Neg Furls Negative Pressure Weighing Chambers are ideal for modern laboratory and industrial weighing due to their superior design and advanced technology. The following are its main product features:

• Double Negative Pressure Structure: The double negative pressure design ensures no risk of leakage and provides the highest level of safety. Both hazardous chemicals and fine powders can be operated in an absolutely safe environment.

• Manual Frequency Conversion System for Wind Speed: Equipped with a manual frequency conversion system for wind speed, it ensures that the wind speed in the main working area always maintains a uniform operation. This not only improves the accuracy of weighing, but also guarantees the safety of the operator.

• Filter Differential Pressure Display Device: Real-time monitoring of the operating status of each filter channel, through the filter differential pressure display device, the user can always understand the working condition of the filter to ensure that the air quality is always in the best condition and prolong the service life of the equipment.

• Unique air duct design: The innovative air duct design effectively controls the working noise of the whole machine, providing users with a quiet and comfortable working environment. Even if it is used for a long time, it will not affect the operator's working efficiency and health.

Neg Furls negative pressure weighing chambers, with their sophisticated design and reliable performance, are widely used in a variety of weighing operations that require strict protection. Choose Neg Furls for the perfect combination of safety and efficiency.

Neg Furls Negative Pressure Weighing Chambers utilize advanced materials and designs to ensure an efficient and safe operating environment. Below is a description of the main materials used in this product:

• Polymers: The air outlet side of the weighing chamber is made of polymer homogeneous membrane:

The airflow surface of the weighing chamber is made of polymer equalizing film, which can ensure the air velocity uniformity is controlled between 5% and 10%, providing stable airflow distribution, effectively reducing eddy currents, and improving weighing accuracy and operating comfort.

• Filter:
  We use a two-stage filtration system, including primary filters and high-efficiency filters. The HEPA filters strictly comply with DOP (Dioctyl Phthalate) or PAO (Polyalphaolefin) test standards to ensure excellent filtration performance. The filters are designed to be easy to disassemble and replace from the front or the top as needed, ensuring that the unit is always in optimal working condition.

• Sockets：

The Negative Pressure Weighing Chamber is equipped with waterproof and dustproof industrial sockets, the number of sockets can be flexibly configured according to the customer's needs, to meet the power needs of different equipment, to ensure safety and convenience.

Neg Furls negative pressure weighing chambers are carefully selected and designed to provide users with an efficient and reliable weighing environment that meets the needs of a wide range of demanding applications.

The Neg Furls Negative Pressure Weighing Chamber is a localized decontamination unit designed for pharmaceutical and microbiological research and scientific experiments. In this article, we will briefly describe its principle of operation to help users better understand and apply the equipment.

The Negative Pressure Weighing Chamber utilizes a vertical unidirectional airflow. Its workflow is as follows:

• Primary filtration: the air first passes through the primary filter to remove large particles of dust.

• Intermediate-effect filtration: The air after pretreatment enters the intermediate-effect filter for secondary filtration to protect the subsequent high-efficiency filter.

• High-efficiency filtration: Under the pressure provided by the centrifugal fan, the air passes through the high-efficiency filter to meet the cleanliness requirements.

The relative negative pressure between the operation area and the external environment ensures that the dust in the operation area will not spread to the outside, thus protecting the external environment.

With this three-stage filtration and negative pressure control, the Neg Furls Negative Pressure Weighing Chamber ensures a clean and safe laboratory environment.
