CLEAN AIR à AIR CURTAIN

A useful device for clean room application, it help a person to communicate and see another person standing in clean room thus avoiding any contamination. Mechanical see-through device works on the principle of sound vibrations. When a person stands near the voice communicator & talks through it to another person on other side, the see-through-membrane (transparent membrane) of the voice communicator vibrates & transfer the sound to the other person & he can easily hear the voice. He can also see the person with whom he is talking. It can be used from both sides. A buzzer can optionally be installed to signal to the person in the clean room to whom one has to talk or vice versa. It is very compact & aesthetically designed device and is economically priced.
