Turbomachinery filters

Turbomachinery filters

​​​Air inlet filtration systems are essential for the operation of gas turbines and other turbomachinery. We breathe about 27 kg (60 lbs) of air each day while a 15 MW engine will ingest about 4,300 tons of air in the same day.

If particles enter the machinery, they can cause erosion, fouling or corrosion of the turbine internals. To avoid unnecessary damage to the machinery, we provide gas turbine filters which meet the most stringent demands for burst strength, particle filtration efficiency and life time from the OEM turbine manufacturers.
There are two main types of filtration systems, static and pulse, also known as self cleaning systems. Filtration takes place in one or several stages with increasing filtration efficiencies from G4 up to H13.

Bag or pocket filters are mainly used as pre/first stage filters in the gas turbine air inlet to remove coarse impurities and act as coalescers to remove smaller water droplets from the air stream.

Compact or mini-pleat are high efficiency air inlet filters used for second and/or third stage filtration, depending on the gas turbine air inlet system.

Our box type compact filters feature a robust design, high efficiency and low pressure drop, making them a reliable and economically sound choice for turbomachinery in tough, humid conditions.

Our cartridge filters, both self-cleaning pulse and static, are available in vertical or horizontal designs to best suit your system of choice.

Our panel filters are usually used as prefilters or first-stage filters in static inlet systems for gas turbines. Their main role is to remove larger particles such as pollens and other coarse impurities as well as water droplets.
