Does anyone know how many amps an Fantastic Fan pulls?

I have 2 fantastic fans from 2000.

All measurements with clamp on ammeter at the converter wire/fuse for each fan....converter was on with 1 new AGM 12 volt battery fully charged.

Front bedroom fan with temp control, bulb style. 4 amp fuse, 25 watt motor/5000RST
Low 0.8 amps 5.4 mph 509 ft/min
Med 1.3 amps. 6.6 mph 605 ft/min
High 1.8 amps 7.5 mph 700 ft/min


Rear fan no temp ctrl, 6 amp fuse, 36 watt motor/400R
Low 0.8 amps 6.1 mph 561 ft/min
Med 1.1 amps 7.6 mph 700 ft/min
High 1.5 amps 8.8 mph. 826 ft/min

I have no idea why the lower wattage motor is pulling more amps except that voltage drop must be in play since the rear fan is only a few feet from converter and the bedroom is a 20 foot wire run.

Edited after Mex made me run to the store to get a new 2032 battery for my wind speed meter that's been sitting in my toolbox for a few years. TP test is too subjective....single or double ply?

I suspect some of the differing numbers are being caused by the different motors used in FF's.
The older, BLACK motors use less current and are more quiet.
The newer, GOLD iridite pancake style motors have a hum to them and use more current. (Thanks to Dometic for buying a great company and cutting corners)
I have one of each and a built in ammeter so I'm in a unique position to measure these right now.
Here are the numbers:

Old black motor style:
1. 1.3A
2. 1.5A
3. 2.0A

New gold motor style (Post Dometic purchase):
1. 1.4A
2. 2.1A
3. 3.1A

Current measurements +/- .1A
Batteries (2X6V) at 12.7VDC (converter off)

I would like to know about running this thru the night on my two 6 volt batteries running as a 12 volt with a total of 432 amp hours.

Must be a typo for 232 AH, which is what two Interstate type 6s would be before they switched to Trojan 225s recently.

Our 2002 year? fan draws 1.2, 1.7, and 2.4 amps as seen on Trimetric monitor

300 milli amp difference from the Trimetric but still no where near that junk you are running.

Just curious - how do you know what "junk" I'm "running". :h

That aside - a fan rated @ 36 watts by the manufacturer running on 12 vdc by the math will pull ~ 3 amps, just what they claim and the reason this fan is fitted with a 4 amp fuse. Oh wait a minute, I forgot - the manufacturer is "lying". :R

Yeah, right. :W

If any of my fans were pulling 3 amps I'd throw them in the trash. My 120 volt residential ceiling fan pulls 3.7 amps DC on high. Even if the inverter idle of .5 is included it's at 4.2 and it's a wind storm.

I measured all the loads on my previous 2009 trailer with a Fantastic Fan. Got 1.0, 1.4 and 1.75A at the 3 speeds.

Quite a bit lower than the manufacturer reports.

Thank you for the replies. We are headed to dry camp at Itasca State park in MN for 6 days. I have an onboard genny to top up the batteries when needed. Cant wait until I get solar installed.

Heck yeah!! The headwaters. I was there 2 years ago. I got up early and it was a chilly morning but I rode my bicycle down that beautiful pathway and found the headwaters deserted and got perfect pictures. DW wanted to go take pics later and it was packed. Enjoy.

Here are the numbers for MY supposedly 13 speed Fantastic. I dont know the model number and serial number and dont care.

It was checked with a fuse buddy. If you dont believe it or dont like the fuse buddy results go test your own stuff with your own meter.
Speeds:

Off
1. .0
2. .1
3. .2
4. .2
5. .3
6. .3
7. .5
8. .9
9. .85
10. 1.05
11. 1.3

Fantastic claim .2 to 1.9 amp draw. They lied it's too low. Time for lawsuit for them or fuse buddy but someone is in for hell I'm right and I'm not going to put up with this lying.

I only know one thing, that is that on low they don't draw enuff to even think about it. And yes, nothing but dry camping.

And my 2 6v batteries have only 230 amp hrs, not 430. Those must be some hurcules 6'ers !
