Description:
Medium-efficiency and Sub-High-efficiency box filters use the complex chemical fiber synthetic fiber and glass fiber filtering materials and are equipped with inside metal supports and high-strength outside frame of galvanizing plate. They have the characteristics of firm structure, low resistance, high air quantity, and long service life, etc. Furthermore, their filter elements can be replaced and their use-costs can be reduced.
Application:
Generally, they are used in the medium-efficiency and sub-high-efficiency filtration of the central ventilation systems and extensively used in the cleansing workshops of intelligent mansions as the prefilteration of the high-efficiency filters. They are suitable for the ventilating and air conditioning systems with changed air quantity.
Structure:
They are separated and supported with inside metal supports and have high-strength outside frame of galvanizing plate.
