A Great Snug Fitting Mask with Changeable Filter - Optimal Adjustment - Good Stability - Easy Maintenance - UNE-EN 140: 1999 - CE Marked

Description and CharacteristicsThe mask (composed of face mask and two filters) covers the user's nose, mouth and beard and is manufactured of strong, lightweight materials that are non-hazardous for health and hygiene.Mask body:The mask body is made of flexible black rubber. Both the material and its shape and dimensions allow a snug, leakproof fit, thereby preventing air leaks toward the inside where the mask touches the face. The mask has a centre hole to house the exhalation valve holder plus two additional holes on the sides to adjust the connectors for the inhalation valves.Valve holder:The mask is equipped with an exhalation valve that allows the air to be expelled easily when breathing. The valve holder for the exhalation valve is manufactured of dieinjected polyethylene.Harness:The mask harness is manufactured of die-injected black high-density polyethylene (HDPE) and covers the entire front of the mask body. This design ensures that the force exerted by the elastic straps is evenly distributed over the entire mask body for a snug, comfortable fit.FilterThe filter is cylindrical (diameter 79 mm) with a black high density polyethylene (HDPE) body. The filter is composed of two white fabric filtering discs inserted in the inner faces of the cover and the base plus highly absorbing Type  A activated charcoal. The filters are fit into the mask by screwing the connectors.CE certificationStandards: UNE-EN 140: 1992UNE-EN 141: 1992Directive 89/686/CEERegulatory agency 0159Certificate no. 21205598Respiration resistance:Sinusoidal flow 25 x 2 l/min:Inhalation: 0.52 mbarExhalation: 1.64 mbarContinuous flow inhalation:At 30 l/min: 0.11 mbarAt 95 l/min: 0.33 mbarCO2 content (dead space): 0.60 %Leaks to inside (tightness): < 2 %
