The industrial machinery field develops, expands, requires auxiliary equipment to improve process efficiency. The air compressor is a reasonably familiar device, especially in mechanically manufacturing and operating machines in different large and small factories and workshops.

In terms of particular specifications, the air compressor has its safety standards that need to be ensured. Therefore, users choose to buy the best-used air compressors based on technical safety and usage criteria. If you want a compact and compact design and compact size, a portable air compressor is a great choice.

Our following article will show you the highlights of the best portable air compressors and things to keep in mind for the best decision.

Buying guides

The distribution market for the best portable air compressors is diversified, with many different sources and sources. Air compressors with other characteristics, users, need to consider and evaluate the proper criteria to choose the best portable air compressors with efficiency:

1. Oil-free or oil-free air compressors

Many users are hesitant to choose to buy an oil-free or oil-free compressor that will be more suitable. The following description will help users to have reviewed and choose the right purchase between the two types:

  • Oil-free air compressors: In compressed air, 100% clean, used in areas where the compact air quality is strictly required. Examples of sectors: healthcare, food processing, and dentistry that guarantee clean standards.

  • Oil-based compressors: The compressed air contains a small amount of oil vapor. Therefore, the cleanliness is not high, popular application in mechanical engineering, car garage, where machinery operates, including oil, to protect equipment, machinery, and details. The price is lower than oil-free air compressors.

2. Capacity and efficiency of compressed air

Before deciding to buy a portable compressor, you need to estimate the type of work and flow, capacity, the pressure of pneumatic tools to choose the right product. Buy pneumatic pump models with too weak power compared to the actual work requirements. It can reduce the factory's operational productivity. On the contrary, if you invest in an air compressor with a too high capacity for your actual usage, it will waste money and cost much money to maintain the equipment's operation, such as engine oil and power consumption.

Besides, users should pay attention to compressed air efficiency. Typically, air compressors will experience a leak of some compressed air. Buyers need to choose a machine with a less than 10% leakage rate suitable for high work efficiency and reduced fuel consumption.

3. Air compressor power source

The larger the capacity can lead to the higher the voltage that is used. Large-capacity machines, used for a long time, need more inverters. Users need to pay attention to the appropriate power source parameters.

4. Design and installation of air compressors

Choose the best portable air compressors installed and used suitable for the working space and area. The portable air compressor is not too large, ensuring easy installation, enough space to run the machine, convenient cooling, and maintenance. Machine design is equipped with wheels for convenient moving, installing equipment, electrostatic coating to protect the device.

5. Heat the air compressor 

The compressed air process of the portable air compressor will create a lot of heat and pressure. Usually, there will be cooling oil in the compression chamber. Still, some models will have no oil to ensure the purity of the compressed air. Users should pay attention to the machine's ability to cool down. The appliance operates stably, not too hot, overloaded during operation. Portable Air compressor line uses cooling oil for the mechanical fields, manufacturing, construction machinery with low purity requirements. In the medical area, where food needs 100% clean compressed air, the oil-free models will be the top priority. 

6. The noise of the machine 

For environments requiring high quietness, the user should pay attention to the noise specifications. This is to avoid affecting the health of the user as well as everyone around. Therefore, a product with an acceptable noise level will be the best solution for limiting this problem. 

7. Brand name and price 

With technical equipment, strict safety standards, machines with an exact origin from reputable brands will be the first choice because reputable brands will calculate the standard design and verify the quality and specifications before putting them into operation. Warranty policy helps users operate the device efficiently, stably, and in the long term. How much does the compressor cost? Consider the price with the financial ability of family, work. Users compare the price, technical characteristics with the product use efficiency to choose the best product in terms of performance and cost. 

8. Warranty on air compressors

The best portable air compressors will always come with whole policies and warranties to ensure customers' best interests. Suppose during the warranty period. There are no errors in the machine. In that case, the customer can ultimately bring the device to the warranty center for free repair.

The genuine air portable compressor's warranty card will have complete information such as date of purchase, warranty period, warranty unit, warranty conditions, and be stamped with the company's red stamp. Counterfeit suppliers, inferior quality machines prone to damage will not have a warranty card or the warranty period is often very short. Usually, a device's warranty period lasts from 6 to 18 months, depending on the manufacturer. This is one of the factors that help in choosing to buy a quality air compressor.

FAQs

1. Is it okay to leave the air compressor full?

Well, it disappears after each use. Avoid leaving standing water in the tub corroding and weakening the tank. Take the air out and open the drain valve for a while to let the steam escape. I also left the valve on the bottle open and turned it on to keep the inside dry.

2. What are the three types of compressors?

The three most common types of air compressors are plunger, rotary screw, and centrifuge. Reciprocating compressors are considered actively displaced, increasing the air pressure by reducing its volume.

3. At which PSI does the tire explode?

Standard tires are inflated to about 30 to 35 pounds per square inch. In hot weather and highway conditions, the air temperature inside the tire rises by about 50 degrees. That increases the pressure inside the tire by about five psi. Tire burst pressure is about 200 psi.

4. Why does the portable air compressor explode?

The leading cause of compressor explosions is corrosion. When an operator does not completely drain the water accumulated in their tank, water can cause decay, weakening the tank until compressed air breaks the tank.

5. What if the air compressor does not drain water?

If you do not completely drain the tank's water, moisture will accumulate in the tank, meaning the tank's water could explode and harm someone. The same is true for all air compressor tanks. The water inside is pumped with air into the tank. If not periodically rinsed, the inside of the tank will rust.
