The R-4013 is a compact, versatile and high-output heater/defroster. The blower housing can be rotated 360 degrees in four separate positions so heat and defrost outlets are where you need them. Like other Red Dot heaters, the tube and fin coil design allows mounting in any position – bulkhead, firewall or floor. The compact design often allows underdash or other compartment installation. Along with a two-speed motor, a diversion door can be manually or cable-operated to control defrost and heat output. An optional adapter to the heat outlet turns the R-4013 into a duo defroster or multi-compartment heater.
