Housing with high-quality cold-rolled steel production HEPA HEPA, the surface electrostatic spray containing plenum, high efficiency filter, diffuser plate, alterations and new clean room at all levels, can be used as a terminal device in a clean and efficient filtration ceiling, etc., with less investment, simple construction and so on. Application of a cleanroom aluminum keel structure 2, due to the height of the clean room by civil height restrictions, but must compact design approach cleanroom. 3, part of the characteristics of a partial purification equipment, hydrostatic tank with low carbon steel materials, high efficiency filter and plenum made a whole. Configure the static pressure at the inlet box - control valve regulating the air uniformity and static pressure effects. 2, light weight, and more convenient, especially suitable for installation in the form of aluminum keel clean room.
