This temp is after the air has been cooled by the clothes. I'm absolutely certain that the air coming off the heating element is hotter than that, even in a bachelor quality unit. It's interesting that the commercial folks use 300 degree steam, but I also suspect that the air coming off of that steam HX is less than 300 - that would be pretty hot. I got no reasonable way to stick a probe in mine. It's bolted to the top of our washer, and the WAF involved in moving it would be well into the negative numbers. If 170 degree air is reasonably close to what you need, then it's probably possible to get that off of an automotive radiator. They give you quite a bit of surface area. If you need 250 degree air, then it's not practical in my view.
