Fuel Grade Purity Hydrogen Gas Generators

Supplier: Absolute Filters

Hydrogen On Demand, up to 500 cc/minute - ChromGas fuel grade purity hydrogen generators from A-F are designed as hazard-free alternatives to high pressure gas cylinders.


They can be used with any instrumentation requiring fuel grade purity hydrogen - anywhere a standard electrical supply is available.

Deionised water is all that is required to generate hydrogen for weeks of continuous operation.With an output capacity of up to 500 cc/minute, one generator can now supply 99.9995% pure fuel gas to over (10) GC's. Based on cylinder gas savings alone, a ChromGas hydrogen generator pays for itself in less than a year.

Certified Safety

AF's ChromGas hydrogen generators use Proton Exchange Membrane to produce fuel grade hydrogen on demand. Only 100 mL is stored in the system at any time and at low pressure. A built-in sensing circuit shuts the generator down if a hydrogen leak is detected.

That's why AF's ChromGas hydrogen generators meet the strict, safety guidelines of the National Fire Protection Agency (NFPA) and the regulations of the Occupational Safety and Health Association (OSHA - 1910.103). Most importantly, they are the only hydrogen generators certified for laboratory use by CSA, UL and IEC 1010.

99.9995% Pure

The exclusive proton exchange membrane has been complemented with a scrubber to generate 99.9995% pure hydrogen. That's why AF's ChromGas hydrogen generators are recommended by GC manufacturers.

AF's ChromGas proprietary replaceable purification cartridge provides fuel grade purity (99.9995%) for fuel gas usage and ensures consistent reproducible results.

Proven Technology

AF's ChromGas Proton Exchange Electrolyser eliminates the use of liquid electrolytes with hydrogen generators.

Proven in over 40,000 GC installations worldwide, AF's ChromGas generators are the most reliable hydrogen generators on the market. Maintenance requires only a few moments per year - no inconvenient, extended downtime.

Simply change the deioniser bag every six months and the purification cartridge whenever it turns beige. And if contaminated water or low water level is detected, the system activates a warning light and shuts off the generator - avoiding damage to the electrolytic cell.

Proton Exchange Membrane Electrolysers are also extensively used in Navy submarines and NASA supplemental fuel systems. This reliable, high quality hydrogen generation technology is also being considered to fuel the Ultra Low Emission and Zero Emission Vehicles (ULEV/ZEV) of the future.
