How to Troubleshoot Clogged Filters

By 2019-10-23 00:00:00 1 comment

If the filter on your Oneida Air Systems dust collector clogs quickly (e.g. it collects as much dust and debris as you find in the drum), it’s likely there’s an air leak somewhere below the cyclone.

How our dust collectors work

Oneida Air Systems' cyclonic dust collectors pre-separate over 99% of dust from the air stream before it has a chance to clog your system’s filter.

To work properly, these systems need the dust collection drum to be under negative pressure (in other words, in a vacuum). The centrifugal force of the cyclonic action pushes dust particles to the outer edges of the cyclone where they spiral down toward the collection drum. The clean air from the center of the spiral is pulled back up and sent through the filter.

Cyclonic action separates dust from the air stream, pulling clean air up through the filter.

What happens with an air leak

When the cyclonic system isn’t perfectly sealed, outside air is able to leak into the system. That air disrupts the cyclonic flow and creates turbulence. Dust particles end up in the center of the cyclone, where they get pulled up and sent to the filter.

It doesn’t take long for the filter to become clogged and for the system to become ineffective.

Turbulence allows dust into the stream of clean air being sent to the filter.

How to find an air leak

Check all connection points between the housing and the cyclone, as well as the bottom of the cyclone and the drum. We recommend using the smoke from burning incense to see where air is moving around your system. Simply light an incense stick while the system is running and move the stick:

  • Around the perimeter of the cyclone where it connects to hose, ductwork, or directly to the drum lid
  • Around the perimeter of where the drum lid meets the drum
  • Damaged spots on fiberboard drums
  • Any other connection points in your setup

If you see the incense smoke being drawn into the system, you’ve found an air leak that needs to be sealed. Keep looking for other leaks, including damaged spots on fiberboard drums, until you’ve exhausted all possibilities.

Air leaks can be found wherever the smoke from burning incense is drawn into the system.

How to fix an air leak

Depending on your system and the location of the air leak, you may need to:

  • Tighten or reposition hose clamps
  • Replace a neoprene gasket
  • Add tape to rigid ductwork
  • Apply silicone caulk

If you have questions about how to fix an air leak in your Oneida Air Systems dust collection system, please contact our Customer Service Team at (866) 387-8822.

Solutions to fix air leaks depend on the location of the leak.

Thanks for helping us keep our systems performing as designed. More info like this is what woodworkers need.
