The Neg Furls Negative Pressure Weighing Chamber is a high-end unit designed for precision weighing and laboratory safety. Its outstanding features guarantee the user optimum performance and safety during the weighing process.

•  Neg Furls negative pressure weighing chambers are equipped with automatic constant or stepwise adjustment of the air velocity. Whether for rapid weighing or long periods of time, the system automatically adjusts the air velocity to ensure that the air flow in the operating area is always optimized. This not only improves the accuracy of weighing, but also effectively reduces the influence of the external environment on the experimental results.

•  The tank design of the negative pressure weighing chamber ensures a perfect seal. The unique tank structure prevents any leakage of gas or particles, ensuring a clean and safe working environment. This design not only increases the reliability of the equipment, but also greatly reduces the frequency of maintenance and cleaning, allowing the user to concentrate on the experiment itself.

•  The Neg Furls Negative Pressure Weighing Chamber is consistent both inside and out, with no dead space. The entire unit is constructed from high quality materials, with smooth surfaces inside and out, ensuring that there are no dead spots for dust or contaminants to accumulate. This design not only facilitates cleaning and maintenance, but also greatly enhances the overall aesthetics and durability of the unit.

•  The equipment is also equipped with a manual frequency conversion system for wind speed, so that the wind speed in the main working area is always in a uniform operating state. Users can manually adjust the air speed according to their specific needs, thus obtaining the best air circulation effect in different operating environments. This feature not only increases the flexibility of the unit, but also significantly enhances the user experience.

In summary, Neg Furls negative pressure weighing chambers are indispensable in the laboratory sector due to the automatic and stepwise adjustment of air velocity, the perfectly sealed tank design, the consistent and clean structure inside and out, and the manual inverter system for air velocity.

When you choose Neg Furls, you choose an efficient, safe and reliable working partner.

Neg Furls Negative Pressure Weighing Chambers are designed and manufactured with a focus on high quality and performance to ensure that they meet the needs of a wide range of demanding laboratory and industrial applications.

• Chamber Materials

The entire chamber is made of high quality SUS304 stainless steel, precision bent, welded and assembled to ensure a high degree of flatness. This material is not only corrosion-resistant and has a long service life, but is also easy to clean and maintain, providing users with a safe and hygienic working environment. The design of the electrical cabinet is flexible, and it can be built-in or external according to the need, which is convenient for customers to configure according to the actual application.

• Polymer equalization membrane

The negative pressure weighing chamber is equipped with polymer equalization membrane, which significantly improves the uniformity of the air outlet. This polymer material can effectively control the distribution of airflow and ensure stable air flow in the negative pressure environment, thus providing a more accurate and safer operation space.

• Frequency Control System

The weighing chamber is equipped with an advanced inverter control system, which allows users to choose between the normal control mode or the advanced control mode equipped with LCD display and operation functions. The advanced control system not only displays the wind speed, but also has real-time setting and alarm functions, which enhances the convenience and safety of use.

• Lighting and Sterilization

The lighting design in the weighing room takes into full consideration of the user's needs and ensures that the illumination at one meter from the ground reaches more than 300 Lux. Sterilization function can be equipped with germicidal lamp or ozone generator, providing a variety of options to ensure the cleanliness and safety of the laboratory environment.

• Socket Configuration

In order to meet the needs of different customers, the Negative Pressure Weighing Chamber is equipped with waterproof and dustproof industrial sockets, the number of which can be customized according to the customer's specific requirements, ensuring the safety and reliability of the power supply.

In short, Neg Furls negative pressure weighing chambers are designed to provide an efficient, safe and reliable working environment with superior materials and advanced design.

The Neg Furls Negative Pressure Weighing Chamber provides the user with a high level of cleanliness through an advanced air filtration and circulation system that works as follows:

  First, the air in the weighing chamber is initially purified by primary and secondary filters, and then pressed by centrifugal fans into a static pressure box. Immediately afterward, the air passes through the high-efficiency filter, enters the airflow diffusion air supply unit, and is blown out evenly from the air outlet surface. The clean air flows through the work area at a uniform sectional air velocity, ensuring a high degree of cleanliness in the work area.

  The operating area of the center weighing hood is always kept under negative pressure while 10% of the circulating air is discharged. The air in the weighing compartment is self-circulating through a three-stage filtration system containing high-efficiency filters capable of removing 99.99% of particles (≥0.3μm). This design is fully compliant with GMP (Good Manufacturing Practice) requirements for pharmaceutical companies.

  Under the pressure provided by the centrifugal fan, the air passes through the high-efficiency filter to achieve cleanliness. Negative pressure is created between the operating area and the outside environment, thus ensuring that dust in this area does not spread to the outside, effectively protecting the outside environment.

The Neg Furls Negative Pressure Weighing Chamber not only provides a safe and clean working environment, but also prevents the ingress of external contaminants, ensuring that experimental and production processes are efficient and safe. The design and operating principle of this system ensures that it can be used in a wide range of applications such as pharmaceutical manufacturing and other high-cleanliness requirements.
