3.Features / Advantages
1). Modular design, simple and flexible installation.
2). Easy detachable airflow equalizing membrane, convenient to recondition.
3). Optional cooling parts: cooling coil ro system cooling air.
4). Gel seal HEPA, easy to pass leakage testing
5). Automatically tune fan frequency, assure the airflow speed is constant.
6). Pointer type differential pressure gauge, easy to monitor status of filters inreal-time.
7). Differential pressure alarm is convenient for replacing filters timely
8). Controlling with touchscreen, it is easy to use.
9). User's right is divided into two group: operator and administrator, so as to reduce mistake risk of modifying parameters
4.Working Principle
filtrated airborne particles from workspace air with fan, primary efficiency filter, medium efficiency filter and HEPA, negative pressure weighing booth supplies vertical unidirectional clean airflow to workspace. At the same, by venting 10-15% air volume, it achieve negative pressure between workspace and clean room, so as to prevent medical powder from spreading and raising. It can be tuned to run on constant fan frequency or air airflow speed by control system, which consists of PLC, air velocity transmitter and frequency converter.
