F a n t y p e s J K - 3 K - J K - 7 5 K Section: 2 Page: 1/6 Revised: 1..25 The indirect drive centrifugal fan types JK-3K - JK-75K are designed for material handling. M N Equipped with self-cleaning impellers with backward-inclined blades and aerodynamic intake. The impellers are statically and dynamically L balanced. F D The pulleys are shaft-mounted with taperlock bushing, allowing easy replacement for changed fan speed. K Max. operating temperature: 6 C With cooling wings: Up to 2 C Number of blades are reduced by 2 for paper impeller. Available in anti-spark version with stainless steel inlet and explosionproof (Eex) motor. J I Dimensions (D) for the inlet are external. Supplied smooth. H Belt drive is anti-static.
