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 £0.013 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
