Engineered Vacuum Cleaning & Loading Systems

Does your industrial processing plant require engineered vacuum cleaning and loading systems? With today’s emphasis on combustible dust control, most facilities do. FH Mason services southeast Michigan, northwest Ohio, and parts of Indiana. We offer systems from Hoffman®, Lamson®, Invincible® and Multi-Vac.

How do I know which Vacuum Cleaning & Loading System is best for my application?

Vacuum loading involves moving larger quantities of material – piles, rather than everyday dust and dirt that is on floors and machinery. The type of vacuum producer is different and the ratio of material to air is much higher. Vacuum cleaning may move hundreds of pounds per hour while vacuum loaders move tons of material per hour.
