Particulate Filter

P3R is the dependable choice for dusts, fibres, mists, fumes and radioactive particulates, delivering up to 99.999% filtration efficiency with a compact 40 mm canister that’s easy to carry and easy to breathe through across long shifts.

Paired with a certified half‑mask, full‑face mask or PAPR, P3R protects against a wide range of solid and liquid particles without the drag of high breathing resistance. It’s dolomite‑tested to prove resistance to clogging and housed in hard, shock‑resistant plastic that tolerates the knocks of operational use. A long 20‑year shelf life supports fleet sustainment and forward staging.

Why teams choose P3R

• Very low resistance: < 70 Pa @ 30 L/min; < 230 Pa @ 95 L/min — easier breathing, clearer comms.
• High‑efficiency filtration (P3 class, up to 99.999%).
• Rugged housing survives rough handling and transport.
• 20‑year shelf life for reduced whole‑of‑life cost.

Selection & compatibility

Use P3R when particulate hazards dominate (construction dust, wildfire ash, biological aerosols, radioactive particles). For gases/vapours, step up to multi‑threat CBRN canisters. Compatible with HM/FFM/PAPR platforms via the 40 mm thread.

Typical uses

Demolition and decon, bio‑aerosol response, wildfire smoke and ash, dusty vehicle recoveries, training ranges.

Care & compliance

Keep sealed in original packaging until issue; observe storage limits; match canister type to risk assessment and platform approvals.

FAQs

Does P3R stop vapours?

No, it’s a particulate filter; combine with the correct gas canister if vapours are present.

Fit testing needed?

Yes for tight‑fitting HM/FFM.

Can I run it on a PAPR?

Yes, compatible with approved PAPR platforms.
