Negative-pressure Dispensing Booth
OVERVIEW
The negative-pressure dispensing booth is suitable for weighing, sampling, filling, dispensing and other operations for highly active and toxic products and APIs, mainly to provide one-way air flow to remove dust during weighing process and maintaining the negative-pressure environment for the material weighing area to ensure the high cleanliness in the working area, thus preventing dust inhalation risk to human body and cross contamination. The product operation area can reach the level of OEB 5/6.

FEATURES

The main structure of equipment is made of stainless steel, with beautiful elegant appearance and polished bright surface. It is easy to clean;

The double-layer safety glass window is installed at the left side of working bench, facilitating light collection and operation;

The PLC and HMI are used for automatic electric control with frequency control of air flow;

The unique principle of independent ventilation in three zones achieves the isolation of operation area from the external environment by using the air curtain;

Operators are outside the operation area to avoid airflow disturbance and prevent harmful substances to invade human body and environment;

The machine requires less air flow, which reduces energy consumption and prolongs service life of filter. Noise ≤ 70db;

The air flow velocity at the operation area is as low as 0.1-0.4m/s to ensure the operation precision;

The handling and cleaning area is relatively small, and thus the machine can be easily maintained and cleaned;

The fewer filters and filters of smaller volume are adopted to reduce the maintenance costs;

The flow detector of the exhaust/circulation airflow is equipped with the alarm apparatus, so that the abnormal airflow speed will cause the sound and light alarm.
