Airtech powder dispensing booth mixed unidirectional airflow system has been specially designed for product sampling, dispensing and bulk drug canister filling. This equipment minimizes the risk of contamination of work zone and ensures health safety for person working with chemical/ powder. Based on the re-circulation of air this ensures that the cloud formed by the material dispensed, is sucked in a natural pattern of movement and arrested through pre filter. Then this air is supplied back to work zone through HEPA filters.
