• A, B, E, K Series: "Exclusive Guards" for Gas Vapor Protection

  

  Aug 19, 2025

  The letters A, B, E, and K represent different types of gases/vapors, while the numbers 1, 2, and 3 after them indicate increasing protection levels. The higher the number, the stronger the protection capacity (adsorption capacity), the higher the applicable pollutant concentration, and the better the resistance to environmental conditions (such as humidity), all of which are vital for the effectiveness of a Powered Air-Purifying Respirator. ​   A Series (Organic Gases/Vapors)​   The A series mainly targets organic gases and vapors, including substances such as benzene, gasoline, and acetone.​ A1: As the basic protection level, it is applicable to low-to-moderate concentration organic vapors when used in a Powered Air-Purifying Respirator.​ A2: With a higher protection level, the test concentration is usually more than 5 times that of A1, and it can function in high-humidity environments, such as painting workshops with high humidity and high concentrations of organic vapors, making it a suitable choice for a powered air purifying respirator welding in such settings.​ A3: Specifically designed for low-boiling organic vapors with a boiling point <65℃. Due to the extremely strong volatility of such gases, ordinary activated carbon has poor adsorption effects. A3 filter media use special adsorbents, providing more targeted protection in a Powered Air-Purifying Respirator.​   B Series (Inorganic Gases/Vapors)​   The B series mainly protects against inorganic gases and vapors, such as chlorine, sulfur dioxide, phosgene and other highly oxidizing or irritating inorganic gases.​ B1: The basic protection level, applicable to the protection of low-to-moderate concentration inorganic gases, such as small chlorine leaks in laboratories, when used in a powered air welding helmets.​ B2: With upgraded protection capability, it is applicable to medium-to-high concentration inorganic gases. The test concentration is more than 5 times that of B1, and it can pass high-humidity tests, performing well in scenarios such as leaks of high-concentration chlorine and sulfur dioxide in chemical production when used in a Powered Air-Purifying Respirator.​ B3: Targeting high-concentration or special inorganic gases, such as high-concentration phosgene and chlorine fluoride, it has higher requirements for protection capacity and chemical stability, usually used in extreme industrial scenarios with a Powered Air-Purifying Respirator.​   E Series (Acidic Gases/Vapors)​   The E series mainly deals with acidic gases and vapors, including hydrochloric acid, hydrogen fluoride, hydrogen sulfide, etc.​ E1: The basic protection level, which can be used for the protection of low-concentration acidic gases in a Powered Air-Purifying Respirator.​ E2: With a higher protection level than E1, it is applicable to medium-to-high concentration acidic gases and can effectively protect in high-humidity environments, such as pickling workshops and high-humidity + high-concentration acid mist environments near electroplating tanks, when used in a powered hood respirator .​ E3: Targeting high-concentration strong acidic gases, such as concentrated nitric acid vapor and high-concentration hydrogen fluoride, the filter media contain a higher amount of alkaline adsorbents (such as potassium hydroxide) with larger reaction capacity, applicable to strongly corrosive chemical environments with a positive pressure powered respirator.​   K Series (Ammonia and Amine Gases/Vapors)​   The K series mainly protects against ammonia and amine gases/vapors, such as ammonia, methylamine, ethylamine and other alkaline gases.​ K1: The basic protection level, applicable to the protection of low-to-moderate concentration ammonia or amine gases in a papr fitting.​ K2: With a higher protection level, it is applicable to medium-to-high concentration ammonia or amine gases and can effectively adsorb in high-humidity environments, such as fertilizer factories and humid environments with ammonia leaks in cold storage, when used in a purifying respirator.​ K3: Targeting high-concentration amines or mixed amine gases, the adsorbent has stronger specific adsorption capacity for amines, applicable to amine synthesis scenarios in fine chemicals with a Powered Air-Purifying Respirator.​ III. The "Golden Rule" for Selecting Respiratory Protection Filter Media​ When actually selecting respiratory protection filter media, especially for a Powered Air-Purifying Respirator, we need to comprehensively consider the type of pollutants in the working environment (whether particulates or gases/vapors), concentration, and environmental conditions (such as humidity). For example, in a high-concentration organic vapor environment with high humidity, A2 is a more suitable choice for the filter in a Powered Air-Purifying Respirator; for low-boiling organic gases, A3 should be selected. Only by choosing filter media that match the scenario can we truly ensure our respiratory safety when using a Powered Air-Purifying Respirator. ​ These seemingly complex labels are actually "compasses" for protecting our respiratory health, particularly when using equipment like the Powered Air-Purifying Respirator.

• CE Testing Requirements for Powered Air Purifying Respirators (PAPRs)

  

  Jul 30, 2025

  When it comes to personal protective equipment (PPE) designed to safeguard workers from harmful airborne contaminants, Powered Air Purifying Respirators (PAPRs) stand out as critical tools in industries ranging from manufacturing to healthcare. But to enter the European market, these life-saving devices must meet stringent CE certification requirements. Let’s break down the key testing standards and obligations that manufacturers need to know. ​ Understanding the Regulatory Framework​   First, it’s essential to recognize where PAPRs fit within EU regulations. As devices designed to protect users from respiratory hazards—including dust, fumes, and toxic gases—PAPRs are classified as Category III PPE under Regulation (EU) 2016/425. This classification applies to high-risk equipment where failure could result in serious injury or death, meaning compliance is non-negotiable. ​ Category III PPE requires rigorous testing and oversight by a Notified Body—an EU-accredited organization authorized to verify compliance. Self-declaration is not sufficient here; third-party validation is mandatory.​   Core Standards: EN 12941 and Beyond​   The backbone of CE testing for PAPRs is EN 12941:2001+A1:2009, the European standard specifically governing powered air-purifying respirators. This standard outlines performance, safety, and design criteria, while additional standards address specific components like filters and batteries. Let’s dive into the key testing areas: ​ 1. Airflow Performance: Ensuring Reliable Protection ​ At the heart of a PAPR’s functionality is its ability to deliver a consistent supply of filtered air. Testing here focuses on:​ Minimum airflow rates: For half-masks, the minimum is 160 L/min; for full facemasks, it’s 170 L/min. These rates must remain stable within a 10% tolerance during 30 minutes of continuous operation.​ Positive pressure maintenance: The respirator must maintain a positive pressure (≥20 Pa) inside the mask to prevent unfiltered air from leaking in—even if there’s a small gap (10% leakage) between the mask and the user’s face.​ Flow stability under varying conditions: Tests simulate different breathing rates (from 15 breaths/min at rest to 40 breaths/min during heavy work) to ensure airflow doesn’t drop dangerously.​   2. Protective Efficacy: Blocking Harmful Substances ​ A PAPR’s primary job is to filter out contaminants, so testing verifies both the device’s seal and the performance of its filters:​ Total leakage testing: Using aerosols (like sodium chloride or DOP), testers measure how much unfiltered air enters the mask. For the highest protection levels, total leakage must be ≤0.05%.​ Filter compatibility: Filters must meet standards like EN 149 (for particulate filters) or EN 14387 (for gas/vapor filters). For example, a P100 filter must capture ≥99.97% of 0.3μm particles.​ Seal integrity: The connection between the filter and PAPR host is tested for pressure decay—allowing no more than 50 Pa loss per minute to ensure no bypass.​   3. Mechanical and Structural Safety ​ PAPRs must withstand harsh working conditions without compromising user safety:​ Material durability: Components like masks and hoses undergo extreme temperature cycles (-30°C to +70°C) and UV exposure (72 hours) to check for cracking or deformation.​ Strength testing: Straps, mask attachments, and filter connections must resist forces like 150N (for head straps) and 50N (for filter interfaces) without breaking.​ Impact resistance: Full facemask lenses are tested with a 120g steel ball dropped from 1.3 meters to ensure they don’t shatter.​ 4. Electrical Safety: Powering Protection Safely ​ Since PAPRs rely on motors and batteries, electrical safety is paramount:​ Insulation and grounding: Motors must withstand 2500V AC for 1 minute without breakdown, and metal components must have a ground resistance ≤0.1Ω.​ Battery performance: Batteries (often lithium-ion) must pass EN 62133 tests, including short-circuit, overcharge, and crush scenarios, with no fire or explosion risk. They must also provide at least 4 hours of runtime at rated flow.​ EMC compliance: To avoid interference from tools or radios, PAPRs must meet EN 61000 standards for electromagnetic compatibility.​ 5. Durability and Environmental Adaptability ​ PAPRs are built for long-term use, so testing ensures they stand the test of time:​ Aging tests: Motors run continuously for 500 hours with ≤10% airflow loss, while batteries retain ≥80% capacity after 300 charge cycles.​ Extreme environment performance: Devices must operate in -30°C cold and 40°C/90% humidity without airflow drops or electrical failures.​ Special Cases: Tailoring to Unique Environments​ Certain industries demand extra testing:​ Medical settings: PAPRs used in healthcare must meet EN 14683 for biocompatibility (e.g., no skin irritation) and may require antimicrobial coatings.​ Explosive environments: For use in zones with flammable gases, PAPRs need ATEX certification (EN 13463) to prevent sparks or static discharge.​​   CE testing for best powered air purifying respirator is rigorous, but it’s rooted in a simple goal: ensuring these devices protect users when they need it most. By adhering to EN 12941 and related standards, manufacturers not only gain access to the  EU market but also demonstrate a commitment to safety that builds trust with workers and employers alike.
