EXAIR’s patent pending EasySwitch vacuum simplifies the filter change process when switching from vacuuming a dry material to a liquid or vice versa. Utilizing minimal compressed air, the EasySwitch is a powerful pneumatic vacuum that is ideal for any application - wet, dry, light and heavy. The EasySwitch is designed to handle the toughest of industrial cleanup jobs with ease. It rests upon any 55 gallon drum. With EXAIR’s patent pending lid design, the EasySwitch vacuum uses a standard or HEPA certified filter when vacuuming dry material. The fast and simple conversion to vacuuming liquids is done by releasing one latch and simply removing the filter element. The EasySwitch vacuum creates a powerful vacuum (at a quiet 79 decibels) without the need for electricity. Because the vacuum generator has no moving parts and uses no electricity, there is little concern for failed parts, motor failure or working with liquids associated with electric industrial vacuums.
