BBM Acoustic develops, designs, supplies and assembles filter systems for turbomachinery including Gas Turbine compressors, Centrifugal compressors,Ventilation requirements, Noise control Enclosures, Diesel Generators, Blowers etc. 

BBM Acoustic offers solutions for filter systems suitable for all environmental conditions and other specifications such as acoustical requirements. Generally, we distinguish between conventional static filter systems and self-cleanable pulse filter systems.

BBM Acoustic has been engineering the most significant parts of filter systems to ensure the highest performance and best quality.

Airintake systems – Our features are listed below:

  • Compressor bleed air or exhaust
  • Heat exchangers
  • Infrared systems
Static air intake systems

Our static air intake system comprises bag filters and fine filters as well as weather protection hoods, droplet separators, bird screens, anti-icing-systems, inertial separators, control systems for monitoring the pressure drop of the filter systems, bypass flaps, shut-off louvers, roller shutters and other ancillaries.

Mist eliminators

We use filter elements in classes G9 to F9 in accordance with EN 779. Special gas turbine types are also equipped with EPA or HEPA filter elements up to E10 – E13 or H13 according to EN 1822. Especially concerning efficiency, maximum power load and endurance we recommend the use of our specially developed gas turbine BBM Acoustic filter cells (M5 – M6, F7 – F9, E10 – E13, H13).

Self-cleaning pulse filter systems

Our typical self-cleaning pulse filter system consists of weather hoods, droplet separation and single stage pulse filter elements. On demand it is also equipped with e. g. high efficiency safety barriers filters. The necessary compressed air cleaning components include manifolds, valves, blowpipes and pulse controls.


Obsolete filter technology, degeneration or installation of bigger gas turbines cause increased demands on turbine efficiency. BBM Acoustic offers a broad range of retrofit and upgrade solutions.

ARAMCO test stand

Our special test rig enables the investigation and development of air inlet filters, especially the testing of semi-automatic Gas Turbine inlet filters according to the ARAMCO standard (32-SAMSS-008). Due to various and flexible features of our test rig, it is possible to determine the filtration characteristics of all kinds of air-filtration elements in any environmental conditions.


UpStream Cooling System – [ UpS ] This system is perfect for retrofit installations. Often there is not enough room in the existing air intake to install an adequate and efficient cooling system. Filter house modifications are expensive and result in a long downtime for the GT. Or modifications are in all prohibited due to warranty contracts. No water treatment on site is needed. 

The Up-Stream Cooling system is installed outside the air intake in front of the weather hoods. The system can be installed and maintained from the outside without disturbing the GT operation.

No risks of water or other foreign objects inside the air intake that may damage the compressor. No demineralized water needed. The UpS system mesh will additionally filter the air from large particles for an air washing effect and longer air filter lifetime. Easy installation and maintenance.


Adiabatic cooling: > 93% efficiency

Wide range of water quality can be used

Additional air washing effect

No water inside air intake

Easy retrofit solutions

No GT Shutdown required for installation

Technical details

Power gain: 0.6 – 1% per 1°C of cooling

Differential pressure loss < 50PA

Optimized design for minimum pressure loss

Low power consumption

Guaranteed dry air intake

Installed upstream of filter hous

Evaporative Cooling System – [ EVAP ]

This system is commonly installed after the first air filter stage. Water is distributed over a special media/pad with a very large surface. The air is lead through the pads where it cools down adiabatically.

Demineralized water is recommended but is not mandatory depending on the pad material and site conditions.


Adiabatic cooling: > 90% efficiency

Wide range of water quality can be used

Simple cooling technology

Technical details

Power gain: 0.6 – 1% per 1°C of cooling

Differential pressure loss < 75PA

Negligible power consumption

Installed down- or upstream of air filters

High Fogging System – [ HFOG ]

This system sprays the water directly before the compressor. Therefor the majority of the fine water spray will enter the compressor and evaporate there. This is also called Compressor Inlet Cooling or Wet Compression.

The advantage of this system is to give the GT an additional power boost whenever needed and without being dependent on ambient conditions. Even in tropical regions with high humidity, you can get an important power increase whenever needed.


Wet compression up to 2% water flow

All droplets evaporate inside the compressor

Not dependent on ambient weather conditions

NOx reduction

AxE Nozzles match GT outage intervals

Technical details

Power gain: 5% per 1% of water flow

Differential pressure loss < 100PA

Negligible power consumption

Installed upstream of GT compressor
