Product catalog summary

Overview: The document is a technical data sheet for the JetFlex® Disc Diffuser - HD 200 Silicone J24, produced by Jaeger Group of Companies. It provides detailed specifications, operational guidelines, and maintenance instructions for the diffuser used in municipal wastewater treatment.

Specifications:

Air Flow Rates: Standard operation ranges from 1.5 to 4 m³/h, with a maximum overload rate of 10 m³/h. Operating temperature is between 0 to 100°C.
Dimensions: The diffuser has a total diameter of 233 mm and an effective diameter of 184 mm, with a perforated area of 0.025 m².
Materials: The membrane is made of green/transparent silicone with specific mechanical properties such as tensile strength (>9 N/mm²) and elongation at break (>600%).

Installation and Maintenance:

Diffusers should be stored in a dark, dry, and ventilated space to avoid damage. Rubber parts should not be stored for more than one year before installation.
Maintenance involves using formic acid for cleaning and ensuring maximum airflow for short periods to maintain diffuser condition.

Performance:

Standard Oxygen Transfer Efficiency (SOTE): Tested under specific conditions with a water depth of 4.5 m and a temperature of 16.3°C.
Headloss: Internal tests show tolerances of +/- 5%.

Disclaimer: The document states that the information provided is based on current knowledge and does not guarantee specific product properties or suitability for particular applications.
