The negative pressure weighing room is a special local purification equipment used in places such as pharmaceutical, microbial research and scientific experiments. It provides a vertical unidirectional air flow. Part of the clean air circulates in the working area and part of it is discharged to the nearby area, so as to generate negative pressure in the working area, prevent cross contamination, and ensure a high cleanliness environment in the working area. The questions and answers of the negative pressure weighing room are shared with you:

Question 1: in the 2010 GMP transformation, does the weighing room have to have a laminar flow device?

▍ answer: Yes, the raw and auxiliary materials must be weighed in a specially designed weighing room or weighing room according to the 2010 GMP regulation. There is a vertical downward laminar flow in the weighing room, and the interior is negative pressure relative to the outside, so as to prevent dust diffusion and cross pollution.

Question 2: what is a clean room weighing room?

▍ answer: the clean weighing room is also called the negative pressure weighing room, which is used by the pharmaceutical industry to weigh drugs. It can form a negative pressure vertical laminar flow, in which weighing drugs can avoid harming operators or the external area of the weighing room.

Question 3: what are the components of the negative pressure weighing room?

▍ answer: the main components of the weighing room are: primary efficiency filter, medium efficiency filter, high efficiency filter, flow sharing membrane, fan, 304 stainless steel structural system, electrical system, automatic control system, pressure detection system, etc.

Question 4: what is a negative pressure weighing cover?

▍ answer: the negative pressure weighing cover is also called the negative pressure weighing room, which is a local air purification equipment specially used for weighing raw and auxiliary materials in pharmaceutical factories. It provides a vertical single air flow, in which part of the air flow circulates in the working area, and the other part of the air flow is filtered by the high-efficiency filter and discharged from the equipment, so as to form a negative pressure inside the equipment relative to the outside, so as to prevent dust diffusion and cross pollution, and protect the safety of workers and the surrounding environment.
