Campânula de fluxo laminar com filtro Hepa para a indústria farmacêutica

Negative pressure laminar flow measuring hood in pharmaceutical workshop

1. Laminar flow measuring hood description

Laminar flow measuring hood product introduction and use conditions
1), the use of laminar flow measuring hood
Laminar measuring hoods are widely used in areas where local cleansing is required. Laboratory, biopharmaceutical, optoelectronics industry, microelectronics, hard disk manufacturing and other fields. Laminar flow hoods have the advantages of high cleanliness, connectivity to assembly lines, low noise, and mobility. Laminar flow hoods can be operated bilaterally with high utilization.

2), Laminar flow measuring hood the use of the environment and conditions
Temperature 5°C~40°C
Relative humidity not more than 85% (non-condensing)
Atmospheric pressure 86kPa~106kPa
Power supply AC220V, single phase, 50

Introduction:

Negative pressure measuring hood provide containment by utilizing high velocity air to capture air borne dust particles. Control exposure risk to hazardous materials for a wide variety of equipment and processes. Protecting the operator during sensitive tasks, this complied with GMP practices.

Applications: Negative pressure measuring hood subdivision of powder of liquids, charging and offloading materials to reactors, fluid bed dryers, granulators, filter dryers, glass ware skids in cleanrooms and so on.

Operating Features:

1: Negative pressure measuring hood modular. Easy-to clean rigid design with minimal joints

2: HEPA/ULPA Gel-seal down flow filter are replaceable from within the booth.

Gel-seal is more reliable than conventional gasket seals

3: Voltage-compensating blowers ensure stable air flow.

4: Magnehelic Gauges provide convenient and reliable means for monitoring

gauges air flow and filter condition.

5: Containment performance verified according to the ISPE good practice guide,

assessing the particulate containment performance of pharmaceutical equipment.

2.Measuring hood structure

1). The measuring hood is made of SUS 304 stainless steel plate;

2). Top configuration tank HEPA air filter;

3). At the bottom of the weighing hood, configure the primary and middle efficiency air filter;

4). Weigh the top of the chamber and configure a uniform flow membrane to make the wind blow evenly.

5). Internal configuration high power low noise centrifugal fan;

6). The weighing hood is equipped with two differential pressure gauges for monitoring the pressure difference of the intermediate efficiency air filter/the pressure difference of the high efficiency air filter;

7). The weighing hood is equipped with a lifting table;

8). The overall structure of the weighing hood is split type, which can be assembled on site;
