The DB series weighing room is a specialized local purification equipment used in pharmaceutical, microbiological research, and scientific experiments. It is widely used for weighing and measuring raw materials, sampling antibiotics, and processing hormone drugs, regardless of whether the drugs are powder or liquid.
The DB series weighing room passes the air through the primary and intermediate efficiency filters, and is compressed into the static pressure box by a centrifugal fan. After passing through the high-efficiency filter, the air flow is diffused to the outlet surface and blown out, forming a vertical unidirectional air flow to protect operators and prevent drug contamination. The operating area of the weighing hood discharges 10% of the circulating air and maintains a negative pressure state to avoid environmental pollution and cross contamination of drugs.

Design reference basis:
1. Pharmaceutical Industry Standards
2. Chinese GMP (2010 Edition) Standard
3. EU GMP standards
4. FDA regulations and latest CGMP guidelines
Performance characteristics:
1. The box is made of high-quality SUS304 stainless steel, which is easy to clean;
2. Top air supply, high-efficiency filter efficiency ≥ 99.99% @ 0.3um, purification level in the operating area higher than room cleanliness;
3. Frequency converter adjusts the wind speed of the fan;
4. Button control lighting and power supply;
5. Install a differential pressure gauge to monitor the usage of the filter;
6. Installing a DOP testing port can effectively detect the integrity of high-efficiency filters;

7. The modular design of the box sampling can be disassembled and assembled on-site.

Configuration description:
1. High end configuration
(1) Filter: primary, intermediate, and high-efficiency filters, with a liquid tank high-efficiency filter (efficiency: 99.99%~99.999% @ 0.3 μ m) Can meet the testing requirements of DOP or PAO;
(2) Differential pressure sensor: DWYER
(3) Wind speed sensor: E+E or Kemao
(4) Polymer flow equalization membrane: significantly improves the uniformity of wind speed on the outlet surface;
(5) PLC control: The LCD screen controls wind speed and lighting, and the screen can display real-time wind speed and pressure difference before and after various filters. When the wind speed and pressure difference values exceed the set range, the buzzer can emit an alarm sound;
(6) Illumination: The average illumination on a plane one meter above the ground inside the weighing hood is greater than 300Lx;
(7) Weighing table: for placing electronic scales and filling in records (optional);
(8) Socket: Equipped with waterproof and dustproof socket, grade: IP66. The quantity is configured according to customer needs.
