High Temperature

Rosedale HT Series Meta Aramid Filter Bags are constructed of synthetic fibers that are extremely heat resistant.  They can be used in applications to withstand intermittent temperatures as high as 464F/240C or continuous to 400F/204C. 

Using a proprietary combination of fiber diameters, weights and thicknesses, HT Bags are an efficient depth filter media. To reduce fiber migration HT bags are glazed. For applications within the range of polyester (300F), the Rosedale RPE Flange top can be attached to provide an optimum seal. They are supplied with sewn seams, 1 to 200 microns with a nominal efficiency of 90%.

Oil Absorbing - OA & OS

Our OA bag is ideal for removing trace oils and grease from coolants, waste water and many aqueous-based fluids. The OS filter bag is made of Rosedale’s proprietary polymer media providing for up to 10 times the hydrocarbon adsorption of OA Bags. They are used for many hydrocarbon adsorption applications and the OS Filter Bag is capable of removing free and dispersed oils as well as oil emulsions.

OA and OS are multi-layered bags manufactured with a media migration barrier and include reinforced lift handles to facilitate removal. They are rated at 25 microns.

Graded Density

Our Graded Density series of filter bags meets the most stringent needs for today’s water, fine process,  lubricant, food, and beverage filtration. Made of unique microfiber materials, they’re designed to increase the efficiency and dirt-holding capacities of the filter bag.

  • Operates on the principle of depth filtration
  • Filter grades of 1, 3, 8 and 19 microns @ 95% efficiency
  • GD Bags are 100% polyester or polypropylene for excellent chemical compatibility
  • FDA compliant to meet food grade government standards

Beta Rated Bags

Rosedale Beta Bags® are unique multi layer filter bags made of polyester microfiber and encased in a spun-bonded media migration barrier. Evaluated by the ISO 4572 multi-pass test method, Beta ratings offer a true indication of performance throughout the life of the filter. This is significant because many filter ratings are based on initial efficiencies only. Beta Bags provide real ratings for the real world.

  • Beta Bags® are 100% polyester for excellent chemical compatibility.
  • All Beta Bags are available with Rosedale’s superior sealing RPE style flared top flange or as a ring type filter bag.
  • Prevention of possible media migration is assured by the spun-bonded cover.

XTND Filter Bags

XTND Filter Bags Offer Additional Surface Area for Increased Filtration Efficiency

Our XTND filter bag is a balance between increased efficiency and capacity versus cost.  XTND filter bags offer 3 times the life of a standard bag.  The flexible RP series plastic collar makes installation and disposal easier, as there is no metal to worry about. These bags are excellent for pre-filter and depth filter applications. If you’re looking for the ideal pre-filter or depth filter bag, try an XTND filter bag.

Requires a XTND Basket.

Bag Sized Pleated Cartridges

These elements are easily installed in standard housings combining the best features of filter bags and cartridges into one single unit. Like bags they’re easily handled and trap contaminant internally to prevent “wash off”. 

Like cartridges they provide greater surface areas and increased dirt holding capacities over a standard bag. 

Special Application & Compatible Filter Bags

Rosedale Products Europe not only offer ranges of filter bags to suit Rosedale Housings. We are pleased to offer specialist manufacturing services for customised requirements and compatible patterns to other manufacturers designs. Our current portfolio extends to:

  • PALL / FSI
  • Eaton
  • Strainrite
  • Micron Technologies

Filter Bag Solutions

Filter bags can be the ideal solution for your industrial filtration application needs. They are designed to remove contaminant and debris from liquids and the dirt is caught inside the bag. Other filter technologies collect the solids on the outside of the device giving it the potential to dislodge into the filter upon removal. Filter bags keep the clean side of the filter that way, clean. The amount and size of contaminants the filter bags remove depends on their specific micron rating.

Filtration Levels for Filter Bags

Rosedale offers many levels of filtration to meet application criteria. We offer low-cost, standard efficiency filter bags and high-efficiency, high-capacity elements. Our standard capacity elements usually have about 4.4 square feet of surface area, holding approximately a pound of contaminant, perfect for many applications.

The filter bags we offer for this level of filtration include our standard filter bag, the Beta Bag®, and our RPO plastic top, self-sealing bag filter. These filter bags fit our standard side inlet housings.
