Perma Pure’s FC Series™ humidifiers are the industry standard and offer unparalleled performance, reliability and lifetime.

Perma Pure ME™ – Series moisture exchangers selectively remove only water vapor from the sample, virtually eliminating this source of analyzer failure. Available in a variety of tube diameters, lengths, and fitting combinations, the ME™- Series can be used in a variety of applications and across a wide range of flow rates.

Perma Pure MD™-Series gas dryers use exclusive Nafion selectively permeable membrane tubing to continuously dry gas streams removing only water vapor. These dryers operate over a wide range of temperatures, pressures and flow rates, and dry to dew points as low as -45°C.

Perma Pure PD-Series™ gas dryers are multi-tube Nafion dryers designed for high flow, high performance gas drying applications. These dryers can be used to dry to -45°C without removing other compounds.
