Shielded filter and dust shields perform three functions: they attenuate EMI, they provide for a passage of cooling air, and they filter dust from the air flow. Designed for use in industrial environments at low to medium air flow rates, they can be cleaned either by inversion and agitation in a suitable solvent or by air blasting. The filter is comprised of three layers of corrugated aluminum mesh aligned to provide maximum dust trapping effectiveness and minimum resistance to airflow. The filter material is contained in a rigid "C" channel aluminum frame of all welded construction and protected on each side with an expanded metal grid.
Electronic filters and dust shields are manufactured to meet the needs of individual applications. For custom requirements, please supply a detailed drawing with the following information:
Outer dimensions of filter.
Type of gasket required.
Location and size or type of fixing holes or fasteners (6/32 or 8/32 UNC, preferred). Use table below as a guide for hole/insert spacings.
