Sperre HL2/77
The Sperre HL2/77 is an air-cooled, two-stage 90° V- air compressor equipped with a high-capacity cooling fan. The compressor and motor come mounted on a sturdy bedplate and are linked via a heavy-duty flexible coupling. It features splash-lubricated bearings and cylinder walls, a sight glass for oil level inspection, and components approved by classification societies. The unit supports either direct bolting to the foundation or flexible installation using resilient mountings underneath the bedplate.
