Gas turbine inlet filters: pulse vs static

Inlet filters decide how much dust and salt reach the compressor. The first choice is how the cartridges get cleaned, or whether they do.

Why inlet filtration matters

A gas turbine pulls in a very large volume of air. Dust and salt that get past the inlet filters foul compressor blades and cut output, so the inlet filter house is the first line of protection for the engine.

Pulse cartridges

Pulse cartridges are cleaned in place by reverse pulses of compressed air. The pulse knocks the collected dust off the media, so they suit dusty sites where filters would otherwise load quickly.

Braden manufactures pulse cartridges in cellulose MERV 15 and MERV 16 and synthetic MERV 15, as cylinder and conical sets.

Static cartridges

Static cartridges are not pulse-cleaned. They are replaced when loaded, and they can be built to higher efficiencies.

Braden manufactures static cartridges in synthetic MERV 15 and MERV 16 and HEPA E12 and H13, as cylinder and conical sets, plus cylinders-only for the LM6000.

Cross-referencing your current cartridges

Most inlet houses run a specific cartridge size and flange. Send Braden the OEM part number or a photo of the label and a specialist matches it to a drop-in replacement Braden manufactures, with no change to the filter house.

Common questions

Does Braden make LM6000 inlet filters?

Yes. Braden manufactures cylinders-only static cartridges for the LM6000.

What is the difference between pulse and static gas turbine cartridges?

Pulse cartridges are cleaned in place by reverse pulses of compressed air, so they suit dusty sites. Static cartridges are not pulse-cleaned and are replaced when loaded. Braden manufactures both.

What efficiencies do Braden gas turbine cartridges come in?

Pulse: cellulose MERV 15 and 16, synthetic MERV 15. Static: synthetic MERV 15 and 16, HEPA E12 and H13.
