RPB Nova 3 helmet/hood & RPB PX5 air supply both purchased as kit. Used off and on for about 6wks (fall 2022) and well maintained. Extra inner (8) and outer(10+) shields included with helmet. Air supply includes charger and 2 batteries. Both user manuals included. You will want to purchase new HE filters and prefilters though one is included. Asking price: together, $1100, or separate $400 helmet/hood ; $850 PX5, charger & belt. These both work fantastic and I highly recommend them. Great visibility and comfort. Helmet is easy to use and well thought out. PX5 supplies more than enough air even on lower settings and battery lasted through entire day's work on max setting. Thanks!
