Description
Purpose: widely used in air filtering field and general air adjusting system. Introduction: AF (pre filter / coarse filter / air filter) is a blue-white filtering material mainly applicable for absorbing large dust particle in the air to prevent blockage in medium- and high-efficient filter so as to prolong their service life and efficiency. Since it adopts super-hard fiber which is coated with stable glue, it has higher hardness and density, better pre-filtration effect and higher air flow rate. Model: AF-200G; Specification: general stock 1m*20m, 1.25m*20m, 2m*20m. Also make according to customer’s order.
