What is compressed air for diving? It’s a compressed gas used for breathing underwater. It’s a mixture of different gases, mostly oxygen and nitrogen. It’s compressed to a high pressure to be stored in a tank and used underwater. It’s also used in blowing tools like nail guns and air horns.
So, let’s look at everything compressed air for diving entails.
In this post we'll cover:
Comparing Regular Air Compressors to Scuba Air Compressors
What’s the Difference?
Regular air compressors are great for a lot of things, but they’re not so great for scuba diving. That’s because scuba compressors are specially designed to fill the tanks that divers use to breathe underwater. They’re also used by firefighters and hospitals for oxygen tanks.
So what’s the difference between regular air compressors and scuba air compressors? Here’s a quick rundown:
- Scuba tanks need to be filled at very high pressures – around 3,000 psi. Regular air compressors can’t reach that kind of pressure.
- Scuba air needs to be clean. Scuba compressors are designed to filter out moisture and other contaminants, so the air you breathe is safe.
So What Does That Mean for Me?
Basically, if you’re planning on going scuba diving, you’ll need a scuba air compressor. Regular air compressors just won’t cut it. That’s because scuba air compressors are built with all sorts of filters and moisture separators to make sure the air you breathe is clean.
So if you’re looking to take the plunge, make sure you get the right air compressor for the job. Otherwise, you might end up with a nasty surprise!
What’s the Deal with Scuba Compressors?
The Basics
So you’re curious about how scuba compressors work? Well, buckle up, because we’re about to dive into the deep end of the pool. Here’s the gist:
- The compressor sucks in air through an intake filter and squeezes it up to around 100-140 psi before pushing it out. This process generates a lot of heat, so there’s a coil or intercooler to help keep things cool.
- The compressor sucks in air through an intake filter and squeezes it up to around 100-140 psi before pushing it out. This process generates a lot of heat, so there’s a coil or intercooler to help keep things cool.
- The air is then compressed again, this time up to 800-1000 psi. It’s cooled again and sent through a moisture separator.
- The air is then compressed again, this time up to 800-1000 psi. It’s cooled again and sent through a moisture separator.
- The air is compressed once more, this time up to a whopping 5,000 psi. It’s cooled and sent through another moisture separator.
- The air is compressed once more, this time up to a whopping 5,000 psi. It’s cooled and sent through another moisture separator.
- Finally, the air is processed through a back pressure valve, which is usually set between 2,700 and 3,300 psi. This valve helps keep the compressor running balanced and affects how the filtration works.

The Bottom Line
So there you have it – the basics of how scuba compressors work. It’s a complex process, but the gist is that air is sucked in, compressed, cooled, and sent through moisture separators before being processed through a back pressure valve. Now you know!
What’s the Pressure? Comparing Low and High-Pressure Compressors
The Lowdown on Low-Pressure Compressors
Are you ready to take the plunge and dive into the world of low-pressure compressors? These lightweight wonders are perfect for surface supplied diving, and they provide air to divers through a hose. But don’t let their size fool you – they can still pack a punch! Here’s what you need to know:

High-Pressure Compressors: The Heavyweights
High-pressure compressors are the big boys of the scuba air compressor world. With pressures ranging from 3,200 to 5,000 psi, these bulky bad boys are commonly found in commercial diving and dive shops. But don’t let their size intimidate you – they’re great for filling tanks! Here’s what you need to know:
- They provide air pressures between 3,200 and 5,000 psi

What You Need to Know About Operating a Diving Air Compressor
Do I Need a License?
If you’re thinking about becoming a diving air compressor operator, you might be wondering if you need a license. The answer depends on where you live. In some areas, you’ll need to be certified as competent to operate a diving air compressor and fill high-pressure cylinders. In other places, you’ll need to be able to use the equipment and check cylinders for compliance, but you won’t need a license. And in some places, there’s no regulation at all. No matter where you live, you’ll need to follow the national and/or state occupational health and safety regulations.
What Else Do I Need to Know?
If you’re going to be an air compressor operator, there’s a few other things you should know:
- Make sure you know the safety protocols for your area.
- Make sure you know the safety protocols for your area.
- Get familiar with the equipment and how it works.
- Get familiar with the equipment and how it works.
- Learn how to check cylinders for compliance.
- Learn how to check cylinders for compliance.
- Familiarize yourself with the national and/or state occupational health and safety regulations.
- Familiarize yourself with the national and/or state occupational health and safety regulations.
- Get certified if you need to.

So if you’re thinking about becoming an air compressor operator, make sure you know the rules and regulations for your area. And don’t forget to brush up on your safety protocols!
Understanding the Pressure of Air Banks
It’s no secret that air banks are an integral part of diving, but what exactly is the pressure behind them? Let’s take a closer look.
Surface-Supplied Diving Compressors
Surface-supplied diving compressors are low-pressure and high-volume, meaning they can provide air to multiple divers at depths of up to 60 metres. Here’s what else you need to know:
- They supply air directly to a diver through a gas control panel, also known as a “rack”.

- Their output is usually between 6 and 20 bars (100 and 300 psi).
- Their output is usually between 6 and 20 bars (100 and 300 psi).
Compressors Used to Fill Scuba Cylinders
These compressors are used to fill diving cylinders and storage cylinders or banks of storage cylinders. Here’s what you need to know:
- They have a high delivery pressure and may have a low delivery volume.
- They have a high delivery pressure and may have a low delivery volume.
- Common scuba diving cylinder pressures are 200 bar (2940 psi), 3000 psi (207 bar), 232 bar (3400 psi) and 300 bar (4500 psi).
