Reusable Respirator for GasPowered Air Purifying Respirator (PAPR)Powered Air Purifying Respirator (PAPR) remove particulates (dust, fumes, mist) in the working environment using an electric fan and particle lter.After particles are removed by the lter, an electric fan sends the puried air to the wearer’s hood, facepiece, etc.PAPR provides high protective performance and enable much more comfortable breathing in comparison to particulate respirators.Powered Air Purifying Respirator for Toxic Gases (G-PAPR) are in accordance with JIS T 8154.Standards, Etc.34September, 2021(2021.9)See P.3 : Explanation of Marks Five-Digit No. : Product Code ★ : Made-to-OrderThe breakthrough time of a gas filter is influenced by a variety of factors, such as the gas concentration, breathing volume, ambient temperature and humidity. Among them, the gas concentration is the most influencing factor.In general, the breakthrough time of a gas filter is long at low gas concentration and short at high concentration. Measure the gas concentration at your workplace, and calculate the breakthrough time from the figure.When the accumulated record of used time reaches the calculated breakthrough time, please dispose the gas filter.1) When gas concentration is constant2) When gas concentration changesex) If a gas concentration in an atmosphere is 0.5 % and the breakthrough time is 50 min. against 2 % gas:ex) If a gas filter with 120 min. breakthrough time in 0.5 % gas is used for 20 min. in 1 % gas first, and then for 40 min. in 0.25 %, what is the remaining service life for 0.5 % gas?■ How to Calculate the Approximate Service LifeExample of Breakthrough Graph for Gas Filter Note: 1) This graph indicates that a gas lter can be used for approx. 150 min. if the concentration of cyclohexane is 0.02 % (200 ppm) in an atmosphere.2) The actual breakthrough time will differ depending on temperature and humidity at the workplace.The original performance = 0.5 % × 120 min. = 60 %min.The remaining performance = 60 %min. - 1 % × 20 min. - 0.25 % × 40 min. = 60 %min. - 20 %min. - 10 %min. = 30 %min.The remaining Shelf Life = = 60 min. 0.5 %30 %min.How to Read the Breakthrough Figures (not applicable for carbon monoxide gas lters)Direct-Mounting Small TypeX/OV lter for Organic VaporsTest Conditions: Temp.: 20 ± 2 ˚CHumidity: 50 ± 5 % RHAir ow rate: 30 L/min.The original performance = 2 % × 50 min. = 100 %min.If it is used against 0.5 % gas,0.5 %100 %min.= 200 min.Gas respirators remove airborne contaminants by a gas lter to provide clean air for breathing. Our gas respirators have superior reputation for quality excellence and are favored in a variety of industrial elds. Products by Shigematsu Works have been approved by the Japanese Ministry of Health, Labour and Welfare. Gas lters that are not prescribed by the Japanese Ministry of Health, Labour and Welfare are in accordance with JIS T 8152. Japanese Certification of Comformity■ Table 1 ComponentsDirect-Mounting TypePAPR consists of an electric fan, lter and facepiece, hood or face shield.The air puried by the particle lter is supplied to the facepiece, hood or face shield by the electric fan.Separate TypePAPR consists of an electric fan, lter, air supply tube and facepiece, hood or face shield.The air puried by the particle lter is supplied to the facepiece, hood or face shield through an air supply tube using an electric fan.■ Table 2 Face ShapeFacepiece TypeFull FacepieceHalf FacepieceLoose-Fit TypeHoodFace Shield■ Table 3 Minimum Air Flow Requirement (Limited to Loose-Fit Types)ClassMinimum Air Flow Requirement [L/min.]High Air Flow Type138Moderate Air Flow Type104■ Table 4 Class of Electric Fan Performance(Limited to Facepiece Types)ClassInternal Facepiece Pressure [Pa]Work Rate of Breathing MachineHigh Air Flow Type0 < Internal facepiece pressure < 400(1.6 ± 0.08 L/stroke) × 25 stroke/min.
