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 70 requirements for grounding and bonding. These vacuums also meet 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.
The VAC-U-MAX 40008, 40012, and 40013 air vacs are a “system” and they include the vacuum cover, drum, dolly, vacuum hose and cleaning tools, compressed air hose with quick-disconnect fittings, and polybag drum liners. There are no components that are supplied by the customer and we are therefore able to offer a suitable-for-service certification in a Class II, Division 2 environment.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. |
