Gas turbine inlet air filtration removes dust, moisture and other airborne contaminants before they enter the compressor. Effective filtration helps prevent compressor fouling and erosion, improving turbine efficiency, output and long-term reliability.

August 24–27, 2026 | San Antonio Marriott Rivercenter, San Antonio, Texas | Booth T-55
Power generation reliability is under more scrutiny than ever. Aging combined cycle fleets are cycling more often and running longer between outages, all while plants are expected to keep availability high. In that environment, the equipment that quietly protects a gas turbine's health, starting with the air it breathes, deserves more attention than it usually gets.
That's the conversation Nederman Pneumafil looks forward to having at the Combined Cycle Power Users Annual Combined Conference 2026, August 24-27, 2026, at the San Antonio Marriott Rivercenter on the Riverwalk. The event brings together the Combined Cycle, Generator, Power Plant Controls, Steam Turbine, and Low Carbon Peer user groups, the exact operators, reliability engineers, and asset managers who make gas turbine inlet air filtration decisions every day. If you manage or maintain gas turbine assets, this is a good moment to plan a stop at the Nederman Pneumafil booth, Booth T-55, during the Vendor Fair.
A gas turbine is only as efficient and reliable as the air moving through its compressor section. Every cubic foot of intake air passes through the turbine inlet filters first, which puts filtration in direct line with most of the performance metrics plant staff track. Poor or degraded filtration shows up in predictable ways:
Because the inlet system sits upstream of everything else, a well-designed and properly maintained gas turbine air filter program is one of the more cost-effective ways to protect the rest of the asset.
Talk to almost any reliability engineer or maintenance manager at a combined cycle or peaking facility and a few themes come up again and again:
Nederman Pneumafil approaches inlet air filtration as an engineering problem first, not a commodity purchase. Our team evaluates the full inlet system, not just the filter element, so recommendations account for turbine model, site environment, duty cycle, and the plant's own reliability and efficiency goals. That evaluation typically covers four areas:
Taken together, this approach translates into practical outcomes: fewer unplanned filter-related trips, more predictable pressure drop over a filter's service life, longer intervals between changeouts where conditions allow, and clearer data to support outage planning. Our gas turbine filtration solutions are built around decades of application experience across combined cycle, peaking, and cogeneration facilities operating in a wide range of climates.
One of the most common questions we hear at conferences like this one is simple: can you supply a filter that fits our existing housing without a redesign? In most cases, the answer is yes.
Nederman Pneumafil manufactures OEM-compatible replacement filters matched to inlet systems originally supplied by Donaldson, Camfil, American Air Filter, Braden, and others, across static panel, pulse-cleaned cartridge, and two-stage systems like those on GE LM6000 units. That flexibility lets plants upgrade filtration performance without the cost and downtime of replacing the entire filter house.
Turbine inlet air filter service is only as good as the people carrying it out. Nederman Pneumafil supports plants with a network of certified field service technicians experienced in inlet system inspection, filter installation, troubleshooting, and ongoing maintenance, including:
For plants managing lean maintenance teams, having access to technicians who already understand gas turbine inlet systems, rather than starting from scratch on every service call, shortens response time and reduces the risk of an improper installation affecting turbine performance later.
Not every inlet air filtration problem needs a brand-new filter house. Nederman Pneumafil offers a range of turbine filter retrofits and modernization options designed to extend asset life and improve performance without the cost and downtime of a full system replacement, including:
These gas turbine filter upgrades are typically evaluated case by case, based on the plant's climate, turbine model, and performance goals, so the scope of work matches the actual problem rather than defaulting to a one-size solution.
The Combined Cycle Power Users Annual Conference draws exactly the audience that inlet air filtration decisions run through: combined cycle plant operators, reliability engineers, maintenance managers, and asset managers who are already thinking about turbine availability, efficiency, and lifecycle cost. That overlap is what makes this event worth a stop at our booth, T-55.
Visiting the Nederman Pneumafil team at the Vendor Fair is a chance to:
Whether your plant is evaluating a filter change for the first time in years or actively planning a retrofit, a short conversation at the conference can help clarify what options actually fit your situation.
Stop by Nederman Pneumafil at Booth T-55, Power Users Annual Combined Conference, August 24-27, 2026, San Antonio. Can't make it? Reach out to our team directly.
Yes. Nederman Pneumafil manufactures OEM-compatible replacement filters designed to match the form, fit and function of inlet systems from Donaldson, Camfil, American Air Filter, Braden, Clarcor, Universal Silencer and many other OEMs.
It depends on the condition of your inlet system, operating environment and turbine duty cycle. A field inspection can assess filter condition, pressure drop trends and system integrity to determine whether a filter upgrade, targeted retrofit or full filter house replacement is the best solution.
Cold, humid conditions can cause ice to form on filter elements and inlet components, restricting airflow and affecting turbine performance. Anti-icing modules are designed to prevent ice formation and maintain reliable operation in cold climates.
Yes. Our certified field service technicians perform inlet system inspections, filter installation, troubleshooting and maintenance to help maximize filtration performance and system reliability.
A modern filter house can reduce operating differential pressure, improve airflow, enhance turbine performance and resolve reliability issues associated with aging inlet systems.
