A2B2E2 P3 Combined Filter – RD40x1/7″ DIN Thread

This A2B2E2 P3 combined filter with RD40x1/7″ (DIN) thread is designed for demanding Australian worksites where mixed gas/vapour exposure and hazardous particulates can occur at the same time. It provides broad-spectrum protection against organic vapours (boiling point >65°C), inorganic gases, acid gases, and P3-grade particulate aerosols such as dust, smoke and fibres—helping reduce respiratory risk without forcing workers to swap filters between tasks.

Built for industrial reliability, the filter uses a robust ABS housing with activated charcoal and microfiber glass media to support consistent performance in construction, mining and manufacturing environments. It also includes tested protection against ozone at concentrations below 20 mg/m³, adding capability for specific processes where ozone may be present.

The RD40x1/7″ thread (EN 148-1) suits compatible DIN-thread respirators and powered air systems, making it a practical option for standardising consumables across crews and sites. With defined breathing resistance and stringent aerosol penetration limits, it supports worker comfort and productivity—helping reduce fatigue during long shifts while maintaining compliance obligations.

Operating conditions cover -10°C to +55°C with up to 95% RH, supporting use in varied Australian climates and site conditions. Supplied as a single unit for controlled issue and straightforward stock management.
