Q1: About air compressor
A1: The equipment needs to use air compressor to generate standard air flow through commissioning for filtration test. The equipment itself does not include an air compressor, which needs to be prepared by the customer.

Q2: The small ticket is not printed clearly
A2: Please open the cover. Check the ink cartridge and printer voltage display. If the ink cartridge is sufficient, the voltage needs to be fine-tuned to see the effect.

Q3: Use the same settings, but reduce the number of particles
A3: After continuous testing for about 24 hours, the number of particles may decrease. It is necessary to remove the container and clean the solution inside. If there is dirt, please also clean it. Then prepare new solution and pour it in.
