Our highest-performing filter: synthetic of course
The Kalthoff compact filter RELIM VRK ETA expands the successful synthetic compact filter series RELIM VRK with a technological frontrunner. In addition to its consistently high filtration efficiency, the RELIM VRK ETA features a significantly lower differential pressure level. This is achieved through advanced filter media and a specifically optimized compact filter design.
The filter reduces the system’s energy consumption, combining high sustainability standards with low operating costs. The mechanical stability and safety of the synthetic product remain fully preserved.
Features of the RELIM VRK ETA
With the VRK-ETA series, we are introducing two filters with significantly reduced differential pressure in the ePM1 range. The filter classes meet current state-of-the-art requirements, such as VDI 6022-1 and DIN EN 16798-3.
The space-saving compact filter housing is combined with a fully synthetic micro-spunbond to create a robust filter. The medium is inert, meaning it does not provide a breeding ground for microorganisms, and even under mechanical stress during installation and operation, there is no risk of releasing harmful fibers.
The VRK ETA optimizes overall cost efficiency and promotes sustainable practices. In addition to the efficient delivery of clean breathing air, it meets our consistently high standards for a health-safe product that enhances indoor quality of life.
