Hi,
In addition to hobby woodworking I participate in a club that was formed for the enthusiasm of paleontology. The club has a long association with official science organizations, and as such we are loaned, and permitted to prepare fossils in service of the associations that mentor the activity.
The club wants to upgrade from basic shop vac status so I brought my CT26 to the prep lab so they could observe the wonders of combining HEPA filtration with high suction capacity.
We do not have the budget to go all out with an industrial style duct system and an big collector placed where no one can see or hear it.
The dust created is minimal in volume, we are working with a tiny needle like air chisel to dislodge the mineral matrix surrounding the bones, so the CT26 collected everything and the HEPA filter was considered a huge upgrade.
The idea of using a modern marvel HEPA dust collector inside the lab has been regarded as an appealing upgrade to the present system.
With the practical needs taken care of, attention turned to how quiet the CT26 was compared to expectations or apprehensions. The low noise was greatly appreciated.
The club seems interested in buying two dust extraction systems and has asked me to learn what products might meet the needs of extraction and filtration while being exceptionally quiet.
I am wondering if the CT series is the quietest or if some of the close competitors might be quieter. For example; Are the CT extractors quieter than the Fein extractors.
I was surprised that I could not find any dB specs for any of the small workshop dust extractors that I looked in to.
We understand that using the extractor is usually coincident with the use of a noisy tool, so we are not especially concerned about the operator of the tool, who will know when to use hearing protection etc. but our lab is located in a museum facility and we would like to be helpful and cooperative in terms of minimizing disruption to the people we share the building with.
Has anyone had an opportunity to compare these extractors in terms of noise?
Thank you!
