The company supplies these panel filters in wide variety of filter media for each and every application depending on lower size threshold of particles to be filtered and filtration efficiency. Different filter medium is selected for different filtration application. Filter media are characterised by two important parameters: [1] filtration efficiency for given particle size threshold and [2] resistance to flow of air gas or pressure drop. The company supplies panel filters in ranges of high efficiency particulate air filters, high efficiency and heavy-duty filters, pocket filters, fine filters and pre filters.
