Product Overview
Ammonia and alkaline gases create challenging working environments in agriculture, refrigeration, and chemical processing. Standard activated carbon struggles with these compounds because they're polar and highly soluble—tending to dissolve into moisture films rather than adsorbing into dry pores.
PFH-K uses a high-strength coal-based or coconut shell carbon substrate combined with advanced production equipment and cutting-edge impregnation technology. Through optimized particle size distribution, the impregnated carbon maximizes adsorption capacity for ammonia and related alkaline derivatives.
