• High-efficiency dust removal: through the three-stage filtration system, i.e. primary, intermediate and high-efficiency filters, particles are effectively removed to meet the requirements of GMP and other standards.

• Easy operation: Most negative pressure weighing chambers are equipped with a touch screen control panel, which is intuitive and simple to operate, and some of the equipment even supports remote control and data recording, which is convenient for management and traceability.

• Environmental protection and energy saving: Negative pressure weighing room can ensure cleanliness, but also to achieve the effective use of energy, such as the use of energy-saving fans and filtration systems to reduce unnecessary energy consumption.

• Modular design: easy on-site assembly and disassembly, convenient for transportation and future maintenance work.

• Product Materials and Construction
  

Neg Furls Negative Pressure Weighing Chamber is made of high quality stainless steel with good corrosion resistance and durability to adapt to a variety of complex working environments. Its structure mainly includes the working area, return air box, fan box, air outlet box and outer box and other components. The inside of the working area is made of smooth stainless steel with a seamless design to ensure the sealing and cleanliness of the equipment.

• Filtration System

The Neg Furls Negative Pressure Weighing Chamber is equipped with a highly efficient filtration system, including primary and high efficiency filters, which effectively intercept large and fine particles in the air to ensure the cleanliness of the air in the work area. The high efficiency filter meets the requirements of DOP or PAO test to ensure the filtration effect.

• Control System

The Neg Furls negative pressure weighing chamber is equipped with an advanced PLC control system combined with a touch screen operation, which simplifies the operation process and improves work efficiency. The control system is able to monitor the parameters such as differential pressure, wind speed, temperature and humidity of the filters in real time, and provide alarms and prompts for abnormal conditions, ensuring the stability and safety of the weighing process.

• Use and Maintenance

During the use of Neg Furls negative pressure weighing chamber, users should pay attention to the smooth placement of the equipment and the correct operation method to ensure the accuracy of weighing. For daily maintenance, the filter needs to be checked regularly and cleaned or replaced according to the usage to ensure the long-term stable operation of the equipment.

The air inside the negative-pressure weighing room passes through the primary and intermediate filters, then is pressed into the static pressure box by the centrifugal fan, and finally passes through the high-efficiency filter and then is blown out from the airflow diffusion air supply unit outlet surface to form a vertical unidirectional airflow to maintain the operation area in a negative-pressure state, and to discharge some of the recirculated air, so as to ensure the cleanliness and safety of the weighing environment.
