12.1.2 Insect Screens
Optional insect screens can be installed on each side of the air inlet filters (except for
self-cleaning filters). This option is used with the air filter when large numbers of insects
are present. The insect screen design reduces the velocity of the air stream sufficiently to
allow most insects to fly away. Use of the screen helps to avoid clogging and premature
filter replacement. During cold weather operation, the insect screens should be removed
and stored due to a potential for ice or snow to clog the screens.
12.1.3 Self-Cleaning Barrier Type Air Filter (Updraft Type)
The self-cleaning barrier type air filter system is suitable for extreme environments where
dust loading or cold-weather operation is a concern. This system requires a suitable
supply of cleaning air. Cleaning air can be provided by the customer or supplied using
turbine compressor discharge pressure (Pcd) bleed air. If bleed air is used, an air heat
exchanger is provided for mounting in the air inlet ducting between the air inlet filter and
the turbine air inlet. Access to change filter elements from below must be provided
Standard features include:
• Support leg kit
• Dual differential pressure alarm and shutdown switch
• Filter elements
• Differential pressure gauge
• Electrical connections prewired to a common junction box
12.1.4 Marine-Type
The marine-type air filter system is suitable for use in coastal, offshore, and tropical
locations. This system provides high efficiency removal of salt, water, and particulates.
This system consists of:
• First stage marine vane separator/moisture eliminator
• Second stage prefilter
• Third stage high efficiency bag filters
• Fourth stage marine vane separator/moisture eliminator
Access doors are provided in the first stage marine vane separator/moisture eliminator
for filter removal. Standard features include:
• High performance drainage system
• Transition outlet flange
• Lifting lugs
• Instrumentation panel
• Differential pressure gauge
• Electrical connections prewired to a common junction box
• High differential pressure alarm and shutdown switches
12.1.5 Air Inlet Silencer
Optional air inlet silencers can be incorporated into the air inlet ducting to reduce noise
levels. Typical installations include one air inlet silencer..
12.1.6 Air Inlet Ducting and Support
An optional support structure and ducting can be provided for offskid support of the air
inlet filter and silencer assembly. Attaching hardware and a tube of sealant are provided
for one flange per duct.
