Medo LA80 Air Pump. Medo pumps are uniquely different to other blowers as they dont use diaphragms. Instead, they use engineered & machined, PTFE lined, metal-alloy Linear-shuttles at the heart of their pumps to generate the air-flow. This technology results in higher performance, quieter running & up to double the lifetime when compared to diaphragm blowers.
