Fuel Gas Filtration

Throughout the oil & gas and power Generation industries, natural gas has Become the preferred fuel for providing motive power. Effective filtration systems help ensure the demands of modern engines are met by providing clean, dry gas. Failure to provide this can quickly cause a reduction in efficiency or even worse, an unscheduled outage. Indufil fuel gas filtration units are individually tailored to maximize reliability whatever the condition of the supply gas. They are fitted as original equipment by many of the major gas turbine suppliers.

Filtration performance to 3μm and efficiencies to 99.9%(s3-1000)

Inlet and outlet sizes up to 12`` internal diameter

Liquid level indicators, switches and transmitters

Integrated thermal relief and shut off valves

Plug and play filtration unit mounted on its own base frame

Liquid Filtration

Indufil liquid filters are typically used on oil and water duties and can be applied to almost any liquid application.

Lube oil filtration – gas turbines / steam turbines / gearboxes / compressors

Water – gas turbines / injection / machine cooling Duplex filters are recommended to ensure adequate filtration of the process flow while the filter is changed for servicing.
