Flat Plate, W-type Filter Element Filtration Efficiency Testing Equipment
Application
It is used for the performance test ofEPA filters, and F6-H14 filter productsof different grades can be tested. Flat plate, W-type, bag type, cylinder filter can be tested.
The test result is the over all counting efficiency @0.3μm, @0.5μm, ePM2.5,resistance, air flow-resistance curve.
Equipped with SC-189, the following indexes can also be tested: dust holding capacity, arrestance, pressure drop vs. dust load, arrestance vs. dust load, etc,.

Features
The filter to be tested can be conveniently installed in the test fixture. Test aerosol and clean air are evenly mixed and passed through the tested filter. Resistance and filter efficiency are obtained by detecting the pressure difference and concentration difference downstream and upstream of the filter. Filters are graded according to their average efficiency.
Adopted the main control board and upper computer software system to ensure the stability of the control system.
The advanced on-line monitoring software system is adopted. Install the filter, input the filter parameters, set the test flow and adjust the aerosol concentration, then the test automatically completes the following process: self purification, particle number judgment, and test. The test results are reflected on the computer LCD display, which is clear at a glance. If resistance data under different air volume are needed, please set the test air volume in the software (set by the percentage of rated air volume).
The start and stop of the aerosol generator, the conversion of the upstream and downstream laser particle counter, and inflation and sealing all are automatically controlled by the corresponding solenoid valves.
The test system uses positive pressure, sets the air volume through software, and uses the frequency converter to realize automatic control of air volume.
Functions such as test report printing, label printing, and database management are available.
The system uses a bypass diluter with large dilution ratio and reliability.

Generally, packed with wooden case. We can do some adjustments in terms of your special requirement.
6. Can the mask tester be certified?
There is certification requirements for mask only, and there has no relevant certification requirements for mask tester, but a calibration report is required. we will provide a calibration report with a randomizer for our mask test instrument. The calibration report is valid for one year. After then, we can also support the corresponding calibration service for small fee.
7. Do you have after-sales service?
We can provide on-site installation and commissioning service for you, but you need to bear the travel expense of our engineer. The warranty period will be one year. Free replacement parts will be supplied during this period. Only accessories and corresponding shipping charges will be charged out of the warranty period.
8. Is there an English interface for your instrument?
Our instrument can be customized on the base of your demand. For example, both mask tester and filter material tester can be displayed in Chinese, English and Korean interfaces. The instruction manual is available in both Chinese and English.
