I am currently using a glass filtration system with membrane disc filters. I mostly use .45 um disc filter papers and everything is smooth and fine. However, recently I got some .22 um disc filters and my vacuum pump doesnt seem to be able to push the finish product through it. I have an air admiral that provides a max of 20 mmHG i believe. Would getting another vacuum pump that provides closer to 30 mmHG solve this issue?
