The Powder Dispensing Sampling Booth which we offer are used for protecting the work area from the contamination by dispensing powder & chemicals. The equipment also takes care for the health of the workers working under laminar air flow. These equipment are based on 3 levels of filtration of air circulation that ensures that cloud or particles formed by material dispensed is sucked by the filters. The use of magnehelic gauges also help in indicating the pressure difference between the filters. During the initial operation cycle, we have successfully achieved class 100 airs with velocity 0.45m/s +/- 20% below working area. Features: Air curtain PVC curtains provided Internal coving provided DOP port up stream provided Pre filter eff. 95% Intermediate filter efficiency 90% Antistatic PVC curtains [optional] Motor blower assly: High capacity, FRP blower with aluminum impeller dia 7” * 4 ½” Specifications: Class 100 air PHEROH make HEPA filter eff. 99.997% down to 0.3 micron (As a supply filter) Electrical supply 3 phase, 440 volt, 50Hz Velocity 90 +/-20% below working area Operation: Equipment is used for dispensing of powder and chemicals to minimize risk of contaminating of work area & ensures health for working person under laminar air flow Equipment is based on 3 levels of filtrations of air circulation that ensures cloud or particles formed by material dispensed are sucked down. Magnehelic gauge indicates pressure difference between the filters During the initial cycle it achieves class 100 air with velocity 90 +/-20% below working area
