Description

The mask is intended to protect the skin cover of the face, breathing and visual organs in the atmosphere that is immediately dangerous to life and health. It is suitable for rescue, maintenance and service operations.

 

GENERAL RECOMMENDATIONS FOR USAGE

The sizes and proportions of the human face vary essentially. If the mask is too large or too small, it may slip aside, overburden and limit the field of vision, and thus lose its protective capability because of a loose fit. To provide for the user's maximum comfort, DEZEGA offers 6 size combinations: 3 mask body sizes and 2 inner mask sizes. It is essential to choose the correct size combination, taking into account the shape of the face and other individual features, for a tighter fit along the obturator line. For a quick choice, try on the medium size of the mask body and the medium size of the inner mask first: this is the most common combination.

DEZEGA recommends using the special sizing pattern to choose the right size of the mask body and inner mask.

To prevent the mask from fogging up during use, apply DEZEGA Clear-Vision solution to the inner surface of the visor and impregnate the visor wipe with it. During long operations, the visor might fog up from the inside. To remove the condensation, turn the handwheel of the wipe: it will renew the layer of protective DEZEGA Clear-Vision solution on the visor.

AVAILABLE SIZES

  • 3 sizes of the mask body are made of silicone or EPDM (ethylene propylene diene monomer): small (S), medium (M-L) and large (XL)
  • 2 sizes of fit-all inner mask: small (S) and medium (M)

 

FEATURES AND BENEFITS

  • Improved visor wipe system minimizes fogging up and the condensation is removed easily
  • The handwheel connects to the wipe directly, and not through the visor, which  precludes the loss of tightness because of the wear of the connecting joint
  • Wide and flexible belts of the 5-point headgear made of EPDM or fabric net tightly fix the mask on the head and evenly distribute the pressure over the head along the contact line
  • Buckles and fastenings of the headgear do not become hot and do not burn the face where they touch the skin directly: they are made of heatproof materials without metal parts
  • Shock-proof polycarbonate visor is resistant to scratches, flame and heat flow. Its rectangular shape provides for at least 70% of the natural field of vision, which improves both front and side visibility
  • High speech intelligibility due to larger speech diaphragm
