AstroFan EC FFU Installation

Whisper-quiet, energy-efficient AstroFanTM EC fan filter unit (FFU) and watch as it is installed into a ceiling grid system. Changing out the filter is a snap, as it can be done from the room side by removing the facescreen. These FFUs also allow room outside aerosol injection and testing for convenience. With the AstroFan EC FFU, you have multiple control options based on MODBUS protocol, including the connection of Ethernet cables for a communication link to a control panel.

AAF Flanders FFU + Air Filter = A Single Manufacturer

AAF Flanders offers the most comprehensive manufacturing capabilities in the industry. We are the only manufacturer of FFUs that also manufactures the air filters used in the units. Our product development and technical leadership in both filtration and equipment manufacturing gives us a unique advantage to understanding and delivering on the challenges and opportunities for cleanroom environments.

We perform all aspects of the production process from the research, design, and development of the equipment and filters, to the fabrication, assembly, and testing, entirely in-house. Our cleanroom production environments, located worldwide, are in accordance with the most advanced testing standards resulting in unparalleled product performance. At AAF Flanders, our seamless integration ensures exceptionally high product quality and operational excellence to minimize your risk.
High Purity Solutions

State-of-the-Art Testing

AAF Flanders has established a testing methodology that is among the most comprehensive and accurate in the industry. Testing is essential in documenting filter efficiency within the FFU, diagnosing problems, and assisting in research and development. Our testing facilities meet the highest standards for quality control. We perform routine, specialized testing for HEPA and ULPA filters, to ensure the cleanroom filtration products you receive meet your performance requirements.

Quality and Process Control

Meticulous scrutiny during every phase of the production process enables AAF Flanders to trace a filter or FFU back through the manufacturing process. Each unit and filter are identified by serial and order numbers and labeled with performance criteria, size information, operator number, and part number. This elaborate quality process control ensures that you receive only the highest quality cleanroom products that meet your most stringent requirements.

Enhance Energy Savings

The energy-saving AstroFan EC FFU has the highest efficiency airflow rates when coupled with AAF Flanders’ eFRM filtration media technology, delivering significant benefits in energy consumption and performance. eFRM media is proven to be more reliable due to its high level of mechanical strength for resistance to damage, leaking, or failure. It is the industry’s first and highest - performing membrane media to be compatible with polyalphaolefin (PAO). eFRM membrane media has the lowest available pressure drop to reduce operating costs while improving production yield.
