This Pocket is made with glass microfiber filter, with different lengths and thicknesses, depending on different efficiencies

They are coated, side air outlet, with a thin synthetic veil, besides increasing the resistance exercises also protective action. Consist of a series of pockets attached to a sturdy metal frame. The range includes four different efficiencies: 95%-85%-65%-45% (ASHRAE 52-76).
They are manufactured in various standard sizes, as the following table, and have a large filter surface area compared to the front, allowing, thus, a low-speed air flow in the filter septum crossing. Thanks to the high efficiency, these filters are marked as final in conditionoing public places, such as schools, hospitals, communities, industries, food, etc. |
