Hi, Kate.
<div><br>
</div>
<div>An air compressor and a leaf blower are substantially different in the intensity of air stream. The air compressor is the pneumatic analogue to a hydraulic pressure washer.</div>
<div><br>
</div>
<div>Next time the the vehicle is in the same shop as the air compressor, check it out. I think you’ll see it has the capacity to dislodge debris quite effectively.<br>

Our specific concern is that it looks like we are inadvertently spreading Arthraxon in tire treads, and we thought a water pressure washer might work better than air to get mud out of the tires...</div>
