Gas Turbine Inlet Filtration.

Braden manufactures high-performance OEM replacement gas turbine cartridge filters engineered to meet or exceed the performance of filters supplied by leading manufacturers, including Parker, Donaldson, AAF, Freudenberg, and Pneumafil. Built for both pulse-cleaned and static inlet systems across coastal, desert, industrial, and high-humidity applications.

Why Inlet Filtration Matters

Protect output, heat rate, and compressor cleanliness.

Gas turbine intake filtration is critical to maintaining turbine performance. High-efficiency cartridge filters protect against airborne contaminants such as dust, salts, hydrocarbons, and moisture, all of which directly affect turbine efficiency and lifecycle costs.

Stable differential pressure

Maintains low and stable ΔP across the service life of the filter.

High dust holding capacity

Engineered media holds more particulate per filter, extending change-out intervals.

Protects against fouling and corrosion

Stops salts, hydrocarbons, and abrasives from reaching the compressor.

Extends service intervals

Longer filter life means fewer change-outs and lower lifetime cost of ownership.

Cartridge Designs

Four core cartridge designs, matched to your inlet system.

Braden manufactures cylindrical, conical, LM6000, and twist-lock cartridges sized to OEM housings and optimized for the airflow your system was built for.

  • Lower operating ΔP over time
LM6000 canister cartridge filter with a fabric pre-filter wrap visible at one end
LM6000

LM6000 Canister

  • Sized for GE LM6000 inlet systems
  • Pulse-cleaned and high-efficiency media
  • Shipped with pre-filter wraps installed
Twist-lock cartridge filter with the mounting hardware visible at the top end cap
Twist-Lock

Twist-Lock (Pneumafil-style)

  • Direct replacement for twist-lock mounts
  • Faster, more secure change-outs
  • Compatible across GE, Siemens, Mitsubishi
Built For The Environment

One inlet system, four very different environments.

Climate and contaminant profile drive the right media spec. Braden cartridges are configured for the conditions actually on site.

Coastal & humid

Salt-laden, high-humidity sites where moisture and corrosion are constant threats.

100% Synthetic · HEPA
Desert & high-dust

Heavy particulate loading and abrasive contaminants. Pulse-cleaning systems work hardest here.

Premium Nanofiber
General industrial

Mixed particulate, hydrocarbons, and the usual plant ambient. The everyday workload.

Blended · Synthetic
Critical & high-purity

Submicron control and salt/water barriers for the most demanding installations.

E12 HEPA
Filter Media Options

Match the media to the environment.

Braden offers a full media range, from premium nanofiber to HEPA, so the filter spec actually fits the conditions on site.

Premium Nano Fiber

  • Surface-loading for fine particulate
  • Lower pressure drop
  • Extended service life
MERV 11

Blended Media

  • Cost-effective solution
  • Balanced efficiency and durability
MERV 13 & 15

100% Synthetic

  • Moisture resistant
  • Stable in humid environments
  • Excellent dust holding capacity
E12

HEPA & High Efficiency

  • Up to 99.5% on submicron particles
  • Salt and water barrier
  • Suitable for critical environments

Which media is right for your site?

The right media is driven by climate, contaminant profile, and the cleaning regime your system uses. Use this as a starting point:

  • Coastal or humid: 100% synthetic or HEPA (water-resistant).
  • Desert or high-dust: nanofiber, optimized for pulse cleaning.
  • General industrial: blended or 100% synthetic.

We also offer spun-bond media for pre-filtration and specialty applications. If you're unsure, send us your site conditions and we'll spec the right combination.

FAQs

Gas turbine filtration, answered.

What is a gas turbine cartridge filter?

A cartridge filter is the primary filtration element used in turbine inlet systems to remove airborne contaminants before they reach the compressor.

Can Braden replace OEM filters like Donaldson or Pneumafil?

Yes. Braden manufactures direct OEM replacements for every major brand, including Donaldson, Parker Hannifin / Clarcor, AAF, Freudenberg / Viledon, Pneumafil / Nederman, and Camfil Farr, with equal or improved performance.

What filter media should I use for my environment?
  • Coastal or humid: 100% synthetic or HEPA (water-resistant).
  • Desert or high-dust: nanofiber, optimized for pulse cleaning.
  • General industrial: blended or 100% synthetic.
Do replacement filters affect turbine performance?

Yes. Poor-quality filters can increase differential pressure and reduce turbine output. High-performance filters maintain stable airflow and protect efficiency.

How long do cartridge filters last?

Typical service life is 24 to 48 months, depending on environment, media type, maintenance practices, and dust loading.

Are filter wraps needed?

On static (non-pulsed) systems, filter wraps protect the cartridges from larger airborne particles and contaminants and extend service life.
