Especially in enclosed spaces and dusty working environments, they ensure a clean atmosphere and improved visibility of the workpiece surfaces – a crucial factor for the quality of the surface coating. ✅ Environmentally friendly & efficient: The environmentally friendly filter systems reliably capture dust particles and return cleaned air to the environment. Our jet-pulse filters are among the most widely used systems for the extraction of dry particles and for process air filtration. ✅ Maximum efficiency with low maintenance: The jet-pulse system is designed for maximum performance while minimizing maintenance time and operating costs. It is used in dust extraction systems, pneumatic conveying systems and for the removal of health-endangering substances from the air. ✅ Modularly expandable & recyclable: For even higher separation performance, the jet-pulse filter can be combined with bag filters or cartridge filters as well as a mono-cyclone. In systems with recovery systems – e.g. for the recycling of powder coatings – mono- or multi-cyclones can be used. ✅ Flexible design: The systems consist of integrated modules and can be adapted in size, material and filter type. Depending on the type of dust and the application, a choice can be made between cartridge or bag filters. Kledpfx Asggyhijmrou ✅ Powerful & sustainable: PROTON dust filter systems impress with their high filtration performance and contribute significantly to improving the quality of work as well as protecting the environment and employees. ⭐Note on prices:⭐ The stated prices do not include a mono-cyclone and apply exclusively to the jet-pulse filter unit. The control cabinet is also not included in the scope of supply. For prices on additional components such as a control cabinet or mono-cyclone, please contact our sales department. ⭐Follow us for new campaigns⭐ ☀️ 2 YEAR WARRANTY ☀️
