Bag Filter Housing Parts & Accessories
National Filter Media is your one-stop shop for all of your filter bag housing accessories. From restrainer baskets to gaskets and O-ring seals, we can help you find what you need to run your filter bag housing efficiently and safely. Our wide range of available accessories can be included as a part of the initial design for your filter bag and cartridge housing, or can be added on later to improve your processes.

Restrainer Baskets
Heavy duty, electropolished 315 stainless steel perforated plate baskets are including with your filter bag housing. They allow use of filter bags and HAYFLOW™ elements up to differential pressures of 30 psi.
Our baskets are available in all standard sizes, filling all Eaton bag filter housings. They can also be made in the material of your choice with options including Hastelloy or epoxy coated. Baskets can be used with adaptor rings for retrofitting other types of housing.
LOFNETIC Magnets
Magnet assemblies are inserted in the filter bag during filtration. They are fitted in the center with magnetic bars and can also be used as a bag positioner. The lifetime of your filter bag housing is extended when LOFNETIC magnets retain magnetic particles such as chips and fines, preventing deposit on the filter media. They also retain finer magnetic dust when using bags of courser micron rating. Eaton magnetic strainers are available in size 01 and 02 using one or two 316 stainless steel covered magnetic bars.
Bag Positioner
Highly recommended for all installations, mandatory for some, bag positioners or “bag locks” ensure correct positioning of the filter bag within the basket and eliminate any bobbing up and down movement of the bag caused by uncontrolled back pressure. This avoids any chance of the bag bursting. They are available in sizes 01 and 02.
Leg Assembly
Height-adjustable leg assemblies are standard for size 01 and 02 TOPLINE™, FLOWLINE™ and SIDELINE™ housings, and optional for ECOLINE™ housings. Wall mounting brackets are also available.
Displacement Balloons
Inserting a displacement balloon inside the filter bag minimizes the amount of residual liquid present in the filter bag and reduces product loss. This eases the changing of the filter bags eliminating the need for expensive pressure-aided draining systems. The 316 stainless steel balloons’ maximum DP is 230 psi. They are available in sizes 01 and 02.
Manifold Modules
Eaton standard pipe modules are available in 316 stainless steel. 90° elbows, flange reductions, flanged “T” sections, and flange manifolds can be easily assembled to make DUOLINE™ or MODULINE™ bag filter versions based on FLOWLINE™, SIDELINE™ or TOPLINE™ size 01 or 02 housings.
Adapter Head for Open Filtration
Used in conjunction with SNAP-RING® filter bags in gravity feed open systems, adapter heads are available in 316 stainless steel and polypropylene with a 1.5-inch NPT connection for pressures to 20 psi.
Gaskets and O-ring Seals
Eaton metal filter housings are fitted with Buna N O-rings. Plastic housings have Viton® O-rings. Other material options such as EPDM, Viton, TFE encapsulated Viton or Silicone rubber are available as flat gaskets. These options offer a variety of chemical and thermal resistances for many different applications.
Mesh Strainers
Bag filter housings may be fitted with 316 stainless steel mesh lined strainers in place of baskets to convert them to strainer filters. Mesh strainers are available in four standard sizes: 01, 02, 03 and 04, micron ratings are 25, 50, 100, 150, 250, 400, 800 µm respectively.
Bag Hold-down Rings
Bag hold-down rings vary by the bag filter housings and are included with the housing upon purchase. They hold the filter bag securely inside the restrainer basket which in turn is positioned correctly within the housing.
