• Automatic constant or stepwise adjustment of the air velocity

Neg Furls Negative Pressure Weighing Chambers are equipped with an advanced air velocity control system that allows for automatic constant or stepwise adjustment of air velocity. This design ensures a stable weighing environment, which is essential for accurate weighing processes. The user can choose the appropriate air velocity setting for different weighing requirements to achieve optimal weighing results.

• Liquid Tank Design Ensures Perfect Sealing

Neg Furls negative pressure weighing chambers utilize a liquid tank design that ensures a tight seal between the chamber and the outside environment, avoiding the risk of potential contamination. This design not only ensures a clean weighing environment, but also improves the overall sealing performance and extends the service life of the equipment.

• Consistency inside and out, no dead space

The Neg Furls Negative Pressure Weighing Chamber has been designed to be consistent inside and out, ensuring that the interior space of the weighing chamber is clean and free from dead space. This design reduces the accumulation of dust and microorganisms, facilitates routine cleaning and maintenance, and meets the stringent cleanliness requirements of GMP standards.

• The chamber construction is made of SUS304.

Neg Furls negative pressure weighing chambers are constructed of SUS304# sanded stainless steel with a thickness of 1.0MM sanded plate to ensure robustness and durability. Stainless steel has good corrosion resistance, making it suitable for use in wet or chemical environments, as well as being easy to clean and maintain.

• Welding is smooth, with full angles and no dead spots.

The Neg Furls Negative Pressure Weighing Chambers are welded in such a way that all welded areas are smooth and have no weld marks. This not only enhances the appearance of the unit, but also ensures that the chamber is sealed and clean, avoiding contamination in dead corners.

• Surface finish without weld marks

The Neg Furls Negative Pressure Weighing Chamber has a weld-free surface finish that ensures an overall aesthetic and functional appearance. This not only enhances the visual appearance of the unit, but also reduces the risk of potential contamination caused by welding, meeting the high standards required in a weighing environment.

• Material Description

Neg Furls negative pressure weighing chambers are typically made from high quality stainless steel materials such as 304 or 316 stainless steel to ensure adequate robustness and corrosion resistance. This material is not only easy to clean, but also resistant to a wide range of chemicals, making it particularly suitable for handling potentially corrosive chemicals.

• Components

The core components of the Neg Furls Negative Pressure Weighing Chamber include the work area, the return air box, the fan box, the discharge air box and the outer box. In addition, primary filters, intermediate filters, high-efficiency filters and variable air volume fan units are included to form a complete purification system.

• Control and Monitoring

Neg Furls Negative Pressure Weighing Chamber is equipped with advanced PLC control system, which can realize the precise adjustment of fan working condition and ensure the stability of air speed, differential pressure and other parameters. At the same time, monitoring equipment such as differential pressure sensors and wind speed sensors can monitor the operating conditions of the weighing chamber in real time to ensure the accuracy of the weighing process.

• Lighting and Sterilization

The weighing room is equipped with sufficiently bright lighting equipment, usually the illumination of one meter on the ground is more than 300 Lux, to meet the visual needs of weighing work. In addition, it is equipped with sterilization equipment, such as ultraviolet germicidal lamps or ozone generators, to maintain the cleanliness of the weighing environment.

The Neg Furls Negative Pressure Weighing Chamber utilizes a vertical unidirectional airflow, where the air is drawn in by a fan, passed through a primary filter to remove larger particles, further purified by an intermediate filter, and finally passed through a high efficiency filter to deliver clean air. This process ensures a negative pressure environment in the work area and prevents contaminants from escaping.
