Frequently Asked Questions

What are the primary applications for these aerators?

These aerators are versatile and widely used in industrial wastewater treatment, home systems, agriculture, hospitals, and various water purification processes.

What materials are used for the aeration membranes?

The membranes are typically made from high-quality EPDM or Silicone, providing excellent durability and chemical resistance.

What is the expected service life of the product?

Under standard operating conditions, these aerators are designed to have a service life of 6 years or more.

What is the standard oxygen transfer efficiency?

The fine bubble aerator models (DD215, DD270, DD330) achieve a standard oxygen transfer efficiency of ≥38% at 6m submerged depth.

What connection sizes are available for installation?

All standard models come with a 3/4" NPT Male thread connector for easy integration into existing piping systems.

How do I choose between coarse and fine bubble aerators?

Fine bubble aerators (1-2mm) are ideal for high oxygen transfer efficiency, while coarse bubble aerators (4-5mm) are often used for mixing and preventing sediment buildup.
