Ing. Enea Mattei SpA: compressed air since 1919. Azienda italiana produttrice di compressori d'aria

Over the years, Mattei has continually evolved and is today one of the world’s foremost companies in the compressed air sector and the leader in the production of rotary vane compressors. Behind the success of Mattei are the choices the company has made in terms of design, production and marketing, driven by the results of its continual and in-depth research and devlopment programmes. During these

years of continual change, Mattei has been able to adapt to the requirements of the market and through the results of its research has created products that are always innovative and technologically advanced.

The cost you can't see.

The day-one spec was met. The lifetime economics weren't.

An independent industry analysis of a single meat-processing site found that roughly 30% flow degradation in ageing screws meant about 870,000 kWh wasted per year.

In a 24/7 biogas upgrading plant, where flow is revenue, even a few percent of lost compression flow can quietly erase millions over the project's life.

You can't easily audit a running compressor's true efficiency without a calibrated test — so the bleed accumulates unnoticed, year after year.

The number that's drifting is specific energy: kW per m³/min, the true cost of every cubic metre of air.

When did you last measure yours?

It runs in, it doesn't wear out

Most machines get worse as they bed in. A rotary-vane compressor gets slightly better.

In the first ~500 hours, the blade flanks polish smooth where they slide in their rotor slots, cutting internal friction and trimming the power drawn. Efficiency rises a few percent — independently verified by Intertek — and then it locks in and holds.

(To be precise: the gain comes from the flanks polishing, not the tips. The tips never contact the stator at speed.)

At zero hours a good screw and a vane are broadly comparable. By 500 hours the vane has improved and pulled ahead — before the screw has even begun to age.

Then the two move in opposite directions, and the gap widens.

The self-renewing seal.

A rotary-vane compressor seals on a hydrodynamic oil film. The film is the seal — and it reforms on every rotation.

There's no clearance to open. The rotor carries no axial thrust; it floats on two continuously lubricated bush bearings, so there's no thrust bearing whose wear could ever open the seal.

There's no blowhole.

And the blade tips never touch the stator wall — they ride on the film. (If they touched at running speed, the surfaces would seize in an instant.)

The seal doesn't decay over time. It's renewed every revolution.

That single architectural difference is why a vane machine holds its efficiency for decades while a clearance-sealed machine declines from hour one.

Scheduled, not surprising.

Here's a tell hiding in plain sight: screw-compressor makers themselves recommend an air-end overhaul every four to six years.

That interval isn't arbitrary. It's roughly the point where lost efficiency and bearing wear make opening the machine worthwhile.

Read it honestly and it's an admission — the decline isn't a risk, it's expected, scheduled in from the day of sale.

And the uncomfortable part: an overhaul restores the geometry, but the loss returns. Independent field studies of in-service screw fleets have measured efficiency losses anywhere from 15% to over 50% against the original rating.

The wear is built into how the machine seals.

In woodworking, compressed air is involved in almost every step of the process — cutting, drying, sanding, painting, sawdust removal, and powering pneumatic tools. It's one of the most critical utilities on the shop floor, whether you run a large production facility or a small carpenter's workshop.

But here's the challenge: wood dust and residues are everywhere. And when they contaminate your compressed air system, the consequences show up where it hurts most — in your finish quality, your equipment lifespan, and your energy bill.

That's where Mattei comes in.

Our compressors for the woodworking industry are built around one goal: delivering clean, reliable, efficient air — every single day.

✔️ 99.99% oil-free air thanks to a multi-stage filtration system
✔️ 15%+ energy savings compared to other rotary compressors
✔️ Up to 100,000 hours of operation without replacing vanes or metal parts
✔️ Lowest Life Cycle Cost on the market
✔️ Compact design for easy, space-saving installation
✔️ Customized solutions for any application or environment

From the Blade 1-3 for smaller setups to the ERC 4-11 for high-demand production lines — there's a Mattei solution built for your needs.

❤️ When sport meets solidarity.

Yesterday, Mattei proudly took part in the Lega Tumori Lilt Milano Marcia Formula One 2026 at the iconic Monza Circuit, where colleagues, friends, and families came together to walk and run in support of cancer prevention.

A meaningful day of participation, awareness, and community, helping to support the valuable work carried out by LILT every day.

Thank you to everyone who joined us on the track and made this event so special. 🙌

🧑‍🎓Mattei Academy — The First Courses Have Begun!

These past weeks marked a truly exciting milestone for us: the first Mattei Academy training courses are officially underway, and the enthusiasm from our network has been incredible.

A huge thank you to all the participants, distributors, and technicians who joined us — your energy made these sessions unforgettable. And of course, to the whole team that made this happen behind the scenes. 💪

The Academy journey has just begun — and we can't wait to welcome more of you!

The blowhole

Every leakage path inside a screw compressor is a clearance — and the most stubborn one is the blowhole, the geometric gap where the two rotors mesh.

Decades of cleverer rotor profiles and tighter tolerances have shrunk it. None have closed it — it's inherent to how two meshing rotors seal.

And as the bearings wear and clearances open, it grows back. The leak you spent precision-engineering money to minimise slowly returns.

No other rotary design carries so many simultaneous leakage paths. A self-renewing oil film has no blowhole to begin with.

🤩 A milestone that's more than just a number — it's proof that there's something here worth listening to, sharing, and building together.

✨ Thank you to those who've been here from the start. Thank you to those who joined along the way.

😉 But the conversation doesn't stop here... 8.000 it's just part of the journey!
