AX and AXP filters for respiratory protection: the complete guide

The workplace safety is a top priority, especially in environments exposed to hazardous gases, organic vapors, or particulates.

Among the most effective personal protective equipment (PPE) for respiratory safety, AX and AXP filters for respiratory protection play a crucial role. These filters not only shield against organic vapors with a low boiling point, but also provide a barrier against contaminants that pose serious health risks.

In this article, we’ll explore why they are essential, when to use them, and the certifications that ensure maximum reliability.

 

What are AX and AXP filters for respiratory protection?

I AX and AXP filters for respiratory protection are devices designed to protect respiratory systems from organic vapors and other harmful substances. Let’s take a closer look:

1. AX filters: Specifically designed for organic vapors with a boiling point below 65°C. These include volatile compounds like acetone, ether, methanol, and formaldehyde, often found in industrial environments or chemical laboratories.
2. AXP filters: Provide combined protection against organic vapors and particulates, ensuring enhanced safety in mixed exposure environments.

Both filters, identifiable by their colors brown for AX and brown-and-white for AXPare compatible with single or dual-connection masks, offering versatile and comprehensive protection.

3. Chlorine-bromomethane: A solvent and chemical intermediate in laboratories, used in pharmaceutical and chemical industries.
4. Acetaldehyde: Employed in the production of acetic acid, perfumes, and dyes, within food, cosmetic, and industrial sectors.
5. Ethyl bromide: Utilized as an alkylating agent in organic synthesis for chemical and pharmaceutical industries.
6. Butane: Used as fuel for lighters, gas cylinders, and propellant in aerosols, within energy and cosmetic sectors.
7. Ethyl chloride: Used in the production of resins and plastics
   within polymer and coatings industries.
8. Chloroform: A solvent and chemical intermediate in pharmaceutical and chemical industries.
9. Allyl chloride: A raw material for producing pesticides and resins in agriculture and manufacturing.
10. Vinyl chloride: A monomer for PVC production used in construction and building industries.
11. Difluoro-dibromomethane: A refrigerant and extinguishing agent used in refrigeration and firefighting.
12. Ethanol and Isopropanol: Volatile organic solvents common in laboratories and manufacturing plants.
13. Ethyl ether: A chemical solvent and anesthetic used in medicine and research.
14. Ethylene oxide: A sterilizer for medical equipment and disinfectant used in healthcare and industrial sectors.
15. Formaldehyde: A chemical used in the production of resins, adhesives, and insulating foams, as well as a disinfectant and preservative in medical and cosmetic fields. Common in wood, textile, and pharmaceutical industries.
16. Furan: A chemical intermediate in resin and drug production for chemical and pharmaceutical sectors.
17. Isobutane: A propellant in aerosols and a fuel used in cosmetic and refrigeration industries.
18. Methanol: A solvent, alternative fuel, and raw material for formaldehyde production, present in chemical and fuel industries.
19. Propylene imine: Used in the production of adhesives and sealants in construction and manufacturing..

AXP filters additionally protect against:

1. Acetone: versatile solvent used in chemical, cosmetic, pharmaceutical, and manufacturing industries to dissolve resins, oils, and fats, as well as to produce plastics and pharmaceuticals. Also used in the production of paints, solvents, and adhesives.
2. Acrolein: An intermediate in the production of acrylates and resins for plastics.
3. Dichloroethylene: A solvent for degreasing metals and producing adhesives, coatings, and plasticizers in industrial applications.

AXP filters for respiratory protection also are effective against toxic particulates like fine dust and chemical mists.

 

Sectors where to use AX and AXP filters for respiratory protection

AX and AXP filters for respiratory protection are recommended in environments where exposure to hazardous organic vapors or particulates is a risk.

Key industries using these filters include:

1. Chemical and Petrochemical Industry: Protection against substances like chlorine, acrolein, formaldehyde, and methanolin production and synthesis plants.
2. Automotive Sector: Used in the manufacturing of plastic components and adhesives that emit chemicals like dichloroethylene andacetone.
3. Plastics and Paint Industry: Shield workers from vapors released by solutions like ethylene chloride and chloroform during the production of plastics, paints, and coatings.
4. Pharmaceutical Industry: Protection against gases and vapors from substances like ether, methyl ethyl ether, and acetic acidcommonly used as solvents or reagents.
5. Textile Industry: Filters protect from vapors including acetone, ether, and ethyl chlorideemitted during the processing of synthetic and natural materials.
6. Metalworking and welding: Essential for workers handling acetone and methanol for metal cleaning and treatment, as well as toxic welding gases.
7. Research and Laboratories: Used in labs where hazardous chemicals like chloroform and vinyl chloride are handled.

Using AX and AXP filters is critical for ensuring worker safety and preventing acute or chronic inhalation risks.

 

Certifications and Compliance

To ensure maximum protection, AX and AXP filters for respiratory protection must meet strict standards. These devices comply with European regulation EN 14387:2004+A1:2008, certifying their effectiveness against gases, specific vapors, and combinations with particulates.

The EN certification guarantees thorough quality testing and suitability for use in complex industrial environments. Choosing PPE compliant with regulations not only fulfills legal obligations but also ensures health and safety.

 

Conclusion

Investing in respiratory protection is crucial for a healthy and productive work environment.
AX and AXP filters provide a versatile and reliable solution for workers exposed to organic vapors and hazardous particulates.
