1.0 Product Introduction 

The dust collector is used for the collection of 
airborne dust and particulate. Whether in 
answer to the problem of air pollution, or as 
part of a manufacturing process, the dust 
collector provides highly efficient and 
continuous on-line dust collection. 

The filter elements are the heart of the dust 
collector. These filter elements help ensure 
the only cleaned air is returned to the plant 
environment. 

During operation, contaminated air enters the 
dust collector through the dirty air inlet area 
and passes through the filter elements. Dust 
is collected on the surface of the filter 
elements. The filtered air flows through the 
centre of the filter elements into the clean air 
chamber, where it exhausts through the 
clean air outlet re-circulated into the 
environment. 

To ensure the optimal performance of your 
dust collector it is necessary that the filter 
elements are cleaned automatically 
sequentially. During the filter sequence, the 
timer energizes a solenoid valve, causing the 
corresponding diaphragm valve to send a 
pulse of compressed air through the filter 
elements (from the inside outwards), 
removing the collected dust from the outside 
surface of the filter elements. The dust falls 
through the hopper into the dust disposal 
system. 

2.0 Installation 

Ensure all persons carrying out work on the 
supplied equipment follow any relevant 
recognized standards or codes and are 
competent to do so. 

 

2.1

 

Compressed Air Connection

 

Compressed air pressure must be at 6 bar. 

Be sure that all compressed air components 
are adequately sized to meet the maximum 
system requirements of 45 Nliters per pulse 
at 6 bar supply pressure (= design pressure). 

Compressed air supply has to be both oil and 
moisture free. 

Connect the compressed air supply line to 
the compressed air connection of the dust 
collector. 

A compressed air shut-off valve, a filter/water 
separator with automatic condense drain, a 
pressure regulator with gage must be 
installed on the compressed air supply line. 

 

2.2 Electrical Connection

 

Enter the cable through the cable gland 
locate at the lower right corner of the 
collector. And enter the cable to the control 
box through the cable gland locate at the 
bottom of the enclosure. Please follow the 
electrical diagram provided for connection.   

Do not install in classified hazardous 
atmospheres without an enclosure rated for 
the application.
