Keeps the installation as simple as possible.

Changing to a 12V motor is the best solution. We have them today and they are the proper solution to get a stable, lower voltage.īeware, several of those resistors sold to reduce 12 to 6V seems to be called regulators despite only being a resistor.īut, as others have said. Not traditional, we didn't have that when the declaration of independence was written, blah blah blah. What you want in cases like that is a voltage REGULATOR, electronics that actively regulate the voltage. For electric motors it is not, especially not when they have multiple speeds to choose between. Using resistors to reduce voltage is a relatively bad idea, UNLESS the current draw is quite stable. So, when the fan is supposed to start the motor draws LOTS of current it will get a very low voltage, perhaps not even enough to start, it it's running at high speed the current draw may be low and the voltage reduction not enough. Find low everyday prices and buy online for delivery or in-store pick-up. The 12 Volt fan is for use with the Excel AC/DC or Excel NE when there is down-draft present. bus /Car 6 inches 12 Volt DC Oscillating Automotive Desk Fan (Multicolor). At high current the voltage will be reduced a lot, at low current barely at all. Fans Works Fabulously in Cabins and Office Spaces. Yes, this will reduce the voltage, but by how much depends on the current draw. The metal fan blade is more durable, the wide blade surface increases the air supply volume, and the air volume is 54m³/min. Attach the suction cup of the fan holder to the smooth clean surface that is the most suitable location for your daily use. Many of these are simply a resistor to put in series. The homdec 12 volt fan is more reliable and not easily damaged. That is the only thing that allows the underdash rheostat switch to not overheat on any speed.īest permanent solution, if you have only one blower motor, NAPA sells a generic barrel shaped 12v heater motor with 1/4' shaft that is the correct diameter for most vintage heaters, somebody listed the NAPA number on here in the past. I ended up using a vintage, very large (huge) ceramic resistor specifically made for such conversions, made maybe in the late 50s. Mine is my primary year round car, so I'm posting 'heavy use' facts. I run an earlier vintage Olds heater with stock main motor and a mini motor for the defroster, both are 6v. Leave it on low too long, and it may even ignite the plastic. On Medium speed even hotter, and on Low speed where it be most of the time, the switch will get so hot that it melts the colored insulation on crimp connectors. axial fans, centrifugal blowers and 12V accessories since 1989. That won't work very well at all, as on HI, the rheostat will still get hot. facture of high quality electric fans and blowers for all types.

Next possible thing that may be mentioned is a vintage underdash rheostat heater switch with 3 speeds. Runtz is for low milliamp draw, like gauges, it won't work on blower motors. Our range of vehicle cooling fans attach with a bracket or clip and plug into the cigarette lighter socket.
