The Loosco Egg Regulator: A Pioneering Innovation in Diving
The Loosco Egg regulator by Loos & Co emerged as a groundbreaking piece of diving equipment. First introduced in 1957, this unique regulator set new standards for underwater technology and became highly valued by divers.
The Origins of Loos & Co
Founded in Amsterdam in 1890 by Goossen Leendert Loos, Loos & Co initially specialized in gas for mineral water, which later evolved into oxygen production. In 1938, the company rebranded as G.L. Loos & Co’s Fabrieken N.V., known simply as Loosco.
Innovation by Jan van Buuren and Gilrath
After World War II, Dutch engineer Jan van Buuren, with guidance from his mentor Gilrath, began developing pressure regulators. These regulators found applications in both underwater and medical fields. Recognizing the potential for underwater breathing devices, Loos & Co tasked van Buuren with creating a specialized regulator. This led to the development of the Loosco Egg, the first twin-stage double hose regulator for the Dutch market.
Features of the Loosco Egg
The Loosco Egg excelled with its compensated valve system, maintaining performance even at depths of up to 150 meters. Extensive testing by the French Navy confirmed its capabilities. Unlike single-stage models of its time, the Loosco Egg introduced a balanced high-pressure seat system, providing improved cold-water performance and preventing icing.
Variations of the Loosco Egg Regulator
The Loosco Egg came in three versions:
- V1: Designed for professional diving, with roller thread hose connections.
- V2: Offered direct attachments and an upgraded mouthpiece.
- V3: Simplified hose connections by removing screw caps.
Each version retained the regulator’s core reliability and efficiency, suiting different diving needs.
Legacy and Impact of the Loosco Egg
The Loosco Egg regulator remained in production until 1975, widely used by Dutch military and professional divers into the 1980s. Although Loos & Co faced competition from brands like La Spirotechnique, van Buuren’s valve design continues to influence modern medical equipment with its low maintenance and durability.
The Shallow Water Loosco Egg
In addition to the standard model, Loos & Co produced a compact version for shallow water. Often discarded after use, this rare model is prized by collectors for its historical significance.
