Dusting computer components continues. Page one about dusting computer components is here.
All of these types of compressors come complete with a discharge coupler installed at the compressor air outlet, into which you will plug your connector for your hose.
If the hose is not part of the kit that came with your air compressor, you will need to acquire one, along with a connector that fits the coupler on the compressor. You will also need a blow gun to turn the compressor dusting of air flow on and off as needed.
You will want to use a desiccant type air dryer , installed downstream from a general purpose air filter, to remove water vapor from the air stream.
Though they are portable, the ones with the 2-3 gallon tank are a bit bulky, bulky enough to make transporting them, along with your other equipment, a bit problematical. Go to your compressor store and see what I mean.
The bigger problem from my perspective is noise. Cheap compressors are noisy. Again, visit your compressor store and ask them to plug in the model that you are considering to see if you can handle the noise level. Let the compressor run until it reaches its cut-out level and shuts off, so you can hear the unloader valve work too, as that adds another noise element.
You will, eventually, need compressor repair and there is no repair depot familiar with the brand, you may have a problem getting it fixed.
Getting a tank filled at a garage is becoming more difficult, as gas stations appear to be getting out of the free-compressed-air business.
When you buy your tank, you will need to have the store explain to you how you fill the tank. There are various adapters available.
This won't do for you in trying to dust off computer components.
You will also need to connect the desiccant air dryer into the circuit.
You can do this by cutting the hose and adding fittings to screw into the dryer, or simply add the dryer at the end of the hose just before you add your blow gun. You can plumb the dryer with couplers and connectors or the appropriate fittings that fit the dryer ports.
The best thing to do is to visit the following pages for complete information on couplings, connectors, and fittings:
The compressor will come equipped with a coupler on the discharge pipe from the tank.
You will need a connector to insert into that coupler, an air hose to be attached to the connector, a coupler for the other end of the hose, a male connector that screws into your dryer port on the supply side, and perhaps a male coupler that threads into the other side, and a coupler that connects to the connector in the blow gun. And don't forget the blow gun itself.
