SECTION 200
Glossary of Terms
Autogates/Blast Gates: Blast gates are gate valves used to focus a dust collection
system's vacuum pressure for maximum dust (or other material) extraction at the
desired location. Blast gates are positioned near individual pieces of machinery and
operate by being, by default, closed — blocking air flow. They are opened as needed
to achieve the desired air velocities at the specific inlet point.
Containment: This term is used to describe the portion of the dust collector that is
collecting particulate for removal and/or disposal. This is typically either a hopper, or
a tray.
Control Panel (RV-3.0): A RoboVent Control System that controls the Blower and Pulsing
functions through an easy to understand Interface. Control the pulse timing and
trigger points; Set Filter service alarms; setup Automatic Run schedules. Operate
and control the blower speed manually or automatically through the control screen.
Monitor Filter pressure and see operation events.
Damper: A damper is a valve or plate that stops or regulates the flow of air inside a duct,
chimney, VAV box, air handler, or other air-handling equipment. A damper may be
used to cut off central air conditioning (heating or cooling) to an unused room, or to
regulate it for room-by-room temperature and climate control.
Delta3: RoboVent’s proprietary Spark Arrestor that utilizes cylindrical force and air patterns
to extinguish sparks and prevent then from entering a dust collection system.
Differential Pressure: The difference in pressure between the dirty air side of the
enclosed plenum and the clean air side of the enclosed plenum. This difference
quantifies the amount of loading across the cartridge filters installed in the machine
and allows you to monitor and understand when a filter change is necessary.
Typically measured in either KPA (Kilopascal) or Inches of Water Column (Notated by
SP or WC).
Fire Suppression System: A system that is installed onto an industrial machine, e.g.
a dust collector, to control a fire from spreading. These systems allow necessary
personnel to get to the scene of the event and react appropriately, while using gas
or chemical agents in the space the event occurred to limit its immediate damage.
Hexavalent Chromium: Hexavalent chromium [Cr(VI)] is one of the valence states (+6)
of the element chromium. It is usually produced by an industrial process. Cr(VI) is
known to cause cancer. In addition, it targets the respiratory system, kidneys, liver,
skin and eyes. Chromium metal is added to alloy steel to increase hardenability and
corrosion resistance. A major source of worker exposure to Cr(VI) occurs during "hot

Glossary of Terms
work" such as welding on stainless steel and other alloy steels containing chromium
metal. Cr(VI) compounds may be used as pigments in dyes, paints, inks, and plastics.
It also may be used as an anticorrosive agent added to paints, primers, and other
surface coatings. The Cr(VI) compound chromic acid is used to electroplate chromium
onto metal parts to provide a decorative or protective coating.
HMI: A human-machine interface (HMI) is the user interface that connects an operator to
the controller for an industrial system. In the dust collection industry, these interfaces
are utilized to connect the operator with the PLC that is controlling the operation of
the equipment.
Hopper: A container for a bulk material such as grain, rock, or trash, typically one that
tapers downward and is able to discharge its contents at the bottom. In the dust
collection industry, a hopper is used to contain and funnel collected particulate into a
tray or barrel so it can be cleaned out and/or removed from the dust collector.
OSHA: The Occupational Safety and Health Administration, an agency of the US
government under the Department of Labor with the responsibility of ensuring safety
at work and a healthful work environment. OSHA's mission is to prevent work-related
injuries, illnesses and deaths.
Plenum: an enclosed chamber where a treated substance collects for distribution, as
heated or conditioned air through a ventilation system.
Pulse Cleaning System: In RoboVent’s FlexPro Dust Collectors, dust and fume enters
from the side or back of the unit and flows from outside to inside the cartridge filters.
The cartridge filters are cleaned by short bursts of compressed air injected through
a common manifold that supports individual solenoid valves. The compressed air
is accelerated by a special nozzle mounted above the filter cartridge. Since the
duration of the compressed-air burst is very short, it acts as a rapidly moving air
bubble, traveling through the entire length of the cartridge and causing the surfaces
to flex. This flexing of the cartridges breaks the dust cake, and the dislodged dust
falls into a storage tray or hopper below. Reverse pulse-jet dust collectors can be
operated continuously and cleaned without interruption of flow because the burst of
compressed air is very small compared with the total volume of dusty air through the
collector. The bursts of air are timed, and controlled by the pressure differential of the
filters, as well as by pre-programmed threshold settings within the collectors onboard
control system.

SafeSensor: An optional particulate monitoring device that is commonly referred to as
a smoke detector. This device, if equipped, alerts your dust collector in the event
of a thermal event or bypass. The device is triggered by smoke passing by the
photoelectric sensing eye.
VFD: A variable frequency drive setup with pressure transmitters to control the speed of
the motor on the dust collector. This device regulates the motor speed and increases
its speed to compensate for losses occurring within the dust collector, primarily filter
loading. This allows the dust collector to maintain a consistent airflow throughout the
life of the cartridge filters while also saving energy by eliminating the need to run a
collector at full speed with little to no filter resistance.

Features
1. High Performance Blower Design
Each RoboVent FlexPro Series Collector comes
with a high output airfoil blower and direct drive
motor. This highly efficient blower design and
direct drive system maximizes the airflow (CFM)
delivered by the motor power requirements.
(see Figure 1).
2. Front Load System
Cartridge filters are easily accessible through
an oversized front door. The cartridge filters are
mounted on a robust filter yoke, and they are
secured with a threaded handle. This makes it
easy to change and replace filters. (See Figure 2)
3. Pulse Filter Cleaning System
RoboVent filter cleaning systems utilizes powerful
compressed air pulses for unmatched filter
cleaning. The on-line and off-line cleaning cycles
are pre-programmed for optimal efficiency but
can be customized for changes in usage patterns.
(see Figure 3).
4. Pulse Cleaning Valves
The RoboVent FlexPro Series Collectors utilize
a special cleaning cone which optimizes the
cleaning pulse by ensuring that the developed
overpressure in the filter is even throughout the
filter element. (see Figure 3).
5. Sturdy 7 and 11 GA Reinforced
Collector Housing Construction
This heavy-duty construction secures a lifetime
of industrial use. Seams are welded and sealed
to assure there are no leaks or cracks that could
contaminate the facility air system.
6. Acoustic Motor Plenum (HVE-950-80-2 Only)
High-density sound materials and Bass Trap
Acoustics have been implemented as part of the
blower compartment. The acoustically designed
plenum greatly reduces motor and blower noise
levels and decreases ambient noise into the facility.

7. Control Panel
The Modular Control panel contains all the com-
ponents that operate the FlexPro. Everything
is contained within the enclosure allowing the
controls to be mounted in various location configu-
rations on or near the Machine. (see Figure 4).
8. ePad Control System:
ePad control system allows control of all aspects
of the collector's functions including the blower,
filter differential pressure and filter pulsing system.
Preset from the factory with settings to cover most
applications with optimal pulsing for efficient dust
removal. ePad Control System allows for the user
to adjust the pulsing schedule if needed due to
changes in production or increased usage and
Auto or Manual start of the blower. (see Figure 5)
9. Large Capacity Dust Tray/Optional Hopper
RoboVent FlexPro Series Collectors come standard
with a 20 gallon steel drum (see Figure 6). An
optional 55 gallon drum is available for heavy
dust production applications or extra capacity
to reduce frequency of dust clean outs. Both
are designed to capture and store particulate
pulsed off the filter cartridges and minimize
"re-entrainment." (Re-entrainment is the term used
for picking up dust that has already been removed
from the filter and re-depositing it on the filter.)
10. SafeSensor Particulate Monitoring Device
(option)
If equpped, the SafeSensor particulate monitoring
device detects a leak past your filters. If a leak
occurs, the system shuts the equipment down and
sets off an alarm. The SafeSensor also monitors
smoke, and in case of a thermal event, will
automatically shut down the motor and blower. It
will also change the andon light to red and sound
a high intensity audible alarm. (see Figure 7).

11. A15 PleatLock Filters
(Standard, alternate medias are available)
The A15 PleatLock filter media is RoboVent's high
quality cellulose/polyester blend that provides
superior filtration efficiency and long life in
welding applications. Every filter is fire retardant
and uses Nanofiber technology to achieve a
MERV 15 efficiency rating. A15 PleatLock filters are
highly-efficient for particulate down to 0.1 micron
in size. (Figures 8).
12. VFD: Variable Frequency Drive
The VFD system uses a sensor that constantly
monitors the airflow. Using a VFD, it automatically
adjusts the RPM of the motor to compensate for
filter loading. This reduces energy peaks, resulting
in 20%-30% energy savings, and extending filter
life. The VFD is key for a system that is quieter, can
operate at maximum operating efficiency and
saves you money. (see Figure 9).
13. AutoSaver Auto On/Off (option)
The AutoSaver feature (if equipped) allows your
RoboVent FlexPro Series air filtration system to
rest when not needed, saving energy dollars.
This also allows the unit to enter off-line pulsing
mode to reduce filter loading if filter pressure is
above threshold limits. The AutoSaver turns the
system on when cutting, welding, or process
operations start and turns it off after the operation
is complete. (see Figure 10).
