Oblan externally mounted dynamic air precleaners, available from Norman G Clark , consist of a steel housing with static vanes and a rust-proof rotor mounted on dual ball bearings over double-welded plate steel.

The perforated metal pre-screen at the inlet is standard. The outlet tube can be adapted with the supplied reducing sleeves for a range of outlet choices.

Oblan engine air precleaners are powder coated for a durable, corrosion resistant finish. Air flows range from 53 to 1411CFM (1.5 to 40.0 m³/min).

They are usually installed in place of the rain cap, dust bowl, or aspirated precleaner (exhaust system). In some applications, they can be mounted directly to the air cleaner.

Air enters the system through a pre-screen that removes debris. It then flows through static vanes causing the air to spin.

As the air spins, centrifugal force separates dust, dirt, insects, rain and snow from the air stream. The swirling air drives a high velocity rotor that acts as a blower evacuating contaminants through special discharge ports at the bottom or in the side of the unit.

Only purified air flows to the air filter elements. Oblan precleaners remove up to 90% of impurities from intake air before the air enters the filter element; they extend filter life up to 10 times and reduce down time by up to 50%, prolonging engine and turbocharger life.

Oblan engine air precleaners are designed to be mounted on or connected to the air filter intake of a gasoline, diesel or compressed natural gas engine air cleaner.

Oblan engine air precleaners’ applications include all slow-moving and industrial equipment such as agricultural machinery; earth moving, construction and mining equipment; pumping plants; generator sets; material handling equipment; snow removal equipment and street sweepers.
