Air is necessary for successful combustion in your engine. In fact, for efficient combustion, a modern diesel engine requires several thousand times as much air as it does fuel. Clean air — air almost 100% pure — is critical to engine survival and vital to its performance.

If you add a turbocharger to your engine, you may need to make changes to the intake ducting. Turbocharged engines require even more free-flowing clean air, 750 cubic feet per minute (21 cubic meters per minute) or more. Naturally aspirated engines demand about 20% less, but still these engines can require up to 15,000 gallons (67,000 liters) of air for every gallon (liter) of fuel.

In either case the induction system (ducting, hoses and reducers) brings outside air to the engine.

  • The system should have enough intake capacity to meet engine requirements for air flow, avoiding sharp bends or constrictive ducting.
  • It should be installed in a clean location, away from exhaust flow, road grime and splash.
  • It should be vented to remove airborne moisture.
    Air may flow into the engine through a series of


  • an air-inlet hood to eliminate moisture.
  • a pre-cleaner that will typically remove 80% to 90% of all airborne contaminants.
  • an air filter housing.
  • an ancillary transfer ducting. 

The Basis of Air Filtration

Three factors determine the proper size of the air filter to be installed:

  • the amount of air flow required for efficient combustion.
  • the amount of restriction (resistance to air flow) caused by the filter.
  • the amount of dirt the filter will need to hold to allow for a reasonable change interval.

    Nearly all filters use pleated cellulose (paper) media. Different formulations of cellulose, resins and chemical additives meet specialized needs for nonflammability, for example, or for moisture resistance. The pleats in Baldwin air filters are strong, precisely separated and stabilized.

    Baldwin uses two proven methods to separate and stabilize its pleated media.

  • PermaPleat® — an embossing process that builds dividers between pleats to prevent bunching and to insure uniform air flow.
  • Beading — a continuous bead of adhesive around the circumference of the filter's metal wrap, either inner or outer, locking the pleat tips in place and preventing movement.

    Most engine manufacturers specify minimum initial efficiency of at least 98.5%. On first reading, this figure seems very high. Remember though, that dirt in any amount can be harmful to your engine.
