Product Description

                   Dust Free Workshop Negative Pressure Weighing Room Negative Pressure Weighing Table

Product Description

       Negative pressure weighing room is a purification equipment designed for weighing raw materials, drying materials, or sampling products in the purification area. It is mainly used in places such as pharmaceuticals, microbiological research, and scientific experiments. The system is equipped with primary, medium, and high-efficiency filters, which provide a vertical unidirectional airflow to the weighing work area, effectively controlling dust flying. Most of the clean air circulates in the work area, and a small amount of clean air is discharged to the background area, creating negative pressure in the work area relative to the background area, preventing cross contamination, and protecting the clean environment and indoor personnel safety.

Product Superiority

The integrated circular arc design of the workspace ensures no dead corners, no dust accumulation, and easy cleaning.
Wind curtain isolation, convenient entry and exit of personnel and materials, easy operation, and no hygiene blind spots.
The patented design of differential pressure balance ensures that the pressure difference in the background area remains unchanged.
Unidirectional flow pattern is good, dust does not diffuse, and the dust capture effect is good.
Cooling units can be added to ensure that the temperature remains within the control range during equipment operation.
Based on the company's testing methods, the filter grade can be reasonably selected.
Integrate weighing equipment control into this device according to customer requirements.
The isolation methods include air curtain isolation, soft curtain isolation, and organic glass isolation.
The return air orifice plate is fixed with strong magnetic force, making it easy to disassemble and assemble.
