The past month I’ve been having a great email conversation with Dick Wynn (Wynn Environmental) as I continue to develop my design for my dust collection system. Rather than the typical HF modification kit that replaces the filter bag with a large canister, I’ve chosen to eliminate much of the standard hardware only using the blower and substituting a Oneida Super Dust Deputy and a Wynn 9L300NANO filter. This should give me a straighter airflow and better performance.
Adding to that conversation Dick and I are now discussing an added and different approach to improving the air quality in my shop. Rather than buying an off the shelf air filtration unit for a few $100 and hanging from the ceiling, I’m looking at building a sort of HVAC—less the heating—system that would collect air from under my workbenches, filter it to Merv15, then pump it out above my work areas. The benefit of such would be that instead of pulling dusty air from the ground and work area tops into my breathing space, I’ll have a downdraft sucking the dust away and a positive air pressure from the top pushing the dust down.
This is only in brainstorming territory at present, once I finish my primary dust collector system I’ll start experimenting on the shop downdraft idea to test out the viability of such. If it works it will be another tool in my shop to me healthy. —another bit of news one of my doctors, who specializes in respiratory aliments, is interested in what I’m doing so I’ll have yet another expert’s advice to consider.
While I will not likely document to the level of a Bill Pentz for these projects as I build and operate tem I’ll photograph & document the design and results to share.
For those wishing to ask questions I’ll do my best to answer. However, I’m not a Bill Pentz and don’t spend a lot of time researching the details in this area. Other than the designs I’m creating, I’ll likely point you to Bill Pentz, Steven Emmons, Stumpy Nubs, etc. websites.
