12x40 Carbon Spec Sheet

Filtration Media
	ProActive™ 12x40 Carbon

ProActive 12 x 40 Granular Activated Carbon is made from a superior quality anthracite and non-viscous coal. It is recommended for residential applications, this carbon is almost twice as effective at chlorine removal than our 8 x 30 grade. ProActive 12 x 40 Carbon has a superior iodine rating of 1000 minimum and it is great for organics too.
FEATURES • High adsorption capacity and efficiency. • Super durability that stands up well to backwash. • Low fines, no floats, rinses fast.

Warning For safety and handling purposes, we recommend appropriate protective measures when entering a wet vessel containing granular activated carbon, because wet activated carbon depletes oxygen from air and therefore, dangerously low levels of oxygen may be encountered. In such a case, the oxygen level inside the vessel shall be determined before entering and appropriate protective equipment should be worn when entering, or leave the vessel open until the oxygen level in the vessel is normal.
