When selecting a compound vacuum, HEPA vacuum, or ULPA vacuum for your facility, you will quickly find there are many options. From basic vacuums with a collection container and motor to those that are much more sophisticated and complex, it’s easy to lose sight of what’s important.
Intermittent-Duty Vacuums vs. Continuous-Duty Vacuums
Determining whether you need an intermittent-duty vacuum or continuous-duty vacuum is the first step in narrowing your choices. Your final decision should depend on the requirements of your specific application and your electrical requirements. If your application requires constant collection, continuous-duty is the best option. Continuous three-phase power is also more economical; however, not every plant has three-phase power available. Single-phase power is more prevalent but can limit the power of the vacuum. Nonetheless, if the vacuum will be used for general cleanup of work areas for approximately an hour or less each day, an intermittent-duty, single-phase industrial vacuum is your best bet.
