• Automatic Constant or Stepwise Adjustment of Air Velocity

The air velocity can be adjusted according to the actual needs by means of an automatic constant or stepwise adjustment function, in order to adapt to different weighing requirements.

• Liquid tank design ensures perfect sealing

The liquid tank design in Neg Furls negative pressure weighing chambers prevents spillage of liquid or solid reagents and ensures an airtight weighing environment.

• Consistency inside and out, no dead space

The simple design of the internal structure of the equipment, with no unnecessary dead space, makes it easy to clean and maintain, and also ensures the cleanliness of the weighing environment.

• Manual frequency conversion system for wind speed

The manual frequency conversion system allows the operator to manually adjust the wind speed according to the actual situation in order to achieve the best weighing effect.

Filter Differential Pressure Indicator

The filter differential pressure display device monitors the operating condition of the filter in real time, ensuring real-time monitoring and maintenance of the weighing environment.

• Unique air duct design

Neg Furls negative pressure weighing chambers have a unique air duct design that effectively controls noise during operation and provides a quiet weighing environment.

Main working area with equalized flow design

The main working area of the machine is designed with equalized flow, which can effectively control the spillage and uplift of dust and reagents to protect the operator and the environment.

• Chamber Material

Neg Furls Negative Pressure Weighing Chambers are constructed from high quality SUS304 stainless steel, a material with excellent corrosion resistance and durability that can withstand a wide range of laboratory environments and ensure long term stability. The chambers are precision bent, welded and assembled to ensure a sturdy and level structure for easy cleaning and maintenance.

• Polymer homogenizing membrane

Neg Furls Negative Pressure Weighing Chambers are equipped with a polymer equalization membrane that effectively improves the uniformity of the airflow, ensures consistent air velocity in the working area, and provides stable environmental conditions for experiments. The design of the membrane helps to distribute the air evenly and avoid turbulence, thus protecting the accuracy of the experimental process.

• Filtration Systems

The Neg Furls Negative Pressure Weighing Chamber utilizes a two-stage filtration system consisting of a primary filter and a high-efficiency filter to meet DOP or PAO testing requirements. The design of the filtration system balances filtration efficiency with ease of replacement, making it easy to remove and replace the filter from the front or the top, ensuring ease of operation and safety.

• Differential Pressure Gauge

The Differential Pressure Gauge is an integral part of the Neg Furls Negative Pressure Weighing Chamber. It monitors the resistance of the filters in real time and provides the operator with accurate differential pressure information to help determine if the filters need to be replaced and to ensure the continuous and efficient operation of the weighing chamber.

• Frequency Control

The Neg Furls Negative Pressure Weighing Chamber supports variable frequency control, which allows the operator to adjust and monitor the air speed through the LCD display, realizing precise control of the air speed in the working area. This feature is essential to ensure the stability of the lab environment.

• Lighting and Sterilization

The Neg Furls Negative Pressure Weighing Chamber is well illuminated with more than 300 Lux, ensuring that the operator is able to carry out weighing operations in a bright environment. Sterilization options, such as UV germicidal lamps or ozone generators, eliminate airborne microorganisms and provide a cleaner environment for experiments.

• Weighing Stands and Sockets

The Neg Furls Negative Pressure Weighing Chamber is equipped with a weighing table for weighing utensils and waterproof and dustproof industrial sockets to provide a safe power supply for different types of equipment.

Negative pressure weighing room adopts vertical unidirectional flow airflow form, the air is first pre-filtered through the primary filter to remove larger particles of dust particles, and then through the intermediate filter for secondary filtration, and finally under the pressure of the centrifugal fan, most of the air is blown vertically through the high-efficiency filter to the working area, and a small portion of the air is discharged through the external high-efficiency filters to the indoor, so as to form a negative pressure in the working area. This ensures the cleanliness of the operating environment.
