Best Air Filter For Plasma Cutter [Things to Consider When Buying]

Are you trying to find the best desiccant air dryer for plasma cutter? Here’s a short guide that will help you get to choose the right product.

# Air Filter Type

First things first, the most crucial part is selecting the right air filter type. Apart from numerous kinds, it is in your best interest to pick a desiccant dryer or refrigerated dryer.

A. Desiccant Dryers

Most air filters fall in the desiccant dryer category. These filters compress air in a ‘tube’ like containers. And these containers are filled with useful absorbents (usually beads), which are known as ‘desiccants’. 

Now, if you closely analyze, 4 out 5 air dryers we have mentioned here are desiccant. They are tube-shaped and professionals love to have them as a part of their cut-50 plasma cutter. Desiccant dryers are easy to use and filter out all the unwanted particles from the air.

B. Refrigerated Dryers

Refrigerated dryers are mostly found in tower-shapes, and utilizes the same refrigeration process that is used by your home refrigerator. However, these air purifiers cool the compressed air and depart moisture from it in the form of water. After the condensation process, all the liquid is collected and transferred to the draining unit.

# All-Rounder Contaminant Remover

Now that you are aware of the two main air filter types for your plasma cutter, so try to look for the one that performs effectively on both liquid and dry contaminants. In other words, find the air filter that can pull out dust, debris, water, and all other pollutants from entering your plasma cutting lines, and provide 100% refined air.

# Material

Although air filters are made of different materials, the majority of them are designed using aluminum, especially the desiccant dryers. They are safe and have a durable life.

# Size

When choosing an air filter for your plasma cutter, don’t forget to get the right size. Some plasma machines have 1/4-inches NPT, while others require 3/4 and 3/8-inches lines to assure a perfect fit. Keep in mind, that size accuracy is requisite, as it leaks-free the entire unit.

# Pressure

Always opt for high-pressure air dryers. The minimum acceptable range is from 100 PSI to 200 PSI. And, the higher you go the better performance you would get.

Is it Worth Buying an Air Dryer?

Buying an air dryer or filter for your plasma cutter could be extremely beneficial. How? Well, suppose you’re planning to use the plasma cutting machine for more than 8 hours a day. So operating the tool without an excellent air filter requires more investment in the consumables to get optimum results in the long run.

However, that would be an expensive way to complete the job. Contrarily, attaching an air filter to any budget plasma cutter unit will save your money. More to this, it will enhance the plasma cutter’s life. And of course, you won’t have to purchase some pricey consumables.

What is the Advantage of Air Dryer for Plasma Cutter?

The plasma cutting method relies on the principles of physics. The plasma torch is designed to produced gas swirl patterns and proper flow rate to experience outstanding arc velocity. The dry air includes 20% of oxygen and 80% of nitrogen, and the torch is engineered to work according to the combination of these gases within the same amount.

But when there’s additional moisture due to the contaminated air, it changes the entire science. The increased oxygen and hydrogen levels damage the orifice shape and nozzle bore. And as a consequence, the cut quality is negatively affected.

Therefore, connecting an air dryer to your plasma cutter provides filtered air. Moreover, it not only stops moisture but even stops harmful particles from breaking into the plasma equipment.

So, undeniably, an air dryer is a boon to all the welders out there, who are always willing to prove their mettle on the metal.

FAQs

#1. Why a plasma cutter requires an air dryer?

It prevents your plasma cutter from polluted particles. It’s a must-have accessory if you want to endure cleaner cuts every time you turn on your plasma cutting tool.

#2. For how long does the air dryer keep the plasma cutter tip workable?

It depends on consumption. Therefore, theirs is no fixed period. But, if you are not using an air filter/dryer with your plasma cutter, then expect 2 to 4 days plasma cutter tip durability. Contrarily, using an air dryer prolongs the duration.

#3. What is the shelf life of desiccant?

You can keep desiccant packs for a maximum of 12 months. Nevertheless, make sure that any open packet must be sealed again within 15 minutes.

Buying the best desiccant air dryer for plasma cutter could be a challenging, as well as, time-consuming process. But we hope that our researched products can be helpful to you. For sure, the decision is in your hands.

Yet, we do suggest going for the Edge Industrial’s 3-stage dryer if you’re into some regular heavy-duty welding schemes. It can capture 0.01 microns pollutants from the air, and also eliminates water and oil components from the atmosphere. So, if you are working in a highly-contaminated area, then desiccant dryers should be at the top of your list.

And if you are more concerned about moisture rather than dry contaminants, then Ingersoll D42IN comes with a 203 PSI pressure that is suitable to capture contaminants as tiny as 1.0 micron. Refrigerated dryers are best for splitting up oil and water from the air. So, if you’re workplace has high moisture in the air, then selecting the refrigerated dryer would be a smart choice.
