FUME CUPBOARD
TPE’s Perchloric Fume Cupboard and Scrubber uses a constant air volume (CAV) Labrocare® model fume cupboard combined with a wet scrubber mounted immediately above it to remove acidic particulates from the exhausting airstream.
TPE’s Perchloric Fume Cupboard and Scrubber uses a constant air volume (CAV) Labrocare® model fume cupboard combined with a wet scrubber mounted immediately above it to remove acidic particulates from the exhausting airstream.
Cleaning is accomplished as the contaminated air passes through the scrubber chamber which is filled with wet, high-surface-area, polypropylene packing material called Pall Rings. When the airstream encounters the sprayedin water flowing across the Pall rings, acidic particles are absorbed into the water. The water and the particulates drain down across the back of the fume cupboard baffles and into a sump beneath the work surface. From the sump, the spent water is either drained away as waste or recirculated by an optional recirculation system
When the fume cupboard is turned ON by touching the Fan button, a solenoid automatically initiates the water spray heads, which continuously wet the pal rings. After passing through the Pall Ring bed, the exhaust airstream passes through a mist eliminator pad which removes the remaining moisture from the airflow, so the air exhausted up through the fan and out the stack is essentially moisture-free.
Non-Recirculating Scrubber. Scrubber water runs down internal baffles and drains through sump waste outlet.
