General Ventilation Air Filter Test System SC-16890

It is used for the performance test of air filters for general ventilation, including resistance to airflow test, fractional efficiency test and dust capacity test. Test indicators: initial pressure differential, pressure differential to air flow rate, initial fractional efficiency, conditioned fractional efficiency, average fractional efficiency, pressure differential as a function of the test dust captured, arrestance as a function of the test dust captured.

Advantages

Adopt imported well-known brand particle counters, differential pressure meter and other components to ensure the test accuracy.

Equipped with independent IPA discharge cabinet, and can judge whether the static elimination effect is complete.

Designed and manufactured according to ISO 16890, the filter tested can be conveniently installed in the test fixture, test aerosol or dust and clean air are evenly mixed and passed through the tested filter. Pressure differential and efficiency are obtained by detecting the pressure difference and concentration difference downstream and upstream of the filter. Filters are graded according to their average fractional efficiency.

Self developed dust feeder, fully automatic dust feeding, dust feeding speed is adjustable.

Adopt the upper computer software system and the control main-board to form the electrical control cabinet, which ensures the stability of the control system.

Adopt advanced online monitoring software system, after install filter - input filter parameters - set test flow - adjust aerosol concentration, the test system complete self-cleaning and particle number judgment automatically, then start the test, and the test results are reflected on computer LCD.

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 works under negative pressure, air volume is set by software, and the frequency converter is used to realize the automatic control of the air volume.

Functions such as test report printing, label printing, and database management are available.
