Neg Furls Negative Pressure Weighing Chamber Product Features in Detail

• Working area design

Material and structure: the working area is made of stainless steel 304, thickness is 1.2mm, the surface is processed by oil drawing short wire, the internal arc angle connection, no dead angle, not only ensure the sealing of the working area, but also enhance the overall neatness and aesthetics.

• Wind speed control

Manual frequency conversion system: Through the manual frequency conversion system, it can ensure that the wind speed in the main working area is always in the state of uniform operation, adapting to different weighing needs and ensuring the accuracy and stability of weighing.

• Filter differential pressure display

 Real-time monitoring: Equipped with a filter differential pressure display device, it can monitor the effective running condition of each filter in real time, which is convenient for timely detection and replacement of filters that are about to fail, ensuring the continuous and efficient operation of the equipment.

• Air duct design

Unique design: The unique air duct design effectively controls the working noise of the whole machine, provides a quiet weighing environment, and also reduces energy consumption, realizing the double optimization of environmental protection and practicality.

The Neg Furls Negative Pressure Weighing Chamber meets the stringent requirements of laboratories for high-precision weighing with its outstanding design and performance, not only guaranteeing a clean weighing environment, but also providing a convenient operating experience and efficient maintenance management, making it an indispensable and ideal choice for laboratories.

• Material Selection:

Neg Furls negative pressure weighing chambers are usually made of materials that meet national standards to ensure good corrosion, wear and high temperature resistance. Common materials are 304 or 316 stainless steel to suit different usage scenarios. In the absence of special requirements, the choice of material can be made according to the project budget, but it is recommended to choose a better quality material to facilitate long-term maintenance and use.

• Structural design:

The design of Neg Furls negative pressure weighing chambers focuses on structural rationality and durability. Its structure usually includes the working area, return air box, fan box, air outlet box and external box and other parts. The wall panels of the working area are made of stainless steel, and the internal rounded corners are connected without dead corners to ensure the sealing and neatness of the working area. The equipment adopts modular design, easy to assemble and disassemble on site, and has optional configurations such as PVC strip curtain on the front side.

• Filtration system:

The Neg Furls Negative Pressure Weighing Chamber is equipped with a highly efficient filtration system consisting of primary, intermediate, and high efficiency filters, as well as a homogenizing membrane. These filters effectively capture airborne particles to ensure clean air that meets GMP and other standards. Information such as differential pressure, air velocity and temperature and humidity of the filters can be monitored in real time through the control system to ensure the normal operation of the equipment.

• Control System:

The control system of Neg Furls Negative Pressure Weighing Room adopts advanced PLC control and touch screen operation, which can realize the functions of starting and stopping the fan and adjusting the wind speed. The system is also equipped with wind speed sensors, differential pressure sensors, etc. to monitor and adjust the status of the equipment in real time to ensure the stability of the weighing environment.

The core working principle of the Neg Furls Negative Pressure Weighing Chamber is its unique vertical unidirectional airflow design. This design allows part of the clean air to circulate within the working area, while the remainder is exhausted into the surrounding area, creating a negative pressure within the working area and effectively preventing the spread of contaminants and cross contamination. Specifically, the air is first pre-filtered through a primary filter to remove larger dust particles, then filtered through an intermediate filter for secondary filtration, and finally, under the pressure of a centrifugal fan, it passes through a high-efficiency filter to meet the cleanliness requirements and ensure the purity of the air.
