Neg Furls Negative Pressure Weighing Chambers ensure the best possible working environment and performance for the user with their superior design and advanced technology.

• The negative pressure weighing chamber utilizes a liquid tank design to ensure a perfect seal. This design not only prevents external contaminants from entering the working area, but also maintains a high degree of cleanliness in the internal environment, ensuring the accuracy and safety of the weighing process.

• The internal and external structure of the negative pressure weighing chamber is designed to be consistent and neat without dead space. This means that it is easy to clean and maintain, and users can easily clean the equipment thoroughly to avoid any accumulation of residue, thus maintaining long-term efficient operation of the equipment.

• Our negative pressure weighing chambers are equipped with a manual inverter system that allows the user to adjust the air speed in the main working area as required. This feature ensures that the wind speed in the working area is always uniform and will not affect the weighing results due to uneven wind speed, providing users with a more stable working environment.

• The filter differential pressure display device can monitor the operation status of each filter in real time. Users can know the working condition of the filter at any time and replace or maintain it in time to ensure that the negative pressure weighing chamber is always in the best operating condition.

• The negative pressure weighing chamber adopts a unique air duct design, which effectively controls the working noise of the whole machine. Even during long periods of operation, the user can work in a quiet environment, improving overall working comfort.

Neg Furls negative pressure weighing chambers provide an efficient, safe and stable working environment through a series of innovative design and technology applications, making them the ideal choice for accurate weighing operations.

Neg Furls is committed to providing the highest quality negative pressure weighing chamber products. Through rigorous material selection and advanced technology, we ensure that each unit delivers the performance and reliability you need for accurate weighing operations.

• Differential Pressure Gauge:

Neg Furls negative pressure weighing chambers are equipped with two highly accurate differential pressure gauges. These differential pressure gauges are used to monitor the pressure difference between the chamber and the outside of the chamber in real time, ensuring that a stable negative pressure environment is maintained during any operation. The differential pressure gauges allow the user to identify and adjust any factors that may affect the stability of the negative pressure, thus ensuring safe and accurate weighing operations.

• Polymer flow-evening membrane:

In order to improve the uniformity of airflow, Neg Furls negative pressure weighing chamber adopts advanced polymer equalization membrane technology. This polymer material not only distributes the air flow evenly, reducing turbulence and dead spots, but is also resistant to corrosion, high temperatures and easy to clean. The application of polymer equalization membrane significantly improves the air circulation efficiency in the weighing room, ensuring a clean and safe operating environment.

• Variable frequency control:

The air velocity control system in Neg Furls negative pressure weighing chambers utilizes variable frequency control technology. Normally, the system uses the normal control mode, which meets most weighing requirements. For more demanding users, an optional LCD display and operator interface is available. This advanced configuration not only displays wind speed in real time, but also has setup and alarm functions. When the wind speed is out of the set range, the system will automatically sound an alarm, prompting the user to make the necessary adjustments. This intelligent control system greatly enhances the ease of operation and safety of the negative pressure weighing chamber.

The Neg Furls Negative Pressure Weighing Chamber is designed to provide a high cleanliness working environment to ensure the accuracy and safety of the weighing process. The system maintains negative pressure in the operating area through a series of advanced filtration and air circulation technologies, in compliance with pharmaceutical GMP standards.

The air in the room is initially purified by primary and intermediate filters. After that, the air is pressed by centrifugal fans into a static pressure box, and then passes through a high-efficiency filter for deeper purification. The air treated by the high-efficiency filter will be blown out evenly from the air outlet of the air diffusion air supply unit to form a uniform cross-section air velocity. In this way, clean air flows through the work area, ensuring a high level of cleanliness in the operating area.

To further enhance safety and accuracy, the center weighing hood of the Neg Furls Negative Pressure Weighing Chamber is maintained at negative pressure at all times. This design ensures that no contaminants escape during the weighing process, while exhausting approximately 10% of the recirculated air, increasing the stability and safety of the system.

The air in the center weighing chamber is self-circulating through a three-stage filtration system. This system includes a high-efficiency filter capable of removing 99.99% of particulate matter (≥0.3μm). This efficient dust removal ensures a clean operating environment that meets the strict GMP requirements of pharmaceutical companies.

The Neg Furls Negative Pressure Weighing Chamber provides a highly clean and safe weighing environment through multiple filtration and negative pressure design to meet the high standards required for pharmaceutical manufacturing.
