Generator Size

[Auto concepts]

I am looking at getting a Yamaha EF2400 ISHC Generator...but am having problems trying to figure out if it will be big enough to run the equipment I have. I have a Mytee Lite II, a CamSpray 1500A Electric Pressure Washer and a 1 HP air compressor...I just need to run one at a time. I was wondering if anyone has any experience using this equipment on the Yamaha generator or any other generator. And if you have, what size generator are you using? From what I have found...I am right on the line of either working, or not having enough watts. I just want to make sure I get the right size generator and stay on budget. Any info is appreciated!

I run a 3000 Honda EU unit. No problems. If you run only one unit...just do the math on the amps and watts (it's been a while so this might be incorrect). You need to find the surge useage and make sure you are covered. I run a steamer, or extractor, but really only try to do full details in a shop with electricity.

Identify the tool requirements. Most air powered tools will have a measuring unit indicating minimum air pressure required to operate. Most common is the SCFM (Standard Cubic Feet per Minute). Ensure your air compressor is capable of providing this value

Tool air requirements SCFM @ 90 PSI



• 6-inch pneumatic palm Sander / Polisher - 15-20.0

• 3- inch pneumatic palm Sander / Polisher – 4- 6.0

• Impact Wrench - 2.5-10.0

• Mini Die Grinder 4-6.0

• Grease Gun - 4.0

• Touch-up HVLP air spray gun 4 – 6.0

• Air Foamer HP Foam Gun – 5.0

• Tornador Car Cleaning Gun – 5.0



Add the CFM of the tools that will be used at the same time plus 10%, add this number to the total CFM required. The number you come up with will be the highest rating of air compressor you should be looking for. This CFM rating will allow you to run your tools without over-taxing the compressor.



Power Requirements



Identify the power requirements. Air compressors come in either 120/220Volts, 120V compressors are suited to home-improvement and small projects while 220v means it are an industrial compressor. 120v/220v air compressors will need a 15AMP dedicated circuit to power them. This means you cannot use your washing machine and the compressor in the same circuit

The Yamaha 2400 is rated at 16.8 amps constant and 20 amps max .It has been tested to hold 25 amps for 10 sec. The mytee lite 2 according to tech support at mytee will run on a 15 amp circuit . He said it can pull 16 to 18 amps max.the motor on the mytee is single 2 stage. The cam spray 1500 has a induction motor which is known to pull more amps at start up then drop down . They rate the camspray at 18 amps . i don't know if that's running amps or starting amperage. and the air compressor is 1 hp running . Thats all the info i have on it. it is a craftsman.I know the yamaha will run a 13500 btu air unit with no problem . My end goal is to get the correct gen for my needs but if i could save 700 dollars i sure have other places i could use the cash.Again thanks for any info guys.

Generator



Add up the start-up amps of any motors that need to run at the same time (i.e. power washer and tank supply water pump) and then multiply this by the voltage used (115) this will give you the watts output you require from a generator. A good rule of thumb is to choose a generator that supplies more power than you actually need.

In these days of advanced fuel-injection systems it's a surprise to come across a choke. This is activated by turning the ignition switch one notch further to add extra fuel to the mix to aid start-up. You have to remember to switch it back once the engine is running.



There's also an Ecothrottle setting, which runs the generator only as fast as the electrical load demands in order to reduce fuel consumption and prolong engine life
