Introduction
Thank you for choosing the RoboVent HVE Hi-Vac filtration machine. This high-
vacuum unit is designed for industrial environments, collecting both fumes
and dust at the source in welding and related processes. The energy-eicient
motor is directly coupled to the regenerative blower and operated by onboard
controls, combining what might otherwise be a very complex operation into a
simple, user-friendly package. It ships in two pieces, the motor/filter cabinet
and the dust containment (hopper) and is pre-tested, making it easy to set up
and use.
The HVE Hi-Vac machine has been designed for production use and has a few
standout characteristics:
Regenerative blower: The backbone of the machine, it requires little
maintenance, and the advanced design provides the powerful suction required.
Vertical cartridge filters: Vertical cartridge filters have superior loading and
cleaning performance; RoboVent Endurex filters improve on these inherent
characteristics with proprietary design features that optimize performance and
promote eective pulse cleaning.
Pulsing system: Automatic and eicient, the pulse system ensures filter life is
maximized. Online and oline modes work together as needed to ensure filter
is consistently cleaned: a quick pulse sheds dust from the filter, causing it to
fall into the hopper area and collect in the drum. Eective pulsing is combined
with a filter chamber designed to prevent re-entrainment of dust, resulting in
maximum filter life.
Intuitive controls: Simple, intuitive controls are equipped with auto and
manual blower modes. Optional sensors integrate filtration with welding
processes. Additional electronics monitor airflow and motor speeds to indicate
operating condition with green, yellow and red lights.
With user-friendly electronics and only requiring connections to electricity and
compressed air, the HVE Hi-Vac machine is simple to set up. Additional details
can be found in the section titled “Prerequisites for Use”.
Persons involved with installing, operating, maintaining, and servicing this
RoboVent HVE Hi-Vac machine must read these instructions prior to use. Keep
this manual in a safe and convenient place for reference. In the case of loss or
damage, please contact RoboVent for replacement.

to file shortage reports and damage claims with the carrier. The carrier is
responsible for any damage to the equipment while it is in transit. Notify
RoboVent if any damage has occurred so repair can be arranged.
The filter cartridge(s) will be shipped inside the machine.
Before discarding packing material, make sure no small parts are concealed
within wrapping.

PURPOSE & LIMITATIONS
The HVE Hi-Vac filtration machine is designed for use with fume extraction
welding guns in production applications. Its powerful suction, simple
controls, and small footprint are suited for use in many facilities, including
fabrication shops, production facilities, shipbuilding, and large structures.
This machine is intended for filtration of airborne fumes and non-explosive
dry dust captured at the source. The design and controls are optimized for
welding processes, especially when used with fume extraction welding guns,
but it can be used intermittently for related processes such as grinding or
sanding.
