Negative pressure weight mask

The weighing room(cover) is a local purification device used for pharmaceutical, microbial research and scientific experiments. It provides a vertical one-way air flow. Part of the Clean Air circulates in the work area, and part of it is discharged to the nearby area, causing negative pressure in the work area. Dust, reagent weighing, and separation in the equipment can control dust, reagent spillage, and upwelling, prevent the inhalation of dust and reagents to the human body, and avoid cross-contamination of dust and reagents, and protect the environment and indoor personnel. safety.
The measuring mask(room) operation area developed by our company is protected by a hundred levels(ISO 4.8) vertical laminar flow, referring to the 2010 version of GMP's Class A requirements, in line with the revised version of China's GMP2010(Article 52, 53).
The equipment structure equipment consists of working area, return wind box body, fan box body, out wind box body and outer box body. The control panel is located on the front of the internal working area of the equipment. The control panel adopts a light-touch LED control panel, which can control the fan starting and stopping, adjust the fan working conditions, and adjust the wind speed required in the working area. There is a pressure differential meter next to it, and the resistance of the test filter has a exhaust adjustment board inside the air supply box body, which can adjust the exhaust volume of the equipment within a reasonable range.
operating principle
The equipment adopts the form of vertical one-way flow, and the return wind is pre-filtered through the primary filter to dispose of the large particles of dust particles in the air flow. After pretreatment, the air is filtered twice through the medium effect filter to fully protect the high-efficiency filter. Under the pressure provided by the centrifugal fan, the high efficiency filter is used to make it meet the requirements of cleanliness. The operation area and the external environment form a relatively negative pressure, so as to ensure that the dust in this area will not spread outdoors, playing a role in protecting the external environment.
Our company can tailor the products for you according to your needs.
Description of a 100-magnitude negative pressure weighing chamber
The overall structure and material accessories of the negative pressure weighing room are strictly designed in accordance with the new GMP requirements. They are widely used in local purification equipment dedicated to pharmaceuticals, microbial research, and scientific experiments. The negative pressure weighing room provides a vertical one-way air flow. 90 % of clean air circulates in the work area, and 10 % of clean air is discharged outside the equipment, so that the work area forms a negative pressure environment to prevent cross-pollution, which is conducive to ensuring a high cleanliness environment in the work area.
The dust and reagent weighing in the clean area of the weighing room can effectively control the cross-contamination of dust and reagents and prevent the contamination of materials and personnel outside the working area of the equipment.
Working principles:
The negative pressure weighing room adopts a one-way vertical and DC structure design. The return wind is first filtered through the initial effect filter, and the larger dust particles in the air are filtered and processed. The treated air is then filtered through the medium effect filter for a second time. Play a role in protecting highly efficient filters. Therefore, the useful life of high efficiency filter is improved.
After passing through the high efficiency filter under the pressure provided by the centrifugal fan, the Clean Air reaches the cleanliness required by the GMP after passing through the primary, middle, and high efficiency filters. About 90 % of the Clean Air passes through the uniform drift-net, forming a uniform vertical air flow to the clean work area of the equipment, while about 10 % of the Clean Air is discharged outside the clean work area to form a local negative pressure environment. In the negative pressure vertical DC environment, dust and reagent weighing can prevent dust from spilling, rising, and diffusing outside the clean area, which plays a role in protecting operators and the external environment.
