Air Mask

Powered Air Purifying Respirator(PAPR)

Feature This is an innovative personal respirator that blows a required amount of fresh and clean air, which is filtered by a small and light electric fan equipped with a high efficiency HEPA filter, into a connected soft silicone mask by gating with a user’s respiration.

Main Advantages

  • Advantages compared to wearing an industrial high-efficiency dust mask:

    • Solving difficulty in breathing and dizziness
    • Highly safe by maintaining the internal pressure of the face at positive pressure (static pressure)
    • A light, compact silicone mask that is worn inside a welding helmet and a face shield
    • Maximizing lifespan by using a high efficiency mechanical HEPA filter resistant to heat and moisture
    • An economic filter that can be used for a long time by filtering only the air a user breathes

  • Advantages compared to wearing a conventional powered respirator (PAPR) :

    • Solving the weight of a large motor, a filter and a heavy battery pack to provide a constant flow (120LPM or up) by lightening
    • Eliminating discomfort of wearing a heavy electric fan and a belt and connecting a stiff hose
    • Preventing backache and muscular-skeletal diseases caused by weight
    • It prevents the eyes and face from getting cold by flowing in cold air continuously to maintain the positive pressure in a mask
    • Increasing practicality at a reasonable price for expensive product

  • Safety

    • High efficiency HEPA filter with superior (99.95% or up) performance
    • Maintaining stable air flow and positive pressure with 2-channel (patented) fan unit design
    • Soft and good sealing clear silicone mask
    • Low carbon dioxide concentration inside a mask through a large ventilation valve
    • Stable fit and comfort of a lightweight fan unit seated behind the neck
    • Strong durability against impact and high temperature

  • Convenience

    • Easy to wear (not using a connected hood, a welding visor, a hose or a belt)
    • Excellent mobility and portability
    • Perfect compatibility with other protection devices (welding visors, safety helmets, protective glasses, protective shields, hearing protection devices)
    • Easy maintenance (filter replacement and mask removal and cleaning)
    • Easy, fast battery charging

  • Economic Feasibility

    • High life cycle of a high performance HEPA filter
      - Filtering only the required air by breathing detection (Sensor patented)
      - A filter that can be used longer than constant flow type PAPRs or dust masks
    • High usage efficiency of low capacity, lightweight battery
      - Providing only the required air by breathing detection
      - A durable battery that can be used for up to 8 hours
    • Low price and maintenance costs

Application

Welding, carpentry, manufacturing, smelting, construction, chemistry, mining industry, agriculture, processing factories, grinding, DIY, etc.
