With winter coming make sure your bag house is working properly. KVA Engineering can inspect your filter for any shortcomings. We also can do leak testing to ensure the filter is returning clean air back into your work place to meet OSHA requirements.

Installation Tips

Be sure to check inlet collar ID and OD. When installing a dust collection system, people become frustrated when they are unable to slip pipe over or insert a coupling into the dust collector inlet. This is because blower and dust collector manufacturers do not adhere to standard dimensions on their inlet collars.

Due diligence on your part will avoid the installer's nightmare of not being able to make the initial connection when their duct order arrives. A construction drawing might state that the inlet is 12-inches in diameter, but it does not specify whether it is the ID or OD. Even if it does, don't trust it.

Have your equipment supplier measure both dimensions for you in the factory prior to shipping it. It is also critical that you take time after the equipment arrives to measure these actual circumferences yourself.

In over 75% of the cases when the ID or OD are not matched correctly to the duct-work, it becomes necessary for KVA Engineering to fabricate a simple custom adapter that facilitates the inlet connection.

For the OD, wrap a string around the collar until it meets itself. Then measure the length and divide by 3.14. For the ID, attach masking tape inside the collar until it meets itself. Then straighten it on your bench, measure it and divide it by 3.14.

Your figures will pinpoint the actual diameters that should be relayed to your duct fabricator. In addition, this approach is required when the inlet is out of round caused by damage during transport.
