Applications
Portable X-ray machines of the Keleket JD-AS type were used in hospitals, clinics, and diagnostic imaging facilities for general-purpose radiography — chest films, extremity studies, and bedside imaging where a fixed room was unavailable or impractical. Continental X-Ray Corporation was a major American manufacturer of medical radiographic equipment in the mid-20th century, and the Keleket brand was well-known in the clinical X-ray market from the 1940s through the 1960s. The Machlett Dynamax rotating-anode tube was one of the most widely used diagnostic X-ray tubes of its era, produced by Machlett Laboratories Inc. (a subsidiary of Raytheon). Units like this are now primarily of interest to medical history collectors, museum displays, radiologic technology training programs, and film/theatrical prop use. Active clinical deployment of equipment of this age and unknown functional status is not appropriate without full inspection, servicing, and regulatory compliance review by a qualified medical physicist and biomedical engineer.
This Keleket Continental X-Ray JD-AS Portable X-Ray Machine is being sold as-is, with no warranty or guarantee of functionality. RecycledGoods does not service, repair, or refurbish medical equipment. The unit appears complete with its control console, articulating tube arm, and Machlett Dynamax X-ray tube head (Serial No. K41517). The console shows significant age-related wear including handwritten notations on the front panel and surface patina consistent with a vintage instrument of this era. The tube arm and column are intact. Because this is ionizing radiation equipment requiring specialized handling, special packaging and transport are required — please contact us before purchasing to discuss shipping arrangements. Please view our photo set and contact us if you have any questions.
