air shower
Air shower room is an essential cleaning equipment in modern industrial clean workshop, which can remove the dust on the surface of people and things, and at the same time play the role of buffering and isolating clean areas and unclean areas on both sides of air shower room. The equipment is widely used in food, medicine, bioengineering and precision electronics. Shower room is divided into ordinary type and interlocking type. The ordinary type adopts the control mode of manually starting the shower, and individual operators will choose the escape mode of "leaving without taking a shower". This makes it difficult to ensure the cleanliness of the air in the clean area. It may even affect the quality of products. In the clean room, under dynamic conditions, the source of bacteria and dust is the operator. Before the operator enters the clean room, he must use clean air to blow away the dust particles attached to the clothes.
Efficient air supply outlet
Widely used in electronic industry, precision machinery, metallurgy, chemical industry and medical, pharmaceutical, food and other departments to purify air conditioning systems. This device is mainly composed of static pressure box, high efficiency filter, aluminum alloy diffuser and standard flange interface. Beautiful appearance, simple structure and reliable use. The air supply outlet is installed at the bottom, which has the advantage of convenient installation and replacement of clean room filters. The filter adopts mechanical compaction or liquid tank sealing device to ensure that the air outlet is installed without leakage, with reliable sealing and good purification effect.
Transfer window
The transfer window is mainly suitable for the transfer of small goods between clean areas and non-clean areas, or between clean rooms, which can effectively reduce the opening times of clean room doors and reduce the pollution of clean areas. According to the use requirements, the surface of the transmission window box can be sprayed with plastic, and the inner container can be made of stainless steel, which is beautiful in appearance. The two doors of the transmission window adopt electronic interlocking or mechanical interlocking devices, which can effectively prevent dust from being brought into the high cleanliness area from the low cleanliness area.
Purification platform
The clean workbench in the dust-free workshop can maintain high cleanliness and local purification on the workbench according to the requirements of products or other uses. The clean workbench can form aseptic and dust-free local purification in the local space of the console, and its main components include pre-filter, high-efficiency filter, fan unit, shell, static pressure box, table top and supporting electrical components. Structural requirements of clean workbench in dust-free workshop: the countertop is made of wood-plastic veneer and laminated board, or stainless steel; The box body is easily deformed by hot-rolled steel plate and gas welding of skeleton, and it is folded by cold-rolled plate and welded by high current. The inner surface needs to be pasted with sound insulation material, and the size should be suitable for passing through ordinary doors; The box is sealed, and all gaps are sealed with sealant; The cross section of the operation area should be the same as the air supply cross section of the air filter as far as possible to minimize blind spots; The fan and motor should be small fans with high pressure and low noise, and the connection between the fan and the box should be soft. Vibration reduction measures should be taken for both motors and fans. Lampshade and fluorescent lamp should be set in the lampshade as far as possible, and clean airflow should pass through the lampshade; Pre-filter, pre-filter must be set, with large capacity and initial resistance less than the air volume used under 50Pa; For high-efficiency filters, use large-area filters as much as possible to reduce the number of air filters. The double-ring sealing system combining sealing and guiding should be adopted for the sealing between the filters and the frame.
FFU fan filtering device
FFU is the abbreviation of English, and it is called fan filter unit. Chinese means "fan filter units", also known as air filtration unit. The fan sucks air from the top of FFU and filters it through primary and high-efficiency filters to provide high-quality clean air for clean rooms and microenvironments with different sizes and cleanliness levels. The FFU implementation standards of different purification engineering enterprises are slightly different. The common index in the industry is that the filtered clean air is sent out at a uniform speed of 0.45 m/s 20% throughout the air outlet, but the stability is quite different. The purification engineering industry began to pay attention to the two-way acceptance criteria of product quality and stability, and gradually reflected the project cost performance more truly with the field test data (previously relying on industry reports).
Laminar flow hood
Laminar hood is a kind of air purification equipment which can provide local high cleanliness environment. It mainly includes box, fan, primary air filter and high efficiency air filter. Damping layer, lamp, etc. The box is made of plastic spraying or stainless steel. The product can be hung and supported on the ground, with compact structure and convenient use. Can be used alone, but also can be connected to form a strip-shaped clean area.
