Possibly the smallest, quietest air compressor on the planet...

From the SCR stable of state-of-the-art air compressors comes the new 'Permanent Magnet' range. Priced advantageously in the market-place, they are ideally suited to piston-type air compressor applications. Quiet, vsd controlled, portable and low maintenance, the profile of the 'Permanent Magnet' series incorporates ease-of-use with maximum efficiency. Occupying a smaller footprint than their counterparts they are 10% more efficient, and operate with a motor efficiency even higher than IE3 premium efficiency. Available now! Want more information on the new range? See the PM series technical specifications - or read about the new PMR range of compressors (permanent magnet receiver mounted air compressors) - affordable excellence and outstanding performance.

Benefits of the range include:

advantages of a permanent magnet air compressorA high efficiency air end. The asymmetric rotor profile allows for a broader sealing band between rotors compared to the conventional narrow style. This can increase efficiency by as much as 5-10%. Triple lip shaft sealings, combined with an oil recovery system, ensure that the design is leak-free and immune to dust ingress & oil or air loss.

A special dual housing oil-cooled motor. The air end lubricant also cools the motor in a design in which the two housings are incorporated into one, with space left for an oil channel between the inner & outer housing.

A uniquely designed permanent magnet motor. With a higher efficiency rating than even the industry bench-mark of IE3, the PM motor offers both grease and bearing-free maintenance. Compact in design & quiet in operation it provides minimal levels of vibration.

Vector control technology. The PM vsds uses feedback from the motor to calculate the exact voltage & frequency required - thus ensuring optimal efficiency & torque over an ever-changing wide range of speeds.

A high-flow, leak-proof design. Rigid steel piping (with high-flow characteristics) eliminates oil pressure losses and the risk of rupture or oil loss through the normal ageing of traditional flexible, rubber hoses. All joints in the hoses employ a combination of fluorine o-ring & compression rings to offer a leak-free and vibration free operation.
