HafcoVac rock dust blowers are an economical and safe method for the application of non combustible rock dust such as limestone or gypsum 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. as they are pneumatically operated. 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 dust operations. Custom configurations are available, though most mining customers choose either a 55 gallon (~550 lbs of limestone Rock Dust) or a model for insertion in a bulk supply bag.
