The Dräger Aerotest® Simultan HP is a specialized test system designed to determine the quality of respiratory air in high-pressure applications. It enables quantitative measurements of contaminants such as carbon monoxide (CO), carbon dioxide (CO2), water vapor (H2O), and condensed oil/lubricants in breathing apparatus cylinders and compressors. These measurements can be accomplished in minutes, ensuring the safety and quality of breathing air.
Function Description
The primary function of the Dräger Aerotest Simultan HP is to provide a reliable and quick method for testing compressed air quality. It is used to detect and measure various potentially harmful substances in high-pressure air systems. The system allows for individual or simultaneous determination of contaminant concentrations, ensuring compliance with relevant standards such as the CGA G-7.1-2018 document. The core of the system relies on Dräger-Tubes®, which are well-known for their accuracy in detecting and measuring toxic gases.
A key component of the system is the Dräger Oil Impactor, specifically designed to detect oil aerosols in compressed air. This impactor is capable of measuring not only normal oils but also synthetic oils, regardless of their type or viscosity. The quantitative results from the oil impactor are easily visible through a tiered structure, simplifying the assessment of oil contamination.

Usage Features
The Dräger Aerotest Simultan HP is designed for fast and simple application. It can be connected to the high-pressure air system via the CGA-347 adapter without the need for additional tools; a simple hand tightening is sufficient. This ease of connection allows for quick setup and initiation of tests. Measurement results are typically achieved within 5 to 10 minutes, making it an efficient solution for on-site air quality checks.
The system's portability is a significant usage feature. All components are neatly arranged within a robust carrying case, ensuring that the device is always ready for use and can be easily transported to different locations where air quality testing is required. This makes it suitable for field applications, such as testing breathing air from mobile compressors or various compressed air cylinders.
The ability to quantitatively detect various potentially harmful substances, including carbon monoxide, carbon dioxide, water vapor, and oil, provides comprehensive monitoring of breathing air quality. The Dräger Oil Impactor's unique capability to measure synthetic oils, independent of their type and viscosity, broadens the scope of its application, especially in environments where different types of lubricants might be used in compressors.
Maintenance Features
While the manual does not explicitly detail maintenance features, the design of the Dräger Aerotest Simultan HP implies several aspects related to its upkeep and readiness:
- Modular Components: The system consists of individual components such as Dräger-Tubes, the oil impactor, adapters, and a pressure reducer. This modularity suggests that individual parts can be replaced as needed, rather than requiring the replacement of the entire unit. For instance, Dräger-Tubes are consumable items, and the kit includes multiple sets, indicating a straightforward replacement process.
- Sinter Filters: The inclusion of a package of Sinter Filters suggests that these are replaceable components, likely designed to protect the system from particulate matter, thereby extending the lifespan of other sensitive parts. Regular replacement of these filters would be a standard maintenance procedure.
- Tube Opener: The Dräger TO 7000 Tube Opener is provided, indicating that the Dräger-Tubes are designed for easy and safe opening, which is part of the routine preparation for each test.
- Transport Case: The robust transport case not only facilitates portability but also protects the components from damage during storage and transit, contributing to the longevity and readiness of the equipment. Proper storage in the case helps maintain the integrity of the delicate measurement instruments.
- Instruction for Use: A detailed instruction manual is included, which would guide users on proper operation, troubleshooting, and potentially basic maintenance checks, ensuring the device is used correctly and remains in good working order.
Overall, the Dräger Aerotest Simultan HP is a comprehensive, portable, and user-friendly system for ensuring the quality and safety of high-pressure breathing air, with design elements that support ease of use and practical maintenance.
