BC Filters and Uni-Filters
Product Announcement from FLSmidth
Compressor Intake Filters (BC Filters)
A complete ready-to-install compressor intake air filter which combines generous cloth area and high efficiency. Suitable for pre-filtering air for other applications. Huge dust holding capacity by Air Filter Institute standards. Less bothersome and easier to maintain than conventional oil-wetted or paper element add-on filters.
This unit is a single compartment multi-bag collector for inlet capacities up to 12,000 CFM (340 cmm) at ambient temperatures. Compressor filter sizes have a maximum air-to-cloth ratio of 10.0 to 1.
Three-in-one multibags are made of heavy woven spun polyester for long life.
Model BC-.25 thru BC-1 are operated by manual shakers. Models BC-2 thru BC-7 have shaker motor drives with heavy duty shaking mechanisms. 230/460 volt AC, 60Hz., 3 phase.
Housing and Supports
Model BC-.25 and BC-.50 are fabricated of fourteen (14) gauge carbon steel. Models BC-1 thru BC-7 are made of twelve (12) gauge carbon steel. Models BC-5 thru BC-7include formed steel supports providing a four foot clearance between discharge opening and floor.
On Models BC-.25 thru BC-4 dust discharges into an enclosed box. Larger Models BC-5 thru BC-7 use a pyramid hopper with a 7" (175 mm) square cast iron slide gate.
A gauge is provided to indicate pressure differential across the filter. When the differential reaches 8" W.G. the compressor should be stopped or switched to air by-pass operation so that the unit can be cleaned.
Although not essential, an initial charge of filter aid for cement application will result in top quality air. Reseeding is not necessary for cement application after shaking.
Efficient air filtration will be achieved for several months before cleaning is necessary when the FLSmidth BC Filter is properly installed and seeding carried out according to the instructions.
Unit is shipped pre-assembled. Simple, easy-to-install instructions are provided with each package. Customer supplies for intake and clean air piping to the compressor.
Several compressors may be connected to a single high volume filter. With its unique design, FLSmidth's Compressor Intake Filter provides maximum exposure to the incoming airstream. The result is a high degree of airborne particulate capturing capacity, with an absolute minimum of maintenance. Dust particles smaller than 1/4 micron are trapped and held to provide super-clean air.
FLSmidth Uni-Filters provide de-centralized dust collection from widely separated sources, reducing piping and power costs involved in large centralized systems. Our Uni-Filters have the same engineering construction and operating features which have made our larger fabric collectors a basic tool for industrial dust control. Shipped completely assembled and ready-to-install, Uni-Filters can be located close to dust sources and require only a small operating area. If the dust-creating operation moves or changes, the unit's compact design permits easy relocation.
