The Honeywell 5500 Series elastomeric half-mask air-purifying respirator (APR) facepiece is engineered with an adaptable dual-port interface designed to support modular respiratory protection programs. Molded from grey thermoplastic elastomer (TPE) and fitted with rigid polypropylene cartridge connection ports, the facepiece is supplied without pre-installed cartridges or filters. This design allows procurement teams and safety officers to tailor respiratory setups to plant-specific airborne contaminant profiles, including particulates, gases, vapors, and smoke across chemical, metal processing, oil and gas, manufacturing, and painting operations.
Honeywell North N-Series Cartridge and Filter Compatibility
The dual connection ports feature a direct cartridge-to-facepiece seal geometry that eliminates extra gaskets and simplifies routine maintenance. The facepiece interfaces directly with Honeywell North N-Series threaded filters and chemical cartridges:
- Particulate Filtration: Compatible with Honeywell North N95, R95, and P100 particulate filters for non-oil and oil-based particulate environments.
- Gas and Vapor Protection: Direct mounting compatibility with Honeywell North chemical cartridges, including organic vapor and acid gas formulations.
- Air-Purifying Performance: Achieves an Assigned Protection Factor (APF) of 10 in Air-Purifying Respirator (APR) mode when paired with approved Honeywell North filtration elements in accordance with OSHA standards.
Conversion to PAPR and Supplied Air Systems
To support changing operational hazard levels, the Honeywell 5500 Series can be reconfigured beyond standard negative-pressure ambient air-purifying modes using approved Honeywell conversion attachments:
- Powered Air-Purifying Respirator (PAPR) Systems: Compatible with Honeywell PAPR conversion components to reduce breathing resistance during extended work shifts in non-IDLH environments.
- Continuous Flow Supplied Air Respirator (CF-SAR) Systems: Interoperable with approved Honeywell continuous flow airline conversion systems, enabling connection to external breathable air sources where ambient oxygen levels remain at or above 19.5% by volume.
Integration with Personal Protective Equipment (PPE)
The Honeywell 5500 Series facepiece features a low-profile nose bridge and swept-back lateral cartridge positioning that minimizes physical interference with overhead, ocular, and acoustic protective equipment:
- Protective Eyewear and Face Shields: The contoured nasal profile maintains clearance for prescription safety spectacles, protective safety glasses, chemical splash goggles, and welding or grinding face shields without disturbing the face-to-flange seal.
- Head and Hearing Protection: The woven elastic latex-free nylon head harness and low-profile crown cradle seat beneath standard industrial hard hats and integrate cleanly with helmet-mounted or over-the-head earmuffs.
Standardized Replacement Parts and Multi-Standard Compliance
Full regulatory certification under NIOSH 42 CFR Part 84, European Standard EN 140:1998, and Australian/New Zealand Standard AS/NZS 1716:2012 is maintained only when using authentic Honeywell components. The facepiece utilizes standardized, interchangeable service parts across Small (550030S), Medium (550030M), and Large (550030L) sizes:
- Inhalation Cartridge Connector: Part number 770016
- Inhalation Valve Flap: Part number 770017
- Exhalation Valve Flap: Part number 770018
- Exhalation Valve Seat: Part number 770019
- Exhalation Valve Guard: Part number 770020
- Headband Assembly: Part number 770092
