“Genial vertikal” – the new high-pressure compressor Tornado by J.P. Sauer & Sohn
July 27th 2007

Acknowledged as a worldleader in compressor technology, Sauer has increased the product range of air-cooled high-pressure compressors with the newly designed Tornado series, consisting of the threestage WP 3215 and the four-stage WP 4325.

The Sauer Tornado series provide the following benefits:

• high-pressure performance - 225 to 400 l/min – to 420 bar

• lower operating temperatures

• low vibration

• less maintenance

The Tornado design principle is based upon the established water-cooled WP 5000 Sauer Navy compressor, as used in modern submarines, with the vertical arrangement for the running gear and the ‘star-arrangement’ for the cylinders. This design configuration is distinguished by the very small foot-print needed and, with almost perfect mass balance, for the extremely low values for airbourne noise and vibration.

Optimal results for airborne noise and inter-cooling temperatures of

the compressed air are achieved with the unique arrangement for the

high-performance axial-flow cooling fan. This design feature in a flowoptimised

housing, together with again optimal design for both intercoolers

and after-cooler, was especially developed for the Tornado series.

The low outlet temperature of 5°C above ambient, as well as a maximum 3 mg/m3 residual oil content, considerably reduce the expenditure required for downstream filtration and improve service life. Direct-drive, pressure-oil lubrication with slide bearings for the crankshaft, in conjunction with benefits from the Sauer ‘star’ cylinder design; ensure exceptionally reliability with low-maintenance operation and servicing intervals far longer than those of the competition.

Either of the Tornado compressors, WP 3215 and WP 4325, is available as a “Basic-Version” – compressor with motor and, as an option, a separate Control Panel – and as a “Comsilent-Version” – a complete, ready-to-operate system within a soundproof enclosure. In addition, both compressors can also be supplied for “special” applications if needed.
