A liquid-collection canister includes a liquid collection chamber defined by at least one wall and a first and second gas-communication pathway formed within the at least one wall. A first aperture is positioned between the first gas-communication pathway and the liquid collection chamber to allow gaseous communication between the liquid collection chamber and the first gas-communication pathway. A second aperture is positioned between the second gas-communication pathway and the liquid collection chamber to allow gaseous communication between the liquid collection chamber and the second gas-communication pathway. A first and a second liquid-air separator are positioned over the first aperture and the second aperture, respectively, to substantially prevent liquid passing through the first and second apertures.一種液體收集罐，其包含由至少一壁界定之一液體收集腔；及形成於該至少一壁內之一第一及第二氣體連通通道。一第一孔隙係定位於該第一氣體連通通道與該液體收集腔之間以容許該液體收集腔與該第一氣體連通通道之間之氣體連通。一第二孔隙係定位於該第二氣體連通通道與該液體收集腔之間以容許該液體收集腔與該第二氣體連通通道之間之氣體連通。一第一及一第二液體空氣分離片係分別定位於該第一孔隙及該第二孔隙上以實質上防止液體通過該等第一及第二孔隙。
