FRED Sr. II Dual-Arm

A professional welding smoke extractor, the FRED Sr. II Dual-Arm Portable Fume Extractor is the industry standard for eliminating smoke, dust, and fumes from the air. A 2500 CFM, 5HP blower ensures a high face-velocity across two independently movable capture arms. Equipped with our standard MERV 15 rated Nanofiber filter, FRED Sr. II can remove particulate matter as small as 0.5 micron from the surrounding air of welding stations and other industrial operations.

Our patented Injection Self-Cleaning System (ICS-360) extends filter life expectancy while improving aggregate filter efficiency. Routine service is made faster and easier compared to manual cleaning systems, reducing total cost of ownership for our portable fume extractors.

Before you use your unit, you’ll want to perform a function test to verify it’s in working order.

Confirm correct Voltage and Amperes
Close front and back doors.
Turn the power switch to “On”.
Look to confirm that the unit is level and stable. Verify nothing is obstructing extraction path.
Listen closely to the motor and suction sound of the unit. Are they within the expected noise limits?
Place hand on top of the unit and feel for any unexpected vibration. Place your hand in front of the intake surface to confirm the expected levels of suction.

+ Perform Routine Maintenance

Weekly Inspection- Empty Dust Drawer

Remove dust drawer and deposit accumulated particulate in appropriate waste container. (Dispose according to local regulations.)

Filter Replacement

As required.

Yearly Inspection

Clean labels and exterior surfaces.
Capture Arm: Check for tears in flex hoses and fitting of hose clamps.

ICS-360 Function Test:
- Open Cabinet Door (keep open).
- Remove Filter.
- Turn unit ON then OFF.
- Observe if ICS-360 cycle initiates (normal delay of 30 seconds).

Troubleshooting

+ Your FRED Sr. II Dual-Arm unit does not turn on

Confirm correct voltage. Make sure the remote switch has been plugged into the correct voltage.
Check fuses. Make sure the fuses are intact and there hasn’t been a loss of power phase.
Check motor rotation. Confirm the correct rotation using the indication arrow located on the motor. If the unit fails to turn on, the unit’s motor could be in reverse rotation and spinning incorrectly. An electrician is required to address the problem.
If the problem continues, contact Diversitech support for assistance.

+ The cleaning mechanism is not functioning

Confirm correct voltage. Make sure the transformer (Primary and Secondary) has been plugged into the correct voltage.
Check the nozzle tip. The nozzle tip should contain 2 magnets. For the cleaning mechanism to function properly, the magnets need to be maintained in place at all times.
If the problem continues, contact Diversitech support for assistance.

+ Dust is escaping through the exhaust stack

Check the filter latch. Readjust the filter latch as needed to keep the filter sealed into place.
Verify the condition of the filter gasket. Check the filter gasket for bypass, damage tears or rips.
Check the inside of the cleaning mechanism. If the mechanism is dirty on the inside, maintenance is required.
If the problem continues, contact Diversitech support for assistance.
