Keller Lufttechnik developed a new generation of filters with the goal of a prolonged filter service life, available in various designs. According to the German company, the new KLR filter, which stands for Keller Long Run, is living up to all expectations.

With the increased surface area, the pressure loss and resulting energy demand consequently decreased by 5 %. Source: Keller Lufttechnik

“We managed to almost double the number of possible compressed air pulses that clean the filter”, informs Manager Frank Keller after extensive testing prior to market launch. The flow-optimized frame construction contributed, with its wide sidebars that protect the filter from direct particle impact and excess wear.

„We are the first manufacturer to guarantee to our customers that the KLR filter elements will achieve a service life of up to 120 000 cleaning intervals without any loss of quality”, he continues.

Another advantage of the novel filter is their reduced energy usage. “We were able to increase the surface area with efficient pleating of the textile filtration materials. This minimizes the pressure differential and consequently the output required to move the air through the filter”, explains Frank Keller. “On average, we realized energy savings of five percent. This value can vary depending on the type of dust and filter plate load.”

KLR filters can be obtained in five different models for instance as antistatic version or with an additional filtration membrane. Customers currently using Keller ProBran or Y-filters can easily switch to the appropriate KLR version during their next filter exchange in order to realize its benefits. “We manufacture these new filters ourselves”, says Frank Keller. “We’ve thereby become independent of suppliers and can adjust our manufacturing schedule promptly to meet the demand for this core component of our dry separation systems.”
