Automatic Filter Efficiency Tester can simulate the actual use environment of masks or filter materials, and test the filtration efficiency and filtration resistance based on the oil mist and salt spray methods required by the standard.
Test parameters meet the test method requirements in NIOSH42CFRPart84 and GB/T2626 standards.
In addition, the mask pfe tester can also test the permeability of filter materials, and the test apertures are 1/1, 1/2, 1/4 and 1/8;
Test material: layered mask or filter material;
Test methods: oil mist test and salt spray test;
Test parameters: filtration efficiency, filtration resistance, etc.
Automatic Filter Efficiency Tester can accurately evaluate the filtering performance of masks or filter materials, and provide data basis for research and development of new filter materials, product quality control, material performance verification, etc. It is a good choice for product performance verification in scientific research, testing, industrial production and other fields.
Testing nominative:
Technical requirements for NIOSH42CFRPart84 respiratory protection device;
GB/T2626 respiratory protective articles-self-priming filter respirator for preventing particles
Operational environment
1. Climate and environment
Have the right to change and improve their products, but have no obligation to improve and install the produced products.
This mask pfe tester operates under the following conditions:
Elevation < ＜2000m
Operating temperature: 13 ~ 30℃ (56 ~ 86 ℉), relative humidity: 25 ~ 75%
Storage temperature: 10 ~ 43℃ (50 ~ 110 ℉), relative humidity: 20 ~ 80%
The instrument can be placed in the operating environment required by the standard, so that the humidity control of the sample can be consistent with the operation of the actual wear test.
2. Operating environment
The mask pfe tester is used in residential, commercial and light industrial environments, and complies with BSEN50081-1 and BSEN50082-1
In a clean environment without vibration, corrosive medium and strong electromagnetic field interference;
The variation of power supply voltage is within 10% of rated voltage;
Ventilation conditions: no wind/air flow at the position where the sample is located cannot be greater than 0.2m/s;
Install correctly on a firm foundation (levelness is 0.2/1000).
Preparation and installation
1. The system equipment should be placed in a relatively clean environment, away from the flowing air source and dust source;
2. Clean the equipment before use;
3. Before use, please check whether all kinds of hoses and electrical connections of the test bench are well connected to avoid looseness caused by transportation bumps;
4. Prepare the filter material to be detected;
5. Connect the input cable on the side of the test bench to the external power supply (AC220V) correctly;
