Caps are most commonly used in aerobic digesters and equalization tanks where high rate oxygen transfer efficiency is not required, They are manufactured from black Acetyl plastic containing UV protection and membranes are made from the same EPDM compound that SSI uses in fine bubble disc diffusers. Caps have a3/4" MNPT thread. SSI's Cap diffuser is a non-clog design and operates well under intermittent and continuous conditions. A typical piping system utilizing SSI AFC75diffusers is made from PVC, CPVC or Stainless Steel pipe, with Grommets, Drilled and Tapped pipe, or welded¾"FNPT SS bosses to the top center line.
SSI manufactures disc diffusers and coarse bubble diffusers, and we mount these products on a wide range of piping materials including PVC, CPVC, PP and Stainless Steel. We have the ability to attach diffusers to pipe using saddles, grommets, or pre-assembled PODS. We can provide retrievable systems or fixed grids, and systems in kit form or mostly factory assembled. We try to understand and anticipate your needs, and fit our recommendations to your situation.

SSI's patented PTFE membrane barrier properties not only reduce plasticizer extraction, shrinking, and membrane hardening but also limit dynamic changes that can result from swell, such as creep. Compared with uncoated products that are more susceptible to increases in DWP due to more aggressive fouling and changes in physical properties and weight, the PTFE coated membrane improves consistency of DWP (Headloss) values over the product life. This directly impacts long-term power costs and the ability of the system to distribute air uniformly across the tank floor.

The Cap diffuser units are furnished completely factory assembled. The only work required by the Contractor is the installation and placement of the diffuser units on the laterals piping.
Diffusers utilize rubber membranes as the air diffusion media. Alternate membrane materials are available for special applications.
SSI recommends care in handling and storage to prevent tearing, puncturing or fouling of the rubber membranes. If units are to be stored before installation, SSI recommends utilizing the original unopened shipping cartons. Store in a clean, cool location that avoids potential mechanical damage
Air distribution through the diffuser is a function of the individual diffuser elevation. For proper system operation, SSI recommends a leveling tolerance of ± 3/8" for the diffuser unit. If the diffusers are mounted with excessive elevation tolerances, the airflow distribution in the system will be adversely impacted.
