Below you will find a comparison of the features of the Ful-Pak™ and the Sahara™ compressors which you can use to determine which one is right for your application.
Ful-Vane simplicity:
• field repairable
• three moving parts
• rotor
• 2-bearings - b-10 life avg. 50,0000 hours
• b-3000 blades
• abrasion &high temperature resistant
• 1-2 hour replacement time
• cost <10% of total compressor price
• replacement every 2-4 years
Ful-Vane - durability:
• designed for dusty and corrosive applications
• no special protective enclosure required
• standard 40 wt. oil used (no special oil required)
• no oil separation required
Ful-Vane - reliability:
• low speeds - reduced wear - 800 rpm max.
• air & gas applications
• average compressor life 25+ years
• proven design since 1926
Ful-Vane - low life cycle costs:
• 40% to 50% less maintenance cost than screw designs (for air applications)
Screw compressor - more complex:
• factory authorized repair only
• many moving parts:
• male & female rotors
• 6-10 bearings
• timing gears
• replacement of air-end (not in the field.)
• not abrasion resistant
• up to 60% of the cost of new compressor
• four man days replacement time in a shop
• air -end replacement inventory required
Screw compressor - Clean environment requirement:
• requires a clean compressor room
• a special dust and corrosive free environment
• special lubricants required
Screw compressor - Decreasing efficiency with wear:
• high speeds - 1000's of rpm
• vacuum and pressure applications
• average compressor life 7-8 years
• developed in 1960's
Higher life cycle costs:
• 40% to 50% greater maintenance cost than ful-vane
