Air Filter Inlet Systems for Gas Turbines Pulstar Series ® APPLICATIONS Pulstar is a pulse-jet, self cleaning inlet air filtration system for gas turbines and axial compressors operating in severe environmental conditions. The Pulstar series air filtration system is the result of many years of design, testing, and field experience. The Pulstar utilizes state-ofthe- art technology to provide the most efficient and effective continuous duty filtration system available. FEATURES ¡ Low Intake Velocities The unique design of the weatherhood provides protection and lowers intake air approach velocities. The low velocity means less contaminate reaches the filter elements and agglomerated dust cake is not readily reentrained after pulse cleaning. Media face velocity has been optimized and reduced. ¡ Low Initial Differential Pressure The Pulstar systems have the lowest initial pressure drop in the industry, due to the elimination of restrictive venturis and increased outlet diameter of the filter cartridge. Pulstar filter cartridge performance data is based on testing in accordance with ARAMCO 32-AMSS-008. ¡ Cartridge Geometry Pulstar incorporates the use of nominal 36" filter cartridges. This allows more media per cartridge and a larger diameter air outlet into the clean air plenum, which reduces operating pressure drop. Moisture resistant media is standard on all Pulstar systems. A variety of special synthetic media is available for more difficult operating environments. ¡ Heavy Duty Construction Pulstar housings, walls, and tube sheets are fabricated to increase structural strength. ¡ Easy, Fail-Safe Filter Installation Easy to install and service, all filter cartridges are installed from the underside of the housing. An extended shaft, threaded handle secures the filter in place. The molded neoprene gasket provides a fail-safe seal at the tube sheet. No special tools are needed. ¡ Upflow, Crossflow, and Downflow Models Available Pulstar filters are available in upflow, crossflow, and downflow designs to accommodate physical layout and cost parameters. All designs have a full range of weather protection options to accommodate specific site conditions. ¡ Self-Cleaning or Barrier (Static) Filters Available The self-cleaning Pulstar uses pulse air delivered through 1-1/2" diameter blow pipes with accelerator nozzles. No venturis are required. The shock effect from the pulse air removes the dust cake agglomerated on the outside of the filter. Pulstars can also be used as barrier (static) filters. The filters are replaced when final resistance is reached. ¡ Standard and Custom Designs Available Modular construction means custom and standard designs are available for large and small applications. Pulstars have been installed with as few as four filter elements. Larger installations use several hundred filter elements and stand more than 70 feet tall. You may purchase the Pulstar system only or make use of our extensive industry experience, worldwide manufacturing capabilities, and in-house engineering expertise to develop packaged systems to meet your exact intake specifications. Pulstar filter cartridges are designed to minimize pressure drop.
