Commonly used for “C” and “D” classes of cleanliness where the direction of airflow is not clearly defined. The air flows in an irregular direction from the air supply inlet to the air outlet through cylindrical HEPA filters H14 at a filtering efficiency of 99.995%. The rate of air exchanges of clean air into the chamber usually ranges from 5 to 40 exchanges per hour.
The HVAC system allows for the formation of negative pressure in the interior of the isolator. This function is mostly used in case of a failure – compromised leak-proofness - and helps to protect personnel.
Another level of protection for critical points in the process is the creation of a pressure cascade so that the location of dangerous substance handling contains the highest level of negative pressure. This minimizes the risk of contaminating other chambers or the surroundings.
In order to prevent damage to the equipment caused by insufficient pressure a pneumatic valve is used. This protective function prevents the pressure from dropping further, thus protecting the technology from damage.
A beacon light and an acoustic alarm providing a quick audible and visual assessment of operational and failure states for the user.
The door allows for material transfer from the chamber to the surroundings or from the chamber to other equipment (e.g. a fume hood). The hinged door is operated with the help of a door latching mechanism. The door is made from AISI 316L stainless steel, safety glass, and silicone sealant.
This tri-clamp is necessary for validation and a periodic re-validation process. Can be used as an input for sensors or other devices.
Tri-clamp connection for an optional connection to the building waste pipe system or to add a collecting container.
Inflatable sealing, safety glass fitted with sleeved flanges. Sensors for monitoring safe window closure. A gas spring assists with easy opening.
The foot-operated switch acts to control a sliding port between chambers. After material-transfer the port can be closed with the foot switch and there is no need to remove hands from the sleeves.
The door allows material transfer between chambers. It is operated with a foot switch or with a control touch display. Door action is performed by a pneumatic valve. The door is fitted with inflatable sealing.
For improved ergonomics and easy transfer of material, the airlock is fitted with a sliding tray.
Easy cleaning of the isolator is made possible with an installed spray gun. It operates with two media and is controlled by a valve via the HMI panel. For washing, the chamber is connected to water piping and dried by switching over to compressed air.
Optional integration of a weighing platform in the isolator —A solid stable shelf made from thick sheet metal provides a base for installation of a weighing device.
Highly efficient H14 filters remove ultra-fine impurities from the air in the inlet and the outlet.
Rounded corners and highly polished surfaces allow for easy cleaning of the chamber. The chambers are precision-welded which guarantees their leak tightness.
Tri clamp equipped for a continuous liner.
Optional mounting of a continuous liner for material removal. A continuous liner is used to transfer material out of the chamber without contaminating the operator. There is a swivel-closing mechanism inside the chamber. A tube projects outside the chamber protected by a tubular foil and is used for removal of material.
This isolator control system is operated with a Siemens color touch screen. The Simatic control system from Siemens together with a foot-operated switch creates an intuitive and user-friendly experience. The screen displays the actual parameters of the environment and monitors emergency statuses. The system includes remote access for customer service support. As required, it is possible to implement connection to an additional device for production data storage and export.
