A3AXP3 Combined Filter (RD40x1/7 DIN Thread)

The A3AXP3 combined filter with RD40x1/7 DIN thread is designed for demanding Australian construction, mining and manufacturing environments where mixed airborne hazards may be present. This multi-protection filter combines high-capacity gas/vapour sorbent media with P3 particulate filtration to support safer breathing performance and improved workforce productivity across extended tasks.

Rated for A, AX and P protection classes, it helps protect against organic gases and vapours with boiling points above 65 °C (A) and below 65 °C (AX), plus solid and liquid aerosols (P) such as dust, smoke, fibres and other fine particulates. Typical contaminants include solvents and fuels used on sites and in workshops (e.g. toluene, styrene, petrol, acetone and methanol), making it a practical choice for mixed-exposure work areas and changeable conditions.

Built with a robust ABS housing and a microfiber glass media plus activated charcoal filtration system, this filter is engineered for industrial reliability while maintaining manageable weight for reduced user fatigue. The RD40x1/7 thread conforms to EN 148-1 for secure connection to compatible DIN-thread respiratory equipment, supporting standardisation across fleets and simplifying procurement.

Compliance is aligned to internationally recognised performance requirements for powered and non-powered respiratory protective devices, including EN 12941 (TH3) and EN 12942 (TM3). Suitable operating conditions are 0 °C to +60 °C (20–95% RH), supporting use in varied Australian site climates. Supplied as a single unit, it offers straightforward inventory control and cost-efficient replacement scheduling.
