Performance in the field is influenced by chemical concentration, temperature, vacuum, pressure and other application variables. Therefore, all factors must be considered before purchasing your flexible ducting. We have put together a few guides to aid with your decision. Suitability for a particular application may only be determined under actual service conditions and sample trials are recommended to assure satisfactory services.
Please take a look at our technical data tables. Follow the links below.
