The United Conveyor Corporation (UCC) Ceramic-Lined Fly Ash Diffuser Feeder (FAD) is designed to provide extended service life in high capacity / high wear pneumatic conveying applications. This single-piece, ceramic-lined feeder offers superior performance, lower lifecycle cost, and reduced maintenace in severe duty applications compared with DURITE® or ceramic-tiled constructions.
■ Body Material: Gray Iron
■ Lining Material: Single-Piece, Silicon Carbide Ceramic
■ Valve Opening: 90°, Full Quarter Turn
■ Longer Service Life
› Single piece, mechanically secured, silicon carbide ceramic liner eliminates grout/adhesive failures
› 90° valve opening reduces wear damage
› DURITE or optional tungsten carbide disc and seat provide superior wear resistance
› Greased sleeve bearing for greater load capacity and improved shaft support
› Cylinder bracket redesigned for more reliable support
■ Superior Sealing Performance
› Spring loaded packing design maintains consistent seal pressure during operation, preventing leakage and extending service life
› Larger actuator provides greater force to seal and open against pressure
› Redesigned seals and bearings provide a simplified seal over roller bearing designs
■ Simple and Fast Installation
› Drop-in replacement with standard UCC FAD for easy performance upgrade
■ Reduced Maintenance
› Enlarged cover and opening for easy access to seat and disc
Will the Ceramic Lined FAD fit in place of my existing diffuser feeders?[+]
Yes, it is a direct fit for older FAD’s using the same connections.
Why is the Ceramic Lined FAD better than alternative ceramic lined options?[+]
The single piece, mechanically retained ceramic liner is user replaceable and does not depend on epoxy or grout which have temperature limitations and are not field serviceable.
Do I need a new actuator and solenoid air valve with the SiC Lined FAD?[+]
That will depend on the existing solenoid air valve. A 4” air cylinder is now the standard actuator. It has a longer stroke than previous 4” cylinders due to the increased disc actuation. If the existing solenoid air valve is a ½”, 4-way valve, it can be reused.
