Functions

This instrument is used for F-class plate and bag filters testing, including resistance, counting efficiency, flow rate – resistance curve etc. 


Advantages

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.

The electrical control and measurement system of the test rig uses the upper computer software system and the Siemens PLC to form an electrical control cabinet, ensure the stability of the control system.

The test rig adopts an advanced online monitoring software system. It can be operated in two modes. In automatic mode, installed the filter, input the size of filter, set the test flow, and test process (including self-cleaning, particle number judgment etc.) completed automatically. Test results are directly reflected on the computer LCD display at a glance. If air volume under different resistances is need, manual mode should be used. 

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.
