We have quantified the k-factor for punker series R63D1 in combination with inlet cone ED 11.
The Data Sheet with k-factor for all wheel diameters is available for download on the product page:
What is the k-factor good for?
The pressure tapping inside the inlet cone is used to determine the differential pressure in reference to the fan’s static pressure. By means of the k-factor, which has been determined at the punker lab for all series, the volume flow inside the customer’s system can be calculated and monitored electronically.
