Great Products Begin with Great Design

Before you can create a great product you need a great design and our Ztechnique design team have been hard at work producing our range of Ztechnique replacement air ends for Atlas Copco Z compressors..

Take a look at our casting design

Take a peek inside the stage 1 design showing the compression chamber, oil seal and bearing locations, port to atmosphere, water channels and oil feeds.

We use this type of casting for training and customer visits to show the quality of our castings etc .

Moulds are made for the Ztechnique castings

Using the latest techniques our moulds are made ffrom our own design.

New Castings are used in our Ztechnique air end products

The Importance of NO donor parts is paramount to the quality and one way shipping to far of customers around the World.

No need to return your old broken element with NEW Ztechnique brand products and NO Non Return Charges levied

Quality Testing of all our Ztechnique parts

New Ztechnique element castings are tested before and after CNC machining for quality. Several castings from our production line are cut apart to check for the correct casting process being maintained.

New Timing Gears used in all our elements

The Importance of the timing gears being new cannot be ignored..

The precise clearance between the coated rotors is maintained by the timing gears and after long periods of running 80,000 hours or more the gears are 'run in' and must be replaced. Our NEW Ztechnique elements have NEW gear sets from the onset made from high grade materials and quality checked for precision in use

Ztechnique Rotor Cutting

Rotor billets are aligned from high grade steel ready for machining

Rotor Cutting takes place

Using our own profile the cutting machine works hard to make the male and female rotor sets

Balancing Rotors

its essential after machining and our rotor coating is applied that the the rotors are checked for balance and adjusted as required for a the lowest possible vibration in use.

Seals and Bearings

Our seal assembly's are carefully selected for quality for containing the oil completely away from the compression chamber and ensuring 100% oil free air is produced. The sealing methods are very reliable combined with our journal coating procedures

Wave Springs and Assembly

4 Point Bearings are used in our NEW Ztechnique Elements

High Quality European manufactured bearings are used in the assembly of our Ztechnique elements with the cut out sections providing assess for bearing and gear lubrication.

the high speeds at which the rotors turn requires a high grade bearing to cope with the stresses

Rotor Coating Procedures

Applying the rotor coating is a multi step process with each step applied in a controlled spraying method baked at differing temperatures cycles to ensure correct bonding.
The purpose of the coating is two fold, minimising rotor clearances and protection from moist atmospheres and corrosion of the rotors etc . Ztechnique uses several coatings dependant on the application.

We have ensured over thousands of hours run that our coating offers maximum protection..

Rotor clearance checks are carried out

Before and after rotor coating we check the clearances of our male and female rotors.

Correct meshing of the rotors and tolerance checks is essential for the correct performance of the elements Ztechnique produce.

Ztechnique Element Assembly begins

At every stage we check alignments and ensure tolerances are met for all aspects of the Ztechnique elements

Rotor Meshing & Coating the screws

Here you can see the specially coated male and female rotors meshing inside the casting after assembly. our coating has been applied to the rotors and we carefully ensure that no contact is made between the rotors with NEW cut timing gears.

Nothing is re used on the Ztechnique elements we produce they are all NEW and at great prices compared to OEM RRP

Checking the element assembly Ztechnique

We dry assemble the element first to check all mating surfaces are perfect before bearings and seals are installed in the castings and on our rotors..

Each Ztechnique element has to fulfil a list of assembly checks before it can be transferred from our assembly centre to the TEST Centre where the element is run for 2 hours to ensure that a high quality product reaches the customer..

Element Test Centre

Our new test centre ensures each air end is tested for output &pressure targets whist being tested for vibration SPM and seals performance. At this stage any flaw in assembly will show itself to our test engineer and will result in rejection unless the Ztechnique element meets our targets for performance

100% Oil Free Air Testing

We are able to test your air quality post Z compressor overhaul with a Quality Air test to British Standards.

ISO 8573 Air Testing
The ISO 8573 standard consists of purity classes for contaminants in compressed air: particles, water, and oil. In addition, ISO 8573-1:2010 also identifies microbiological contaminants. The ISO 8573 purity classes can be used to describe the quality of a compressed air system or to specify the required quality for a precise application. Compressed air specifications should meet product performance requirements.

To be sure your air is 100% oil free from our Ztechnique Elements this additional service is available...

Test Certificate Ztechnique Elements

After testing the element gets a full identity test cert provided showing the data recorded and your test engineers signature. For warranty purposes you must keep this certificate

Packaging and Protection in Transport

After testing each element is rust protected and tape applied to ensure no contamination or entry of foreign objects can take place before the element reaches its destination address

Each air end is stamped with a unique serial number for ztechnique warranty

Each Element is delivered with a USB stick loaded with your elements data

With Each Air End supplied you get a Ztechnique Branded USB stick with your elements documents and Instructions on both video and PDF of the correct pinion fitting Instructions

We also Include a ZR ZT ZE ZA commissioning sheets so as you can send the relevant data on the re commissioned compressor back to Air Hire data centre for future warranty purposes

High Quality Branded Packaging

High Quality crates are used to ensure no transit damage can occur and each element is accompanied with its TEST Certificate and pinion install Instructions

Our crates can be re-used once for any warranty returns

Stock Holding Ztechnique Elements

Our large stockholding of refurbished and new ztechnique elements ensures that when you need your Z service stage quickly Air Hire can deliver..

We ship right around the World to more than 34 country's in 2013 and with our targets for export increasing we hope to sell our elements to even more customers in 2014
