Hi Marc- You would think it would,,, as its that collapsible AC ducting 4".
As with PVC tube, some say yes, others say it's all B/S- I suppose to be on the safe side it wouldn't take much to do, never been zapped yet, but if it exploded it would be a drama. You probably remember I built this one years back and have added 2 more tubes since, which works much better--
Its a "downdraught" set up, air is drawn down then up through the 4 tubes to the "Fan Box" and then expelled outside, through the shed wall.
