The Neg Furls Negative Pressure Weighing Chamber is an efficient and safe airflow control device designed for precision weighing and sampling. Its unique negative pressure system ensures air quality in the work area, protecting the operator and the product.

• Airflow Design

The negative pressure weighing chamber utilizes a vertical upward and sideways airflow design. The air enters the working area from above and flows from top to bottom, pressing the dust generated during the working process to the filtration device at the bottom of the side. The primary, secondary and bag-in-bag-out devices capture dust efficiently, and the air is pumped through the blower to the static pressure box of the high-efficiency filter. Part of the air is returned to the working area through the high-efficiency filter, and the other part is discharged to the outdoor through the exhaust filter, forming a stable negative-pressure environment.

• Component Structure

The weighing enclosure is precisely assembled from several parts, including the working area, the return air box, the fan box, the air outlet box and the outer box. The control panel is set in the front of the internal working area, and adopts Siemens touch screen inverter control system, which is convenient for the operator to control the starting and stopping of the blower and adjust the blower frequency to ensure the best running condition.

• Real-time monitoring and control

The control panel displays the differential pressure, wind speed, temperature and humidity of the primary, intermediate and high efficiency filters, and is equipped with a dust particle monitoring system to monitor the dynamic cleanliness in real time. The system is equipped with an abnormal alarm function. When the wind speed, differential pressure or cleanliness is out of the set range, the touch panel and auto-control box will issue an alarm to ensure the safety and cleanliness of the work area.

• Differential Pressure Monitoring

The weighing room is equipped with four differential pressure sensors, which monitor the resistance of homogeneous membrane, primary, intermediate and high-efficiency filters, and display the data in real time on the touch screen. When the differential pressure of the filter exceeds the set value, an alarm will be triggered to prompt the operator to carry out maintenance to ensure the efficient operation of the filtration system.

• Maintenance

The primary effect filter needs to be cleaned regularly according to the usage to maintain its filtration effect. A differential pressure gauge allows monitoring of the filter's pressure changes at different stages, providing a reliable indication of the weighing hood's lasting performance.

With its scientific design, precise monitoring and efficient filtration system, the Neg Furls Negative Pressure Weighing Chamber is the ideal choice for high cleanliness work environments, providing operators with a safe and secure workspace.

• Frequency Control
  

Neg Furls Negative Pressure Weighing Chambers are equipped with advanced inverter control technology. The default configuration is the normal control system, and the user can choose the LCD display and operation function. The LCD display not only shows the wind speed in real time, but also has the function of setting alarms to ensure the safety and stability of the operating environment.

• Lighting and Sterilization

The lighting system in the weighing room is well-designed to ensure that the illuminance is more than 300 Lux at one meter from the floor, providing sufficient working light. In addition, users can choose to install sterilization lamps or ozone generators for sterilization treatment, thus effectively ensuring the hygiene and safety of the operating environment.

• Filtration Systems

Neg Furls negative pressure weighing chambers utilize a highly efficient two-stage filtration system consisting of a primary filter and a high efficiency filter. The HEPA filters are DOP or PAO tested to ensure consistent and reliable filtration. All filters can be easily removed and replaced from the front or the top for easy maintenance.

• Differential Pressure Gauge

The weighing chamber is equipped with 2 differential pressure gauges as standard, which can monitor the pressure difference between inside and outside the chamber in real time to ensure the stability of negative pressure condition.

• Polymer equalization membrane

Negative pressure weighing chamber is equipped with polymer equalizing membrane, which significantly improves the uniformity of airflow and ensures the air quality of the working environment and the safety of operators.

Neg Furls Negative Pressure Weighing Chambers provide an efficient and safe working environment with superior materials and advanced technology. Whether you are weighing pharmaceuticals or other precision operations, Neg Furls is the ideal choice.

The Neg Furls Negative Pressure Weighing Chamber is a piece of professional laboratory equipment designed to provide an accurate weighing environment. The core principle of the weighing chamber is that the air is extracted from the chamber by means of a built-in pump, creating a negative pressure environment. This negative pressure effectively prevents interference from outside air currents and ensures that the weighing process is not affected, guaranteeing highly accurate results.

The negative pressure weighing chamber is designed so that the flow of outside air does not interfere with the stability of the balance when weighing trace amounts of substances. The efficient pumping system quickly establishes and maintains a stable negative pressure, allowing the lab technician to operate in an optimal environment.The Neg Furls Negative Pressure Weighing Chambers not only increase the accuracy of weighing, but also improve the overall efficiency of laboratory operations.

Widely used in chemical, pharmaceutical and other applications where precision weighing is required, Neg Furls negative pressure weighing chambers are an indispensable tool for ensuring the accuracy of experimental data due to their excellent performance and reliable operation.
