Do I really need an air receiver?

Short answer? Yes, absolutely. And here’s why…

What does an air receiver do?

An air receiver is effectively a storage tank for air.

It’s an important component of your compressed air system, though, because it helps the compressor manage peaks and troughs in demand.

When demand is relatively low, the receiver is where the ‘spare air’ sits.

Can my compressor work without an air receiver?

Technically, yes, but you wouldn’t want to run a compressed air system without a receiver, for several reasons:

  • A receiver tank helps the system manage fluctuations in demand that occur during every working day. Without it, you’ll find the compressor having to work harder as loading and unloading cycles increase. And when you force the compressor to work harder you increase wear, maintenance requirements, energy costs and the risk of breakdown.
  • If you run multiple tools from your compressor, you’ll probably find times when you’re using some or all of them at once and other times when there’s just one tool in operation. The air receiver (with the correct capacity) ensures there’s always enough air power in the system to meet demand.
  • When you compress air you create water. Driers and filters can help remove that moisture, but an air receiver will usually be the starting point for draining moisture. The receiver is the sump into which water within the system gathers – which is why you’ll find a drain valve in your receiver. Without the receiver, there’s nowhere for the water to gather but within the airlines, and that can present a risk to your products, air tools and the longevity of the compressor itself.
Why are some receivers mounted on the air compressor?

Compressor mounted air receivers are primarily a space saving device. You’ll find smaller (up to 26kW (approx.)) compressors/receivers are often supplied as a single unit, creating a smaller footprint that’s easier to find room for.

More powerful compressors will typically have the receiver as a separate unit.

How do I choose the right size of air tank?

As a (very) general rule of thumb, you’ll need a compressor with a capacity 6-10 times the flow rate of the system. So, for example, if your air compressor has a rating of 25 scfm, the receiver tank should be capable of storing a minimum of 150 cubic feet.

BUT it’s important to note that lots of variables can affect that. Peak demand, the flow and pressure you need and the type of air compressor you’re using could all affect the required capacity of the air receiver, so to find the ideal one for your business, talk to us.

Can I buy a standalone air receiver?

Yes. Most air receivers are bought as part of a full compressed air system, but if you need to buy a standalone receiver (perhaps your old one has reached the end of its working life or you’re running more tools from your compressor and need a larger receiver, talk to us.

Which air receivers do you supply?

You’ll find air receivers with capacities ranging from 50 to 5,000 litres at Algar Air.

Each has a pressure release valve, auto drain (to remove condensate from the receiver automatically) and a test certificate, and each conforms to BS5169.
