ZPT-TR The T-Rex (Pre-Order)
$676.00

OUR WAITLIST IS CURRENTLY OPEN! 


We are constantly manufacturing these air scribes, but demand is exceptional for this model. The T-Rex is a very labour intensive tool to manufacture, which is why it works as well as it does. If we'd known quite how popular it would be, we might have designed it so it would be quicker to make, but then it wouldn't be the same tool that has proved so useful to the fossil preparator. So we'll stick with what we're doing, knowing we're producing the best product for you that we possibly can. 

  • Operates at very low air pressures (2.5 Bar/36 PSI)
  • Powerful, packing a real punch for its size
  • Has earned its reputation as the pyrite destroyer!

  • Range of interchangeable styli available.

  • Extremely frugal air consumption (5lpm)

  • UK Made

  • Guaranteed safe checkout


Powerful, economical and versatile. The T-Rex does all the hard work for you! Customer and professional preparator feedback is truly excellent, with many people amazed by the sheer power of this little tool and the way it ‘bites’ into the rock without bouncing back.

The ZPT-TR is a super low air consumption and low pressure air pen. It works on an impact driven system (sometimes called a pneumatic hammer) designed to deliver powerful matrix removal with an ergonomic design. 


With multiple interchangeable styli available (comes with 3mm chisel or a 3mm point with other options purchasable separately), it is truly a versatile tool that can achieve initial roughing all the way through to finishing work. It will save you TIME and MONEY on operating costs. These tools truly are the state-of-the-art technology in the fossil preparation world.

  • Great for 'sticky' and pyritic rocks

  • Supremely powerful, packing a real punch for its size

  • The LOWEST air consumption (as low as 5lpm or 0.17cfm)
  • Range of interchangeable styli (including 3mm chisel, 3mm pyrite chisel, 3mm point)
  • Nominal operating pressure of just 2.5 Bars (36 PSI)
  • Rubber coated for thermal insulation and vibratory dampening
  • Really bites into the rock, making your job easy and enjoyable
  • Built for dependability

A whole range of interchangeable styli

The interchangeable stylii (pointed tip, chisels, etc.) allow for maximum versatility as a matrix removal tool, which you can still prep with. We are also able to make custom styli on request specific to your requirements (e.g. extra long). 


Raise the pressure to 2.5 or 3 Bars with the 3mm chisel or pointed stylus and you will have the full impact force of the piston at your disposal for removing large amounts of matrix. A pyrite chisel geometry is also available, designed to cut through heavily pyritic rock. 

The forceful impacts on the piston and the lower beats per minute (as compared to higher pressure tools) provide an action that lends itself to creating microfractures and 'popping' matrix away from a fossil. 

THE ZOIC PALAEOTECH QUALITY THAT YOU KNOW AND TRUST

We manufacture each tool right here in Dorset, and take enormous pride in our workmanship. Each tool is quality controlled before it leaves our workshop. Dependability, reliability, innovation and function are at the heart of what we do. We want for our tools to see you through whatever you may throw at them, and for you to enjoy using them. We want them to be quiet, comfortable and a real pleasure to use. Your satisfaction means everything to us, and if you are not satisfied, we want to know about it.


We design our tools to be low maintenance, requiring very little user input. If you look after your tools, they will look after you! When you buy from us, we want you to know that you will always have the best service we can give you. Being unique products, it is important that you know we will be on hand for many decades to come with a full supply of spares.

The ZPT-TR is a impact-driven design using an internal piston which reciprocates within a cylinder. This design does not use any springs for the return stroke and so the required air volume and input pressure are lower than the pusher-plate designs. This piston, at one end of its stroke, hits the anvil to which the stylus is attached and which is supported between o-rings ensuring oprtimal transmission of the impact force to the matrix.


The pressure can be adjusted at the point where you plug in the tool using the pressure regulator, circumventing the need to adjust it at the compressor itself. This means you can have all your tools plugged in and operating at their normal running pressure at the same time as running the T-Rex.


Customer and professional preparator feedback is truly excellent, with many people amazed by the sheer power of this little tool and the way it ‘bites’ into the rock without bouncing back. The T-Rex truly is our pride and joy. 


Packaged in a wooden presentation box. Box includes: 3mm tungsten carbide point stylus or 3mm tungsten carbide chisel stylus, 3 spare stylus O-rings, 1 spare anvil O-ring, pressure regulator, silicone o-ring grease, tool oil, inline air filter, 2m polyurethane hose (or upgrade to 2m flexible braided hose), user manual, 1x protective scribe sleeve.


We often get asked how the tools run at such low pressures, and why can't you just run the T-Rex at higher pressures like normal air pens (6 Bar/90 PSI)? The T-Rex is incredibly powerful, and should it be raised to operating at 90 PSI or 6 Bars, the impact energy would be so enormous that it would most likely shatter the tungsten carbide stylus. For instance, the T-Rex running at 2.5 Bars (36 PSI) is probably 3-5x more powerful than the ZPT-CP or the ZOIC Chicago (modified CP 9361) running at 6 Bars (90 PSI).

We've used a variety of air tools for trimming and prepping fluorite specimens from our mine at Greenlaws - in Weardale. Tried this at Bakewell show last year, and finally got it after a long wait. It's a beast - the power that it has is enough to cut through flinty ironstone, which other air tools just seem to bounce off. The great thing about it is that the same power when applied lightly to very delicate fluorite is so controllable that I can gently ease broken crystals free of the matrix without shattering anything around them. I've cut down some big blocks with the sawbench and slotted out matrix which this just pulverises - we can remove kilograms of rock very quickly without introducing a lot of vibration and introducing cracks to the matrix. It does seem to have made my other tools almost redundant. Could do with a much longer hose as standard - I'll get a reel of air hose and make one. Haven't tried the flat chisel yet - using the curved one and very happy with the finish - it flakes rock rather than pulverising, so done carefully, you can't see chisel marks on the specimen when finished.. Great piece of kit guys!

I purchased the trex pen to work Alongisde my existing air scribes, i knew it would be very useful for Matrix removal but i was so blown away by just how amazing it would be. It took me a few days to get use to it properly but now i cant see myself prepping with it. Some materials i work With include very hard stuff from Yorkshire and what would take me hours with my Old scribes takes me a fraction of the time now which in return means im actually preparing more fossils then ever to a higher standard as im not getting complacent. Just orderd the zoic chicago to compliment my preperation tools and very much look forward to a long and beneficial relationship with the team at zoic. The customer care is second to none and reply to all Messages and emails and have a real human feel interaction so you know your actually talking to a person and not a generic robot. Thanks team zoic and i look very much forward to Meeting you next year.

Huge power range, huge stylii choice (quality of stylii is exceptional as well), low air consumption, quality build, great customer service, low maintenance, comfortable, powerful, precise. What’s not to like! I love the pyrite stylii on this scribe and ideal for Yorkshire fossils.

Having used airpens for nearly 25 years now we are VERY impressed with this model , firstly the low air consumption is a real plus and the ability to remove large amounts of hard matrix in a short space of time is excellent. We have used the pointed stylus most and it really punches through the toughest matrix easily and effectively. We have used it on tough pyrite skinned concretions, hard calcareous sandstone and mudstone and the power of this pen is evident . We operate the pen within its tolerance limits and compared to other models it is very quiet too. Another plus of low air consumption is you can easily use this pen with others at the same time if you have a powerful enough compressor, we have a 100 litre one and it is not overstretched at all. For those looking for an airpen that is easy to use, operates extremely well at low pressure and can remove large amounts of matrix easily then we would recommend this model . Customer service is also excellent and queries were answered very quickly too . The T Rex is a pleasure to use.

Powerful and durable on all kinds of matrix with this professional Air Scribe. Satisfying watching the matrix just peel away. Outstanding customer support from a very knowledgeable team. For Air Prepping Tools, this company is miles ahead and there really is no other company anywhere near as good.

I have recently bought the T-rex pen to add to my tools. I needed a more powerful one to take out a bigger amount off rock and it did just, what I asked for ! The 2 different tips make for a more versatile pen that can work on almost any work. Overall this is really great tool to add to any workshop that already has a more precise tool. The customer service was extremely good and vert fast ! I recommend this tool at 100%

This air pen has the strength to remove all stubborn matrix and at the same time hold it back for finesse. Built of the best materials available to man and followed up with knowledge and experience of the company experts. The tips are made from the best metal you can buy and so far I have had no problems at all with any of my six pens. Believe me these products are worth the money. But it doesn’t end there with the knowledge and expertise, have a look in there internet shop, there is everything for the fossil collector.

Having cut my teeth and used Chicago Air Pens for several years I had the pleasure of trying out a friends ZPTR T Rex pen, and I was so impressed I bought one myself ! The difference is astounding, whilst my trusty CP 9361 has always been my go to matrix remover, when compared to the T Rex, it is like comparing a Bobcat Mini to Bulldozer, it literally eats trough the matrix, in my case the last few cm's of several Kg of extremely consolidated Middle Oxford Clay on the back of a very large Ammonite, which needed a little more finesse than a hammer and chisel, and more oomph than the Chicago could provide. When it come to air consumption the T Rex is in a different league, my Orazio Low Noise 45l Compressor barely kicks in, about a 4 times in an 1 hrs use, unlike the Chicago which can leave me stopping and starting. A highly recommended Air Pen and backed up with an excellent customer service !

What can I say, WOW! Such a powerful but versatile pen. Turned up to full power it absolutely eats matrix and that includes Pyrite. We only collect Yorkshire material which is particularly hard and this tool is more than up to the task. Dial the power down and with practice you can comfortably fully prepare ammonites and bone. But wait, it gets even better...it uses so little air I sometimes wonder if if I've forgotten to turn the compressor on. I can honestly say that this tool has has halved our preparation time and can wholeheartedly recommend it. After sales service and access to spares is second to none. If you only ever buy one pen then the T-Rex has to be a serious contender.
