High-Performance PAPR

Rugged powered respiratory protection, engineered for long-duration wear. The ILC Dover Sentinel XL® HP (often referred to as “Sentinel HP”) is a NIOSH-approved powered air-purifying respirator (PAPR) system designed to provide healthcare professionals and lab workers with high-performance respiratory protection in infectious disease environments.

With multiple head cover and full hood options, the Sentinel XL HP platform helps organisations standardise a single blower system while tailoring the wearer interface and filters to match the task, hazard profile, and operational protocols.

Why teams choose Sentinel XL® HP

• Designed for infectious disease environments: built to support healthcare and laboratory use cases where enhanced respiratory protection is required.
• Flexible protection configurations: choose head covers or full hoods to match your APF requirements and operational needs.
• Single blower platform: the Sentinel XL blower platform is positioned to support infectious disease and (with conversion kits) CBRN/decon applications, helping simplify inventory.
• Multi-function filter compatibility: accommodates HEPA and OV/AG/HE filter options for variable requirements.
• Operational ergonomics: Quick-Loc™ attachment system and adjustable, cleanable waist belt support repeatable donning and extended wear.

Protection configurations (head covers & hoods)

• Head cover configuration (APF 25): manufacturer states head covers offer an Assigned Protection Factor (APF) of 25 and can accommodate stethoscopes.
• Full hood configurations (APF 1,000): manufacturer states full hood options can deliver an APF of 1,000 for higher protection requirements.
• Example hood options (manufacturer part numbers):
  • White Head Cover: S-4001
  • BioShield™ Full Hood: S-2028
  • Clear Hood: S-3101 (includes wide field-of-view design)

Conversion capability

The manufacturer notes the Sentinel HP can be converted to support hospital decon/CBRN operations by purchasing a CBRN conversion kit (conversion kits available). Ensure selection and deployment are aligned to your organisation’s risk assessment, training program, and regulatory requirements.

Frequently asked questions

Does a loose-fitting PAPR require fit testing?

The manufacturer describes Sentinel XL HP head covers/hoods as a loose-fitting PAPR configuration that does not require fit testing.

What level of protection does the system provide?

Manufacturer-stated performance varies by configuration (for example, APF 25 for head covers and APF 1,000 for full hoods). Select the configuration that aligns with your hazard assessment and procedures.

How long does a battery last?

Manufacturer-stated nominal runtimes include approximately 8 hours for NiMH rechargeable packs and 10 hours for alkaline packs (example configuration), depending on the specific battery option and usage conditions.

Can we standardise one platform across multiple scenarios?

The Sentinel XL blower platform is positioned to support multiple applications by changing head covers/hoods, filters, and (where required) conversion kits—helping simplify inventory and training.
