Clack pouring funnel (opening: 2.5", 4", 6") (for most filter media: quartz sand, activated carbon, resin, manganese sand, fine sand, gravel)
Clack美國 funnel, imported from Wisconsin, is specially designed for users in the 美國 market. Clack's technical department specializes in the sliding characteristics of various filter media, and designs the optimal funnel angle, wire shape, and engraving height to guide the filter media smoothly into the barrel. The neck of the funnel has a carefully designed exhaust port, which allows the air trapped in the FRP pressure barrel to be discharged naturally when the filter material is poured. Clack actually observed ergonomics and designed an oval opening design to provide an extra-wide pouring area, while the handle molded design increases the convenience of force.
