I made the decision to completely reupload three of my latest videos to fix the audio and add in a few more snippets - this is the last of those three. I have unlisted my previous Supplied Air Respirator video, so if you would like to still watch that one or read the comments, this is the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SAvGCHvCjKw.html Thank you for the overwhelming support in the comments and encouragement to keep on making more videos and improving along the way!
I really like this idea and have been looking for a solution myself for hobby painting at home, think the only thing i would want to change is the hose to somethibg a bit more rugged. I was looking at using an ac centrifugal fan but that inline fan seems like a better idea
I agree that the tubing is a bit thin, but that also makes it easy to work with. Vinyl duct is still pretty light, and will just put a bit more weight on your head. An AC centrifugal fan should be fine if it has a similar or greater rating than the inline. The inlines generally are a bit cheaper though.
Another issue about piston compressors is duty cycle which can be hard to get this percentage from the manufacture! Duty cycle of average piston compressor is less than 50% which is the compressor must rest for 50% of the time & main reason why you have a large receiver otherwise it will over heat leading to damage & failure! So you cannot run the compressor all the time so you will have to increase the size of the compressor to nearly double. Another way of looking at it is the compressor will need more servicing or becomes disposable after 18 months! Yes I have worked with customers who go for the disposability which I feel is mad!
So essentially even the "cheapest" compressors are probably not the cheapest long-term. Even just the large air compressor needed is enough of a barrier of entry to stop most people, let alone all the other accessories needed to output clean air.
@@ArisAlderI have seen so many compressors for repair for this purpose. Customers are never too happy once they find out but got to cover myself as I know they will be back. Same with grit blasting & laser/ plasma cutter.. Unless you factor the 50% storage or get a stainless steel / cast iron with 90%+ Your option is definitely the cheapest
In an ideal situation you would actually be doing both. The more professional example would be using a fume hood for chemicals, and a respirator would further increase safety in that situation. In situations like painting, welding, or cleaning lots of resin parts (think more industrial scale), it could be very costly to install a sufficient ventilation system, which makes a supplied air respirator reasonable.
