Re: Any opinions about TREND airshields?

>HI Dick,
The two units really aren't in the same league. The Airmate is an industrial quality, NIOSH approved, long duty cycle, full helmeted power respirator. It will have longer useful life, has more filtration area, and provides total head protection. It's an excellent unit that, as you have found, can be refurbished occasionally for an indefinite life span. You've already bit the bullet on the original cost on this unit. IMO (based on my experience with its sibling the PowerStream), it is well worth the cost to refurbish it.
The Trend is a great unit, which much like the PowerVisor it is modeled on. It certainly is a better monetary value for the recreational user, and is more convenient to remove and replace in the course of intermittent woodturning. It is nice to have everything fully integrated into one head mounted unit. I have only examined a Trend, but haven't used one, but I imagine I will be replacing my PowerVisor (not my Airstream) when the PowerVisor finally is beyond refurbishing (which is coming closer every day because you can't get replacment parts any more and I've now used up my last neck seal and faceplate).
In the best of all possible worlds, it's nice to have one of each. One for intermittent work, the other when working for longer periods and when needing maximal head and face, as well as respiratory protection. But most will at best have only one, you already have one of the best positive pressure respirators ever made.
