The 2 m Downdraft extraction booth is designed to control fumes created during liquid solvents dispensing and the 2 m Downflow extraction booth is designed to control dust during the weighing of glass powders. Both booths are fabricated from 304 stainless steel sheet and meet CoSHH legislation requirements.
The Downflow booth is a one-piece design with the fan enclosure being acoustically lined to reduce noise levels. The air is collected at low level and filtered through 3-stage primary, roughing and secondary bag filters and then finally though HEPA filters providing 99.95% filtration efficiency. The filtered air is discharged above the operator's head with an evenly distributed down flow of 0.5 m/second. This system provides a continuous down flow to suppress dust below the operator's breathing zone into the extraction area.
The extraction performance of the booth is monitored through pressure indicting devices and automatic control of the variable speed fans.
The Downdraft booth provides a laminar airflow with fumes being filtered through a F7 category primary filter and a carbon filter. Extraction is through a rear mounted 7.5 kW centrifugal fan discharging back into the room where this booth is located. The fan starter is located on the booth control panel removing the need for any special on-site wiring.
