The system is suitable for production facilities where ducting cannot be installed, where very large fabrications are being welded, or where capture at-source is not practical.
Contaminated air is first drawn into the unit at low level. It then passes through the filtration section containing 16 patented Uni-Clean filter cartridges, before clean air is blown back into the workshop via 60 adjustable nozzles in the upper outlet plenum. Furthermore, because the air is blown at a height of approximately 5 m, annoying drafts at low level are minimised.
Filter cartridges are cleaned automatically by a compressed air pulse jet system, activated by an integral electronic controller.
The unit has a maximum air flow of 10,000 m³/hr that delivers a throw length of 21 m.
