TSI 8130 – The Automated Filter Test Model
Aeropro has added one of the most powerful and accurate filter-media testing devices to our R&D facility in Shanghai, which is the TSI 8130 Automated Filter Testers (AFTs). This testing device can be used to test a wide assortment of Filter media, particulate respirator filters and disposable filtering face pieces.
TSI’s Automated Filter Testers Models 8130 have proven track records of durability, reliability, and minimal maintenance, meeting the demanding requirements of manufacturing and quality control environments. The device can be used as stand-alone tester to check a few filters per day or to integrate the tester in an automated, high-volume production line. Specially designed aerosol generators and laser photometers enable highly repeatable and reproducible filter-efficiency measurements. In addition, the Model 8130 feature a high degree of automation and self-diagnostics that greatly simplifies operation, increases throughput, and improves overall measurement performance. TSI filter tester are ideally suited for QC testing.
Basic Working
The operation of Model 8130 is simple, fast and highly automated. The filter is placed on the lower half of the filter holder. After the test is initiated, a pneumatic cylinder quickly lowers the top half of the filter holder and aerosol is passed through the filter. The aerosol can be NACL, DOP or Paraffin oil. Two light-scattering laser photometers simultaneously measure the upstream and downstream aerosol concentration levels. The particle penetration value is determined from the ratio of these two readings. By using two laser photometers, instead of one, measurement accuracy and throughput is increased. Highly accurate, electronic pressure transducers determine filter resistance and flow rate. Pressure and photometer readings are taken between every test to determine the zero offsets and background values.
Benefits
a) Compliance with regulations
The TSI Automated Filter tester Complies with 42 CFR part 84 certification testing, EN 143 and related standards testing and Quality control testing.
b) Simple, fast and automated operation
The device is highly user friendly with dual photometers for increased accuracy and speeds. It has self-check diagnostics with external control interface for automation if required. It can perform unattended operation for prolonged loading tests and can store and recall multiple recall operations.
c) Highly consistent test results
The test machine produces stable aerosol of known size distribution and measures efficiencies up to 99.999% (measures penetrations down to 0.001%).
d) Designed for manufacturing environments
The device operates with minimal maintenance and can test more than 5 filters per minute. The machine can be integrated with automated production lines.
