Standard Features of the Eta 2000 Collectors

FABRIC FILTERING SYSTEM

The tube sheet is full 3/16" thick, HRS plate welded to the collector housing, with a 6" lazer cut hole to provide a positive, trouble-free seal. 

The Eta 2000 six inch diameter fabric filter bag attachment features "snap-ring" installation, which requires no tools. This fast one-man process allows bags and cages to be installed from the CLEAN SIDE of the collector. This simple installation procedure creates the only seal necessary, eliminating the need for any additional seals or gaskets. The Eta 2000 offers a complete range of high-quality fabrics in all popular synthetic fibers, including high temperature fabrics.

The Eta 2000 venturi and cage assembly, designed to conserve compressed air, is of heavy-duty, welded construction and permits installation without tools. The high-gain venturi throat of the Eta 2000 is fabricated from spun steel and is capable of cleaning more surface area of filter media with less compressed air. This provides effective cleaning of the 6 inch diameter bags for lengths up to 14 feet long with the collector on line.

The Eta 2000 cage is constructed from heavy-gauge, carbon steel wire to provide maximum support. It can be installed without tools. The assembly is self-aligning when placed into the bag, and is supplied with a metal ring that protects the top edge of the filter bag when the cage is installed. Galvanized, stainless steel, or corrosion-resistant coating are available for special applications.

The Eta 2000 pulse control board is a printed circuit timer board designed to control the pulse cleaning sequence. It has proven to be both trouble-free and reliable. The board and a photohelic differential pressure switch are mounted in a NEMA 4 panel located on the pulse service platform.

The Eta 2000 standard pulse valve is a double-diaphragm valve fitted to the square compressed air manifolds. This pulse valve is designed to work with the pulse pipe and cage venturi to provide maximum cleaning efficiency for up to 17 bags per row. The basic design of the ETA 2000 standard pulse valve eliminates the need for remotely operated pilot valves and maintenance problems that are associated with them.

The standard Eta 2000 1-1/2 inch diameter pulse pipe has jig-drilled blow holes for a positive alignment over the center of the cage venturi to provide maximum efficiency, eliminating the possibility of misalignment. For bag inspection and/or removal, the pulse pipes can be removed with minimal effort and with no special tools.

The Eta 2000 pulse manifold is made up of heavy wall square tubing. Each manifold serves no more than 10 pulse valves, thus permitting isolation for maintenance without shutting down the total system. The segmented manifold design provides for rapid "replenishment" of air pressure following a cleaning pulse. The system is designed to operate at 90 PSI, however each manifold is shop-tested to 150 PSI.
