Industrial mechanised polishing operations create an emission challenge because of the presence of polishing mop fibres, liquid polish droplets and fine metallic particles. Ideally the extraction ductwork should be kept to a minimum length and employ a higher than normal conveying velocity to reduce the risk of deposition within the ducts. For this application AAF believes the ideal collector is the RotoClone N in arrangement C. The latest development of this product allows for electronically controlled variable scrubbing pressure which when coupled with an inverter controlled fan provides exceptional flexibility of operation. Minimal downtime and inherent safety are further benefits offered by AAF RotoClone systems.
