Cyclone and Dust Collection Research

Welcome to the updated Cyclone and Dust Collection Research web pages.

I spent at least six hours a day with more on weekends and holidays answering email and maintaining this site from 2000 through 2021. Lingering respiratory and joint problems have left me so little "up time" that as of January 1, 2022 my doctors required me to medically retire, so I will now only respond to a select few emails. I understand that finding information on these pages can be difficult, but please do your best to find answers before sending your questions to me. Although I am willing to do some consulting, I am not a free design service or engineering firm, nor can I walk each who read this site daily through the detailed steps needed to implement these solutions. I welcome and want to hear your suggestions, alternative solutions, and recommended improvements plus want to hear of any problems you may find with these pages that need repaired. I also need your help to become aware when something important comes up. It also makes my day to see your successes, pictures, comments, and financial support contributions.

In early 2000 I got very ill from a toxic wood dust exposure after I installed the top magazine rated small shop cyclone-based dust collection system. Disgusted I used my engineering background to do some real testing and measurement. I discovered the system I purchased moved less than one quarter of the advertised air flow and left my shop and home contaminated with a huge amount of toxic dust. Further testing showed virtually every other small shop air cleaner, shop vacuum, dust collector and cyclone-based dust collection system advertised badly exaggerated air volumes and most sold filters that freely passed the unhealthiest dust. I used my background as an inventor and university biomedical computer engineering instructor to invent a much better separating cyclone that separated five times better than its closest competitor. My respiratory doctor, a fellow woodworker was so impressed he talked me into writing an article with him that we shared on one of the early woodworking forums. We got over 10,000 emails, so wrote two follow-up articles then he gave up overwhelmed. In self-defense I created these web pages in 2000 to share our articles and answers to frequently asked questions. Many experts weighed in from all walks of life turning these pages into the dust collection information clearinghouse. As the volumes expanded my time went into ever growing amounts of email. There is no corporation or team that keeps up this site or answers the email, just one person with limited health and time. These pages never generated enough money to hire help or even afford the overhead to keep them up. I will use some of the time I previously put into emails into revising these pages to make them easier to use for both reference and as a tutorial.

Unless you properly title your email it can get lost. Even with special coding to disguise my email address the popularity of this site coupled with my email address being spread all over the Internet means I average over 6,000 mostly spam emails a day, so I pay a service to clean my emails. They delete all known junk mail, email with an invalid from address, and any other emails that are not titled either Customer Dust Collection Question or Customer Cyclone Question unless it comes from my small list of family and friend addresses. The deleted items never make it into my inbox, so I never see them. I try to answer all emails within two days and send automatic responses when I am away, so if you do not get a response, please ensure you are using a valid email from address and have your email properly titled.

You may send me email at: BPentz @ cnets . net (omit spaces) or Click here to email. Thank you for your patience.
