A common questions asked is why do I need an air dryer for my compressor? Typically, air compressors produce water, and although the water
can be drained, there can still be aerosol and vapour droplets that are present. This is because water cannot be compressed. Water can
damage your compressor by corroding the valves, pipes and machinery controls, which will cost you time and money to resolve. In
the long run, the cost of a new compressor is a small price to pay compared to the loss of production that could potentially arise due to
water damage in your compressor.
How do I know my compressor needs an air dryer?
Pay attention to the manufacturer's labels on the compressor - it may say that dry air is needed
Rusting, corroding, mould, vapour is present in your compressor
Your air tools are showing water droplets
The tool exhaust sprays our water vapour
Why is it important to know the size of my dryer needs?
When sizing an air dryer that keeps up with your application needs; it is important to get the right fit. A dryer that is too large will
cause harmful wear and tear long before normal, opposed to having an undersized dryer can lead to poor air quality
What questions do I need to think about when sizing a dryer for my compressor?
What is the desired dew point (how dry compressed air needs to be – this will determine whether it is a refrigerated or desiccant style
• How much CFM will your compressor be sending through the dryer, and at what pressure?
• What are the ambient conditions of the dryer (ambient temperature, elevation, etc.)?
• What is the inlet temperature of the air going into the dryer?
Answering these few questions will give you a good start on selecting the right dryer technology and the appropriate size for your
Remember, a desiccant dryer consumes 2% -20% of your CFM as purge air during the regeneration cycle of the vessels. With that in mind, you
will need to make sure you make the necessary arrangements. If it is a new install, the compressor will need to be sized appropriately to
compensate for the CFM loss during the purge cycle. If it is an existing install, you may have to upgrade the compressor. Ambient conditions
and correction factors also come into play.
Another thing to think about is the upfront costs of purchasing the air dryer and its installation aren’t the only costs that are incurred
in total. There are other costs that also need to be considered here, such as additional energy consumption and, the way the dryer is
regenerated (in case of desiccant air dryers).
The bottom line
Air compressors are a significant investment, crucial for many businesses operations through New Zealand, and the world, and sometime
they need to power some very important tools.That being said, keeping your compressor in tip top shape, regular services, having an air
dryer etc, ensures a longer lifetime of your compressor and will increase your production levels by reducing equipment failure issues
due to corrision of components. In conclusion, air dryers are worth every penny spent.

Air compressors are used in many different applications and provide essential compressed air to many businesses and individuals with
different air needs. No matter what your CFM, PSI and HP requirements are, the electronic controller on your air compressor is the
motherboard for keeping your unit running as efficiently as possible. It is your eyes into your machine.
The emergency stop, "e-stop", is for true emergency situations only. When hitting the e-stop, all power is halted from the machine
and the unload process isn't achieved. The emergency stop button is intended to help with possibly hazardous situations that are developing.
Common conditions of having to use the e-stop is the misuse of the equipment in ways that weren’t intended, predictable failures not
addressed or failing to consider all the foreseeable uses of the compressor. Read More…
Air compressors are helpful for an enormous range of applications such as air filling, packaging, tools, HVAC control, and more! One
possible drawback is the amount of electricity they use; air compressors can be a huge drain on energy if used inefficiently. If you are
running them too long, allowing leaks to exist, or using the wrong type of compressor, you are wasting energy and money. This article will
go over some of the biggest power-wasters and how to
