Product Description
The L.B. White Tradesman K400 is a high-capacity, portable forced-air heater delivering 400,000 BTU/hr of powerful heat for large construction sites, industrial buildings, warehouses, agricultural facilities, and any application requiring substantial temporary heating. Designed for durability and efficiency, the K400 uses kerosene or approved multi-fuel blends and includes a large onboard fuel tank for extended runtime.
