Weighing hood

Product Introduction

The weighing hood is a kind of special special studio for sampling, weighing, analysis and other industries. It can control the dust and dust in the work area from spreading to the outside of the operation area, and ensure that the operator does not inhale the operated items. A special purification equipment for controlling dust flying. The indoor air is forced into the static pressure box by the centrifugal fan through the primary and medium-efficiency filters, and is blown out from the outlet surface of the air diffuser unit after passing through the high-efficiency filter. The clean air flows through the work area at a uniform cross-sectional wind speed. Thereby forming a highly clean working environment. The operating area of the weighing hood is maintained at a negative pressure, and 10% of the circulating air is discharged. The air in the weighing hood is self-circulating through a three-stage filter system (a high-efficiency filter removes 99.99% of particles ≥ 0.3 μm and all dust), and the design meets the GMP requirements of the pharmaceutical factory. Weighing and distributing dust and reagents in the equipment can control the spillage and rise of dust and reagents, prevent the inhalation hazards of dust and reagents to the human body, avoid cross-contamination of dust and reagents, and protect the external environment and the safety of indoor personnel.
