Types of Fortress Air Compressors by Harbor Freight

There are different types of air compressors designed by fortress depending on the workload, tank size, power, and pressure. We’ve given their names below:

By Tank Size

Choosing an air compressor depends on the work that you want to do. If you want to inflate your car tires, then 1-5 gallon tank size would be enough but if you are thinking to run an air pump service station then 6-10 gallon compressors perfectly work. For the industrial level, you will need a big size tank to perform heavy operations, from 10 gallons onwards the number will increase if you want to store a huge amount of air in a container. Fortress is manufacturing 10 types of high-performance air compressors according to their tank size, we’ve given their names below:

  • 1 Gallon
  • 2 Gallon
  • 4 Gallon
  • 5 Gallon
  • 6 Gallon
  • 8 Gallon
  • 10 Gallon
  • 26 Gallon
  • 27 Gallon
  • 60 Gallon

By Horsepower (HP)

Horsepower is one of the most commonly used metrics in the automotive industry and is used to measure the power of an engine or motor. Air compressors also have motors ranging from low to high horsepower. For home, 1 or 1.2 HP air compressor is the best option but at the industrial level, you will need 1.5 HP, 2 HP, and higher. There are 3 types of compressors designed by Fortress according to the horsepower.

  • 1.2 HP
  • 1.5 HP
  • 2 HP

By Pressure (Psi)

Low psi air compressors are used in garages and workshops, because they have a normal size tank from 30-100 psi that is enough for filling the air in tires, airbrushing, pressure washing, and others. Likewise, high-pressure compressors ranging from 100-200 psi or above is used at the industrial level that require a high amount of gas pressure. According to psi ratings, Fortress is providing four types of air compressors.

  • 135 psi
  • 175 psi
  • 200 psi
  • 225 psi

Fortress Ultra Quiet Air Compressors

It is a fact that air compressors need to be quiet for workshop or home use because too much loudness is irritating for everyone and produce noise pollution. Fortress also manufactures advanced quality air compressors that produce less noise and work for a long time. A foam or rubber-type material is used in it that will help to remove the noise. This oil less compressor is much lightweight that anyone can carry with hands and it requires not much maintenance as other machine needs. You need not worry about corrosion because it is rust-free. You can choose the silent one compressor instead of a Jobsite that is louder. Personally, we also love and recommend having an ultra-quiet compressor.

Fortress Harbor Freight also gives their customers a 90 days warranty in which they can replace the air compressor if it caused any issue. It is very rare because fortress compressors are of high build quality and you are going to run them for a long time.

Unluckily, if you have faced a problem within the warranty time then you can contact the Harbor Freight team to change it. An order number or payment receipt is compulsory if you want to replace your air compressor with a new one. You will also get your money back but no shipping refunds are added to it.

Genuinely, if your air compressor stopped working during the first 3 months of its purchase then you will definitely claim refunds or a new machine. But, in the following circumstances you can’t apply for a warranty:

  • Damaged device

  • Unnecessary replacement
  • Unprofessional Installation

So, those who made these mistakes will not eligible to apply for a refund.

  1. My Fortress 56403 compressor needs a new compressor unit to set on top of the tank due to an air filter failure. I find none listed as available in Harbor Freights’ parts lists, nor any of the interior parts for the compressor unit to replace them, and the stores don’t carry any parts. I guess I’m stuck with a piece of junk.
