EDI FlexAir® PermaCap?

Product catalog summary

Product Overview: The EDI FlexAir® PermaCap™ Coarse Bubble Diffuser Unit is designed for aeration applications requiring intermittent coarse bubble operation. It offers greater unit capacity at a lower cost compared to other small diameter diaphragm coarse bubble diffusers.

Key Features:

Low capital and maintenance cost.
5-inch diameter for enhanced air distribution.
Engineered air outlet orifices and non-clog design.
Durable ABS body and membrane retainer ring.
Available with 3/8 inch or 3/4 inch NPT (male) connection.
UV protection and advanced technology EPDM membrane.
Internal check valve to prevent solids entry into piping.
Promotes fluid interaction with maximum bubble formation and dispersion.
Preferred mounting on the bottom of air piping.
High airflow capacity.

Design and Construction: The diffuser assembly includes a flexible membrane element that excludes solids during idle operations, ensuring long-term trouble-free operation. The membrane retracts and seals the air exit port during idle operation to reduce backflow.

Installation and Compatibility: Suitable for installation on the bottom of diffuser piping, the PermaCap units are ideal for single drop pipe installations in package treatment plants and channel aeration. Optional UDM is available for non-threaded applications.

Performance Specifications:

Diffuser Type: Coarse, Medium, Fine.
Design Airflow: 2-20 scfm for coarse, 1-8.0 scfm for medium, 0.5-2.0 scfm for fine.
Overall Diameter: 5.00 inches (127 mm).
Active Surface Area: 0.13 ft² (0.012 m²).
Dry Weight: 0.19 lb (0.087 kg) for 3/8" orifice, 0.20 lb (0.091 kg) for 3/4" orifice.
Net Operating Buoyancy: 0.040 lb (0.018 kg) for 3/8" orifice, 0.049 lb (0.022 kg) for 3/4" orifice.

Operational Recommendations: Optimum oxygen transfer efficiency is achieved when operating in the middle to low end of the airflow range. The approximate operating pressure at mid-range is 5-10 inches (1.2-2.5 kPa).
