izac700 is a drip coffee maker which infuses coffee with dripping cold water. It can extract the less bitter taste of original coffee and has the mild and soft flavor. The extracted coffee can be stored for a long time by maturing at a low temperature. Other products have the unequal quality of extracted coffee due to irregular interval of drips caused by difference of water pressure. However, izac700 has patented intermediate canteens which keep the constant water pressure and regular dripping intervals until the water is used up with a single adjustment of the valve.
