Clean air conditioning system ducts and equipment in the installation should be noted:
(1) duct in the flange connection is not allowed to use asbestos ropes and other friable materials to do the gaskets, in the flange it is desirable to use the sealing of the strong 850J flame-retardant sealant tape gasket.
(2) air duct in the installation, before removing the two ends of the sealing paper. If the ground ash on more, before assembly should be laid clean matting. Avoid contamination in the duct. After installation should be placed in the duct 500 ~ 1000W tungsten iodine lamp for light transmission check, the requirements do not allow the tube outside to see the light transmitted.
(3) in the air-conditioning unit or fan connected to the hose connector should not be used easy to accumulate dust canvas, can choose artificial leather or special soft rubber and other materials.
(4) when the clean room around a strong vibration of the equipment. In the air duct to the clean room as far as possible to use vibration isolation bracket, to avoid vibration and noise transfer to the clean room.
(5) because the clean air conditioning system will generally be installed in the end of the system, high-efficiency filters into the clean room (area) before the location, in order to reduce the entire system in the initial transportation of high-efficiency filters on the pollution. Should be in the seven construction works and clean air conditioning system all construction and installation is completed, and a comprehensive wipe and blowing, the first start the equipment in the fan for operation, to be fan running 24h, and then install high-efficiency filters. Before installation, the high-efficiency filter in the protective bag should be checked for damage and deformation, and the header glue and filter paper for cracks and sand holes, and the filter paper should not be touched with hands or tools.
Installed in the wooden frame of the filter, the gap between the wooden frame and the wooden frame must be closed with sealing gaskets, gaskets using closed-cell sponge rubber sheet, neoprene rubber sheet, latex gasket board and other materials, thickness of 6 to 8, gasket joints shall not be butt joints or lap joints, it is best to use the joints shown in the figure.
(6) before and after the medium and high efficiency air filter. Should be set up to measure the pressure hole or differential pressure alarm device to check the efficiency of the filter. All levels of clean room air purification should be used in primary, medium and high efficiency filters for three-stage filtration.
(7) in the new air ducts and return air ducts should be set on the total airtight control valve.
(8) clean room exhaust system should be set up on the control valve, check valve, to prevent outdoor air back into the clean room.
