Filter fan units (FFU) & cleanroom filters
Filter fan units (FFU) make a significant contribution to increasing the particulate purity in your local work area. With the help of the FFU at Cleanroom, clean working areas can be set up individually for specific users. Our ULPA 15 filter fan units are energy-saving and quiet in operation. Suitable replacement filters can be obtained from us and easily replaced.
We would be happy to look at your entire process together and supply you with the right FFUs, perfect for your cleanroom process. Our replacement filters are designed for most common FFUs, please contact us.

Filter fan units - at a glance
ULPA 15 high-performance filter
All of the FFUs we offer are equipped with ULPA15 high-performance filters, which offer an extremely high level of safety and availability.
Separation efficiency > 99.9995 %
The high-performance filters have a separation efficiency of over 99.9995%
Variable air speed
The outflow speed of the laminar flow can be infinitely adjusted using a manual speed controller or a variphase control.
Energy-saving design
The FFU type SGE-EC has a lower energy consumption than comparable FFUs. Reduce your operating costs and your CO2 emissions.
Easy integration into existing cleanroom modules
All our replacement filters can be integrated into the standard filter fan units (e.g. ENVIRCO MAC19). Please ask us if you are not sure about your existing modules, integration is usually possible without any problems.
Very quiet operation
The ULPA15 high-performance MAC10 filters are equipped with a very low noise level during operation.
How to change a filter
You can easily change the filter yourself. In this video you can follow the procedure in detail. If required, our service technicians will also be happy to come to you to carry out a filter change.
FAQ
FFUs & Filters
What is an FFU?
One FFU (filter fan unit) consists of a high-performance filter and an integrated fan. It draws in the air from the surroundings and emits filtered air of a defined clean quality. The highly purified filtered air is therefore free of particles such as dust, bacteria, aerosols, germs and 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 meters per hour (m³/h) and describes how many cubic meters of room air can be circulated per hour.
Where are filter fan units used?
The FFUs from Schilling Engineering are integrated into the ceiling of cleanrooms, cleanroom tents and cleanrooms to save space. If the filters need to be serviced or replaced, they can be easily accessed from below. FFUs also ensure that our workstations and enclosures for targeted cleanliness. Every FFU from Schilling Engineering is equipped with a high-performance ULPA 15 filter that precisely filters even the smallest particles from the ambient air with a separation efficiency of 99.9995 %.
Why are Finter fan units needed?
Our clean air filters increase safety in the manufacture of sensitive products or products in your clean room laboratory. Adapted to your requirements, the filter fan units guarantee permanent cleanliness. With a central control system, you can operate the clean air filters and coordinate the conditions you require in your Cleanroom.
How often should the filters in the filter fan units (FFUs) be replaced?
There is no general answer to this question. There is no general rule or regulation as to how often filters need to be changed in a cleanroom operation. Our filters generally run for several years without needing to be changed. However, the service life varies considerably depending on the application and the particle load in the ambient air.
Cleanroom knowledge: How often do filters need to be replaced?
Where can I buy replacement filters for my FFU?
You can purchase suitable replacement filters directly from us.
Does changing the filter affect the power consumption of my FFU?
Yes, if the filter clogs, the air flow rate of the fan must be increased as the filter builds up a higher pressure.
A clogged filter can increase the electricity costs of an FFU by 10-20 %. Regularly checking and changing the filters saves a significant amount of energy.
What long-term cost savings does an energy-saving FFU offer?
Our energy-saving FFU SGE-EC significantly reduces maintenance costs.
A single FFU saves approx. 1400 kWh per year compared to a standard MAC10 FFU. This means a saving of 420 euros per year (assuming electricity costs of 0.30 euros/kWh).
