The Grundfos Conlift1 LS (98452219) is a compact, automatic condensate removal pump for condensing boilers, air-conditioning units, refrigeration systems and dehumidifiers. It is the cost-effective entry-level model in the trusted Grundfos Conlift range.
It is used where condensate is collected below drain level, or where it cannot reach a drain by natural fall, for example a boiler in a basement or an AC unit far from a waste pipe. The pump collects the condensate in its tank and automatically pumps it away when the tank fills, so no manual operation is needed.

- Pre-fitted non-return valve with bayonet fitting
