Operators claim that the RPB Nova 3 is the lightest and most comfortable heavy industry respirator they've worn. The ratchet padding system provides a customizable fit and molded side pads absorb sound, protecting against hearing loss. Its unique helmet design distributes weight evenly across the head and shoulders, keeping the center of gravity low, eliminating top heaviness and relieving the operator from aches and strains on their neck. Visibility is at the forefront of the Nova 3 design. With the unique tear off cassette lens system, operators can easily remove the outer lens layer for complete crystal-clear vision, increasing productivity by over 45 minutes per day. The superior operating window optimizes peripheral vision and allows 30% more downward vision than other respirators on the market. With a tough helmet shell and easily replaced parts, the Nova 3 works as hard and as long as you do.
