Constituent part :
Aerosol generator
- It is mainly used for the test of high concentration aerosol,PSL standard particles of 0.3um are used, and the particle size range of the main particles emitted is ≥0.3um, accounting for more than 70% of the total, which can continuously and stably produce aerosols. Upstream of the filter material, the test particles are provided.
Particle counter
- It is mainly used to monitor the concentration of upstream and downstream particles of the measured filter material and obtain the efficiency of the measured filter material.
Differential pressure transducer
- It is mainly used to test the pressure difference (or resistance) of the measured filter material under a certain test flow rate.
Stainless Steel Clamps
- Mainly used for the pressure and sealing of the measured filter material.
Air pump
-Mainly used for the test flow through the filter material, stable flow, green energy saving, small vibration noise.
Electrical control and software
Circuit control and operation of equipment, calculation and data processing of software, stability judgment of upstream concentration, operation control, parameter setting.
