DynaVap CCD titanium screens are precision-made diffusers that filter fine particles without restricting airflow. Titanium provides high temperature stability and increased durability for daily use. The sales unit includes three screens, allowing months of use. The product is compatible with DynaVap titanium and stainless steel tips. For cleaning we do not recommend using alcohol or other flammable liquids. Although alcohol does not necessarily damage the components, we advise against prolonged soaking.
