What is Dispensing Booth?
A dispensing booth is also called a sampling booth or weighing booth. It is a unique clean air system popularly used in the pharmaceutical, chemical and food sectors. It has a unique design to safely handle powders or raw materials while weighing, mixing, transferring or sampling items. Additionally, it is also useful to handle granules and active pharmaceutical ingredients (APIs). One can easily find a dispensing both inside clean rooms where hygiene, safety and precision is most important. The booth keeps airborne particles from spreading so it protects the operator from breathing them in. Besides, the product stays free from contamination.
What Does It Look Like?
A dispensing booth is a stainless steel enclosure. It has:
● A front opening for easy access
● Transparent side panels for visibility
● Bright and no shadow lighting● Control panels to monitor airflow and filters
Role of Airflow in Dispensing Booth
What makes a dispensing booth effective is its air flow system. Clean air enters the booth from the top. It passes through HEPA filters. HEPA filters can trap 99.97% of dust, microbes, and tiny particles. Once filtered, the clean air flows downwards in a steady and vertical stream. This keeps the work area free from contamination. This type of movement is called laminar air flow. It plays a crucial role because it sweeps dust particles away from the breathing zone.
At the lower back or base of the booth, exhaust vents pull the contaminated air out. A portion of this air is filtered and recirculated. Where as the additional filters safely expels the rest. This constant movement of air creates a safe working environment inside the booth.
In some setups, the booth maintains negative pressure. Hence, it means air always flows into the booth, never out. This ensures that no contaminated air escapes into the surrounding cleanroom.
Why Is Dispensing Booth Important?
If you’re running a pharmaceutical facility, the dispensing booth is not a luxury but a necessity. We have mentioned the reasons below.
● For the operator: It reduces exposure to harmful powders and allergens.
● For the product: It keeps it safe from outside contaminants.
● For the process: It ensures batch after batch consistent quality.● For compliance: It helps meet GMP, WHO, US FDA, and EUGMP requirements.

Dispensing Booth Design
The body is of stainless steel (SS304/SS316). The design includes vertical laminar airflow with three-stage filtration: pre-filter, fine filter, and HEPA filter. It has bright lighting (800–1000 lux), low noise (<65 dBA), anti-static PVC curtains. Moreover, it has simple control switches. One can easily find it in different size range from 3 to 6 feet wide. Smaller booths work great for basic sampling tasks, while larger ones are used for high-volume weighing and batch processing. Some models offer optional UV lights and pressure gauges.
