Choosing the best air regulator and filter for an air compressor is not that simple as there are so many products on the market. Here is what you should look for when choosing the best air compressor filter dryer for your preference –
Draining is very important when it comes to buying an air compressor unit. Right now, there are three drainage systems available on the market.
One is a manual, which requires you to press the valve to drain it by yourself manually. The second one is semi-automatic which drains when there is no pressure; moreover, it closes when the air starts passing. Lastly is the automatic one, which by name you can guess drains itself when the bowl is ½ way full.
The water separator is what gets all the pressure from the air compressor. So, it needs to have the capacity to handle the load of the air compressor. So, look at the box while buying.
The bowl withstands a lot of pressure, and that is why it should be of the highest quality possible. A metal bowl is much more durable than a regular plastic one for obvious reasons.
Using and Maintenance Guides
Step 1 – the tank and inlet need to be at a good distance.
- The air inside cools and then passes through the filter; that is why the tank and inlet should have a good gap of around at least 50 feet.
Step 2 – Wall mounting
- First, you will have to connect the L bracket with the filter and screw those in tightly.
- Then take a solid piece of wood and place the filter on top to screw that in place.
- After that, the whole thing is ready to be mounted on the wall.
Step 3 – Tank hose connection
- You will take the tank hose and place it in the filter’s inlet and secure that in place.
Step 4 – Run a drill
- Now connect the air tool hose with the end of the filter.
- After that, give it a test run and see if everything is working properly.
Maintaining that unit is very important after setting up the machine. Many people tend to slip when it comes to that; moreover, the device will not work properly without proper maintenance.
Here is how you should do it –
- Have a maintenance schedule to keep track of when was the last time you cleaned your air compressor. Moreover, try to keep a regular check run through of cleaning and maintaining the unit.
- Keep the machine clean from any external dust or rust as it will less pollute airflow and also help the machine stay in shape for longer.
- Your compressors have filters, and you should change them on a regular basis after any work.
