Invacare Perfecto 2 V Oxygen Concentrator The finished device is packaged as a single unit. The service part contains a single pair of sieve beds; one pair of sieve beds is used in a single finished device. Intended to provide supplemental oxygen to patients with respiratory disorders, by separating nitrogen from room air, by way of a molecular sieve.

Reason: It was determined that a defective sieve bed subassembly enabled zeolite sieve dust from the sieve beds to migrate into the valves of the manifold assembly and muffler causing a reduction in oxygen concentration.

Code information: The defective sieve bed subassembly manufactured from 7/31/2014 to 8/19/2014 impacts the finished device- IRC5PO2V and Service Part Number-1165099. The serial number range is as follows for the finished device: 14GF053772-14HF032124 (Sequential serial numbers)
