ULTRAAR SC · silent screw-compressor air plant

Quiet medical air for hospitals that need calm.
ULTRAAR SC · silent screw-compressor air plant

ULTRAAR SC: the medical air plant quiet enough for a ward.

Medical air drives ventilators, anaesthesia and surgical tools. Producing it usually means a compressor, and compressors are usually loud. In a hospital, that noise is a real problem.

When noise matters as much as flow, the machine inside is what makes the difference.

ULTRAAR SC solves it with a screw compressor at its core. Instead of a piston hammering back and forth, a screw compressor turns two meshing rotors in one continuous motion. The result is steady, oil-free air with far less noise and vibration.

That means the plant can sit closer to where the air is needed, run continuously without fatigue, and not disturb the people around it.

It still delivers clean, dry, medical-grade air to EN ISO 7396-1, around the clock.

Ultra Controlo designs and manufactures ULTRAAR in Portugal.
