X. Accessories
Bin Level Monitor - Provides level sensing for dry bulk solids. The monitor
operates by using a 1 rpm synchronous motor to rotate a paddle.
When paddle rotation is impeded by material surrounding it, the motor
is de-energized and triggers a SPDT snap switch. The snap switch can
be used in conjunction with a motor starter to turn equipment off or
provide alarm functions.
Magnetic Motor Starters - The 3hp high pressure dust collectors do not
come wired or with an on/off switch. Because of the voltage and
amperage requirements of the system, an industrial switch must be
used.
OAS offers Square “D” Full Voltage Non-Reversing across the Line
Starters, Nema Type 1 Enclosure with Start/Stop in cover, and class 10
overload. Industrial switches can also be purchased through your local
electrician. Due to varying electrical codes, OAS cannot specify exact
wiring requirements. When wiring the collector you should always hire
a licensed electrician.
The BAG Gripper
ABX000000
The BAG Gripper provides the ability to use convenient plastic bags inside
your dust drum. It provides a constant, negative pressure on the outside
surface of the plastic bag that keeps it pulled tight against the sides of the
dust drum. Can be used with 35 and 55 gal. barrels. Must be wired into
your system.
Dust Bin Options - (Must Order Custom Mounting Stand.)
1. Multiple Drums -
Custom order the System Mounting Stand for multiple drums or hoppers.
Stand widths will vary depending on dust container.
2. Hoppers -
Large capacity hoppers from .5 cu. yd. to 3 cu. yd.
3/16” reinforcing angle for added support - 3/16” plate body is 100% continuously
MIG welded on inside - 3/8” rear cross brace angle (not 3/16”) - three 3” base
channel - All angles are structural not formed.
3. Air Locks -
Rotary air locks provide an alternative to an air tight dust bin for larger
volume capacity and less maintenance.
Example - A 10” air lock will drop 1.85 cu. ft. / rev. of material.

XI. Troubleshooting
Motor Overheating
The motor’s internal circuit breaker will trip if the motor is overheating.
Motor amperage too high - Shut system down.
Caused By:
System should be completely bolted and sealed together.
Ductwork should be completely installed and sealed with sealant.
Air leaks between the collector and dust bin
- The lid of the dust bin and the cyclone must be in place and sealed when operating the dust collector.
- Make sure flex hose is not torn and the hose clamps are tight.
- Check drum lid; cover should have a foam seal and be well seated.
- Check for holes or leaks in the dust bin barrel.
Motor not properly wired. Check wire connections.
- Check motor rotation - See wire diagram
Check breaker box. Make sure incoming power supply matches motor specifications.
Poor Dust Pick-Up at Woodworking Machines
Caused By:
Improper motor rotation - Running backwards will reduce suction by 30%.
Check length of duct runs and duct diameters compared to ductwork design guideline.
Make sure all ductwork is sealed. Large air losses will occur even through small cracks in the
ductwork. Use silicone, duct tape or duct mastic compound as a sealant.
Check for air leaks between collector and dust bin.
Close all unused blast gates at your woodworking machines.
Examine hood design for weaknesses according to the ductwork guide.
Check for a restricted pipe, too small a hood port or too small a branch line. See branch line
diameter chart in ductwork guide.
Be sure that your filter is clean. See filter cleaning directions.
Filter Clogging
Caused By:
Air leakage between cyclone and dust bin. Cyclone and dust bin must be air tight. Even small leaks will cause
poor preseparation in the cyclone.
Large chips clogging the filter
- Check for a leak in the dust bin, flex coupling or lid. Check for split or torn flex coupling. (See
also: Motor Overheating Section above)
- Make sure dust bin has not over filled. Dust bin should be emptied before the dust reaches
top of the container.
- Interruption of air flow, such as vacuuming chips with a flex hose connection, will increase
filter maintenance.
- Minimum 4” diameter pick up at tool location. Less than 4” will restrict air flow into collector and
will increase filter maintenance. If there is not enough air entry in system, open more blast gates.
- Make sure clamp around cyclone is tight and sealed with silicone.
Excessive Vibration
Caused By:
Loose mounting bolts
Excessive system pressure or restriction of air flow due to closed blast gates.
Accumulation of foreign material on the fan wheel.
Inadequate support structure.

Read Before Installing and Operating
XII. Fire Hazards -
Oneida Collectors are designed for WOOD DUST only!!
Wood shaping and cutting processes generate wood chips, shavings, and dust. These materials are considered
combustible. Air borne wood dust below 420 microns in size (.017 of an inch) in certain concentration ranges when
ignited can deflagrate (burn quickly).
An ignition source such as a spark, or ember, can ignite a dust mixture resulting in an expanding flame front, which
can cause an explosion if tightly contained. A disturbance that raises a cloud of accumulated fine dust can raise additional
dust clouds, which can cause a series of explosions that can level an entire building. Until this type of fire has been
witnessed, it is difficult to believe the devastation. This type of fire is rare but worth safeguarding against.
The best way to avoid a wood shop fire is to keep the shop clean. A shop ankle deep in dust with layers of fine dust
everywhere is an accident waiting to happen. A good dust collection system reduces overall fire hazards but also adds
new concerns. A fire hazard is still present. Combustible material is now in the dust collector and storage container.
The following points are worth heeding:
It is the buyer’s responsibility to follow all applicable federal, state, local, OSHA, NFPA, or authorities having
jurisdiction codes and regulations when installing and operating this dust collector.
Fire Marshalls may want the unit located outside of the building. If the collector is located inside the facility,
controls such as spark detection, suppression, or explosion venting may be required.
Most local jurisdictions consult or adopt NFPA ( National Fire Protection Agency) codes. However, other codes
may apply. Local codes may vary from jurisdiction to jurisdiction.
NFPA 664 Code book, “Standard for the Prevention of Fires and Explosions in Wood Processing and Woodworking
Facilities”, applies to woodworking operations that occupy areas of more than 5,000 sq. ft. or to areas where
dust producing equipment requires an aggregate dust collection flow rate of more than 1500 cfm (Cubic Feet
per Minute). This exempts some small operators from the NFPA code 664, but other codes may apply in your
jurisdiction. Consult your local Fire Marshall for help. Additional information can be found in NFPA Code Book
664.
The customer assumes the responsibility for contacting their insurance underwriter with regard to specific
application requirements of explosion venting or if additional fire protection and safety equipment may be
required.
Do not use this product to collect other types of dust or flammable vapors.
Fire or explosion may occur!
Never collect sparks from a bench grinder into a wood dust collector.
Never introduce sparks or sources of ignition into the dust collector.
Personnel should keep at least 20 feet away from unit.
Check dust bin frequently and before leaving the shop for smoldering material.
Keep portable Fire Extinguishers handy.
The ABC type (dry chemical) is generally a good choice for small wood shops.
Additional information on portable extinguishers can be found in NFPA 10 (Standard for Portable Fire Extinguishers).
Be especially careful with sanding units. They can produce concentrations of dust in the combustible range. Make
certain enough air volume is at the suction point to capture all the particulate generated.
This high air volume will dilute the mixture below the lower limit of flammability. Be careful not to generate sparks into
the sanding dust.
Empty dust bin and clean filter often, especially when sanding.
Don’t overload woodworking equipment, especially sanders. Excessive frictional heat can spontaneously ignite dust.
Sparks can be generated in several ways:
High-speed sanders and abrasive planers may strike foreign material
Saws and edgers may strike foreign material and create a red hot metal fragment.
Knots in hardwood can create frictional sparks.
Tramp metal when drawn into the collector can spark against ductwork.
Check wood stock for old nails and screws which can create red hot metal fragments.
Avoid using excessively large wood waste storage bins.
Always check storage bins for smoldering material before leaving for the day.
Electrically ground all equipment and ducting. Static sparks can ignite wood dust. (Avoid using PVC drainpipe)
Don’t allow accumulation of layers of fine dust on horizontal surfaces. (Especially overhead lights, electrical boxes,
and fuse panels which can ignite dust)
