Experts in air filtration and auxiliary equipment
AAF has been providing high quality gas turbine filtration systems, auxiliary equipment, acoustic and damper solutions, and replacement air filters to OEMs and Operators for over 50 years. During that time, we’ve executed thousands of projects around the world, including in some of the most challenging industries and demanding environments.
We strive to ensure your assets utilise the best available technology to maximise efficiency, availability, and reliability. We offer the same level of support for large industrial air compressors, which are used across various applications including air separation.

Air Intake Filtration System

Weather Hoods
A gas turbine weather hood is the best possible protection against the ingress of rain, snow, sleet and hail. AAF weather hoods are designed so the air enters the inlet system vertically upwards and in doing so makes it extremely difficult for large amounts of moisture to enter the inlet filtration system.
- Wide range of designs
- Available in different material options

Air Inlet Heating Solutions
Close
Air Intake Filtration System
A gas turbine or large compressor air intake filtration system forms a vital part of any given plant. The volume of intake air, the surrounding environment, and the operating conditions all play a major role in the design and filter element selection process. See related products for further details.
- Extensive product range
- Solutions to suit all applications

Air Inlet Cooling Solutions
Close
Air Inlet Heating Solutions
Inlet heating systems for cold climates are designed to protect gas turbines from damage due to icing and to keep the machine running with minimum effect on performance. Icing can block inlet filtration equipment, increasing pressure drop, and potentially cause the gas turbine to shut down
- Heat the inlet when the engine is offline
- Prevent frost and ice damage
Close
Inlet Silencer & Exhaust Silencer
Close
Air Inlet Cooling Solutions
Gas turbine output is affected by the temperature of the air entering the compressor. Gas turbines are rated at a temperature of 15 °C (59 °F). If the temperature increases above this point there is a loss of power, but this can be restored with AAF’s cooling solutions.
- Boost power output
- Short payback period

Optimize your Gas Turbine
Close
Inlet Silencer & Exhaust Silencer
A gas turbine silencer is found in the intake as well as the exhaust to meet the overall noise control requirements. Once the acceptable sound level has been established it is then a matter of determining the amount of attenuation needed to reduce the noise to the desired level.
- Wide range of inlet and exhaust silencers and baffles
- Upgrades and modifications available

Optimize your Gas Turbine
AAF Optimize is an industry-leading support service that provides gas turbine users with the capability to improve plant efficiency, availability, and reliability. Optimize assesses your site’s operational, commercial, and environmental data to firstly understand the current impacts and losses associated with your air inlet filtration system.
- Incorrectly specified or poorly maintained air filtration systems can lead to sub-optimal engine performance
- Optimize uses a good, better, best selection methodology and the key benefits are highlighted for further discussion
Close
Dampers
Close
Ventilation System
A gas turbine ventilation system feeds into the gas turbine enclosure and is designed to remove the hot air generated when the turbine is operating with ambient air from outside. Incoming air can be cooled or heated depending on the seasonal conditions and filtered to remove air contamination.
- Avoid gas pockets inside the enclosure
- Cool sensitive components
Close
Wide Range of Filters
Close
Dampers
In a gas turbine application, a damper is used to allow the hot exhaust gas to either be discharged through a bypass stack or redirected into a Heat Recovery Steam Generator (HRSG). Steam is generated for industrial processes or to drive a steam turbine to generate more electricity.
- Available in a wide range of designs and sizes
- Low thermal losses and optimal sealing technology
