2.2 

Individual Module Assembly 

 

2.2.1

  The modules require field erection of the 

structural legs and brace assembly, assembly of the 
hopper and body, plus accessories such as ladder, 
handrail, exhauster and ducting, and explosion vents.  

 
2.2.2

  Erect the collector modules as shown in the 

assembly drawings provided. Pay special attention to the 
orientation of the inlet and outlet duct openings, access 
doors, ladder, handrail, and exhauster location. The 
module with the pressure regulator on the pulse manifold 
is an end module; refer to the assembly drawing for its 
positioning. If the collector is part of a blast room or 
automated cabinet, use the general arrangement 
drawings for the placement of the components.  
 

2.3 Connecting 

Modules 

Together

 

 

2.3.1

  All fasteners to bolt modules together are 

accessible from the outside except for the bolts on the 
inside of the exhaust plenum (between the plenum and 
cartridge chamber). 
 

2.3.2

  Check the assembly drawings for the sealing 

material (mastic, weather-strip gasket, caulking, etc.), 
and make sure the correct sealing material is in place 
before bolting the modules together.  
 

2.3.3

 

Connect side panels to the end modules using 

the seal and fasteners shown on the assembly drawings. 
 

2.4 Anchors 
 

 

 

 

 

WARNING 

 

All anchors must be calculated and specified by 
a qualified engineer. Inadequate anchoring to 
the footing could result in hazardous shifting of 
the collector and ducting, which could result in 
death or serious injury.

 

 

2.4.1

  Recheck orientation of the dust collector, blast 

room and recovery equipment, or other equipment the 
collector is ventilating. When satisfied that all are 
correctly positioned, anchor modules to the floor with 
anchors specified by a qualified engineer. 

NOTE: If 

there is any doubt about the final positioning of the 
dust collector, do not remove the lifting equipment 
until the collector is fully assembled, connected to 
the mating equipment, and ready to be anchored.

 

 

2.4.2

 

After the collector is firmly anchored, remove the 

lifting rigging.  
 

2.5 Exhauster 

Assembly

 

 

NOTE: The exhauster is usually floor mounted, and 
requires ducting from the collector, and an exhaust stack 
with a damper adjustable from 0-80% closed. Some small, 
single module collectors may have the exhauster mounted 
on the collector body, and do not require additional 
ducting. 
 

2.5.1

  Anchor the exhauster into position. NOTE: 

Positioning of the exhauster must coincide with the 
placement of the outlet ducting. Use a temporary anchor 
until the ducting is in place. 
 

2.5.2

  Attach exhaust stack and damper assembly to 

the exhauster outlet. 
 

2.6 Ducting

 

 

2.6.1

 

Clemco Industries Corp. does not usually supply 

inlet or exhaust ducting, but does provide a general 
arrangement drawing for suggested ducting. The top or 
bottom exhaust ducting plate, and inlet ducting plate 
may serve as a mounting flange, by cutting an opening 
and welding the ducting to the plate.  
 

2.6.2

 

All ductwork must be designed and installed by 

qualified licensed contractors familiar with industrial 
ventilation practices, and must conform to applicable 
codes. Where state or local codes conflict with one 
another or with specifications by Clemco Industries 
Corp., the more stringent regulation shall be followed. 

 

NOTICE

 

All ducts, joints, and connections must be tight. 
Any leaks will affect the overall performance of 
the system.

  

 

 

NOTICE

 

Ducting must be supported sufficiently to place 
no load on connecting equipment. 

 

 
 

2.6.3 

Exhaust Ducting. Figure 2

 

 

NOTICE

 

The joint between the duct and exhauster 
housing must be flexible, such as canvas or 
rubber with band clamps. The ducting must be 
self-supporting. NO LOAD IS TO BE APPLIED 
TO THE EXHAUSTER BY THE DUCTING.
