The CDS extractor tube
doesn’t have a
foot valve. When the VARIBOX FC with
a CDS extractor tube is not used for a longer period, the product level in the
CDS extractor tube can gradually drop. When again switching on the pump
there is a change that air will be pumped first.
To ensure the safety of the VARIBOX FC with CDS extractor tube, it is
recommended to replace the CDS extractor tube every year. Inspect the CDS
extractor tube regularly for possible damage and replace if necessary.
Just a little bit of product remains in de VARIBOX FC, because the CDS
extractor tube is placed in the lowest point of the inner container. Because of
the low residue, handling and transporting VARIBOX FC is much safer. After
emptying, approximately 0.1 litres remain in the VARIBOX FC. About 0.4 litres
remain in the CDS extractor tube itself. These quantities are based on water
and will vary per chemical product.
The CDS extractor tube has been developed for use with chemicals. The CDS
extractor tube is resistant to most chemicals, but it is very important to choose
the correct version. If you have specific questions about chemical resistance,
please feel free to contact us.
