Microbiological safety chamber – MC NC

Working principle

The chamber takes the air from the surrounding and through an absolute outlet filter, purified air is sent out.

Part of the air (approx. 70%) enters the protective chamber from the upper side by a fan, the absolute filter of quality H14 (EN 1822) and the distribution grids. The remaining part (approximately 30%) of the air enters from the front through the open lifting glass thus providing a protective air curtain that prevents contamination from the outside. The air passes through:

• inlet filters of quality H14 (EN 1822), which are installed under working segments at the base of the chamber
• additional filter ("police filter") quality H14 (EN 1822), in the drainage channel - OPTION

The outlet is further connected to an air extraction system that is synchronized with the supply fan of the chamber and provides 100% air outlet to the environment, and in any case prevents the release of the substances from the chamber's workplace into the room. The drainage must also be synchronized by ventilating the space in which the chamber is located. Distribution grid laminarally distributes air 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. Filters under working segments are exchanged within the operating range when the chamber works. Properly packed them inside the working area in safe packaging. Access to these filters is easy and safe without risk to service personnel, possible contamination of the environment and the environment. The chamber is intended primarily for working with dangerous, risky groups of microorganisms, substances that are very dangerous for the operator and the environment and do not allow recirculation of the air inside the chamber.

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 user. Its basic task is system management, error display and service settings.
