Feature to pick the Best Air Compressor Under $300

Still can’t choose the most desired air compressor under 300? Then this buying guide will surely help you to pick the right compressor based on your requirements within your budget.

Tank Capacity

Investing around 300 dollars, you can consider a larger tank with an air compressor. But before going for the larger tank, realize how much tank capacity will be sufficient for your project. Determining the required run time, amount of air tools and the project type will help you find the right size tank.

For example, a 6-gallon capacity tank will be good enough for a light to moderate-duty task where compressed air is required for a short time. Conversely, if you need to handle a heavy-duty project that requires compressed air for a long time, choose an air compressor with a 10-gallon tank.

Horsepower

An air compressor with a 1 HP motor can handle any light-duty task. But you will need a 3-4 HP motor to complete the medium to heavy-duty compressed air project. Luckily, you can consider a compressor with a higher HP motor for under 300 dollars for your heavy-duty project.

PSI and CFM

Usually, most air tools require 70 to 100 PSI of air pressure with 0.5 to 4 CFM. But you should check the air tool’s user manual to see if it has a specific requirement. Then go for the air compressor that matches the PSI and CFM requirements.

Portability

A portable air compressor is a versatile option for any job site or garage. Investing in a decent budget, you can pick an air compressor with a handle, a wheel, and a rubber foot design tank. To ensure an easier, more stable installation, a pancake-style air compressor would be preferable.

Noise Level

Though air compressors don’t produce extreme noise, choosing a compressor with a quieter motor will be a smart decision. It will maintain a calm environment without disturbing neighbours or families, and let the operator concentrate on the job.

Air compressor maintenance tips

After spending around 300 dollars on the right air compressor, the next essential task is to maintain the air compressor properly. Though it requires less maintenance, some tasks like oil changing, removing, and assembling air filters are very common. Taking care of the air compressor periodically boosts its performance and longevity and makes it worthwhile.

How to change the oil in an air compressor?

Changing oil is a tough task for keeping the effectiveness of an air compressor. Still, you can successfully handle the task by following this process:

Before draining the compressor, run the machine for a while to make the oil warm and thin it’s viscosity. Then remove the fill cap so the air can go into the system. Now pour the oil into a container by removing the drain plug. After removing the whole old oil, change the drain plug using a wrench.

The next step is to carefully and slowly refill the compressor with quality air compressor oil. Check the compressor user manual to see if there is a specific brand recommendation. If the system’s fill valve doesn’t allow you to add the oil at a time, then put some oil in and let it level out, and then add it again. Wait for a while so the compressor can get the right amount of oil. If the compressor has a dipstick, keep an eye on it to ensure the right level. Lastly, change the fill cap and complete the oil changing process.

How to remove and install the air filter of an air compressor?

Replacing the air filter is quite easy task. While somewhere you need to unscrew the air filter, some can be changed by pulling it out by hand. The process is: finding out the air filter of the air compressor. Check whether it is attached with a screw or simply fixed. Then remove the filter by either unscrewing it or simply pulling it out with your fingers. Now install a new filter and fasten the screw or add some liquid fastener.

Routine maintenance of an air compressor

The air compressor maintenance task can be easy, but performing it routinely extends the lifespan of the machine. After learning the maintenance process, apply it every year. It may take a half-hour, but it is extremely essential to enjoy the quality performance of an air compressor for years.

How to Use a Nail Gun with an Air Compressor

Choosing the right type of nail gun depends on the project you need to complete.

Nail Guns: It uses larger-sized nails like 15-16 gauge and is perfect for fitting old furniture. It works better on the wood surface.

Framing Nail Gun: It can handle a larger project, like rebuilding an old tool shed or redoing the patio deck. The framing nail gun uses 2.8mm nails and can complete the task without splitting wood or damaging the top surface of the plaster.

Brad Nail Gun: This nail gun is ideal for fixing small items like kids’ toys or nightstands. The Brad nail gun uses an 18-23 gauge.

Pick the right nail

Nails are generally attached with paper, plastic, or a little adhesive. After firing the nail gun, the heat separates the nail and pushes it into the surface. Choose a nail with adhesive as it fixes securely into the surface. Despite choosing between D-shaped or round-headed nails, since these are ideal for both home improvement and other DIY jobs.

How to Use a Nail Gun with an Air Compressor

The difference between these two shapes of nails is that a nail gun can hold a D-shape about 30% more than its round-headed counterparts. Despite this, round-headed nails are usually connected with plastic while the D-shape is paper-bound.

Use the right compressor

Between electric and gas-powered air compressors, an electric model is more preferable for home use as it doesn’t produce fumes and gases. Apart from these, choose between portable or cable-powered compressors depending on your project type. If you need an air compressor only to run a nail gun, you can choose a cable-powered compressor. Otherwise, a portable air compressor is more preferable due to its improved versatility.

Connect the Air Compressor to the Nail Gun

If you have got a new air compressor, assemble it first. Attach the rubber stopper using pliers and place the wheel under it. Then attach the coupler into the right place and connect the nail gun to the last end of the air hose. After connecting both the compressor and nail gun, make sure they are secure firmly. Now add the required amount of oil to the compressor.

Safety First

Before starting the air compressor, wear your safety gloves and hard hat to remain safe from flying dust particles. Remember, don’t try to clean or adjust the nail gun immediately during/after using it. Plus, don’t run the nail gun through the air compressor where there is a risk of electric sparks.

Start Working

Power on the air compressor and wait until the air pressure builds up inside the tank. While 100-110 psi is the average air pressure for a home-use air compressor, you can adjust it based on your nail gun’s requirements. To sink the nail completely, the machine will require higher pressure, while fixing the nail in place requires average PSI. After adjusting the PSI, push the nail gun nozzle completely against the working surface to drive the nail.

Finishing Off

Remember, you will have to disconnect the nail gun as the last item. Until you power off the compressor, remain careful about the nailgun without considering whether it is loaded or not. After finishing the task, wait for a while before switching off the air compressor. Slowly turn the regular down to reduce the pressure and switch it off after reaching the end.

Then release the remaining air by opening the safety valve and drain valve. Now disconnect the nail gun from the air hose and clean it using lubricant. After cooling down the air compressor and nail gun, store them as the last step.
