• High efficiency fan system:

The fan adopts advanced technology with the advantages of long life, low noise, maintenance-free and low vibration, which ensures the stability and reliability of the equipment during operation and reduces the maintenance cost.

• Double-layer negative pressure structure:

The equipment adopts a unique double-layer negative pressure structure design, which effectively prevents any risk of leakage and ensures the safety and reliability of the working environment.

• Excellent Air Uniform Distribution:

The negative pressure weighing chamber has excellent air distribution performance, ensuring uniform air flow in the chamber and avoiding any dead space, thus improving the precision and consistency of weighing.

• Adaptable to a variety of use environments:

The equipment is suitable for use in environments where the temperature ranges from 5℃ to 40℃, the relative humidity does not exceed 85% (no condensation), and it works normally under atmospheric pressure of 86KPa-106KPa. The power supply requirement is AC380V, three-phase, 50Hz, fully adapted to the needs of various industrial environments.

• High-quality box structure:

The box body is made of SUS304# sanded stainless steel, with a thickness of 1.0MM (other thicknesses are optional), with exquisite welding technology, all angles are fully welded without dead ends, and the surface treatment is free of welding traces, which ensures that the overall structure is firm and durable, and the appearance is beautiful.

With its excellent design and high quality materials, the Neg Furls Negative Pressure Weighing Chamber provides users with a safe, accurate and efficient weighing environment, making it an ideal choice for laboratory and industrial applications.

Neg Furls negative pressure weighing chambers are always designed and manufactured with the customer's needs in mind, constantly optimizing and upgrading the performance of our products to provide users with a safe, reliable and efficient working environment. We are committed to bringing every user a superior experience through high quality materials and advanced technology.

• Variable frequency control:

Neg Furls negative pressure weighing chambers come standard with a common control system, with an optional LCD display and operator interface available upon request. This optional system not only provides a real-time wind speed display, but also includes a programmable alarm function to ensure that abnormal conditions can be detected and dealt with in a timely manner under any circumstances, thus ensuring the safety and stability of the operating environment.

• Lighting / Sterilization:

In order to ensure that the working environment in the weighing chamber is well lit, the Neg Furls negative pressure weighing chamber has an illumination level of more than 300 Lux at one meter from the floor, which provides a good visual environment for the operator and reduces operating errors caused by insufficient light. In addition, customers can choose to equip with germicidal lamps or ozone generators to effectively kill bacteria in the air and on surfaces to maintain a clean operating environment.

• Sockets:

The Neg Furls 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 needs. This high level of protection not only prevents the intrusion of water and dust, but also meets the power needs of various equipment, ensuring the stability and safety of equipment operation.

In your capacity as the maker of the Negative Pressure Weighing Chamber, help me recreate an article about “Neg Furls Negative Pressure Weighing Chamber Product Working Principles Explained” based on the article below. And keep the word count to 400

The equipment uses a vertical unidirectional flow airflow form, the return air is first pre-filtered through a primary filter to dispose of the large dust particles in the airflow. After pretreatment, the air is then passed through the intermediate effect filter for secondary filtration, in order to play the role of fully protecting the high efficiency filter. Under the pressure provided by the centrifugal fan, it passes through the high-efficiency filter to meet the clean requirements. The operation area and the external environment form a relative negative pressure, so as to ensure that the dust in this area will not spread to the outdoors, and play a role in protecting the external environment.

This model weighing room adopts the structure of bag-in-bag-out replacement of G4 primary effect and F8 plate type intermediate effect, with the return air in the front of the operation area, and the front elevation of the personnel standing area as the mounting surface of the human-machine interface or buttons. This equipment is assembled by the work area, return air box, fan box, air box and the outer box of several large parts. The control panel is located in the front of the working area inside the equipment, and the control panel adopts light-touch LED control panel, which can control the starting and stopping of the fan, regulate the fan working condition, and adjust the wind speed needed in the working area (when the equipment is installed and used, it is necessary to regulate the working condition by the specialized personnel). There is a differential pressure meter next to it to test the resistance of the filter in the interior of the air supply box body and the exhaust air adjustment board, you can adjust the exhaust air volume of the equipment in a reasonable range (after the installation of the equipment in place, set up by professionals to test, please do not adjust without authorization)

In short, the working principle of both negative pressure weighing hood and negative pressure weighing chamber is based on negative pressure technology, by extracting the air inside the hood or the chamber to form a low-pressure environment, so as to realize the accurate weighing of goods. This type of weighing prevents items from evaporating, drifting or absorbing moisture and ensures the accuracy of the weighing results.
