All gas lines have dry contaminants (such as pipe scale, dirt, and rust) that will damage or even destroy your downstream equipment. Using a Namdaran Petrogas Industries “NPI“ Dry Filter will remove all forms of dry contamination, lengthening the life of your equipment and saving thousands of Rials in maintenance costs. NPI range of Dry Gas Filter is multiple elements filter designed for filtering dust and other solids from gas flows with a minimum pressure drop. NPI Dry Gas Filters offer efficient and effective removal of dust and other solids from gas flows at relatively low pressure drop. The larger, heavier particles settle to the bottom of the inlet chamber upon entering. The gas then passes through the filter elements which trap and retain the finer particles. A ‘Quick Opening End Closure’ is provided for access to and cleaning or replacement of the filter elements. The life cycle of the filter is dependent upon dust and dirt loading and the corresponding increase in pressure drop.
