1. IMPORTANT NOTICE
this manual contains important safety information
and precautionary measures. it is impossible to
list all potential hazards associated with every
dust collection system in each application. Proper
use of the equipment should be discussed with
united air Specialists, inc. (uaS) or your local uaS
representative. operating personnel should be aware
of, and adhere to, the most stringent safety procedures.
EXPLOSION HAZARD
• Avoid mixing combustible materials such as aluminum,
paper, wood or other organic dusts with dusts
generated from grinding materials. a fire hazard could
develop from sparks entering the dust collector. When
collecting flammable or explosive materials, the dust
collector should be located outdoors and incorporate
the appropriate safety measures and/or accessories.
• When collecting emissions from spark-producing
processes, care must be taken to reduce any potential
fire hazards. System design should
include methods to prevent sparks from entering
the dust collector. Dust collectors do not contain
fire extinguishing equipment unless specifically
ordered. experts in the field of fire extinguishing
equipment should be consulted for recommendations
concerning proper fire detection and suppression
systems.
• Some dust collection systems require explosion
venting. consult your insurance underwriter,
nfPa (national fire Protection association) manual
and your local fire authorities to determine the
requirements for explosion venting.
• Be careful and conscientious – consult national
and local fire codes, waste disposal, safety and
other appropriate authorities. comply with their
recommendations for the proper installation and
operation of dust collection equipment.
• Your dust collector was selected for a particular
application. consult uaS prior to making any
application or system changes.
• All explosion vent installations should be located to
allow full-unrestricted discharge when system pressure
exceeds the set pressure of the explosion vent. an
explosion vent should never be located where the
discharge from the vent will impact people or plant
equipment.
• Do not use the explosion vent as temporary work
surface for hand tools; i.e., wrenches, screw drivers,
etc. Such actions can cause premature failure to occur
via over stressing the explosion vent.
• All dust collectors handling hazardous or fire/
explosion risk dust, as determined by the user, are
recommended to be located outside the building in
non-traffic areas even though the dust collector is
equipped with an explosion vent.

2.2 DESCRIPTION AND OPERATION
the Sfc is a high-efficiency cartridge dust collector
designed to eliminate airborne dust as it is generated.
contaminants are captured at the source(s), then
conveyed through ducting to the cartridge filter section
(dirty air section) where the dust is collected. clean air
is then discharged from the unit through the clean air
discharge.
the dust collector is designed for on-line or downtime
cartridge filter cleaning by means of a customer-supplied
compressed air system.
the Sfc is a high-efficiency, horizontally-oriented
cartridge dust collector equipped with 9.48” i.D. and
13.87” o.D. cartridge filters. the larger diameter
Protura
®
nanofiber cartridge filter design allows for
lower pressure losses through the dust collector while
increasing the amount of media contained in each
filter. Sfc Series dust collectors have pre-engineered
backward-inclined or radial-type optional blower
packages in 2, 3, 5, 7-1/2, 10, 15, 20, 25 and 30 hp (1.5,
2.2, 3.7, 5.5, 7.5, 11, 15, 18.8, 22.6 kW) assemblies.
there are two primary modes of operation — the air
filtering operation and filter cleaning cycle. Both modes
of operation are shown in figure 1.
