A clean room is a sterile or controlled environment, free from, or with a low level of, dust and other airborne contaminants.
Human beings are typically the largest single source of contamination in a clean room, so workers must follow special procedures on entry and exit, and wear special apparel to trap human hair, human skin flakes, pollen, mould, etc.
A clean room also presents challenges in communicating with the outside world, but a device known as a melaphone is specifically designed to facilitate the mutual exchange of information between the interior and exterior of a clean room, without compromising the sterility of the area. Essentially, a melaphone consists of a circular, transparent diaphragm, made of a tough, versatile plastic called polycarbonate and reinforced with a stainless-steel mesh. The transparent diaphragm transmits sound freely and clearly, without the need for a loudspeaker and/or power supply but, because air does not flow through it, it cannot transmit airborne contaminants.
Clear communication into your cleanroom
Diaphragms are available in diameters large and small, which can easily be accommodated in a range of clean room settings. Even in smaller diameters, they offer a high degree of vision, so that workers outside a clean room can see those inside, and vice versa, and work safely.
