• Fan system: High-quality fans are used to ensure stable operation for a long time, reduce noise and vibration, and provide long-lasting and durable performance.

Double-layer negative pressure structure: The uniquely designed double-layer structure effectively prevents gas leakage and ensures negative pressure in the operating environment.

• Uniform air distribution performance: Through the well-designed air supply system, it realizes uniform air distribution in the whole working area.

Automatic adjustment of air speed: Combined with the automatic or manual adjustment function, the air speed can be adjusted according to the need to maintain the cleanliness of the working area.

• Perfect sealing design: The liquid tank design ensures the sealing performance of the equipment and prevents any possible leakage.

Consistency of internal and external structure: Consistent design of internal and external structure ensures the neatness and aesthetics of the equipment, as well as easy cleaning and maintenance.

• Filter differential pressure display device: real-time monitoring of the filter status to ensure filtration efficiency.

• Unique air duct design: effectively control the working noise of the whole machine and provide a quiet working environment.

Even flow membrane design: when weighing and dispensing dust and reagents in the working area, it can effectively control the spillage and cross contamination of dust and reagents.

• Hundred-level cleanliness protection: the weighing operation area is protected by hundred-level vertical laminar flow to meet the high standard of cleanliness requirements.

• Chamber Material

Neg Furls negative pressure weighing chambers are constructed from high quality SUS304 stainless steel for corrosion resistance and strength, ensuring a robust and long lasting unit. Stainless steel is not only easy to clean and maintain, but can also be adapted to a wide range of working environments and meets the requirements of GMP (Good Manufacturing Practice).

• Polymer homogenizing membrane

The air outlet surface is equipped with a polymer equalization membrane, which helps to ensure an even distribution of wind speed, which can be controlled within 5%-10%, thus providing a stable airflow environment for weighing operations.

• Filtration System

Neg Furls Negative Pressure Weighing Cells are equipped with high efficiency filtration systems, including primary, intermediate and high efficiency filters, which are capable of capturing dust and contaminants of different sizes to ensure clean air and meet stringent cleanliness requirements.

• Control Systems

The control system provides a variety of options, including normal control, LCD display and operation, and PLC control, etc. Users can choose the appropriate control method according to their needs. The air speed display and set alarm function also provide convenience for the operator.

• Lighting and Sterilization

The weighing room is equipped with sufficient lighting to ensure that the illuminance at a height of one meter is more than 300 Lux, and optional germicidal lamps or ozone generators are available to maintain a hygienic and safe weighing environment.

Negative pressure weighing room adopts vertical unidirectional flow airflow form, air flows vertically downward in the working area, after pre-filtering by the primary filter, most of the air returns to the working area through the high-efficiency filter to maintain the cleanliness of the working area, while a small portion of the air is discharged outside through the exhaust system to maintain the negative pressure state.
