难逃 车厢 (H)by清糖,禁止的爱 免费观看 百度百度The suspension-free RT Series PAPR hood provides high-performance respiratory protection through a comfortable sport neck cuff design that helps maintain positive pressure inside the hood and keep contaminants out. The patented over-the-top air delivery system supplies air over the user’s head, down the front of the lens, and into the breathing zone. This system helps to promote curvature of the hood for a better fit to the user’s head. This unique air delivery method provides for a positive seal, minimizes fogging of the lens, minimizes dry eyes and nasal passages, and provides a reservoir of breathing air to help maintain positive pressure.
- Widest lens on the market (135 sq. in.) provides for unobstructed visibility
