As part of MEDTEC China 2008, taking place September 9-11, Perma Pure plans to showcase its ME™-Series moisture exchangers.

Designed to achieve moisture balance in medical applications, the ME-Series moisture exchangers for breath sample dryers, filters, and sample lines use proprietary Nafion technology to dry or humidify medical gas and breath sample streams, without altering gas composition and with no utility requirements, according to the company.

The antibacterial membrane tubing does not require power input for operation, and there are no moving parts to fail. In either drying or humidifying applications, the products seek equilibrium with room humidity, transferring water vapor into or out of the tubing in a stable, self-regenerating cycle.
