The NR series is particularly suitable for the suction and transport of even very dusty air, sawdust, various shavings, granular materials, with the exception of filamentary materials.
The NR series has high flow rates and medium pressures, statically and dynamically balanced steel backward blade impeller. Fluid temperatures up to 60 ° C in standard execution; special executions for higher temperatures.
■ ATEX non-sparking version: shims on non-rotating parts potentially in contact with the fan in non-ferrous material.
■ Anticorrosive execution of paint choirs or special materials.
■ High temperatures with cooling fan up to 300 ° C, special executions on request for temperatures up to 450 ° C.
Direct coupling. Impeller mounted directly on the motor shaft. Flanged motor and fan without chair. Maximum operating temperature in standard execution: 60 ° C. In special execution: 150 °
