The test state of the filter is: dynamic test and static test. Filter test methods are: sodium flame and oil mist method. Filter efficiency of the test methods are: atmospheric dust test and artificial dust test method.

Clean room is defined as: the dust and microbial contamination regulations require environmental control of the room and area. Local space purification refers to: only the indoor work area-specific local space of the space with suspended particulate concentration to achieve the required level of air cleanliness. Cleanliness is defined as the number of permissible particles […]

The framework of the filter is: to accommodate the filter, to maintain the shape of the filter, subject to external forces when the object. Is the support body? Supporting the filter material or the air passage between the filter media to maintain a certain shape of the part.

The standard fold number of the high efficiency filter is determined by the height of the separator paper and the tightness of the separator paper and filter paper assembly. For example: the standard frame of the filter (610 * 610 * 120) mm is: first remove the thickness of the two sides of the board, […]

The filter unit specified by the manufacturer in the unit of time to deal with the design of air flow, the unit to m3 / h said, and the amount of dust is subject to the end of the filter when the resistance imposed by the total mass of artificial dust and the average of […]

The filter that performs the performance test according to the standard is called the test filter. The end filter refers to a filter used to trap the artificial dust of the test filter.

Atmospheric dust refers to the suspended particles contained in the natural air of the room which is connected with the outdoor or outdoor, and the artificial dust is mainly composed of road dust, carbon black and short fiber, the proportion is 72%, 25%, 3 % And so on.

The current sealant is A, B plastic, and other manufacturers with a polyurethane adhesive. A, B glue to adjust the ratio of rubber 1: 2, the sealing performance is better, but once the imbalance, it will cause serious consequences, such as: glue not dry, or plastic bubbles and other phenomena, resulting in the filter scrapped.

KLC high efficiency air outlet shell made of high quality cold rolled steel plate, the surface electrostatic spray, with static pressure box high efficiency filter, diffuser, in the alteration and the new level of clean room, can be used as a terminal high efficiency filter in the clean shed , With less investment, construction and […]

FFU laminar flow air supply unit can be connected to the module, making the FFU widely used in clean rooms, clean bench, clean production lines, assembly-type clean room and laminar flow hood applications. FFU with the beginning of the two-stage filter efficiency filter. Fan from the top of the FFU inhaled air and through the […]
