Crank Case Ventilaton - Alfdex
Separation Efficiency >98% up to and including 160 l/min (42 US gal). Power Consumption 30-70 W or 400-700 l/h (106-185 US gal/h) hydraulic power (depending on driving conditions). Blow-by Gas Flow Rate Nominally 160 l/min (42 US gal) (total range 0-500 l/min (0-132 gal) with varying efficiency). Temperature Range -40°C to +125°C (-40°F to +257°F), peak +140°C (+284°F) up to 5% service life. Internal Pressure Drop None (there is a small amount of controlled suction to extract gases from the crankcase). Pressure Control An internal pressure control valves ensures that the crankcase pressure is kept within the specified range. Service Life Designed for a service life L10 of 1,200,000 km (750,000 miles) or 20,000 hours or 8 years, whichever comes first. Weight Approx. 2.4 kg (5.3 lb). Varies according to the specific engine block interface used.
The Alfdex ® Oil Mist Separator breaks new ground for crankcase ventilation on the future's diesel engines by eliminating oil and soot from the blow-by. The Alfdex separator, sealed for life, keeps turbochargers and intercoolers running at peak performance, yet require no maintenance or service.
