Neg Furls Negative Pressure Weighing Chambers provide an efficient and safe weighing environment with their superior design and advanced technology. The following are its main product features:

• Consistency inside and out, no dead space

The Neg Furls Negative Pressure Weighing Chamber has an integrated design with no dead space inside or out, ensuring a clean and easy to clean environment. This design not only enhances the aesthetics of the equipment, but also greatly reduces the risk of contaminants being left behind, ensuring the reliability of the process.

• Manual inverter system for wind speed

In order to ensure that the air velocity in the main working area is always uniform and stable, the Neg Furls Negative Pressure Weighing Chamber is equipped with a state-of-the-art manual inverter system for air velocity. Users can manually adjust the wind speed as needed to ensure smooth airflow during weighing, effectively preventing interference from outside air and improving the accuracy of weighing.

• Filter Differential Pressure Display

Neg Furls negative pressure weighing chamber is equipped with a filter differential pressure display device to monitor the operation status of each filter in real time. By displaying the differential pressure data of the filters in real time, users can understand the working condition of the filters in time to ensure the effective operation of the filtration system, which further guarantees the cleanliness and safety of the laboratory environment.

• Unique air duct design

The weighing chamber adopts a unique air duct design, which effectively controls the working noise of the whole machine. By optimizing the air duct structure, it reduces the resistance and turbulence of the airflow inside the equipment and lowers the noise level during operation, providing a quiet and comfortable working environment for users.

In short, Neg Furls negative pressure weighing chambers are ideal for laboratory weighing work thanks to their neat design with no dead space, adjustable air velocity system, real-time monitoring of the filter differential pressure display device and noise-reducing air duct design. Whether it's safety, stability or comfort, Neg Furls has what you need to make your lab work more efficient and accurate.

Neg Furls Negative Pressure Weighing Chambers provide a safe and reliable environment for a wide range of precision weighing and experimental operations due to their superior design and quality materials. Key materials and components are described in detail in this article.

• Filtration System:

Neg Furls negative pressure weighing chambers utilize a two-stage filtration system to ensure that air quality standards are met. Primary filters are used to retain larger particles, while high efficiency filters are used to capture fine particles to meet DOP or PAO testing requirements. Both filters can be easily removed and replaced from the front or the top, ensuring easy and efficient maintenance.

• Differential Pressure Gauges:

The negative pressure weighing chamber is equipped with two differential pressure gauges to monitor the pressure difference between the inside and outside in real time to ensure stable operation under negative pressure. This not only helps to maintain a clean environment in the weighing chamber, but also prevents contaminants from escaping and ensures operator safety.

• Polymer flow homogenizing membrane:

In order to further improve the uniformity of air flow, Neg Furls negative pressure weighing chambers are equipped with a polymer equalization membrane. This material significantly improves the uniformity of the air flow and avoids localized high or low air velocities, thus improving the overall accuracy and reliability of the operation.

Overall, the Neg Furls Negative Pressure Weighing Chamber has been carefully selected and configured with high quality materials and components to ensure that it performs well in a wide range of precision operations. This not only provides an ideal environment for experimentation and production, but also greatly improves efficiency and safety.

The Neg Furls Negative Pressure Weighing Chamber utilizes an advanced vertical unidirectional airflow design to ensure high cleanliness in the operating area and protection of the external environment. The principle of operation is as follows:

• The air is pre-filtered through a primary filter. This step effectively removes large particles of dust from the airflow and ensures a smooth subsequent filtration process. After primary filtration, the air passes through the intermediate filter for secondary filtration. The main purpose of this layer of filtration is to protect the high-efficiency filter, thereby extending its service life and improving the overall filtration efficiency.

• Under the pressure provided by the centrifugal fan, the air passes through the high efficiency filter for final filtration. This step ensures that tiny particles are completely removed from the air, allowing the operating area to meet stringent cleanliness requirements.

• The Neg Furls Negative Pressure Weighing Chamber is designed so that the operating area is negatively pressurized relative to the outside environment. This negative pressure ensures that dust in the operating area does not escape to the outside, thus protecting the outside environment from contamination.

• The Neg Furls Negative Pressure Weighing Chamber is ideal for ensuring dust control and environmental safety through multi-stage filtration and negative pressure control, achieving the dual goals of efficient cleanliness and environmental protection.
