We ordered the co2 absorber to perform preventive maintenance (pm) on the co2 module.The pm procedure states, "the co2 absorber is recommended to be replaced once in four years." we received 5 co2 absorber about a month ago and 4 of the 5 have an expiration date on them of 4 years from now, but the 5 has an expiration date of about 5 years from now.If the absorber is not to be replaced for 4 years then the parts that are being shipped should have a minimum expiration of 4 years as well.If we go by the recommendation we will have an expired absorber in our co2 module.
