Caution!
Application of Dust Control Equipment
lCombustible materials such as buffing lint, paper, wood, aluminum or steel dust, weld fume, or
flammable solvents represent fire or explosion hazards. Use special care when selecting and oper-
ating all dust or fume collection equipment when combustible materials are present to protect
workers and property from damage due to fire and/or explosion. Consult and comply with
National and Local Codes relating to fire or explosion and all other appropriate codes when
determining the location and operation of dust or fume collection equipment.
lWhen combustible materials are present, consult with an installer of fire extinguishing systems
familiar with these types of fire hazards and local fire codes for recommendations and installation
of fire extinguishing and explosion protection systems. Donaldson dust collection equipment is
not equipped with fire extinguishing or explosion protection systems.
lDO NOT allow sparks, cigarettes or other burning objects to enter the hood or duct of any dust
or fume control equipment as these may initiate a fire or explosion.
lFor optimum collector performance, use only Donaldson replacement parts.

Introduction
The Remote Weld Bench is an optional accessory
for dust collection systems. Standard models are
the RWB-2000, which is a 2000 cfm unit for use
with 2000 cfm dust collectors, and the RWB-3000,
a 3000 cfm unit for use with 3000 cfm dust collec-
tors. Technical and field support are always avail-
able from your local Donaldson Representative
and distributors.
Important: OSHA may have requirements regard-
ing recirculating filtered air back into your facility.
Consult with the appropriate local authorities to
ensure compliance with all applicable codes.
Operational Explanation
Normal Operation
During normal operation, the contaminated or
fume-laden air enters the Remote Weld Bench
through the backdraft. The fume-laden, incoming
air goes through the collar pack, which is ducted
to the dust collector. See Figure 2, Operational
Schematic. The dust collector that the Remote
Weld Bench is ducted to should have a flame retar-
dant filter media which can reduce the risk of fire
hazard.

Installation
Inspection
The RWB-2000 and RWB-3000 are normally
shipped by common carrier and should be careful-
ly inspected for damages that may occur en route.
Any damage should be noted and the carrier noti-
fied immediately.
Ship Loose Items
Items shipped loose with the Remote Weld Bench
may include:
lRemote Weld Bench Installation and Operation
Manual, IOM 9421701.
Preinstallation
Note: See Specification Control Drawing for foot-
print dimensions, weights, and any other load
information.
The standard Remote Weld Bench is delivered
completely assembled. See the Specification
Control Drawing for footprint dimensions and
weights. The total weight of the unit should
include auxiliary equipment and other live loads.
Remove all crating, strapping, wrap and securing
hardware from both outside and/or inside the unit.
Check the parts received with the packing slips. If
parts are missing or damaged, notify the carrier
and your local Donaldson representative immedi-
ately.
The welding work surface is seven gauge hot rolled
steel. A waterborne, corrosion-resistant clear film
has been applied to the work surface. Remove this
film by washing the work surface with a detergent
cleaner and then drying with a cloth before weld-
ing.
Note: DO NOT weld without removing the corro-
sion-resistant film. Oily residue will be generated if
the film is not removed.

Assembly of Standard Equipment (See Figure 1)
Each Remote Weld Bench is shipped fully assem-
bled from the factory. The RWB-2000 weighs
approximately 600-lbs. The forklift must be able
to safely lift the unit. The Remote Weld Bench
standard collar pack is factory installed in the back
of the unit. The collar pack can be relocated to
either side of the hopper by switching it with either
the maintenance access panel or the 3/4” NPT
sprinkler coupling panel. See Figure 1, Typical
Remote Weld Bench Installation.
Sprinkler Coupling
A 3/4” NPT pipe coupling is located on the right-
hand side of the hopper. It is used to attach a
sprinkler head if necessary. Check your local codes
for sprinkler requirements. See Figure 1, Typical
Remote Weld Bench Installation.
Note: Donaldson equipment does not include fire
prevention equipment, all sprinkler heads must be
supplied by others.
CAUTION!
Use care in selecting the installation
location for dust collection equipment
and follow all appropriate national and
local fire codes.

Collar Pack
The RWB-2000 has three collar pack sizes; 8, 10,
and 12-inch ID. The RWB-3000 has two collar
pack sizes; 10 and 12-inch ID. Make sure to use
the proper duct system inlet to connect to the col-
lar pack.
Backdraft Panel
The Remote Weld Bench backdraft panel is remov-
able by turning the lift and turn latches and pulling
the panel forward. Use the handles to remove the
panel. This feature allows the customer to clean
the dirty section of the unit. The dirty air section
should be initially cleaned after every 8-12 hours
of operation. When welding on oily parts, cleaning
may be required daily to remove any oily buildup
to minimize risk of fire.

Swing Door
Each Remote Weld Bench has a right and left, lift-
off swing door. This feature accommodates long
and awkward workpieces. When working on small
pieces, the swing doors should be closed to capture
all contaminates.
Optional Industrial Light Fixture (See Figure 3)
When the optional light fixture is ordered, the light
switch and cord are factory installed. Fluorescent
bulb must be supplied by customer.
Work Surface Grounding
The welding work surface is grounded by eye bolts
(two for RWB-2000 and four for RWB-3000) that
are screwed into the welding work surface. Please
refer to your welding supply operation manual.

Service
Scheduled Maintenance (See Figure 4)
1. Remove the welding work surface by lifting at
the eyebolts. See Figure 4, Scheduled
Maintenance.
2.Remove the backdraft panel. See Backdraft
Panel Section.
3. Remove the maintenance access panel.
4. Use dry sweeper or brush to clean the back wall
and inside of hopper. Depending on the fume
or dust properties, a putty knife may be used.
Dispose of contaminants properly.

5. Reinstall welding work surface, maintenance
access panel, and backdraft panel.
6. Regular dust removal in the maintenance sched-
ule can reduce the risk of fire hazard.
7. The Remote Weld Bench should be cleaned
every 8 to 12 hours of operation.

Troubleshooting
Trouble Possible Cause Remedy
Insufficient airflow 1. Fan not working
a. Incorrect fan When adding the Remote Weld Bench to
an existing dust collection system, make
sure the duct system is capable of handling
the losses and the remote bench pressure
losses.
b. Incorrect damper setting Check dampers for correct positioning.
