⻬ 120 and 240 Vac
Finned tubular air heating elements are constructed like basic tubular elements with the addition of continuous
spiral fins, 4-5 per inch permanently furnace brazed to the sheath. Fins greatly increase surface area and permit
faster heat transfer to air, resulting in lower surface element temperatures.
