Think its the little dinky model similar to what Drieaz used to sell. Found the airflow was quite narrow as opposed to the larger models where it fans out.
The small dri-eaz is a crazy low .25 hp or 200w ...
The s10 above is 1000w ... should be same as about the mid setting on the 1.5hp.
should still blow picture frames off at 20 feet .
Had a tiny dri-eaz , even though its a waste of money in some ways ... i grew to like it for the occasional job where u had to carry it in one hand a couple of hundred yds and then up 3 flights ..
