The Pre-filter Keeper for DIN Thread Filters is a purpose-built accessory designed to securely retain a pre-filter on compatible DIN thread particulate or combination filters used with tight-fitting respiratory protection. In high-dust Australian worksites, pre-filters can reduce premature loading of the main filter media, helping extend service life and maintain stable breathing resistance. This keeper ensures the pre-filter stays correctly seated during movement, vibration and repeated handling—supporting consistent protection and minimising stoppages for rework or re-fitting.
Built for demanding construction, mining and manufacturing environments, the keeper improves day-to-day usability by simplifying filter changes and reducing the likelihood of misalignment that can compromise performance. For supervisors and procurement teams, it’s a low-cost component that can help protect higher-value filters from excessive particulate contamination, supporting better stock efficiency and reduced consumable spend over time.
Use where airborne dust and particulate exposure is common—cutting, grinding, drilling, blasting, bagging, sweeping and general maintenance. The keeper is intended to be used only with compatible DIN-thread filter systems and pre-filters, and should be inspected regularly for damage or deformation as part of your respiratory protection maintenance program.
Note: Technical specifications (materials, compatibility list, and any certification details) are not available from the supplied documentation. Please request confirmation from the manufacturer to ensure suitability for your specific respirator and filter configuration.
