Open pipe vs. Silvent air nozzle

Compare the major differences between Silvent air nozzles and blowing with an open pipe in the table below, which is based on an eight-hour work day with blowing 5 days per week, year around. The cost of 1 Nm³ at 500 kPa is calculated to the nearest 0.016 €.* Through practical application testing we have been able to compile a table that shows which nozzles perform the same job as an open pipe.
