Cartridge Dust Collector
1. IMPORTANT NOTICE
This manual contains specific information concerning
safety and precautionary measures. It is impossible to
list every potential hazard associated with dust
collection equipment or systems. Use of the equipment
must be discussed with a factory-trained, United Air
Specialists, Inc. (UAS) representative. As always,
please adhere to the most stringent safety procedures.
2. INTRODUCTION
Thank you for selecting United Air Specialists dust
collection equipment to assist you in your commitment
to a clean and safe environment.
2.1 UNIT NOMENCLATURE
Collection Method:
B = Downdraft Bench
F = Fixed Ducted Unit
P = Portable Unit w/ Swing Arm
Nominal Flow Rate:
750 = 750 CFM
1500 = 1500 CFM
Example:
VB-1500
This would be a downdraft bench with a nominal airflow
of 1500 CFM.
2.2 DESCRIPTION AND OPERATION
The V Series Dust Collection System is a high-
efficiency, cartridge dust collector designed to eliminate
airborne particles as they are generated. Contaminant
is captured at its source by a unit-mounted hood,
downdraft table or ducted inlet and then conveyed
through the cartridge filter section where it is collected.
Clean air is then recirculated back to the work area.
There are two primary cycles of normal operation for
the V Series — the air filtering operation and the filter
cleaning cycle utilizing a compressed air cleaning
system.
Figure 1 shows the basic system operation and
equipment of a V Series dust collector.
2.3 AIR FILTERING OPERATION
The contaminated air stream is drawn into the collector.
Once the dust-laden air enters the cabinet, it meets a
baffle plate that disperses the air and significantly
reduces the air stream velocity. This provides even
distribution of the air stream across the entire surface
area of the cartridge filters, allowing a uniform dust
cake to form. The reduced air stream velocity causes
the heavier particles to fall out and collect in the dust
drawer.
The air stream then passes through the cartridge filter
where it is stripped of the particles by the media.
Cleaned air flows through the center of the filter,
through the blower (and optional safety after filters and
exits through the rear of the cabinet, back into the
workplace.
2.4 FILTER CLEANING CYCLE
As the cartridge filter becomes loaded with
contaminants, it becomes necessary to clean the filter
to maintain adequate airflow.
The compressed air cleaning mechanism provides brief
bursts of compressed air into the cylindrical cartridge
filter. When actuated, the cleaning system directs 90-
100 PSI of customer supplied compressed air through a
pulse valve, into a blow pipe, creating a burst of
pressure through the inside of the cartridge filter. This
pressure dislodges the dust and reduces the pressure
drop across the filter so the system can maintain
adequate airflow.
3. SPECIFICATIONS
Air Collection Method:
The V Series dust collector comes in three basic dust
collection configurations.
1. Downdraft Bench Unit (VB)
2. Fixed Ducted Unit (VF)
3. Portable Unit w/ Swing Arm (VP)
Within these variations, the units have two different
models, the 750 and the 1500.
Cleaning Options:
There are two basic filter-cleaning options with the
V Series: a cleaning system utilizing compressed air
and an option where the filters are cleaned manually,
external to the dust collector cabinet by the customer.
Power Supply Options:
All 1-1/2 HP motors are available in 115-230/1/60 and
200,230,460,575/3/60. All 3 HP Motors are available in
200,230,460,575/3/60.
