If you’re reading this article, you must wonder how to compress air into a tank. Portable air tanks generally have a capacity of 5 to 8 gallons. The minimal weight of the little cylindrical tank makes it perfect for delivering air to a low-pressure car tire. The air tank’s modest volume and pressure are usually inadequate to fill a fully flat tire. The portable air tank can fill four or five basketballs and may also be used to inflate tiny air beds. In this quest of how to fill a portable air tank, you will come across several techniques.

To fill these portable air tanks, a normal air compressor is usually deployed. Once the compressor’s connection is hooked to the tank, air will begin to flow into it. Maintain an eye on the pressure gauge to determine when the tank is full and disconnect the line. Then, to assure that you may reuse the tank whenever you need it, utilize and conserve it suitably. But how long does air compressor take to fill? Well, that is up to which technique you apply.

The following are techniques essential if you want to know how to fill a portable air tank. So if you want to refill air tank, keep reading:

How To Fill A Portable Air Tank

Method 01:

Steps 01: 

  • Full-service gas stations and truck stops are the most desired places for air compressors.
  • You may fill your tires using the same pump that automobile owners use. Inspect your air tank for damage before filling it, and replace it if there are any cracks or corrosion.
  • Scuba shops, paintball parks, and select sports goods stores may also be able to fill your tank.
  • If you have an air compressor, you may deploy it. A home improvement shop may have one.

Steps 02:

  • Set the tank on the ground and attach the compressor line to the metal valve on the tank. It is located next to the pressure gauge and is composed of brass, making it difficult to overlook.
  • Place the hose nozzle over the spout on the fitting’s back end. Connect the air hose to the spout as soon as possible. It should fit perfectly over it, with no gaps.
  • Attach the compressor hose to the fitting opposite where the tank’s airline attaches. This is very important for air tank refill.

Steps 03:

  • Start the air compressor and follow the guidelines on the pump. The compressor is generally activated by pressing a button. Usually, you’ll need to pull a trigger on the hose to start pumping air.
  • The amount of time necessary to fill the tank is determined by its size. Allow roughly 20 minutes to fill the tank.
  • Turn off the tank’s valve. It will continue to receive air.

Steps 04:

  • Add water to the tank until the pressure reaches 85 to 125 psi. Check that you can clearly see the pressure gauge. As the tank fills, the gauge’s needle will begin to move. Stop adding air when the needle on the gauge hits the red zone.
  • Filling the tank beyond the authorized level is risky; thus, avoid going overboard.

Steps 05:

  • Disconnect the air hose when the tank is full. After pumping air, pull the hose from the brass fitting. All that remains is to re-holster the hose and transport your tank home!
  • Because the tank is now heavier, move it with caution!

Method 02: 

Steps 01:

  • Exhale in a well-ventilated, safe location. The trapped air is dangerous to inhale and may be combustible. Always exhaust your automobile outside, away from other people.
  • Keep your hair, clothes, and jewelry away from the tank’s hose. Keep the tank away from open flames, and don’t permit minors to employ it for their own protection.

Steps 02:

  • Connect the air hose to the tank and inflatable object. Slide the air hose onto the brass fitting after silencing the pressure gauge. It should be attached at the opposite end of the ringed spout you used to fill the tank.
  • When you buy the tank, it normally comes with an air hose.
  • Connect the hose’s opposite end directly to the object you intend to inflate. Hoses may be obtained at home improvement and auto parts shops.

Steps 03:

  • Turn on the tank’s steering wheel. Near the brass, fitting is a helpful little wheel.
  • Turn the wheel counterclockwise to open the tank’s valve. Immediately, you should hear air pouring out of the tank.

Steps 04:

  • Make the object bigger to a safe size. Air will continue to flow until you shut the valve again. Keep a frequent check on the inflatable item to ensure it is filled to a safe level. Over-inflated things are more prone to explode.
  • A properly inflated item will feel firm to the touch. It should not protrude or look to be ready to explode.
  • Turn the valve clockwise to halt the airflow. If you hear hissing from the tank, this indicates that air is still moving. Check that the valve is fully closed.
  • If you’re going to retain the tank for a lengthy period, make sure it’s absolutely empty before disconnecting the hose.

Now that’s how to fill a portable air tank.
