Z4 – The lightest-weight welding respirator in the world in its class!

The Z4® from GVS / RPB is designed to do one thing, and do it very well:  Provide comfortable protection while welding.  A few features:

• Superior comfort. 
  • Very light-weight – only 28.4 ounces with ADF and cape when equipped with standard head suspension
  • Dual air-distribution system, delivers 75% of air supply to breathing zone and 25% across the visor to prevent fogging.
  • Adjustable head suspension system ergonomically balanced to reduce fatigue
• Flip-up visor.  When up, the visor reveals the clear safety lens, maintaining respiratory protection during inspection, grinding, etc.
• High protection with the following ANSI approvals:
  • Hearing (S3.19) when used in conjuction with the Quiet-Slim™ earmuffs.  (See below in Options list.)
  • Eye and Face (Z87+)
  • Welding Eye (Z87w)
• Great optics!  Highest quality wide-view ADF lens available.  (Additional details available on brochure under documents tab.)

Multiple breathing options, cape configurations, and accessories are available, as shown below:

• Head Suspension Options.
  • New!  Bump cap version shields your head from unwanted knocks
  • Original head-harness is fully adjustable for size
• Air Control Options.  Both supplied-air and battery-powered PAPR systems are available as follows:
  • Constant Flow Valve:  Basic supplied-air valve allows control of air volume in hood, but doesn’t provide air cooling.
  • C40:  Premium supplied-air valve allows full control over both air volume and temperature.  Cools up to 52 degrees!
  • HX5:  Basic PAPR option with single speed fan control, audible, and visual alarms.
  • PX5:  Premium PAPR option with multiple fan speeds, audible, visual, and vibratory alarms.  (Great for noisy environments!)
    • Note:  PAPR units do not require tethering to an air-line (making them very portable), but do not provide air cooling (can’t use with C40).
