1.3 Sizes
The OptiFlo pulse-jet cartridge collector is available in these basic
configurations: 2RC, 3RC, 4RC, and 5RC series. All modules are two
filter elements wide. Sizes 2RC4 and 3RC6 are one filter deep—all
other sizes are two filters deep.
The 2RC modules have filters arranged two-high, 3RC modules have
filters arranged three-high, 4RC modules are four filters high, and
5RC modules are five filters high. Each series offers standard factory
assembled collectors with model designations such as: 2RC8;
2RC16; 2RC24; 2RC32; 3RC12; 3RC24; 3RC36; 3RC48; 4RC16;
4RC32; 4RC48; 4RC64; 5RC20; 5RC40; and 5RC60. The second
number in the model designation indicates the total number of
cartridges per collector.
1.4 Factory Assembly
All OptiFlo dust collectors are shipped in sub-assemblies
requiring only:
• Field bolting of the hoppers, legs, and braces
• Connection of ductwork and/or the fan
• Mounting and wiring of the control box
• Connection of compressed air supply
• Differential and air pressure gauge connections
The collectors are shipped with filter elements installed. Units shipped
as 4 or greater assembled modules are not skidded. Instructions for
field assembly are given in subsequent sections.
The main housing is constructed of 7 gauge carbon steel. Each
module is complete with pulse-jet piping, 1-inch diaphragm pulse
valves, pilot solenoid valve control boxes, and 6-inch diameter
externally mounted compressed air reservoir. The compressed air
reservoir is provided with (2) 1
1
⁄ 2 inch NPT pipe couplings for
compressed air attachment and drain.
2.0 Installation Instructions
2.1 Inspection
The OptiFlo dust collector is normally shipped by truck and should be
checked for any damage that may have occurred en route. Any
damage should be noted and the carrier notified within 24 hours.
2.2 Installation
(See Figure 2 for Typical Installation, and Figures 6 and 7, back page
for parts.)
A crane is recommended for unloading, assembly and
installation of the OptiFlo dust collector. Stand hopper(s) on their
discharge side (hopper outlet) and apply caulk to hopper flanges in a
figure-eight pattern around bolt holes. Lift cabinet from the truck,
position over hopper(s) and bolt cabinet and hopper(s) together with
3
⁄ 8 " x 1
1
⁄ 4 " thread cutting bolts, flatwashers, lock-washers, and nuts
as shown on Bolting Detail - Hopper to Cabinet, back page.
1.2 Normal Operation
During normal operation (See Figure 1), air enters the OptiFlo dust
collector through the inlet and passes through the filter elements. Dust
is collected on the outside surfaces of the elements and clean air
flows through the center of the elements into the clean air plenum, in
true “downflow” fashion, where it exits through the clean air outlet.
During filter element cleaning, a solid-state control timer automatically
selects the element or pair of elements to be cleaned, activating
solenoid valves which open air diaphragm valves. High pressure air
pulses directly into the center of the selected element, or pair of
elements, for 100 milliseconds, blowing collected dust off the filter
element(s). The dust is swept downward into the hopper by the
prevailing airflow and by gravity.
NOTE: For multiple module units, an inlet in each module is
mandatory to optimize performance.
