Now as for the accessories I suppose you would have to be more specific. But if your talking about atomizers etc the reason they won't state on their site if it will work with the Janty Dura vs the 510 from example is because of copyright and trademark issues. Sometimes they can't legally state it works on various products, just the way they can't sell the 510 as the Dura even though we all know it's basically the same thing. Dura is a product of the Janty Corp.
Hope that helps
