Pressure Drops in a Dust Collector

In a Dust Collector Differential pressure can be defined as the pressure difference between the dirty side of the filter chamber and its clean side, that is, it is the resistance that is generated when the air flow enters the filter chamber. in the collector.

The data obtained during the monitoring of the differential pressure can give us an idea of the condition of the filters and determine if they still retain their filtration efficiency or if it is necessary to change them; in addition to identifying possible causes when failures occur. To give us an idea of how to identify a pressure drop, you can review the following:

1. If the pressure drop is less than expected, then…

  • One of the causes could be a fault in the design or manufacture of the collector.
  • Error when calculating the air flow and it turns out to be less than expected.
  • Union seal failure.
  • Ducts with holes or poorly manufactured.
  • Accumulation of residues in the ductwork, which causes an unforeseen resistance.
  • Damaged or poorly placed filters.
  • The fan does not have the necessary capacity to move the air in the ducts.
  • The fan is turning in the opposite direction to that indicated.

2. If the initial pressure drop is higher, then you can consider the following…

  • It can also be caused by poor sizing or manufacturing.
  • high filtration speed
  • Accumulated dust.

3. If the differential pressure drop across the filters is stable for a long period and suddenly drops suddenly, then check…

  • Fan failure
  • There may be some kind of blockage in the system.
  • The filters could be damaged (Possibly Broken)
  • Air leaks could be the cause, check ductwork and manifold body closely to confirm a complete seal.

4.     If the pressure across the filter media stays stable for a long time, but suddenly increases, you can check this...

  • Fan failure
  • There may be some kind of blockage in the system.
  • The filters could be damaged (Possibly Broken)
  • Air leaks could be the cause, check ductwork and manifold body closely to confirm a complete seal.

Constant monitoring of the pressure differential, physically or digitally, will allow you to ensure that the pressure is or remains within the operating range.

Another way to verify the state of the differential pressure in the collector is if a system is installed to monitor the filters, this will allow early warning of possible variations or prevent critical points from being reached.

In addition, this allows you to anticipate possible failures and schedule preventive maintenance when necessary.

Remember that, if the air flow through the system has already reached the limit established by the collector's operating threshold, this normally indicates that the filters must be changed, they must be replaced completely, not in parts, since with this you guarantee the correct functioning of the filter media.

DYNA FLO® Tips: 

  • If you need to improve the performance of your dust collector, call us and we will gladly solve it.
  • Remember that a dust collection system needs to be serviced at least once a year.
  • When changing filters, they must all be replaced, you should never change half or only some, since dirty filters can damage the new ones.

Filtration speed

It can be defined as the proportion of air that passes through the filter cloth, that is, the amount of air that passes through each square foot of the filter media area per minute.
