Sand removal & filter protection
SandSep is a protection of GAS TURBINE and ENGINE ROOM air intakes against the undesired ingress of flying sand in desert climates or in a marine environment that is exposed to sand storms.
Airborne sand particles plug coarse filters within minutes, causing physical damage to the filters or causing a complete exchange. Under harsh conditions the amount of sand often exceeds 100 kg/m²h. Depending on the prevailing weather conditions, dust storms can be present for only a couple of days per month.

Separation mechanism
1) Incoming sand-laden air enters into the swirl and is set under rotation.
2) Sand particles are moved to the outer surface by centrifugal forces.
3) The sand particles are discharged through a ring-gap while clean air can flow out through the inner pipe.
