Study on the model SGL-83 filtration efficiency measuring device
The advantages of the device are simple in structure
easy for operation and stablein performance. It provides multifunction such as generating both the small size aerosol and large size dust
conducting the filtration efficiency and performance tests for dusts for protection equipment or filter media.
Some new techniques have been employed to produce test dust: Ultrasonic fog generator for producing aerosol and silicon controlled electromagnetic oscillation methods for generating dust. Therefore the concentration and quantity of the test dust are stable and controllable.
The device has the maximum detectable efficiency of 99.99% for aerosol and 99.5%for dust.
The tests on various dust protection equipment and filter midia showed the good stability and reproducibility of the device.
