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 1,000 scfm at 70 psi is calculated to the nearest $0.30. Through practical application testing we have been able to compile a table that shows which nozzles perform the same job as an open pipe.

EXAMPLE

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

Scfm cost:

Scfm cost:

109 scfm x 60 min x 2,080 hrs x $ 0.30 / 1,000

55.9 scfm x 60 min x 2,080 hrs x $ 0.30 / 1,000

Annual operating cost = $4,081

Annual operating cost = $2,093
