The JDK features a unique construction and advanced materials that deliver significantly lower operating temperatures, extending the life of the unit and protecting long-term performance. Its diaphragms remain “comfortable” at these lower temperatures, holding rated air output far longer than many competing brands that can lose small percentages of performance within hours and up to 20% within 12 months. Specifically designed for Australian installations particularly sprawling, low-set colonial and ranch-style homes that require deeper pump placement—the JDK-80 ensures strong, reliable airflow at depth while consistently maintaining the desired air output.
