HafcoVac explosion proof industrial vacuums are suitable for use in Class I, Class II, and Class III environments, Division 1 and 2.  Our explosion proof pneumatic vacuums:

• contain no moving parts, eliminating possibility of ignition from mechanical friction or contact.
• use no electricity, eliminating sparks from motor arcing, shorts, switches, etc.
• are fully grounded when an explosion proof vacuum unit configuration is ordered, ensuring dangerous static electricity will not accumulate.

Intrinsic Safety is a protection technique for equipment operating in explosive environments. The principal states that electrical and thermal energy must not build up sufficiently to discharge.  With heat or friction risks such as those present when using an electrically operated industrial vacuum safely eliminated, static electricity remains.

The complete grounding of all components, including air supply line, vacuum generating head, collection drum, dolly and vacuum hose ensure that static electricity is continuously dissipated, protecting against dangerous static buildup, which could lead to electrostatic discharge (ESD), posing potentially serious consequences when in the presence of combustible substances. HafcoVac explosion proof vacuum models factory equipped as an explosion proof configuration ensures static electricity will not accumulate.

It is critically important that the operator understand the functions of the grounding system. Inspections are suggested prior to each use to ensure the integrity of all grounding wires and points. Care must be taken to not circumvent any grounding safeguards, and should also be exercised to ensure parts such as hoses aren’t used interchangeably with those from non explosion proof systems.
