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 multipass 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.
• Polyester/nylon bag materials are more resistant to the chemical additives in today's hydraulic and lubricant fluids (especially the high water base fluids), as well as the chemicals in Table IV.
• Prevention of possible media migration is assured by the spun nylon cover.

EXCELLENT FOR USE IN THE PROCESS, OIL AND GAS, HYDRAULIC AND LUBRICATION INDUSTRIES
