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 £0.013 Through practical application testing we have been able to compile a table that shows which nozzles perform the same job as an open pipe.
|Open pipe Ø 10 mm (3/8″)||Replaced with SILVENT 705 L|
|Number of hours per year:||Number of hours per year:|
|52 weeks x 5 working days x 8 hours = 2,080 hours||52 weeks x 5 working days x 8 hours = 2,080 hours|
|Cost per hour:||Cost per hour:|
|185 Nm³ x £0.013 = £2.41||95 Nm³ x £0.013 = £1.24|
|Annual operating cost = £5 013||Annual operating cost = £2 579|
