Dispensing booth is a kind of purifying equipment for materials sampling, weighing, and analysis.
Dispensing booth is also called a sampling booth, a weighing booth, a downflow hood, RLAF (reverse airflow), on a powder containment booth.
It uses the laminar airflow technique with the aim of providing dust containment and operator protection while hlling, weighing. and sampling harmful components. active ingredients and raw powder materials. Dispensing booth provides a unidirectional airflow (Laminar airflow in which most of the clean air enters the working zone.
Only a small amount of the air is discharged to the ambient environment, which creates negative pressure in the working zone, thereby providing a safe and clean working environment, and preventing the operators from powder contamination.
Product Detail
Structure
1). The weighing chamber is made of SUS 304 stainless steel plate; 2). Top configuration tank HEPA air filter; 3). At the bottom of the weighing chamber, 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 chamber 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 room is equipped with a lifting table; 8). The overall structure of the weighing chamber is split type, which can be assembled on site;
Working Principle
The fan will suck and pull the air to HEPA filter(H14 HEPA filter),which captures the dust and particles. The HEPA filtered air will be distributed in unidirectional form into the working zone. The downflow of air will carry the dust generated during powder processing into a pre-filter.After pre-filtered, the air will go through a fine filter (F8 filter) and is typically re-circulated. + The HEPA-filtered air is divided into 2 parts. -90% of the air flows through a diffuser and forms a vertical laminar flow into the working zone -10% of HEPA filtered air is bled out of the booth through the air outlet to maintain the working zone under negative pressure, minimizing airborne contamination breakout
Features:
*Negative pressure design prevents the powder from escaping out of the working zone *Unidirectional airflow provides a superior aseptic working area *Stainless steel SUS 304 structure with rounded corners makes dispensing (sampling or weighing) booth hygienic and easy to clean *Smart LCD control display ensures the proper performance of the booth *The maximum noise level of below 65 dB *Differential pressure gauges are equipped to monitor the integrity of the filters.
*PVC curtain or air curtain increases the containment efficiency *Dispensing booth design according to GMP guidelines
