| Positive Pressure Modules We designed these Positive Pressure Modules in such a manner so that these can be capable in providing a clean area within a small enclosure or cell. The working principle of these pressure modules is almost same to the Laminar Airflow. At the rear end of the unit, the pre-filter is fixed. For sucking the air, a bowler assembly is used. After sucking our the air, the air is passed through the HEPA filter chamber. The highest level of air filtrations is taken place inside the HEPA filter. |
