There are many interpretations of "Small Industrial User".

We don't care whether you are a small one man band or employ 500 people, we know that we can help you and would like to welcome you to our list of satisfied customers.

Most small concerns start off with a small piston compressor and at a later date move on to a vane or screw compressor. This is where the trouble starts.

Because of price constraints most people look for used machines, in itself that's not a bad thing, but you must be realistic about what you want and what you are prepared to pay. You won't get a good used machine for silly money.

If you do get a cheap machine it is usually troublesome and you could easily regret buying it. Used industrial machines are not cheap to repair and can be a nightmare - all our used machines have a warranty.

 Should you choose a Refurbished or a New machine?

Without a doubt a new machine is the answer if finances allow it, the next best alternative is one of our refurbished machines which are much better value than taking pot luck on the secondhand market.

The best advice I can give you is to have a reality check and keep your feet on the ground. If compressed air is important to your production then some tired out old heap of a machine will be nothing but trouble and very costly to keep going..

I am amazed when people tell me what they want and  then say they want to spend 5-600, when what they want will be several thousand at least - especially when they tell you about the tens of thousands they have spent on the equipment that this 500 compressor is going to run for 18hrs a day. Then they say that they need good quality dry air as well, still it gives me a smile on a busy day.

So what do I need to buy?

Buying a compressor is just the start of things, you will need to store the air in a receiver, do you need to refrigerant dryer, do you need some proper filtration.  That's a full basic system, not every one needs all of this and some need a lot more.

Its all a matter of knowing what you want and how to go about it. Lets break it all down into individual parts and see how we go.

What type of Compressor?

Pistons are the best known and usually the cheapest, they produce cheap, hot, crude and wet air - everything you don't want. However a top quality piston compressor will be very nice, but they cost thousands new and so you won't buy one in the high street or a used one on ebay.

Screw compressors are very popular. Good ones are fantastic but can be expensive, Lesser  ones are a nightmare even when new. You need to take great care with a used screw compressor, most run at up to 9K rpm and will be very costly to repair if they have been neglected. If there is no service history or warrantty - walk away,

Vane compressors are also very popular. However a word of caution, the same as screw compressors they can be expensive to run if you buy an old neglected unit - so you still need extreme caution.

Air Receivers

Many machines are mounted on a horizontal receiver and this can be space saving. Other machines have a separate receiver and this would normally be a floor standing vertical unit. A typical size would be 250 or 500ltrs although you can go up to several thousand litres for a large factory.

All air receivers must have a current test certificate, this is now a legal requirement, so don't go buying a 25 year old tank off ebay. You will be best served with a new unit, but we have some good used ones all with new air certificates. We can supply brand new receivers at good prices.

We are also able to retest units for you so that you can comply with current legislation.

Dryers

If you need dry air then a refrigerant dryer could be the answer. Another word of caution - dryers like to be serviced and looked after - tired old units with no gas in them will do nothing for you.

The general rule of thumb is that used units are usually troublesome and so we refurbish and re-gas all of ours to ensure that all is well.

New ones are around 1000 for a new 40cfm unit from a decent manufacturer - you can get cheaper but our experience is that they are usually cheap and cheerful - this is not what you want.

Filters

There are filters and filters. Forget about cheap units for 30 in the high street, they are basically useless. The best ones are coalescent filters and a 40 cfm filter would be about 175 each and you need one on the inlet and one on the outlet to the dryer. They are very efficient and do what you expect a water trap to do. Bigger ones are correspondingly more expensive.

Water Traps

One of the most mis-described  of things. They never stop water only moisture, a very different thing. Of course this is better than nothing, but will not give you dry air. Dry air is expensive to produce, you have been warned.

So you can see there is more to this than just a compressor and so where is a few hundred pounds going to get you.

Top quality air is very expensive.

Conclusion

Most people don't help themselves when it comes to compressed air and what they really want.

If you have a cheap and miserable old compressor, making more heat than a blast furnace you will have hot wet, dirty air. If you decide to try and clean up this type of air you will be fighting a losing battle and it will be very expensive.

You would be better off getting a decent compressor which is suited to your needs and is running properly - the air quality will be much better than the machine mentioned above. From this point you can move forward.

A receiver and a decent small filter will be enough for many applications, if you need it a little better you can fit a coalescent filter and that would be reasonably fair quality air.

If you need to go better than this, then you will need a refrigerant dryer and a pre and after filter unit, this makes things much better.

After that you are heading for laboratory quality air and that is another world.

So be realistic or it will all end in tears.

Don't be fooled by glossy brochures and salesmen in shiny suits.

Even when you accept all of the above and are ready to go forward you will need to speak to a competent person who can give you the proper advice.

Most salesmen can only sell what they have, and usually out of a brochure, I am always amazed at how little they know about compressors. They are always more interested in sales figures and commission so you will not get good advice from most of them.

Most of them have only been in the job 5 minutes and will be doing something else by next year - heaven help us all!

What make of machine shall I buy?

If you accept that after 40 years in the trade that I have got the hang of it all by now, then my advice to you is always to buy Airzone Equipment - I have worked on all different makes and Airzone would be my choice - every time.

We can or could sell about any make of compressor which we choose. We sell around 100 machines a year and no manufacturer would turn that volume of business away, some of the small manufacturers don't sell that many in total.

 How do we choose which makes to sell and not others?

We have been in the trade 40 years and used to be main distributors for several manufacturers. Our engineers are all factory trained and our spares dept is properly stocked. We also know which are the good makes and which are the pups - we know which makes are reliable and which are not - we know how different manufacturers react to warrantty problems - 99% of them are not good with warrantty issues - so be warned.

So from that experience we decide who we want to deal with and at that you can have confidence too.

A few years ago we were persuaded to sell machines for another very well known make, we sold 10 units quite quickly and had warranty problems with 8 of them - what a disaster - never again.  Needless to say that new relationship ended very quickly.
