My friend, you want to ask whether the pump in the medical negative pressure system will be contaminated, right?
The medical negative pressure system for hospitals is composed of an integrated vacuum pump, control system, buffer device, automatic control valve, etc. Because medical negative pressure systems are used in hospitals to absorb technology, they are used in intensive care units, operating rooms and other places. Generally used for sputum suction, obstetrics, removal of necrotic tissue/fluid, etc. This depends on whether the hospital's vacuum pipeline is equipped with a waste recovery filter device. Generally, regular equipment factories will be equipped with these devices. If not, they may be sucked into the pump body. It is best to have safety infrastructure and protective measures in place when servicing this type of vacuum pump. You can search for Waco Vacuum to learn how to repair it
