Primary filters are usually installed in the central air-conditioning and centralized ventilation systems, intermediate filters are usually installed in the central air-conditioning ventilation systems, pharmaceuticals, hospitals, electronics, food, and other industrial purification; high-efficiency filters are usually installed in the air-conditioning end air supply of the clean room in the industries of optics and electronics, LCD manufacturing, biomedicine, precision instrumentation, beverages, food, PCB printing, etc. The installation of high-efficiency filters is the key to the installation of purification air-conditioning systems and clean room construction and installation.
Installation of high-efficiency filters is the key to clean air conditioning systems and clean room construction and installation, but the clean room should be fully cleaned again, such as vacuum cleaner vacuum cleaner, may not be used with an ordinary vacuum cleaner must be equipped with ultra-clean filter bag vacuum cleaner.
Expanded Information:
In the pharmaceutical industry, high-efficiency filters (HEPA) are used in the production of end filters for the treatment and filtration of space air. Aseptic production requires the mandatory use of HEPA filters, while solid and semi-solid dosage forms are sometimes used in production.
Low dosage and low operating costs. Due to the structure of the filter bed and the characteristics of the filter media itself, the flocculant dosage is 1/2 to 1/3 of the conventional technology. the increase in the cycle of water production, tons of water running costs are also reduced.
