AufgabenstellungDas entering and leaving pure areas takes place generally over air-locks for persons. The air-lock for persons has thereby two important tasks. First of all it is the pure area from the contaminated ambient air effectively to separate and prevent that during entering persons contaminated air arrives into the pure area. Secondly it is to blow the particle off responsible at the work clothing of the personnel as effectively as possible. By the employment of the AEROJETplus-P2 can " both Aufgaben" to be successfully solved. BauartDie AEROJETplus-P2 consists of an air-lock module and a put on drive module. The modular structure of the air-lock module makes passage variants possible to the left/right/or straightforward. The doors are from full glass (safety glass 8mm thickly). The inspection side of the AEROJETplus-P2 is on the grey side. In the interior of the air-lock among themselves blowing nozzles are arranged to the air-lock center aligned are in all 4 corners. A lighting illuminates the interior. Two air cleaner cells of the filter class EU4 are in the ground range of the air-lock module and a mechanical filter of the filter class H13 are built in the drive module. Emergency stops tracers make a switching possible off by hand in the interior, on the grey side and the white side. Optionally the floor with sturdy gratings is laid out and can the doors down sealed werden.L�sungIn the AEROJETplus-P2 takes place an intensive incident airstream of the work clothing via highly pure air. Here the person is blown on approximately from head to foot. A radial fan sucks in the air, which is driven as circulating air, from lateral channels at the air-lock ground. The circulating air quantity amounts to 2,500 m3/h. Directly within the sucking in range contaminated air is pre-filtered of two air cleaner cells of the filter class EU4. Afterwards this air in branch canals is sucked upward in the drive module and after-filtered there of a mechanical filter of the filter class H13. Afterwards air arrives into the four hitting a corner channels of the air-lock module. Over the blowing nozzles air with high speed arrives again into the interior of the air-lock. There the air flow is from top to bottom arranged. Thus it is guaranteed that particles are in the interior of the air-lock or of the work clothes blown off on direct way downward sucked off will-function-will function those operation of the AEROJETplus-P2 are simply. The doors are mutually locked. In the ready condition the door is unlocked on the grey side and on the white side locked. Red and green lights indicate in the interior, on the grey side and the white side whether a door unlocked or locked is. Passage from the grey side to the white side: The person opens the door and enters the air-lock. With the opening of the door the fan begins to run. As soon as the door closed it automatically is locked. Now the blowing on phase for the person begins. The duration is by the factory programmed on 20 seconds and can be changed. At expiration of this time interval the door on the white side is unlocked and the person leaves the air-lock. After automatic closing of this door the air-lock changes again into the ready condition. The air-lock scolded not further used in such a way the fan after 90 seconds off. Passage from the white side to the grey side: The person stands first before a locked door (see ready condition). The right of way is requested by operation of the attention key and the fan is started. The door on the grey side is locked and afterwards the door on the white side is unlocked. The person opens the door and enters the air-lock. As soon as the door closed it automatically is locked. Afterwards the door on the grey side is unlocked and the person leaves the air-lock to the grey side. After automatic closing of this door the air-lock changes again into the ready condition. The air-lock scolded not further used in such a way the fan after 90 seconds off.
