Page 3: Operating Principle And Use Of Sf2300 Air Heaters
Operating Principle and Use of SF2300 Air Heaters The SF2300 air heaters are designed to be used as auxiliary heaters for trucks, RVs, boats, construction and farm equipment. The heaters will provide heat and keep a comfortable air temperature for the operator (driver) cab, small RV, passenger vans, mini buses, boats, etc for a fraction of the cost in comparison to engine idling. -
