Test System GTS 114

The test system GTS 114 for testing air intake filter systems for rotary machinery is based on the well-established ALF 114 filter test system for general air filters (ISO 16890) and extended to fulfil the specifications of ISO 29461.

Standards

The GTS 114 was developed with the aim of testing filters with different shapes (filter cartridges, cassette filter, filter with filter bags and plane filter media) using varying test aerosols (salt, oil) under adjustable air conditions (air humidity, temperature) within the test duct. By using the test system the following filter characteristics can be determined: differential pressure curves, dust holding capacity, gravimetric efficiency, fractional efficiency, salt removal efficiency (ISO/AWI 29461-4) and water endurance (ISO 29461-2).

Benefits

• circulation mode for control of the test parameters temperature and humidity
• injection of different aerosols (NaCl, KCl, DEHS) into an optimal flow profile
• automated feeding of water droplets and supersaturated vapour
• high level of automation, mostly automated test runs with complete operator guiding

Applications

• testing of gas turbine intake filter systems according to ISO 29461-2 and ISO/AWI 29461-4
• testing of general air filters (ISO 16890, EN 779, ASHRAE 52.2)

Accessories

• aerosol substance DEHS
