Filter fan units (FFU) for safe room air technology

A cleanroom is characterised by the fact that a high degree of cleanliness is permanently guaranteed within its environment. Integrated filter fan units (FFU) make a significant contribution to increasing the particulate cleanliness in your local work area. With the help of the FFU, pure workspaces can be set up user-specifically and individually.

What is an FFU?

An FFU consists of a high-performance filter and an integrated fan. It draws in the air of the environment and releases filtered air in a defined clean quality. The highly pure filtered air is thus free of particles such as dust, bacteria, aerosols, germs or even pollen. The air flows through the cleanroom via a laminar flow with a corresponding air velocity and carries airborne particles with it. The air flow rate is specified in cubic metres per hour (m³/ h) and describes how many cubic metres of room air can be circulated per hour.

Areas of application of the FFU in the clean room

Schilling Engineering's FFUs are integrated into the ceiling of cleanrooms, cleanroom tents and CNC cleanrooms to save space. If the filters need to be serviced or replaced, easy access from below is possible. FFUs also ensure targeted cleanliness in our workplaces and enclosures. Each FFU from Schilling Engineering is equipped with a high-performance ULPA 15 filter, which precisely filters even the smallest particles from the ambient air with a separation efficiency of 99.9995 %.

Why a FFU?

With our clean air filters, you increase safety when manufacturing sensitive products or products in your clean room laboratory. Adapted to your requirements, absolute purity can be permanently guaranteed by the filter fan unit. With a central control system, you can operate the clean air filters and coordinate the general conditions required for you in your clean room.
