Dewalt f340661 Propane Forced Air Heater 68000 Btu/h

Product Description

The DEWALT f340661 is a cordless-capable propane forced-air heater designed for job sites, remote workspaces, and areas without access to grid power. It delivers variable heat output ranging from 27,000 to 68,000 BTU/h, giving installers and tradespeople precise control over worksite temperature. The unit runs on a standard 20-pound propane tank and is powered by DEWALT 20V MAX or FLEXVOLT batteries, eliminating the need for a dedicated power outlet in the field. A hybrid power option is also built in via a rear-mounted 120V plug connector for use with an extension cord when power is available. Steel construction and a two-piece barrel design support durability and straightforward field maintenance.

This heater is suited for temporary heat applications on construction sites, in unheated garages, warehouses, and other large work areas without permanent HVAC service. With a rated coverage area of up to 1,700 square feet and a runtime of up to 10 hours per propane tank, it handles extended shifts without frequent refueling. The glove-friendly handle supports easy repositioning on the job. A hose and regulator are included in the package. Battery and charger are sold separately. This unit is typically placed by general contractors, electricians, plumbers, and other trades working in cold or unheated structures during construction or renovation phases.
