Hitachi DSP Series – Oil Free Rotary Screw Compressors 30 to 300 hp (22-240 kW)

The EXAIR ultrasonic leak detector is a compact and highly sensitive inspection device designed to help industrial facilities identify costly compressed air leaks and improve overall system efficiency. Using advanced EXAIR air leak detection technology, this portable instrument detects ultrasonic sound waves generated by escaping gases and converts them into audible frequencies that operators can hear clearly through headphones. Compressed air systems are essential in many manufacturing and industrial facilities, but hidden leaks can significantly increase operating costs and energy consumption. In some plants, air leaks can account for up to 30% of total compressed air usage. Even small leaks can force compressors to work harder, increasing electricity consumption, equipment wear, and maintenance expenses. Implementing reliable EXAIR ultrasonic leak detection solutions allows maintenance teams to quickly identify and repair leaks before they impact productivity and system performance. The Ultrasonic Leak Detector is specifically engineered for industrial environments where traditional leak detection methods may not be effective due to high background noise levels. Because ultrasonic sound travels directionally, operators can easily pinpoint the exact location of a leak by following the sound intensity and LED indicators displayed on the unit. This makes inspections faster, safer, and more accurate. Understanding how ultrasonic leak detectors work EXAIR can help facilities improve preventive maintenance programs and reduce unnecessary energy waste. When compressed air or gas escapes from a pressurized system into a low-pressure environment, turbulence is created. This turbulence generates ultrasonic sound waves that are above the normal range of human hearing. The detector captures these ultrasonic frequencies and converts them into lower audible sounds that can be monitored through the included headphones. In addition to compressed air systems, the detector can also be used to locate vacuum leaks, refrigerant gas leaks, steam leaks, electrical arcing, and mechanical wear issues. The portable design and adjustable sensitivity control allow maintenance personnel to perform inspections quickly across multiple plant areas without interrupting production. Facilities using ultrasonic leak detection systems EXAIR can improve equipment reliability, reduce compressor load, extend equipment life, and lower overall operating costs. The rugged carrying case, lightweight construction, and included accessories make the detector ideal for daily industrial maintenance and energy-saving programs.
