Negative pressure weighing hood works
The weighing chamber is a special local purification equipment for pharmaceutical, microbiological research and scientific experiments. It provides a vertical one-way air flow. Part of the clean air is circulated in the work area and partially discharged to the nearby area, making the work area produce Negative pressure prevents cross-contamination and is used to ensure a high cleanliness environment in the work area.
Dust and reagents are weighed and dispensed in equipment to control the spillage of dust and reagents and to prevent the inhalation of dust and reagents. It also avoids cross-contamination of dust and reagents, and protects the external environment and the safety of indoor personnel.
The weighing operation area is protected by thousands of vertical laminar flow ISO 6 (NF, EN, ISO 14644-1).
one. product features:
1 Through the lower settlement type low negative pressure air flow in the operating area, a clean and sterile local environment is created, avoiding cross-contamination between different drugs
2 Effective control of dust, reagent spillage, and uplift to prevent the inhalation of dust and reagents on the human body. It also avoids cross-contamination of dust and reagents, and protects the external environment and the safety of indoor personnel.
3 Primary, middle and high efficiency filter three-stage filtration, liquid tank high efficiency filter meets the test requirements of DOP or PAO
4 Polymer Membrane Membrane Improves Uniformity of Outlet

two. Structure
This equipment is assembled from the work area, return air box body, wind box body, air box body and outer box body. The control panel is located in the front of the device's internal working area. The control panel adopts a touch-type LED control panel, which can control the start and stop of the fan, adjust the fan working condition, and adjust the wind speed required in the work area. When the equipment is installed and used, special personnel must adjust the working condition. ). There is a differential pressure gauge next to it. The resistance of the test filter is also in the interior of the air supply box. There is also an air conditioning adjustment board, which can adjust the exhaust volume of the equipment within a reasonable range (after the equipment is installed in place, it is set by professionals Try not to arbitrarily adjust)
III. How it works
The device adopts the form of vertical unidirectional airflow, and the return air must first be pre-filtered through the primary filter to remove large particles of dust in the airflow. After the pre-treated air, secondary filtration is performed through a medium-efficiency filter to fully protect the high-efficiency filter. Under the pressure provided by the centrifugal fan, through a high-efficiency filter, make it meet the cleanliness requirements. The clean air was sent to the air box. 90% of the air was fed through the air-flow screen to form a uniform vertical air flow, and 10% was discharged through the air flow control panel. All air flows are treated with a high-efficiency filter, so the air supply and exhaust are free from residual dust and secondary pollution is avoided. Due to the formation of a stable unidirectional flow in the work area, the dust emitted in this area will be trapped by the primary and secondary filters under the influence of the unidirectional air flow. The device has 10% of exhaust air, so as to form a negative pressure with respect to the external environment, to a certain extent, to ensure that the dust in this region will not spread to the outside, to protect the external environment.
