  • Features

    Full Face Mask (Facepiece)

    • One-size fits all, made of EPDM, excellent all-round capacities of weather properties, resistance to temperature, tear, abrasion, compression, steam, and various acids & alkalis to provide full protection for the entire face of the user.
    • Visor lens is treated with anti-fog, made of polycarbonate offering superior resistance to scratch, shock, and heat resistance.
    • View angle is wide and offers an extended field of view to improve situational awareness.
    • Integrated Inner Piece is provided along with perspiration drain to avoid skin irritation.
    • Equipped with an ambient air switch enabling the user to have the mask fully donned and still breathe ambient air to save the compressed air in the cylinder.
    • Equipped with speech device.

     

    Demand Valve

    • Lung governed second stage regulator for various rates of flow demand
    • One-touch disconnection on the mask offers secure and quick operation
    • First breath open (FBO) activation
    • Bypass valve for manual control of airflow
    • Flow rate and Static positive pressure maintained in the mask are compliant with EN 137 standard.
    • Peak Flow Performance: 450 l/min (± 10%)
    • Bypass Flow: 60 l/min - 450 l/min. (± 10%)
    • Static positive pressure: < 5 millibars
    • Push button to shut off the air supply in standby mode.

     

    Warning Device & Pressure Valve

    • Warning whistle is integrated with the first stage regulator.
    • Whistle generates alarm sound when the air pressure drops below about 55 Bar ± 5 bar and measure at least 90 dBA sound at the ear of the user within 1 meter distance.
    • Flashing locator light aids the auditory alarm as it changes from green to red, and it help to easily identify the location of the user in dark.
    • Pressure reducing valves is a non-adjustable spring loaded piston mechanism.
    • Pressure reducing valve serves as the first stage regulator effectively controls both 200 or 300 Bar cylinders.

     

    Pressure Gauge

    • Gauge offers a bright luminous display and shatterproof plastic face and rubber protection cover against shock and scratch.
    • Gauge can be firmly secured and freely transferrable to either side of the shoulder harness strap.
    • Pressure indicator is in BAR.

     

    Harness

    • Made of flame resistant, light weight material for excellent weight distribution of the apparatus.
    • Adjustable shoulder strap and waist belt are fast-tightening for easy donning and doffing.
    • Adjustable cylinder strap to various sizes of cylinders with safety lock buckles.

     

    Frames

    • Frames are ergonomically designed to offer proportionate load balance, maneuverability and comfort.
    • Made with materials that are fire proof, non-static, non-conductive, light-weight, resilient and high impact strength.

     

    Other Accessories

    • Hose is made of non-flammable, acid and weather resistant and reinforced materials.
    • Buckles and other accessories are made of stainless, aluminum.

  • Options

    Rescue Mask

    • Half-face mask for rescuers

    Vessel
