HEPA Filters

Mark Air-Particulate Control Systems manufactures HEPA filters, Room HEPA Filters and Air Intake Filters that offer high performance, need less maintenance and are stringently tested at factory for leakage, integrity and airflow. The filters are manufactured as per international standards using100% glass micro fibre, fire retardant media. HEPA filters are efficient in blocking particles up to 0.3 micron and larger particles at a minimum efficiency of 99.97%. As HEPA filters remove sub-micron particles and as the filter media are delicate, these can get damaged even while storing.
To ensure that the HEPA filters installed in the equipment/Air Handling Unit (AHU) are not damaged, a few tests have to be carried out. These are Air velocity checking, HEPA filter Pressure drop test and HEPA filter Integrity Test (DOP Test). In clean rooms HEPA filters are installed in the Air Handling Unit or in the specially designed Terminal Plenum. Apart from Clean Rooms HEPA filters are used in Lab Equipment employing Air filtration such as Laminar Flow Workstations, Biological Safety Cabinets, Air Showers, Positive Pressure Modules etc.
