Insufficient Suction or Exhaust
-
High Differential Pressure- See cartridge problems.
-
Fan Direction of Rotation- The incorrect fan rotation will not provide
sufficient static pressure or volume and could cause motor overload.
-
Leaks- Infiltration of air from leaking ductwork, access doors, explosion
vents, dust discharge devices, or housing will cause insufficient suction.
Seal any leaks.
-
Closed Air Passages- Clogged ducts or closed dampers or gates will shut
of f or reduce the airflow.
-
Undersized Ducts- Duct size should be per the design specification.
Undersized ducts produce high static pressure, restricting the airflow.
-
Improper Shaker Cycle- Check the electrical components of the automatic
shaker for correct operation. Adjust shake time if required (normally 15-
20 seconds). Check for mechanical restrictions, which could hinder the
performance of the shaker.
Cartridge Problems (Blinding, Poor Life, Failure, etc.)
-
Check actual operating temperature of system against design
temperature.
-
Check for high operating humidity, free moisture, etc. Check for low
relative humidity and static electricity.
-
Check for shrinkage or stretching.
