The Institute of Energy and Environmental Technology (IUTA) in Germany has successfully tested compressed air filters at 7 bar overpressure. This move advanced the field of large-scale compressed air filter testing. Before that, the IUTA was only able to test smaller filters. How did the IUTA do that?
In cooperation with Ehrler Prüftechnik Engineering, Palas® has optimized the compressed air filter test rig of the IUTA. Several Palas® aerosol spectrometers and generators were used for the test rig. Under the motto “ Circulation concept increases energy efficiency”, Palas® with its partner raised the volume flow rate from 50 m3/h to 3000 m3/h. The progress in the field of filtration testing has been witnessed together.
Compressed air filter testing needs a breakthrough
The application-oriented IUTA focuses on environmental sustainability, energy supply, etc. It was awarded the title of “site of progress”. Large-scale compressed air filter testing has wide market demand, as such filters are widely used in many sectors, including automotive, food and pharmaceutical industries. However, before the change made by Palas®, the IUTA could only test smaller filters with volume flow rates of up to 50 m³/h. Conclusions by analogy had to be used to deduce the performance of large filters with volume flow rates up to 60 times greater than that. In addition, energy consumption was also a major challenge, and a breakthrough in the field of compressed air filter testing was needed in many ways.
Circulation concept increases energy efficiency
Under the motto of circulation, Palas® and Ehrler Prüftechnik Engineering suggested that the IUTA could pump the circulation up to 8 bar and use additional inline blower fans to ensure that the pre-compressed air is fed into the circular flow. Dr. Wolfgang Mölter-Siemens, manager of the Air Purification and Filtration division said, “If you compress a volume flow of 3,000 m³/h and expand it again, you’ll need 360 kW, but the circulation principle provided by Palas® reduces the energy needed to 25 – 30 kW.” The test rig made use of Palas® welas® digital 1000 P Aerosol Spectrometer and Palas® PLG 3000 Aerosol Generator for the fractional separation efficiency. Palas® AGF 3000 Aerosol Generator was for the charge concentration. Palas® aerosol generators charged the compressed air filters with droplets of compressor oil, thus simulating the contamination of the compressed air. And then the IUTA used software from Palas® to evaluate the data. This enabled the IUTA to measure directly at a volume flow rate of 3,000 m³/h and an absolute pressure of 8 bar.

Additionally, Palas® offered a special airlock system that allowed gravimetric determinations to be conducted at the same as the particle measurement. The IUTA test rig stored data for a long time. It automatically calculated the fractional separation efficiency and indicated factors such as particle size distribution and mass concentration. Dr. Wolfgang Mölter-Siemens also appreciated its user-friendliness and versatility. The Palas® solution will continue to be optimized to further enable the development of large compressed air filter testing in the future.
Palas® has promoted Palas® DFP 3000 Compressed Air Filter Test Rig based on these core products. Palas® complete and proven filtration solutions deserve your trust.
Palas® DFP 3000 Compressed Air Filter Test Rig
Palas® DFP 3000 Compressed Air Filter Test Rig delivers fully-automated measurements of fraction separation efficiency for compressed air filter under overpressure up to 7 bar, offering better results in the process than ISO 12500. An additional filter holder can be supplied for flat filter media. The fraction separation efficiency is measured with the new aerosol spectrometer Palas® Promo® 3000 P, which is equipped with presuure-resistant Palas® welas® aerosol sensors for raw gas and clean gas measurements.
