Dispelair® products for the wet end are designed to work as effective deaerators in the paper & board manufacturing process. The appropriate product choice is largely determined by the temperature, chemical nature of the furnish and regulatory requirements. We have within our product range deaerators and defoamers that fully meet the requirements of BfR, FDA and GB 9685. Effective deaeration can lead to process benefits which include increases in production, drainage and improved web strength. Dispelair® products assist in the clean running of the paper machine and do not contribute to pitch accumulation.
