The turbo® Zone of Maximum Protection

The industry has long recognized that the self-propelled ejective type of Precleaner, such as the turbo® Precleaner, is the most efficient method of protecting both the engine and the filter from deadly micro-abrasive dust.

In a self-propelled, or atmosphere discharged precleaner, incoming air is drawn in past stationary vanes which are specially designed to cause the incoming air to spin. As the air spins, centrifugal force caused by the spinning rotor assembly separates the dirt, dust, moisture, and other particles from the air. The cleaned air then enters the intake stack while the dirt, contaminants and dust particles are expelled, through an opening, back into the atmosphere. Only the cleaned air goes to the air filter. Probably, the most important advantages of this type of precleaner are that it requires little or no maintenance, is self cleaning and maintains a continuous air precleaning function.



However, not all precleaners are created equal. In test after test, the turbo® Precleaner has exceeded every other precleaner on the market in its ability to separate harmful micro-abrasive dust from the particles of air before they can even enter the air filter. The following chart illustrates the power of the turbo® Precleaner to separate harmful micro-abrasive dust from the air in the zone of maximum danger for engines. No other precleaner can make this claim.



Air Restriction and the turbo® Precleaner

For years, the heavy equipment industry has been concerned about air restriction caused by precleaners and the impact upon engine performance. This presents the industry a real conundrum; on the one hand you want to protect the engine and filter from micro-abrasive dust. On the other hand, you don’t want to over restrict air flow to the engine. There has to be a point at which the air filtering of the precleaner compensates for the reduced air restriction on engine performance.

You as an owner or operator of heavy equipment are probably just as concerned about engine protection as you are about air restriction. Therefore it’s important that you know some critical facts about air restriction and precleaner efficiency. First of all, all self-propelled precleaners are not designed in the same way nor do they operate in the same manner. Self-propelled precleaners vary widely in the aerodynamic design of their rotor assembly including the angle of their blades in juxtaposition to their paddles. The design angle of the blades and the power of the rotational force are a vital determiner of precleaner’s ability to filter out micro-abrasive dust before it reaches the filter.

Second, precleaners direct airflow in several different ways; top-down or bottom up. The manner in which a precleaner directs the airflow is also critically important because of the resistance caused by the re-directed air flow can impact the amount of air reaching the engine at any given time. Reduced air to the engine means reduced engine power. Bottom up air flow through the base of the unit causes the air to make a "u" turn, thereby restricting the air reaching engine. These units also need special adaptors to permit the air to enter the base, thus raising the height of the unit.

The turbo® Precleaner is the only product on the market engineered with top-down air flow. This design allows air to flow directly to the engine with significantly reduced restriction. Less restriction and more air boosts engine power. Therefore, turbo® 's top-down air flow precleaner actually lowers air resistance while maximizing the air flow for effective micro-abrasive dust elimination.



The turbo® Precleaner is the only precleaner on the market that is exclusively engineered with a top-down airflow design. Tests performed at the South West Research Institute (S.W.R.I.) under the J726 June 93 Air Cleaner Test Code illustrate how the top-down airflow design of the turbo® Precleaner maximizes filter life and engine performance while dramatically reduces air flow restriction.



The important thing to remember about engine air filtration is that micro-abrasive dust is everywhere there is air….not just in harsh environments. Since every engine in every application is vulnerable to micro-abrasive dust, it just logically follows that every engine should have a precleaner. A precleaner should not be seen as just an add-on or an additional protection, but a vital part of your engine’s air filtration system. And if you don’t have the turbo® Precleaner, you may as well have nothing at all.

If it’s not the genuine the turbo® Precleaner… it’s just a rain cap.
