VAC-U-MAX recognizes the importance of handling combustible dust safely, and has been proactive in this regard for decades. VAC-U-MAX was founded in 1954 to address the need for an intrinsically safe vacuum cleaning system for the textile industry. VAC-U-MAX founder, Frank Pendleton identified this need to collect combustible textile dust and debris safely; and the result was the development of the world’s first compressed-air powered portable vacuum unit that does not use electricity.
The OSHA National Emphasis Program for Combustible Dusts, initially released in October 2007 and re-issued for emphasis and increased enforcement in March 2008, has generated many inquiries about suitability of VAC-U-MAX Industrial Vacuum Cleaning Systems for use in Class II, Division 2 environments. VAC-U-MAX compressed-air powered vacuums, Models 40008, 40012, and 40013, are the first-line offerings for Class II, Division 2 environments due to their bumper-to-bumper grounded and bonded design and their reasonable cost and availability. These vacuums meet the NFPA 77 requirements for grounding and bonding, meeting the definition of an “intrinsically-safe system”.
VAC-U-MAX air-powered vacuums do not use electricity and do not generate any heat from operation. VAC-U-MAX air-vac models 40008, 40012, and 40013 are a “system” that includes the vacuum cover, drum, and dolly. The specific static control components of this family of vacuums are:
- Metal vacuum cleaning tools and static-dissipative vacuum hose
- Stainless steel anti-sparking inlet
- Static-conductive dust filter
- Ground strap across gasket between air vac cover and drum
- Drum dolly with static-conductive casters
- Ground wire connection between air vac cover and drum dolly
- Static-conductive compressed air hose with metal quick-disconnect fittings
- Static-conductive polybags liners for collection of combustible dusts inside the drum.
If the compressed air piping network in the facility is grounded (as it should be), then the VAC-U-MAX vacuum will be grounded automatically, eliminating operator error due to failure to connect separate ground wires.
