Microbiological safety chamber series MC xx-2

Working principle

The chamber takes part of the air from the environment and returns it back purified through absolute exhaust filter, the rest is circulating inside the chamber.

Air enters in to the chamber from the front side, through front opening and through slots in the working segments. Below segments the fresh air from environment and recirculating air are mixed.

Furthermore, the air travels through the return channel in the upper negative pressure plenum and enters the overpressure hood. Part of the air (app. 30%) a fan pushes through exhaust filter quality H14 (EN 1822) back to environment (or is led by exhaust connection to a facility exhaust system), rest of the air (app.70%) fan pushes through filter placed above working area quality H14 (EN 1822) and through perforated distributor in to working area. Ratio of the exhaust and  inlet air is provided through the area ratio between exhaust filter and filter placed above the working area.

Distribution grid spreads air laminar over the working area and vertically directs it towards the working surface of the chamber. The laminar air flow takes away dust particles generated by material manipulation. An air curtain is formed on the front of the chamber, between the operator and the location of the dust, which separates the working space in the chamber from the surrounding area.
The air curtain protects the work area from possible external contamination and prevents airborne particles from flowing out of the work space.

Control

A visual touch screen is designed for visualization and more transparent management. It is located on the front of the chamber, next to the the user. Its basic task is system management, error display and service settings.
