• PAPR Hard Hat: The Rigorous Testing Journey

  

  Dec 01, 2025

    In the field of industrial protection, powered purified air respirator is undoubtedly a robust piece of equipment that safeguards the health of workers. As a key component of the system, the hard hat serves as the first and most crucial line of defense for head safety. Many people regard a hard hat as just an ordinary "hat", but behind its safety functions lies a series of rigorous testing processes that are almost "demanding"—each one is related to life safety and allows no carelessness.   As a key component with core safety helmet functions, the primary mission of a hard hat is to resist external impact and penetration. The stability of its performance in high and low temperature environments is a litmus test for its quality. In low-temperature environments, most materials become brittle and hard, and their impact resistance decreases significantly, which is particularly dangerous for workers operating in cold workshops or outdoor freezing environments. The low-temperature impact resistance test simulates extreme scenarios at temperatures as low as minus 20℃ or even lower. The hard hat is fixed, and an impact hammer of specified weight is dropped from a specific height. The test observes whether the hard hat can effectively absorb impact energy, ensuring that the shell does not crack, the lining does not fall off, and the force on the head is minimized.   Contrary to low-temperature environments, high-temperature environments can soften materials and reduce their strength, which also impairs the protective performance of hard hats. For the high-temperature impact resistance test, the hard hat is placed in a high-temperature chamber at over 50℃ for a constant temperature period to fully adapt to the high-temperature environment, and then the impact test process is repeated. This test is mainly targeted at working scenarios such as metallurgy, casting, and high-temperature baking. It ensures that the hard hat can still maintain stable impact resistance under high-temperature exposure and will not "fail" due to material softening. After all, the protection of the powered face shield respirator is integrated, and a weakness in head protection may greatly compromise the protective effect of the entire system.   If impact resistance testing safeguards "surface" safety, then penetration resistance testing defends against "point" threats. In scenarios such as construction and mechanical processing, falling or splashing sharp objects like steel bars, nails, and fragments can easily cause fatal injuries to the head. The high and low temperature penetration resistance tests also simulate extreme temperature environments. A sharp penetration cone is used to impact key parts of the top or side of the hard hat at a specified speed and force. The requirement is that the penetration cone must not penetrate the shell, let alone touch the test model simulating the head. This test directly relates to the ability to resist "precision strikes" from sharp objects and is one of the core indicators of the hard hat's protective performance.   In addition to specialized tests for extreme environments, the aging resistance test is a strict assessment of the hard hat's "service life". During long-term use, hard hats are affected by various factors such as sunlight exposure, humidity changes, and chemical gas erosion. The materials may gradually age and become brittle, and the protective performance may slowly decline. The aging resistance test uses methods such as ultraviolet radiation and humidity-heat cycling to accelerate aging, simulating years of service environment. After that, impact resistance, penetration resistance and other performance tests are re-conducted to ensure that the hard hat maintains qualified protective levels throughout its specified service life and avoids potential safety hazards of "seeming intact but actually failing" due to material aging.   From low temperature to high temperature, from impact resistance to penetration resistance, and to long-term aging resistance, the hard hat in High-Flow PAPR System has become a "head safety shield" for workers after going through this series of rigorous "tempering" tests. Behind each test data is respect for life; every hard hat that passes the tests is a fulfillment of the safety commitment. Therefore, when we see workers busy at their posts wearing hard hats, we might as well have a deeper understanding—this "hat" has gone through countless trials, all to safeguard every safe operation.If you want know more,please click www.newairsafety.com.

• Differences Between TH3 and TM3 in PAPRs

  

  Nov 11, 2025

     Among the protection level designations of PAPRs (Powered Air-Purifying Respirators), TH3 and TM3 are two categories that are easily confused. Many practitioners may wonder when selecting products: if both are "Level 3" protection, why is there a distinction between "TH" and "TM"? In fact, these two designations are not randomly assigned, but are specialized protection levels defined based on internationally accepted classification standards for respiratory protective equipment, targeting different environmental risks, pollutant types, and usage requirements. Clarifying the core differences between them is crucial for accurately matching PAPRs to work scenarios.   To understand the difference between the two, it is first necessary to clarify the core definition of the designations: the "3" in TH3 and TM3 represents the intensity of the protection level (usually corresponding to protection requirements for high-concentration or long-term exposure scenarios), while the prefixes "TH" and "TM" directly point to the core risks of the protection scenarios. "TH" is the abbreviation of "Thermal/High-humidity", which is mainly suitable for high-temperature, high-humidity scenarios accompanied by particulate pollution; "TM" is the abbreviation of "Toxic/Mist", focusing on environments with toxic gases, vapors, or misty pollutants. In simple terms, the essential difference between the two lies in "different core risks of the protection scenarios", which in turn leads to differences in key performances such as design, filtration system, and materials.    In terms of applicable scenarios and protection objects, the boundaries between TH3 and TM3 are clear and highly targeted. The core application scenarios of TH3-type PAPRs are concentrated in fields with high-temperature, high-humidity and particulate pollution, such as blast furnace maintenance in the metallurgical industry, boiler maintenance, and ceramic firing workshops. In these scenarios, the ambient temperature often exceeds 40°C, the relative humidity is over 80%, and there are a large amount of metal dust and slag particles. Therefore, the protection focus of TH3 is "high-temperature resistance + damp-heat protection + particulate filtration", which needs to ensure that the motor does not shut down at high temperatures, the mask does not fog up, and the filter cotton does not fail due to moisture absorption. The TM3-type air papr, on the other hand, are mainly used in scenarios with toxic and harmful gases/vapors or misty pollutants, such as solvent volatilization operations in the chemical industry, paint spraying, and pesticide production. The pollutants are mostly organic vapors (such as toluene and xylene) and acidic droplets (such as sulfuric acid mist). Its protection core is "efficient toxin filtration + anti-leakage". The filtration system needs to be equipped with a special toxic gas filter canister (instead of a simple filter cotton), and the mask has higher requirements for sealing performance to prevent toxic substances from infiltrating.   Differences in design processes and core performances are the technical support for TH3 and TM3 to adapt to different scenarios. TH3-type papr respirators focus on "environmental stability resistance" in key components: the motor uses high-temperature resistant materials (such as insulation coatings resistant to 120°C), the mask is equipped with an anti-fog coating and a ventilation and diversion structure, the filter cotton uses hydrophobic materials to avoid clogging due to moisture absorption, and some models also add heat dissipation holes. The design focus of TM3-type PAPRs is "toxicity prevention and sealing": the toxic gas filter canister adopts a layered adsorption structure (such as a combination of activated carbon and chemical adsorbents), and the adsorption materials are customized for different toxic substances; the fitting part of the mask and the face uses high-elastic silica gel to reduce gap leakage; some high-end models also integrate a gas concentration alarm function to monitor the failure risk of the toxic gas filter canister in real time. In addition, the certification standards for the two are also different - TH3 needs to pass the particulate filtration efficiency test in high-temperature and high-humidity environments, while TM3 needs to pass the penetration rate test of specific toxic gases.   Confusing TH3 and TM3 during selection may lead to "protection failure" or "excessive investment". If a TH3-type PAPR is incorrectly used in a chemical spraying scenario, it can only filter paint mist particles but cannot adsorb organic vapors, leading to inhalation of toxic substances. If a TM3-type PAPR is selected for boiler maintenance scenarios, although it can filter dust, the motor is prone to overload in high-temperature environments, and the toxic gas prevention function of the filter canister is completely redundant, increasing equipment costs. Therefore, the core principle for selection is to "target the core risks of the scenario": first determine whether the environment is "high-temperature and high-humidity + particulate matter" or "toxic gas/mist + particulate matter", then select TH3 or TM3 accordingly. In short, the difference between TH3 and TM3 is not "level height", but "scenario adaptation". Accurate matching is the key to respiratory protection.If you want know more，please click www.newairsafety.com.

• What is PPE? Understand PAPR’s Key Role

  

  Sep 29, 2025

  PPE (Personal Protective Equipment) is the last line of defense for workers against workplace hazards. It refers to equipment worn to mitigate physical, chemical, biological, and other forms of harm, covering multi-part protection such as head protection (e.g., hard hats), eye protection (e.g., safety goggles), torso protection (e.g., protective clothing), and respiratory protection (e.g., face masks). Its core purpose is to "targeted hazard mitigation" rather than replacing safety management measures. ​ Among various types of PPE, respiratory protection equipment directly safeguards a critical aspect of life. Ordinary dust/mist masks rely on proper fit to function, but in high-risk scenarios, powered air respirator emerges as a more reliable option. Unlike traditional face masks, it is an active protection system composed of an "air supply unit, filter component, and face shield/hood" — the air supply unit generates positive-pressure airflow via a motor, which, after passing through the filter to remove hazardous substances, is continuously delivered into the face shield. This design not only prevents the intrusion of external contaminants but also reduces breathing resistance for the wearer.​ The core advantage of papr air purifier lies in its "dual benefits of high protection + comfort". Compared to ordinary face masks, it can filter higher concentrations of dust, toxic gases, or bioaerosols. Additionally, its positive-pressure design avoids reduced face shield fit caused by the wearer's inhalation. Meanwhile, the continuous airflow minimizes stuffiness, making it suitable for long-duration tasks (e.g., chemical maintenance, high-risk epidemic care). It is particularly ideal for individuals with facial hair who cannot wear ordinary face masks properly. ​ However, the use of air papr must comply with professional standards — a requirement common to all PPE management. Firstly, it is essential to select filter materials (e.g., organic vapor filter cartridges, particulate filter cotton) that match the workplace hazards. Secondly, regular checks of the air supply unit's battery level and filter life are necessary to prevent equipment failure. Before use, a "positive pressure test" should be conducted to ensure no leaks in the face shield — these steps align with the logic of impact testing for hard hats and pressure resistance checks for insulated shoes, all of which are critical to ensuring PPE effectiveness.​ Overall, PAPR is a typical representative of "specialized protection" in the PPE system. Its introduction fills the gap left by ordinary respiratory protection equipment in high-risk scenarios. Nevertheless, whether choosing PAPR or basic PPE, the core principle remains unchanged: first, identify hazards through risk assessment, then select appropriate protective equipment, and finally implement usage and maintenance procedures — only in this way can PPE truly serve as the "safety armor" for workers.If you want knon more, please click www.newairsafety.com.
