Melt blown sheet, protective material particle passing rate efficiency testing bench

:

Suitable for testing the efficiency of filter media at levels 0-99.99%, testing the filter media according to standards. The design structure of the test bench is compact and lightweight, and during the operation and testing process, only suitable power and compressed air (without water or oil) need to be provided, making it suitable for use in laboratories, factories, and other occasions.

Fix the filter paper on the fixture and test the air volume corresponding to the required filtration rate. The aerosol generated by the aerosol generator is adjusted, then electrostatically neutralized, and uniformly mixed with the filtered test air before entering the test area and passing through the filter material.

ISO-29463Efficient filters and filter media for removing particles from the air

[Features]:

1. Automatically calculate filtration efficiency testing and airflow resistance.

2. The efficiency test uses two high-precision online counters to measure and detect the aerosol concentration upstream and downstream of the sample, ensuring the authenticity and accuracy of the sample used upstream and downstream.

3. The misting system developed by HCT Group in South Korea features fine atomization without moisture, stable concentration, and stainless steel material that is corrosion-resistant and durable.

4. 10Inch color touch screen control, simple and intuitive operation,Support remote maintenance and automatic calculation, display, printing, and output of test results by the system.

5. Imported exhaust fan with automatic flow regulation.

MainlyComponents:

1.aerosol generator

Mainly used for experiments that require high concentration aerosols, using 0.3um PSL standard particles, the main particle size range emitted is ≥ 0.3um, accounting for more than 70% of the total, and can continuously and stably produce aerosols. Provide test particles upstream of the filter material.

2.particle counter

Mainly used to monitor the upstream and downstream particle concentration of the tested filter material,Obtain the efficiency of the tested filter material.

3.Differential pressure sensor

Mainly used to test the pressure difference (or resistance) of the tested filter material at a certain test flow rate.

4.aluminum alloy fixture

Mainly used for compacting and sealing the tested filter material.

5.Imported fan

Mainly used to provide experimental flow rate for filter materials, with automatic flow control.

6.Static neutralization device

Remove the charge from NaCl particles to make particle counting measurements more accurate.
