This product (PRF-103RAD）is a kind of powered air purifying solar auto-darkening welding helmet. It provides the water proof main body design which can endure the strict cleaning and sterilizing. Two or three of the filter slots can be used at the same time. The respirator is light in weight, comfortable in wearing, human body engineering design which can uniformly distribute the weight, easy in operation integrating respiratory, skin and eye protection, in welding, glass auto-darken，switch time< 0.1 ms, dark：9-13（knob rotate outward），airtight, light in weight, easy in operation, 0.3μm filtrating precision. Air flow is huge, 160-280L/Min, and adjustable (clockwise regulate big flow and anti-clockwise regulate small flow). Battery can supply power 6 to 20 hours consecutive operation, if air flow regulate maximum, the lithium battery can work for 6 hours continuously, while air flow regulate minimum, 20 hours. If work over 6-20 hours consecutively, a backup battery is needed. It will buzz automatically when power is low. Air flow from the top down can avoid fogging.
This product is used in many kinds of welding condition that head will not be accidentally hurt and many kinds of gas protecting welding （TIG、MIG、MAG）of adverse electric welding machine as well as all kinds of arc welding. This product does not provide protection against: Autogen welding or Laser welding! This product is adaptive to various particles (dust, fog, smoke and the like) and many kinds of poisonous and harmful ill odors. It is the best choice for preventing pneumoconiosis and protecting eyes of welder.
Three choices of filters, they are 103HD, 103G and 103W.
And it is unsuitable to anoxic (i.e. oxygen content less than 18%) or IDLH concentration (Immediately Dangerous to Life and Health).
Weight of PRF-103R respirator (including battery, excluding filter case): 1100g.
Weight of AD air supply auto darkening helmet: 600g.
