VA-M40MKII mobile warm air heater for tent heating.

Category: Tag:


The VA-M40MKII Warm Air Heater is a transportable unit, developed primarily to provide heating in tents or temporary, transportable buildings. The unit is designed to be placed outside the tent, with supply and return air ducted to the tent.

The VA-M40MKII heater operates on the in-direct fired (clean air) principle thus insuring that no combustion products or fumes are introduced into the occupied spaces. The forced air system provides for the most rapid warm-up capability.

The VA-M40MKII heater is essentially self-contained, requiring only a source of external electric power and fuel. The unit will operate effectively on almost all diesel fuels. Appropriate fuels are supplied by the fuel hose assembly which may be connected to external jerry cans or drums.
