3M Versaflo TR-300 Kits - PAPR Powered Positive Air Pressure Respirators

Powered Air Purifying respirators (PAPRs); include a blower that draws contaminated air through filter/s to remove contaminants, supplying purified air to the user wearing either an open head top (loose-fitting hood) or tight-fitting facepiece. Like full and half facepieces, PAPRs are also available in ready packs to simplify the respirator selection process. 3M offers a range of ready-to-go PAPR kits: • Full facepieces for asbestos and dust applications • Half and full hood head tops ideal for the chemical and pharmaceutical industry • Helmets and face shields ideal for welding applications. The benefits of a PAPR are: • Protection factors up to 100+, based on the head top and filter/cartridge being used • Good option if using for long periods by reducing the weight of a filter carried on a facepiece • Helps prevent user fatigue with air moving around the head and face cooling the wearer • Available with a wide range of open and closed head tops (hoods & facepieces). • Respirators that rely upon positive airflow through a loose-fitting head top do not require face fit testing. These features make PAPRs ideal for industries such as; asbestos removal, pharmaceutical manufacture, smelters, waste control, land remediation, welding and agriculture. With any negative pressure or PAPR RPE, the selection and use of the correct filter for the contaminant/hazard is crucial. Filters are typically designed to handle particulates, gas/vapour or a combination of both particulate and gas/vapour. The life of a gas/vapour cartridge depends upon the temperature, humidity, concentration and type of contaminant, the filter class and the blower speed rate. Filters should be replaced regularly in accordance with an established filter replacement schedule identified in the initial risk assessment. AS/NZS 1716: 2012 recommends discarding your filter when any one of the following conditions exists: • The particulate filter makes it difficult to draw air through • According to the filter replacement schedule identified during the risk assessment • 6 months has passed since the sealed gas/vapour filter package has been opened • The expiry date on the filter has passed. In some instances, depending on the type of chemical hazard, filters must be changed out after each shift. If filters are to be re-used they should be stored in a sealed plastic bag or box. Filter classifications: Particulate Filters are classified as PAPR-P1, PAPR-P2, PAPR-P3: • PAPR-P1 filters handle mechanically generated particles • PAPR-P2 filters handle mechanical & thermally generated particles • PAPR-P3 filters handle mechanical & thermally generated particles Gas filters are rated Class 1, Class 2 or Class 3 according to their capacity to capture and hold certain gas/vapours The classification for gas & vapour filters is based on the groups of gases they are designed to be most effective against. Filters have colour-coded labels for easy identification of the different groups.
