Clean Air for Hard-Working Engines
Oblan dynamic pre-cleaners spin dust, dirt, insects, rain and snow out of an engine’s intake air before it reaches the air filter – so filters last longer and the engine breathes clean air on the dustiest sites. Norman G Clark supplies the full Oblan range in Australia, with the elbows, adaptors and hoses to fit them.

How it works
How a Dynamic Pre-Cleaner Works
There are no filters to clog in the pre-cleaner itself – it uses the engine’s own airflow to separate the dirt.
Spin the Dirt Out
Air enters through fixed static vanes that set it spinning. Centrifugal force throws dust, dirt, insects, rain and snow to the outside of the air stream.
Powered by the Airflow
The swirling air turns a high-speed rotor that acts as a blower, pushing the dirt out through discharge ports in the side of the unit. No electrics and no exhaust connection are needed – the pre-cleaner powers and cleans itself.
Clean Air to the Filter
Only cleaned air goes on to the air filter. Oblan pre-cleaners remove up to 90% of the impurities before they reach it, so the filter lasts up to ten times longer. In the C and KL housings the air then passes a primary and a safety element that hold back 99.9% of what is left.
Why Oblan

Up to 90% Removed
Up to 90% of dust and debris is taken out before the air reaches the filter.
Filters Last Longer

Saves Fuel
A cleaner filter restricts the engine less – fuel savings of up to 10%.
Nothing to Power
Self-powered and self-cleaning; steel housings, powder coated, with the rotor on twin ball bearings.
