• Fan system: long-life, low-noise, maintenance-free, low-vibration fans are used to ensure stable operation for a long time.

• Double-layer negative pressure structure: the unique double-layer design effectively avoids the risk of leakage and ensures the sealing of the internal environment.

• Excellent performance of even air distribution: well-designed air duct system ensures even air distribution in the whole working area.

• Air speed adjustment: The air speed can be adjusted by automatic constant or stepwise adjustment to meet different experimental requirements.

• Liquid Tank Design: Unique liquid tank design ensures perfect sealing effect and prevents any possible contamination.

• Consistency of internal and external structure: The internal and external structure is designed to be neat and free of dead corners, which is easy to clean and maintain.

• Wind speed frequency conversion system: manual wind speed frequency conversion system ensures that the wind speed in the main working area is always uniform.

• Filter differential pressure display device: real-time monitoring of the operating conditions of each filter channel to ensure filtration efficiency.

• Unique air duct design: effectively control the working noise of the whole machine and provide a quiet working environment.

• Even flow design: Even flow design in the main working area controls the spillage and upward movement of dust and reagents to protect the operator and the environment.

• Operation area protection: Hundred levels of vertical laminar flow protection, in line with international standards ISO 5 (NF, EN, ISO 14644-1).

• Use of the environment and conditions: suitable for temperature 5 ° C - 40 ° C, relative humidity is not greater than 85% (non-condensing), the atmospheric pressure of 86kPa-106kPa environment, the power supply AC380v, three-phase, 50HZ.

• Box material: made of SUS304# sanded stainless steel, thickness 1.0MM, to ensure the stability and durability of the structure.

• Box: the whole is made of SUS304 stainless steel bending, welding, assembling, with high flatness and excellent cleaning convenience.

• Polymer equalization film: installed on the air outlet surface, it can significantly improve the uniformity of the air outlet, and the uniformity of wind speed is controlled within 5%-10%.

• Filter: including primary filter and high efficiency filter, meets DOP or PAO test requirements, can be disassembled and replaced from the front or above.

• Differential Pressure Gauges: Two differential pressure gauges are provided to monitor changes in filter resistance.

• Illumination / Sterilization: Internal illumination of greater than 300 Lux, sterilization options include UV lamps or ozone generators.

• Weighing table: for holding weighing tools, optional.

• Sockets: Waterproof and dustproof industrial sockets are provided, the number of which is configured according to customer requirements.

Negative pressure weighing room adopts vertical unidirectional flow airflow form, the return air is first pre-filtered through the primary filter to remove large particles of dust particles, and then filtered through the secondary filter of the intermediate filter, and finally under the pressure of the centrifugal fan, the clean air will be sent back to the indoor workspace through the high efficiency filter, and the rest of it will be discharged outside through the external high-efficiency filters, to keep the operation area and the external environment in a negative-pressure state, to prevent the dust from spreading to the outside, to protect the environment. The negative pressure between the operation area and the external environment is maintained to prevent dust from spreading to the outdoor area and protect the environment.
