If a product or substance is processed that is potentially hazardous, microbiological safety boxes according to EN 12469 are used. Potentially hazardous materials or activities include the processing of blood, biological samples, chemicals, tissues, cells, etc. A microbiological safety box is also known as a biohazard. Compared to the classical laminar box, it protects not only the actual material being processed but also the surroundings from its possible influence. All the air that comes out of the working area of the plant passes through a high-efficiency exhaust filter. As with the laminar box, noise, vibration, operating costs, and other parameters are dependent on the quality and sizing of the technical and work area, the high-efficiency filter, the fan, and the control system. The EN 12469 standard divides the boxes into three categories (A, B, C) according to their efficiency in terms of tightness, cleanability and sterilizability. The MBB microbiological box and the MBB-IVF received the highest marks in all categories. This is mainly due to the perfect design and innovative solutions. Technological highlights include, for example, the windscreen control, which ensures safe working, the possibility of inserting large objects into the working area and the safe cleaning of the complete glass surface.

Special types for work environment protection are devices covering larger areas, e.g. covering process lines. The modular FBB-Portal system is used for this purpose. In many cases, this solution is more economically advantageous than the implementation of a classic cleanroom. The size of the working area and space is decided according to the need. A combination of laminar and turbulent flow is often used in these installations.

Nowadays, it is highly advisable to use a modern control system for these critical devices, such as the CR2000 used in our facilities. The modern control system should ensure autonomous setting and monitoring of operating parameters, warning of malfunctions, timely notification of impending non-compliant conditions such as the impending need to replace filters, etc. In terms of full control of the plant and minimising downtime, today's plants should have remote access capability. This allows both remote control and remote servicing. The advantages of using today's modern technology include the possibility of flexible response to new requirements of supervisory authorities, quality management and, of course, the addition of new functions that increase productivity and simplify operation. These requirements are addressed by the ability to update firmware. This is one of the most important conditions for ensuring sustainability, alongside the use of quality technology, quality materials, quality construction and a responsible business policy, and our equipment fully meets these conditions. As a manufacturer, we guarantee service support for the entire lifetime of the equipment. Certainly this approach means higher investment costs, but thanks to low operating costs and a long technical and technological lifetime, it is among the most economically advantageous.
