A1 P3 Combined Filter RD40x1/7 DIN Thread

The A1 P3 combined filter with RD40x1/7 DIN thread is engineered for industrial respiratory protection where both organic vapours and hazardous particulates are present. Designed for compatibility with RD40x1/7 (EN 148-1) threaded respirators and powered air/powered hood systems that accept DIN filters, this unit helps standardise consumables across sites—supporting productivity and simplified procurement.

The A1 gas element protects against organic gases and vapours with a boiling point above 65 °C (e.g. common solvents and fuel-related vapours). The P3 particulate element provides high-efficiency filtration for solid and liquid aerosols such as dust, smoke, fibres and other fine airborne contaminants commonly encountered in construction, mining maintenance, fabrication, and manufacturing processes. The filter media combines microfiber glass filtration with activated charcoal to deliver balanced performance in mixed-exposure environments.

Built with a robust ABS housing for jobsite durability, this filter is suitable for demanding Australian worksites where reliability and uptime matter. It is tested to stringent European respiratory standards for powered and non-powered applications (as applicable), including aerosol penetration limits and gas capacity testing, helping safety managers meet compliance requirements while controlling ongoing consumable costs.

• Combined A1 + P3 protection for mixed vapour/particulate tasks
• RD40x1/7 DIN thread (EN 148-1) for broad equipment compatibility
• High filtration performance for fine dust and aerosols (P3)
