Finnleo IS401 IR-only (175-310 cu ft) Infrared System

Finnleo Infrared (IR) Heating System — IS401

Finnleo's IS401 Infrared Heating System lets you transform any permanently installed residential sauna into a dual-mode wellness sanctuary. By adding a low-EMR infrared emitter panel alongside your existing traditional heater, you gain the freedom to choose between a classic high-heat Finnish session and a gentle, lower-temperature infrared session — all in the same room. Infrared heat radiates directly into the body rather than simply warming the surrounding air, producing deep perspiration at a more comfortable ambient temperature that many bathers find easier to tolerate for longer periods. The IS401 kit includes one mid-size infrared emitter panel and a contactor box, sized for rooms between 175 and 310 cubic feet, ready to integrate cleanly into your sauna's existing tongue-and-groove walls.
