Excalibur 1240C-S Granular Activated Carbon

Excalibur 1240C-S is a virgin granular activated carbon produced from coconut shell char under stringent quality control through a high temperature steam activation process with proprietary kiln gases that enhance the natural catalytic capability to a high level. It has a large surface area, high mechanical hardness, excellent pore volume and chemical stability to make it ideal for liquid phase applications that require catalytic properties for optimal performance.

Excels at monochloramine and hydrogen sulfide removal from potable water. California Prop 65 compliant.
