Rosedale Beta Bag® Filters
Filter bags for fine filtration requirements

After years of supplying filter bag products to the process industries, Rosedale has developed a new filter bag that meets even more exacting requirements, extending their use to finer process filtration and to hydraulic and lubricating fluid filtration. Rosedale Beta Bag® filter bags are made of a unique multilayer polyester felt, encased in spun-bonded nylon to prevent possible migration of bag material into the fluid stream. They’re rated by the multi-pass method of filter performance evaluation, so that direct comparison can be made between Beta Bag® filters and cartridges of rigid construction using cellulose or synthetic elements, pleated or non-pleated. They compare very well:

• Because disposable Rosedale Beta Bags® are fitted into and supported by perforated-metal baskets, you need not be concerned with filter collapse, flow fatigue, or filter end-load problems.
• Beta Bags® can be installed and removed from their housings in a fraction of the time required to service rigid cellulose or synthetic element cartridge filters.
• Beta Bags® cost less than cylindrical filter cartridges, and they fold flat for more compact storage.
