Filter-fan-units in cleanrooms

More than just moving air

The demands on filter-fan-units in cleanroom technology are significant

Special rooms come with special demands. In cleanroom operation, this means clean air with a high air exchange rate, sufficient pressure, exact temperature and humidity control, and air quality that is always consistent. To achieve all this, powerful ventilation systems (filter-fan-units) are required.

Filter-fan-units are used to supply production and filling facilities with ultra-clean air. They are mainly employed in ceiling-mounted systems in clean rooms in chip factories, bottle filling or plastic mold-ing facilities, the pharmaceutical industry and microstructure technology. These applications need everything to work together perfectly with reliable and durable fans.

These units made up of filter technology and fan ensure the required recirculating air mode. They also prevent contamination in the air and damage or impairments when producing sensitive products. In addition, ebm‑papst FFUs are extremely quiet, satisfying the strict noise protection conditions for production in clean rooms.
