Weighing Booth

Product Description

A:  Overview

DB series weighing booths are used for the pharmaceutical, microbiological research and scientific experiments and other places of special local purification equipment. They are widely used in weighing and metering of raw materials, antibiotics sampling, hormone drugs treatment (either powders or liquids).

Through effect filter and HEPA filter, air is pushed by DB series weighing booth from the centrifugal fan to plenum chamber, then flows out through HEPA filter, forming a vertical unidirectional flow to protect operators and prevent contamination of drugs. Weighing booth’s operating area discharges 10% of the circulating air to maintain the negative pressure to prevent pollution of the environment and pharmaceutical cross-contamination.

Design reference:

1, the pharmaceutical industry standards

2, China GMP (2010 version) standard

3, EU GMP standards

4, FDA regulations and the latest CGMP guidelines

B:  Characteristics

C:  Configuration descriptions

1, high-end configuration

1) Filter: filtered through primary, secondary and HEPA filter. HEPA filter tank (efficiency 99.995% -99.999% @ 0.3um) can meet the DOP or PAO test requirements;

2) Pressure gauge sender: DWYER (3 pieces, 0 ~ 500pa, 0 ~ 250pa and 0 ~ 60pa respectively)

3) Wind speed sensor: E+E or Kai mao;

4) Current polymer film: significantly improve the degree of uniformity of wind speed in surface;

5) PLC control: LCD (Siemens) controls speed and lighting, the screen can display real-time surface wind speed, real-time differential pressure before and after the filters, beep will alert when the wind speed and pressure value exceeds the set range;

6) Illumination: In the surface (one-meter distance to ground) of weighing cover, illuminance is greater than 300Lux;

7) Weighing bench: used to place the electronic balance and fill out the recording (optional)

8) Socket: waterproof and dustproof socket configuration, grade: IP66. Number configured according to customer demand.
