Respirators Reusable Respirators Half Face Respirators
4000 series maintenance-free half masks are simple and ready to use respirators with an integrated cartridge and filters. They provide protection against a range of organic gases and vapours, also combination particulate hazards.

  • Newly enhanced valve assembly reduces exhalation breathing resistance for improved breathing comfort
  • Lightweight, well balanced, low profile design
  • Integrated cartridge and filters are ready to use and maintenance-free
  • Adjustable head cradle and easy to fasten neck straps
  • Centrally positioned exhalation valve reduces heat and moisture build up
  • Includes a resealable bag for hygienic storage and transportation

The lightweight, well balanced design features a centrally positioned exhalation valve that helps reduce heat and moisture build up, increasing comfort in hot and humid conditions.

The integrated cartridge and filters are maintenance-free. Simply use them until the change-out schedule indicates a replacement is needed or when the filters are full, and then discard. Masks will provide up to 40 hours of use when stored in the resealable bag provided. An adjustable head cradle helps fit to a broad range of head shapes and sizes, and the neck straps are easy to fasten. The low profile design won’t hinder peripheral vision, and the two large, bonded-carbon filters ensure low breathing resistance.

FFA1P2 RD filter/cartridge protects against organic vapours, with a boiling point greater than 65 °C, up to 10× Workplace Exposure Limit (WEL) or 1000 ppm (whichever is lower), and 10× WEL for particulates.
FFA2P3 RD filter/cartridge protects against organic vapours with a boiling point greater than 65 °C, up to 10× Workplace Exposure Limit (WEL) or 5000 ppm (whichever is lower), and 20× WEL for particulates.
FFABE1P3 RD filter/cartridge provides protection against organic vapours with a boiling point greater than 65 °C, inorganic vapours, and acid gases up to 10× Workplace Exposure Limit (WEL) or 1000 ppm (whichever is lower), and 20× WEL for particulates.
FFABEK1P3 RD filter/cartridge provides protection against organic vapours with a boiling point greater than 65 °C, inorganic and acid gases and ammonia up to 10×Workplace Exposure Limit (WEL) or 1000 ppm (whichever is lower), and 20×WEL for particulates.
