FAIST - Air Intake Systems and Noise Control Systems for Power Plants

FAIST is a well-established company specialising in air intake systems and noise control solutions for a wide range of applications worldwide. Our noise control products and services cover acoustic enclosures, air intake systems, control rooms, rectangular and circular silencers, acoustic screens, acoustic louvers, acoustic doors and integrated systems.

A privately owned company since 1904, FAIST has become an experienced supplier of air intake systems and noise control systems for power plants as well as for many other key industries, such as the automotive, mechanical engineering and print industry.

Air intake systems

FAIST has developed a standard module design for air intake systems which enables the efficient construction of filter arrangements, regardless of turbine manufacturer or size.

This design flexibility is possible for multistage (static) filters with compact pre-filter, fine- and HEPA filter or self-cleaning pulse filter systems. Whether the installations are offshore, onshore, coastal area, tropical area, desert area, etc., maximum standardised project solutions are obtained.

• Cost optimisation through standardisation
• Special baffle design to significantly reduce pressure drop with improved noise reduction
• Higher gas turbine output and higher unit profits by lower pressure drop
• Cooled intake air for perfect turbine performance at higher temperatures

Optimisation of the air intake silencer

Due to a patented concept of the FAIST silencer design, a significant reduction of the air intake silencer-pressure loss can be achieved. The use of such a silencer design will increase the gas turbine performance and power output. In addition, this design concept reduces the investment costs of air intake ducts and silencer sections.

Additional applications for air intake systems

FAIST air intake systems can be equipped and delivered with all kinds of additional applications. Examples of such applications are:

• Anti-icing systems with hot air from the GT-compressor
• Anti-icing systems with heat exchangers (water / glycol)
• Wet compression systems to improve performance of gas turbines
• Evaporative cooler systems to improve performance of gas turbines

Worldwide network for customised noise control / air intake systems

FAIST has an international distributor network to ensure the worldwide availability of noise control systems and air intake systems. This network also enables global sourcing for competitive prices.

FAIST's globally active customers include Alstom, Siemens, MAN and Kawasaki.

Noise control and ventilation for turbines

FAIST provides state-of-the-art solutions in noise control and ventilation for turbines (gas and/or diesel) based on many years of experience. We look at every aspect of the noise solution, providing customer solutions from survey to design, manufacture, installation and finally commissioning.

We have created very effective systems to meet the high standards of our customers. Enclosure ventilation is a very important aspect in the treatment of power plant enclosures. Ventilation air must be carefully determined and treated to meet equipment requirements in normal as well as extreme ambient air conditions.

The advantages of our noise control and ventilation system:

• Each acoustic panel can be easily removed
• Easy turbine maintenance
• Rapid exchange of large components
• Professional selection and design of the ventilation system
• Permanent development of our products due to long-term agreements with our customers

Sound insulation for compact packages

Compact packages are the best solutions for power plants in the lower power output range. FAIST sound insulation provides vital advantages:

• Hardware installed on site within three working days
• All components are pre-assembled at our plant
• Mechanical acceptance check of sound hood and filter housing in our shop
• Rapid and easy start-up thanks to pre-fitted gas turbine enclosure and air intake connections
• Significant cost saving for the completed package
• Use of explosion-proof components for the compact packages upon request
• Clean room conditions in the area between the filter housing and sound hood minimising turbine inhalation of unwanted dirt and debris, which greatly reduces the possibility of turbine damage

In-house powder coating for environmental protection

• Our paint system is in compliance with corrosivity category C5-I/M - high according to ISO 12 944-2 Table 1, achieving a durability period of more than 15 years
• The company owned powder coating plant works without producing any waste
• ISO 9001:2000 and ISO 14001 certified
• Corporate responsibility for a sustainable business development
