DualAir®

Product catalog summary

Introduction
The DualAir® Fine Bubble Diffuser System, developed by Evoqua Water Technologies, is an advanced aeration solution designed for reaction tanks. It features a unique design where two diffuser bases are molded together, allowing for efficient mounting and increased diffuser density per air header.

Design and Advantages
The DualAir system allows for up to 40 diffusers per 20-foot air header section, offering a greater contact area for a stronger bond between the diffuser assembly and piping. This design reduces the need for multiple air diffuser headers, pipe supports, and manifold connections, leading to lower shipping costs and more open floor space for maintenance. Installation time is reduced by 20-40%, making it a cost-effective solution.

Installation and Cost Efficiency
The DualAir system is economical, requiring fewer components such as air diffuser headers and support stands. It can be installed at 20-40% less cost compared to previous systems. The system's flexible design accommodates either membrane or ceramic media, secured by a threaded lock ring.

Oxygen Transfer Efficiency
The EPDM membrane media used in the DualAir diffusers is durable, lasting up to 10 years even at high airflow rates. It features precision perforated slits that resist tearing and ensure equal fine bubble distribution. Ceramic media meets or exceeds industry standards for strength and performance.

Product Range and Support
Evoqua offers a comprehensive line of fine and coarse bubble air diffusers, ensuring the right fit for any application. The company provides full technical support for air diffuser selection and aeration piping system design.

DualAir® diffuser with membrane media. Coarse Bubble Diffusers The EPDM membrane media is a high pressure injection molded compound using a well proven formula that has superior rebound memory. It will last up to 10 years, even at high airflow rates. The membrane includes precision per orated “I” slits that f resist tearing and stay cleaner, longer. They open when airflow is present, close when airflow is stopped. A thick center prevents ballooning and the unique tapered membrane cross section guarantees equal fine bubble distribution across the entire surface. When ceramic media is supplied...
