Gas Humidification Selection Guide

Many applications require a gas stream to be humidified, such as calibration gases, aerosol streams, or incoming air for fuel cell systems. Using Nafion™ polymer, Perma Pure has developed an array of products that humidify gas streams in two modes – either gas to gas or water to gas.

MH™ Series Humidifiers

  • Water to Gas Humidification
  • Flow Rates 0- 10 lpm
  • Single Tube Humidifier

Perma Pure MH™-Series humidifiers use exclusive Nafion™ tubing selectively permeable membrane tubing and liquid water to continuously humidify gas streams. These humidifiers operate over a wide range of flow rates, and humidify up to 98%RH using de-ionized water as the humidification source.

FC Series™ Humidifiers

  • Gas to Gas or Water to Gas Humidification
  • Flow Rates 10-1000 lpm
  • Multitube Humidifier

Perma Pure’s FC Series™ Humidifiers are a series of high capacity humidifiers that are used for a wide variety of applications, including the exacting requirements of the fuel cell user, setting the industry standard with unparalleled performance, reliability and lifetime.  These Nafion™ tubing -based products provide consistent, repeatable humidification of air and hydrogen across the specified flow range.  Perma Pure humidifiers feature a low pressure drop and do not require power to operate (in gas to gas mode), greatly reducing the parasitic load on your system.   The FC Series™ – your best humidifier choice for portable, stationary, materials handling and automotive applications.

BE Series Humidifiers

  • Gas to Gas Humidification
  • Flow Rates to 2 lpm
  • Single Tube Humidifier

The BE Series transfers moisture from one gas stream to the atmosphere using a single Nafion™ tubing. These are typically chosen when the sample gas only needs to have its humidity equalized to the atmospheric RH. The most common application is to humidify calibration gases. A wide range of lengths and tube diameters is available to cover these applications:

0-0.2 lpm: ME-050 Series
0.1-1 lpm: ME-070 Series
1-2 lpm: ME-110 Series
