Duram COGO

Duram COGO

A personal respiratory protective device with visor, hood and built-in filter for escape from fire. Protects against smoke and CO (Carbon Monoxide) inhalation.

Complies with European Standard EN-403.

FEATURES

  • Easy to use. Dons within seconds. No adjustment straps
  • One size fits all
  • Strong, fire-resistant, elastic rubber hood, protects the entire head and seals comfortably at the neck
  • Large visor, made of flame retardant transparent film, allows a wide field of view
  • A unique breathing device (patent pending), enables rapid exhalation and improves the physiological conditions for the user, preventing built-up of heat or vapour inside the mask
  • A filtration unit containing low pressure electrostatic particle filter, impregnated charcoal cloth layers to absorb toxic gases and catalyst for Carbon Monoxide Oxidation
  • Training model available
