If the fluid level in the tank varies considerably, the lowest fluid level should always be used. For more information on standard band lengths, please go to the unique skimmer page.

Eg. on using the formula:
Using the formula for a vat of 500 mm in height the result will show 1140. However 1140 mm. is not a standard length. In this case a shorter (closest to result) standard length should be selected (in this case 1000 mm.). This is a general rule, but there can be exceptions. If the bottom roll is not covered in fluid a longer length must be selected. Of course we can also make the exact band length for your needs. In this case please contact us for inquiry.

This formula is a general guidance. For special jobs, please consult us before ordering the band.
