Power inverter question.?

I searched answers but I am still confused. All I know is 75 watt inverter plugged into cigarette lighter will not run my air compressor. So how many watts do I need? Compressor is 120 volts AC, 3.3. Amps. I saw Black and Decker inverters up to 750 Watts. Do I need that much? Wish I had studied better in physics. TY for any help.

You may not need 750 watts but you will need considerably more than 75 watts. Assuming that your air compressor offers a constant resistive load and 3.3 amps is its current draw, it will take
120 V * 3.3 A = 396 watts

In practice, the current rating will probably be for full load and may or may not represent the actual amount of current your compressor takes. The compressor will approach full load only when its air tank is near full pressure.

Reciprocating compressors also take their current in spurts, taking momentarily more power when the compressor is actually in its compression cycle and less when it is drawing more air into the system. If your compressor doesn’t have a flywheel or some other mechanical means of evening out this load, the current draw could vary wildly while the compressor is in operation.

Finally, the load a compressor puts on the line is usually not purely resistive but has an inductive component to it. This reduces the actual power below the theoretical maximum of Voltage * current but the inverter must still supply the full current. Furthermore, the inductive component may have an effect on the inverter’s capacity to deliver power.

With all these different effects are taken into account, the 400 watt estimate is just that – an estimate. The compressor may or may not work satisfactorily and at full capacity on such an inverter.

I want to purchase an air compressor what should I look for?

I would like to know what specs should I look for to run my industrial pneumatic speed sander its a 4560 Hutchins I only want to use for about two to three hours .I do some body work on weekends.

I agree that bigger is better when it comes to compressors. I’ve had a few smaller ones, like the ten gallon ones. They never were big enough to keep up with my air tools.

OH! One other thing, steer clear of any compressor that say "oilless". From my personal experience, the compressors that don’t use oil overheat and break down very quickly. I’ll never buy another compressor if I don’t see a dipstick to check the oil.

Can I use my air compressor and a spray gun for the following paint jobs?

All interior work:
I want to prime and latex paint some walls.
I also want to finish oil painting the basement cement floor.

The air compressor is an oiless 8 gallon 150 psi electric model
It easily powers an impact gun
has a regulator knob and two gauges.
The primer is the thickest of the liquids which I want to spray.

I got a HVLP Spray Gun
It has a 2.0 mm tip, All metal construction, and Brass Fan Nozzle with one quart dripless cup. Runs at 20 to 45 psi with 1/4 nps inlet. It has a Air Control, Spray Control, and Fluid Control for making adjustments.

Any advice is appreciated.

The HVLP is the way to go and I would keep the psi down to 30 or so to control the overspray. I also think that your 8 gallon tank is sufficient. It might work the compressor a little overtime because of the constaint drain of the sprayer, but for a one time deal I think will be fine.
I’d do it. Good luck.

How many watts does a 5,000 BTU 120V window unit air conditioner pull?

My air conditioner in my car isn’t working. I plan to get it fixed latter on, but for now, I have an AC inverter that can handle about 300 watts and 120 volts and I think I can come up with something to catch the water. So would it work or would the fan just come on and the compressor hum and blow the inverter?

it wont work. the inverter isnt big enough,but you can check by looking at the tag.second an ac removes heat from air. now where do you plan on exhausting the thing?if your just gonna throw it in the seat and run it, its going to reach around 130-160.see it absorbs the heat and moves it outside.now if your in the exhaust area, its only gonna recirc the air, while constantly adding more heat from the system.so its like blowing on a tea kettle trying to keep it boiling under med. heat.see it stands to reason, that the heat of electric load. plus the heat of compression,and heat transfer,will far outweigh the benefit of trying to remeove the heat from the cab.its kinda like continuing to trade in a vehicle you owe more on than its worth, sooner or later it will get to the point of tipping balance and not helping but hurting the situation.

A Quick Consumer Safety Guide to Basic Power Tools

Throughout your life, your mom has probably told you more times than you’d care to count, “It’s better to be safe than sorry!” Well, your mom’s right, especially when it comes to using power tools and their attachments. Below you will find some quick tips to properly use power tools, all created with your personal safety in mind:

We’re going to start off our guide with a very basic philosophy- always wear the proper safety gear, including eyewear and hand protection. Goggles will keep your eyes safe and gloves will shield your hands from sparks, flying metal fragments, wood splinters and dust that can easily fly through the air while you’re working with any power tool. Your appearance should be the last thing on your mind, with safety being first. If you’re out trying to pick up a member of the opposite sex, please leave your power tools at home.

Our agenda now brings us to a few of the most common power tools on the market. We shall begin with the reciprocating saw, a very powerful hand-held tool used for dismantling entire structures and opening up walls. Keep them on while changing the breakable blades, as they get quite hot as they spin and can take a while to cool down. The 6″ to 12″ blades are incredibly sharp, so always wear the proper hand protection. Always hold this tool with both hands in a firm grip. Never, under any circumstances, attempt to use a broken blade to cut anything, no matter how simple the job seems; it’s a good idea to keep a few spare blades around when you plan on using this power tool.

While we’re on saws, let’s go over safely using a miter saw (sometimes referred to as a chop saw). The particular power saw is used for somewhat tight work and/or detailing thanks to its ability to make sharp, accurate cuts. The miter saw should always be used while it’s raised off of the ground due to the chips of wood that fall out from underneath the tool. If the tool isn’t raised, it will clog and eventually break. And as with any saw, check the blade guard to make sure that it’s functioning properly, and be sure to cut on a sturdy surface.

My personal favorite tool, the router, is the best when it comes to shaping and detailing your wood projects. You might want to check out the depth setting on your router on a piece of scrap wood or metal before working on your project, as you could easily ruin your handiwork. Remember to keep your gloves and goggles on, and start the tool at least 12″ away from your project and bring the tool’s spinning bit slowly into your project. You’ll be safe, and so will your project, when you put safety first.

Dish Network Hdtv Receivers Contain Subtle But Powerful Technology

When you think about HDTV technology you probably think about enormous television sets with movie theater like screens and highly sophisticated sound systems that combine to make you feel like the action is going on all around you. That, of course, is the end goal and purpose of high definition television technology, but high definition television receivers are equally impressive from a technological point of view.

So why are high def receivers so important. In short, they’re important because they are necessary to receive and decode high definition television programming, but in general they aren’t built into the actual high definition television sets themselves. This may seem like a serious omission on the part of the manufacturers, but in actuality not including them was a calculated move on the part of the manufacturers. The reasoning is that there are basically three major sources of high definition television programming. HDTV programming can come over the air in the form of local stations that broadcast in high def, over cables from cable TV providers, or from satellite signals from satellite TV providers. While any receiver that can process over the air signals will do for local over the air HDTV programming, since most people get their TV from satellite or cable TV providers who would provide their own receivers (which are specifically designed to decode their programming) anyway, the manufacturers consciously decided not to build the receivers into the sets.

Therefore, what kind of high definition television receiver you get will largely be determined by which television service provider you decide to go with. That said, Dish Network is a good choice for high def programming because not only does it provide more channels of high definition television, but also throws in a high definition satellite receiver for free.

Right now Dish Network offers two high definition satellite receivers that will cover the needs of just about any high definition television viewer. Both are packed with plenty of user friendly technological features that will make watching TV of any format relaxing and enjoyable. The basic model is the ViP211. The ViP211 has all of the interactive features you would expect to find on any Dish Network satellite receiver. These include the Dish Interactive Electronic Program Guide which will make it easy to figure out what you want to watch among the hundreds of channels you’ll have access to. It also has Parental Control Locks which will allow you to set up safeguards so that you can let your children watch TV unsupervised without worrying about what kind of programming they may stumble upon. In addition, the ViP211 can handle high definition television programming, standard definition television programming, and enhanced definition television.

The ViP622 DVR is the advanced model, that comes enabled with the ability to send a second television signal to a second TV and record both standard and high definition television programming on its internal hard disk. The digital video recording feature on this model is the real attraction. It can record up to two hundred hours of normal standard definition programming or up to thirty hours of HDTV programming. Either way, you’ll have a much greater level of control over how and when you watch TV.

Both of these HDTV satellite receivers from Dish Network contain very impressive technology and will serve their owners well and compliment the more obvious parts of the home entertainment system.

The Real Deal On Portable Air Conditioners

Many people nowadays have cooling systems inside their homes to help combat against the scorching heat that summers may bring. The market is now filled with numerous brands and types of air conditioners that are affordable ranging from the window type, split type and the portable ones that are slowly gaining popularity in homes as well.

A portable unit may seem big and bulky at first glance since it is around 30 inches tall and weighs about 80 lbs. The great thing about it though is that it is a self-contained component that does not require any installation because it can stand by itself on the floor without the need for your wall or window to contain it. Most are also equipped with wheels for easy mobility.

One of the advantages that a portable air conditioner offers is that you don’t need to create a hole on your wall or block a window to accommodate the unit. You can easily transfer it from one room to another eliminating the need to install numerous window type air conditioners in several rooms. It can also help you save on electric bills if you will just be using it in a room instead of switching on the entire centralized system.

It just has a downside of costing more than your regular window type air conditioner. Also, although it has a similar cooling capacity as that with split type systems it can sometimes be noisy compared to the split type kind whose compressor is located outside. If noise really matters for you, look for portable air conditioners that make lesser amount of noise.

You may be wondering if a portable air conditioner is capable enough to cool big and large rooms. Actually, it all depends upon the model. You need to take a look at the cooling capacity of each unit and check the room size that it could productively cool.

Since air conditioners consume a lot of electricity, it would be wise to choose a unit that is energy efficient and has a lower electrical usage. Today the standard and acceptable energy efficiency ratio should be at least 10.

It may come as a shock to you but portable air conditioners are reasonably priced. Their prices have dropped considerably through the years and are not costly anymore. Of course, you can expect units with a higher cooling capacity to cost more. If you want a cooling system but don’t plan on investing in a centralized cooling setup, purchasing a portable air conditioner may be a good option.
