Chemical Filler Bulk Hakadon FillerAlso known as Tti-Pac, it is commonly used in air purification devices domestically, hence the colloquial names of Filter Ball or Environmental Protection Filter Ball. The characteristic of the filling material is that it consists of many bar-like branches interconnected to form a hollow sphere, with no large surface area. This filling material boasts a high porosity and a large free cross-sectional area in all directions, with minimal anisotropy.

Chemical Filler Bulk Halden FillerDue to its composition of many grid-like branch rod combinations, it provides numerous flowing convergence and divergence edges for downstream liquids, effectively wetting the packing surface and forming numerous droplets. This promotes the surface renewal of the liquid, benefiting the mass transfer between gas and liquid phases. It is widely used in gas absorption and purification, as well as in dehumidifiers.
