FARR Cyclone Dust Collectors/Separators

Advantages
• Stable pressure drop for a given gas flow
• Constant efficiency for a given particulate condition
• No moving parts; no replaceable filters
• Ability to handle extremely high dust concentration
• High temperature capability

Efficiency
On Industrial Coarse Particulate FD Cyclones are 95% to 98% efficient. Efficiency is a function of the physical parameters of the application and the design parameters of the cyclone. Cyclone efficiency increases with:

• Coarse particle size distribution
• Higher product specific gravity
• Lower gas density
• A decrease in cyclone diameter (two smaller cyclones in parallel will have a higher efficiency than one larger cyclone with an equal pressure drop)
• Smaller outlet diameter. An increase in pressure drop also results.

Efficiency and pressure drop are also affected by barrel length, outlet length, inlet configuration, and design of the internal cone. These factors are optimized to result in the maximum possible efficiency at a practical overal size and pressure drop.

Two Standard Models
The FD-45 Series is designed for economical first costs and low pressure drop. The FD-85 Series is "tuned" for higher efficiency. For a given gas flow it is physically larger and may possibly have a higher pressure drop.
