Donaldson Company, Inc.
Standard Equipment
Standard Downflo Evolution collectors consist of
collector module, inlet box, hopper, and legs. The legs
and hopper are assembled first and the collector is
placed in position using a crane or forklift.
Field Assembly
2. Set the hopper on the ground or a flat surface
with the collector connection flange down. The
discharge opening on the hopper base should be
oriented up.
3. Use drift pins to align holes.
4. Reference the Leg Positioning and Leg and Cross
Brace Assembly drawings. Attach the legs to the
hopper gussets using the hardware supplied.
5. Join multiple hoppers together at hopper gussets
using the hardware supplied. Do not tighten
hardware at this time.
6. Turn leg and hopper assembly over and position over
anchor bolts. Secure each leg pad to the foundation
anchor bolts with customer-supplied flat washers
and nuts. Do not tighten hardware at this time.
7. Level hopper.
8. Tighten all hardware securing legs, cross braces,
hopper gussets, and foundation anchor bolts.
Hopper Installation
There are four hopper styles offered for the Downflo
Evolution. A single module hopper spanning a single
collector module with two or three filter columns. A
double module hopper spanning a pair of collector
modules with two filter columns thereby accommodating
four filter columns. A taller, steeper, single module
hopper spanning one collector module with two filter
columns. A single module screw conveyor hopper
spanning one collector module with two filter columns.
All four hopper styles except the screw conveyor hopper
provide a 10-inch square discharge opening. The screw
conveyor hopper provides a single 18-inch discharge
opening.
Use proper equipment and adopt
all safety precautions needed for
servicing equipment.
Electrical service or maintenance work must
be performed by a qualified electrician and
comply with all applicable national and local
codes.
Turn power off and lock out all power before
performing service or maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
Turn compressed air supply OFF, bleed and
lock out lines before performing service or
maintenance work.
Field assembly of collector may be required due to
truck capacity, crane capacity, or specific customer
requirements. A detailed instruction drawing, shipped
with each collector will provide specific assembly and
lifting instructions.
Tighten all hardware before
removing crane to prevent
personal injury and/or property damage.
Leg Installation
Leg sets for standard collector sizes are shown in the
Rating and Specification Information. Reference Typical
Foundation Anchor and leg assembly drawing shipped
with the collector prior to starting assembly.
1. Prepare the foundation or support framing in the
selected location. Locate and install anchors.
Anchors must comply with local
code requirements and must be
capable of supporting dead, live, wind, seismic,
and other applicable loads.
Anchor sizes shown are provisional, as final
anchor sizing will depend on jobsite load
conditions, collector location, foundation/
framing design variables and local codes.
Consult a qualified engineer for final selection
of suitable anchors.
