Cartridge Dust Collector
7.12 ON-SITE COMPRESSED AIR SUPPLY
Shut off the disconnect panel and lock out all electrical
power to the dust collector before performing any
service work.
Loosen check valve (white plastic part) connected to
brass tee threaded into air manifold reservoir to
completely relieve air pressure prior to performing any
service work on the air pulse cleaning system (refer to
Figure 8).
NOTE: 93-100 PSIG (6.4-6.9 BAR) compressed air is
required at air manifold reservoir.
As an option, the Supra-Conic
®
dust collector can be
configured to operate with an existing plant
compressed air supply. Clean, dry, oil-free 93-100
PSIG (6.4-6.9 BAR) compressed air is required for the
air pulse cleaning system to properly function.
Compressed air consumption is approximately 0.2
cubic feet (5.7 liter) for single diaphragm valve units
and 0.4 cubic feet (11.3 liter) for dual diaphragm valve
units. Refer to Specification Table for dust collector
valve quantities.
For the electrical control system to operate properly
with optional on-site compressed air supply, the
pressure switch contact lead wires must be
disconnected from the printed circuitboard controller
card across terminals labeled “SW PRESS.” Refer to
Figure 7 for printed circuitboard controller card
terminal block locations. The pressure switch with
unloader valve, air compressor, brass tee fitting and
check valve are not required for the Supra-Conic
®
air
pulse cleaning system to operate when the unit is
configured without an air compressor supplied by UAS
(i.e customer to provide plant compressed air supply).
The plant air connection to the Supra-Conic
®
is
located on the back of the dust collector, on top of the
air manifold reservoir. The connection is a female 1/4"
NPT fitting. Remove plastic plug from the half
coupling on the air manifold reservoir prior to making
final compressed air pipe connection. It is
recommended a shutoff valve be installed inline
between the air manifold reservoir half coupling and
plant air piping.
A shutoff valve, pressure regulator and pressure
gauge should be installed close to the Supra-Conic
®
dust collector. UAS recommends dedicated oil and
water removal filters be used to ensure clean, dry, oil-
free compressed air is supplied to the filter cleaning
system. Contact the nearest UAS office for
information about ordering a pneumatic valve kit.
Refer to Figure 18 for recommended compressed air
piping with a pneumatic valve kit.
