The disc diffuser series combines cost-effective design, low installation costs, reliability and performance in intermittent and continuous aeration processes.

• Precision die-cut openings for high oxygen transfer efficiency and performance: The operating pressure can be adjusted to customer or system specification by using different slit patterns varying the number and length of the slits and the spacing between the slits
• Active diameter between 184 mm and 295 mm
• Different standard and special membrane materials specially engineered for a wide spectrum of applications:
  • EPDM: municipal wastewater
  • Low plasticizer EPDM: animal processing, food processing, beverage production
  • Silicone: pulp and paper industry, petrochemical and refining processes

All membrane materials can be equipped with an anti-fouling surface based on nanotechnology to prevent the build-up of solids and biological encrustations.

• Glass fibre reinforced polypropylene body plate and ring for maximum chemical, temperature and UV resistance
• Different orifice sizes to adapt to various airflows
• Check valve integrated into body plate, optional ball valve available
• Easy mounting on 3-inch and 4-inch IPS pipe as well as 90-mm and 110-mm diameter metric pipe of any thermoplastic material (PVC, CPVC, PP, ABS etc).
  • EPDM rubber grommet
  • Glue-on PVC saddle (for PVC only)
• Low maintenance requirements
• Standard units in stock for immediate shipment.
