5.5 Compressor Replacement
The compressor is the “pump” within the oxygen concentrator that pushes room
air into the bottom of the sieve beds. This allows oxygen to flow out the top.
Over time, the cup seals wear and the compressor does not operate properly.
5.5.1 Compressor Assembly Removal
1. Remove PSA system assembly per Section 5.4.
2. Stand the PSA assembly upright and loosen the center bolt using 5/32” Allen wrench.
(See Figure 5.16.)
Figure 5.16
3. Remove the compressor by pulling the compressor away from the PSA assembly.
Care should be taken not to separate manifold from beds.
(See Figure 5.17.)
