Welker CleanFlow Instrument Grade Gas Conditioning System

CleanFlow™

Clean, dry, regulated pipeline gas for dependable pneumatic instrument performance.

The Welker CleanFlow™ Instrument Grade Natural Gas System removes liquids, moisture, and contaminants from pipeline gas so it can be used as a clean, dry supply source for pneumatic instruments and pneumatically actuated equipment. Designed for natural gas compressor stations, refineries, offshore production sites, processing plants, emergency shutdown valves, control valves, and automated ball valve assemblies, CleanFlow™ combines Welker filter drying, integrated pressure regulation, optional liquid dump protection, and optional catalytic heating to help prevent clogs, freezes, equipment damage, and service interruptions.

Where to Use

Natural Gas or Instrument Air Supply Lines

Upstream of pneumatic instruments, pneumatically actuated equipment, emergency shutdown valves, control valves, and automated ball valve assemblies.

Cold or Moisture-Prone Locations

Helps condition pipeline gas in locations with low ambient temperatures or supply gas moisture.

Industrial Gas Facilities

Natural gas compressor stations, centrifugal compressors, reciprocating compressors, oil refineries, offshore production sites, and processing plants.


Industry-Recognized Welker Filter Dryer

Removes liquids, moisture, and contaminants from pipeline gas to help protect pneumatic instruments from damage, clogs, and freezing.

Integrated Regulator System

Reduces pipeline pressure to a functional instrument supply range for safer, more reliable downstream operation.

Industry-Recognized Welker Filter Dryers

Remove moisture, liquid hydrocarbons, and mercaptan to help protect downstream pneumatic instruments.

Optional Welker ALD or MLD Liquid Dump

Adds automatic or manual liquid removal to help prevent liquid carryover into sensitive pneumatic equipment.

Optional Catalytic Heater

Heats pipeline gas to the desired temperature to help reduce freezing risk and maintain instrument supply performance.
