HafcoVac Rock Dust Blowers are an economical and safe method for the application of non combustible rock dust in coal mines.
Very economically priced, HafcoVac Rock Dusters operate using compressed air common in many mines and require no permits, certification, approval, logs, etc. HafcoVac’s Rock Dusters have no moving parts.
Dust application rate is variable, making a HafcoVac Rock Duster a perfect solution for both trickle and bulk dusting operations. Custom configurations are available, though most mining customers choose either a 55 gallon drum model (~550 lbs of Rock Dust capacity) or a Hand-held model for insertion into a bulk supply bag.
Hundreds are now in use throughout WV/PA/VA
