Vert supplies highly powerful, efficient and quiet compressors capable of reaching an incredible pressure of 300 psi in a single stage. All combined in a lightweight compact package that produces virtually no vibration.
To enable highly sensitive machines such as 3D printers and CMMs, Vert supplies a 100 lpm compressor the Nautilus A100 that produces no vibration, low noise, and clean air with an integrated Class 1 filter

High-precision coordinate-measuring machines (CMM) need clean compressed air, Class 4 purity or better, preferably Class 1. Contamination of air with particles may lead to failure of air bearings in the probe head, lowered precision, expensive repair, and delay the manufacturing process.
Typically, the factory does not guarantee high air purity. Building airlines with filters and dryers may be very expensive. In this case choosing a point-of-use air compressor may be a simpler and cheaper alternative. The piston compressor is not advisable due to the high level of vibrations, which is bad for CMM precision. A rotary compressor, with a Class 1 filter is a preferred solution because it helps to prevent expensive repair and down-time.
High-value metal 3D printers are often used in engineering design houses, hospitals, laboratories, etc. Such facilities may not have a central supply of compressed air, or 3-phase power. For 3D printers, which require compressed air, a point-of-use air compressor is a preferred option. Such compressor should be very quiet, run from 1-phase mains power, and provide Class 1 air quality, to protect the 3D printer from contamination.
While piston compressors may look like a cheaper option, they produce significant vibration and high level of noise, which means that under the H&S law they may only be used for a short time. “Quiet” compressors typically operate at 50% duty cycle, such as 15 min on / 15 min off, and therefore may interrupt the work of the 3D printer.
As an example application of their highly efficient, unique and versatile conical rotary compressor design, Edinburgh-based Vert Rotors received Centre for Defence Enterprise (CDE) funding to develop a prototype system that could significantly improve the quality and resolution of infrared imaging in small surveillance satellites.
In small imaging systems vibration isn’t desirable, but it is an inherent feature of current, state-of-the-art cryocoolers based on piston compressors. Vert Rotor’s miniature low-vibration cooling system design is based on their conical rotary compressor technology developed to cool infrared image sensors on small satellites with very little vibration, thus eliminating this problem.
Vert Rotors has already started another project to upgrade their rotary cryocooling system for space simulation testing. In the future this could offer a step-change innovation for a future British space-surveillance capability.
