The requirements are stringent.
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. High-performance ventilation systems are required to achieve all that. ebm-papst has developed special fans for filter-fan-units (FFU) for cleanroom ceilings. 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 cleanrooms.
