• Stainless steel

The wall panels of the Neg Furls Negative Pressure Weighing Chamber are made of 304 stainless steel, with a thickness of 1.2mm, a short oil-drawn wire surface, internal rounded corners for connection, and a dead-end-free design, which ensures the sealing of the working area as well as the overall cleanliness and aesthetics.

• Long life fan

The equipment is equipped with a fan designed for long life, low operating noise, low maintenance costs, low vibration, to ensure long-term stable operation and low maintenance needs.

• Double-layer negative pressure structure

Neg Furls negative pressure weighing chambers are constructed with a double layer of negative pressure, which effectively avoids the risk of possible leakage and ensures a tight weighing environment.

• Adjustment of air velocity

The air velocity can be adjusted automatically or stepwise to meet the specific requirements of cleanliness and airflow under different working conditions, ensuring the stability of the weighing environment.

• Material selection

The material usually used in negative pressure weighing chambers is stainless steel, especially 304 stainless steel is the most common, this is because stainless steel has good corrosion resistance, high temperature resistance and easy to clean characteristics, very suitable for frequent contact with chemicals and high cleanliness requirements of the place. In addition, the smooth surface of stainless steel does not generate static electricity and does not affect weighing results, which makes its use in weighing rooms particularly widespread.

• Application Scenarios

Negative pressure weighing rooms play a crucial role in the pharmaceutical industry. In the production of pharmaceuticals, accurate weighing is essential to ensure quality and safety. Negative pressure weighing chambers provide a stable negative pressure environment to prevent cross-contamination of raw materials during the weighing process and ensure compliance.

Negative pressure weighing chambers also play an important role in microbiological research and scientific experiments. In these fields, experiments often involve volatile or hazardous chemicals, and negative pressure weighing chambers are able to effectively control the spillage of these substances, protecting the operator from harm and avoiding contamination of the external environment.

• Structural Features

Negative pressure weighing chambers are designed to be robust and durable, as well as easy and safe to operate. For example, weighing chambers are usually equipped with high efficiency filtration systems, including primary, medium and high efficiency filters, which are able to intercept particles of different sizes and ensure the cleanliness of the air.

• In addition, negative pressure weighing chambers are equipped with appropriate lighting and ventilation systems to ensure that operators can work in good conditions. The intensity of the lighting is usually controlled between 300-500Lx, so that it is not too strong to affect the operator's vision, but also to meet the needs of weighing.

Neg Furls Negative Pressure Weighing Chambers utilize a vertical unidirectional airflow where the return air is first pre-filtered through a primary filter to remove large dust particles, and then secondary filtered through an intermediate filter to protect the high efficiency filter. Under the pressure of the centrifugal fan, it passes through the high-efficiency filter to ensure clean air. About 90% of the air passes through the equalizing membrane to form a uniform vertical airflow, while 10% of the air is discharged out of the equipment through the airflow regulating plate. All airflow is treated with high efficiency filters to prevent secondary contamination.
