1. DESCRIPTION

Subtask 21-58-01-870-001-A00

A. Description

The E/E Cooling Centrisep® Air Cleaner (see Figure 1) is a high efficiency, self-scavenging

device designed to protect the E/E Cooling System from the ingression of particulate

contamination.

A. Operation

1) The E/E Cooling Centrisep® Air Cleaner consists of individual Centrisep® air cleaner

tubes arranged in parallel to provide high flow capacity and low-pressure drop. Each

inlet tube has a fixed vortex generator. Contaminated air entering the Centrisep® Air

Cleaner tube is given a swirling motion induced by the vortex generator. This swirling

motion causes the heavier dirt particles and water droplets to be thrown radically

outward by centrifugal force toward the wall of the inlet tube where they are scavenged

overboard with a small portion of the inlet air. Clean air located at the eye of the vortex

generator proceeds straight through the outlet tube. Thus, clean air is delivered and dirt

and water are continuously removed.

2) Within the aircraft, purge (scavenge) flow is provided by the lavatory/galley exhaust vent

system.
