filter for higher air mass flow due to turbocharger

and higher dust holding capacity. Initial restriction

180 mm of H20.

General

Air filter serves to filter dust from intake air for the

engine. The air filter on the Safari DICOR is dry type.

This also serves to dampen intake air noise. In

addition to dust separation, the filter has a high

dust holding capacity.

Operation

In dry type air filter the air flows into air filter

chamber due to suction pressure. The dust is

separated by the filter cartridge and clean and dust

free air is sucked in the engine.

Maintenance

A service indicator is fitted on the filter outlet which

indicates high pressure drop due to dust

accumulation. This indicator is to be checked during

servicing after specified kms. If the red band

appears then the cartridge should be cleaned with

pressurized air. The cartridge to be replaced after

specified kms.

Choked air filter cartridge causes

1. Increased wear of piston and cylinder bore.
