Bag filter accessories improve filtration system efficiency, reduce product loss and enhance safety. They include restrainer baskets, bag positioners, magnetic separators and displacement balloons.

prevent pressurized spray when a bag ruptures during cleaning or removal and are especially important in multi-chamber dust collection systems. They also provide a safer working environment by deflecting the spray away from personnel’s faces. Magnetic Inserts

Many industrial applications rely on magnets to capture ferromagnetic particles and contaminants in liquids. From removing rusty iron and steel debris from cooling tower water to removing corroded iron and steel from pipeline strainers or bag filter housings, using magnetic assembly options can reduce maintenance costs and protect equipment from damage.

While it may seem counterintuitive, magnetic separators can also enhance the performance of bag filters. Specifically, they prevent ferrous fines from clogging the filter bag media. This can significantly reduce the number of filter bags needed annually, resulting in cost savings associated with labor and disposal costs.

These devices are essentially a pair of powerful magnets that are inserted into the filter. They have a specialized coating that increases their magnetic attraction to ferromagnetic metals such as iron and steel. Magnetic separators are typically made from a permalloy (a combination of nickel and iron) or stainless steel that has a high saturation magnetization (28,000 gauss). They are available in a variety of shapes, sizes and designs. Depending on the application, magnetic separators can be configured as plugs or rod magnets that extend from reservoir tops, special filter canisters or the center tube of standard filter elements.

Magnetic separators are able to capture a wide range of particle sizes and types, including metallic impurities that are too small to be captured by conventional filter elements. This is due to the fact that magnetic separators utilize a different mechanism for separation, which is based on the collective influence of size, particle susceptibility and magnetic field gradient, as opposed to the more common method of size-exclusion.

In addition, a single magnet can be used to remove the same type of ferrous particles from multiple fluids, increasing the efficiency of the system. Another benefit is that magnetic separators require no filter element cleaning or replacement, which reduces maintenance costs and downtime.

Another important advantage is the ease with which they can be installed into existing or new systems. In order to install a magnetic separator into a filter, the system must be designed with an appropriate interface for installation. Ideally, this interface should be designed to support filtered connectors that can bond to double over-braid shielded cables and provide electromagnetic interference protection to the connector body and the equipment chassis.
High Capacity Filter Baskets

Basket strainers are an effective way to remove large particles from liquid streams. They contain a cylindrical or spherical body with an inlet and outlet, housing a basket-like straining element with perforations or mesh linings to capture debris while allowing clean fluid to pass through. Industrial strainers protect engines, hydraulics, air and water systems from harmful contaminants, preventing unexpected breakdowns due to clogs. These rugged devices can also be used in automotive applications to filter oil, engine coolant and other fluids.

Our stainless steel 316 basket strainers are made with superior materials, promising corrosion resistance and high capacity filtration. They are easy to remove and clean, and have quick-opening swing bolts. Moreover, their welded joints ensure leakage-free operation and safe operation. They are also durable and highly resistant to pressure fluctuations.

They are available in a range of sizes, and can be used with a variety of media types. The wide range of mesh sizes available allows for precise and uniform filtration, making them ideal for beverage production and other similar industries. They can be purchased in either ridged or ridgeless styles, depending on your particular needs.

A ridged basket features an indentation that runs around the basket near the top, while a ridgeless basket does not. The indentation acts to prevent the inserted bag from becoming dislodged during high pressure conditions. This can reduce maintenance downtime and costs by preventing bag rupture during cleaning.

Designed to increase the filtration surface area of existing or new filter housings, our high capacity filter bags can double the flow rate of a standard size basket. This is achieved by placing the bag inside a stainless steel filter basket that has an inner support core, increasing the overall rigidity and intensity of the basket. The bag also reduces the volume of retained liquid by 30%, lowering the filter removal weight and reducing product wastage. This translates into a cost-efficient upgrade for your existing or new filtration system. You can also choose from a range of extended life materials, including polypropylene and polyester.
Displacement Balloons

Bag filter systems are widely used in industrial processes for removing suspended solids from liquids, including food products, paints and coatings, and various chemicals. Typically, these bags are constructed from polypropylene or polyester that is either sewn or welded to form the filter media. When a standard size #2 filter bag is full it can contain up to 4.2 gallons of unused product liquid. This unused liquid is known as carry-out. Displacement balloons are a metal, stainless steel accessory that takes up this unused liquid inside the filter bag to reduce process losses and improve ergonomics.

In the present study, an IAB was filmed in a compliant tube and its diameter (D) and pressure pulse (PPi) were recorded at different locations along the longitudinal section of the balloon. The data were analyzed to determine the volume displaced by the IAB during inflation and deflation and normalized to the nominal balloon volume. These values were then compared between the horizontal and 45deg operating positions.

The results showed that D increased first at the base of the IAB and then at the center, while PPi decreased from the base to the tip of the IAB in both operating positions. Furthermore, at a 45deg operating position, the IAB inflated more rapidly and had a shorter duration of the deflation pulse than in the horizontal position.

This difference can be explained by the fact that at a 45deg angle, the IAB had more free radial displacement of its volume in the upstream direction, whereas in the horizontal position it was limited. The result from the study can be easily applied to any filter system by repositioning the IAB in the desired operating position. This could also help to reduce product loss and improve ergonomics by reducing the force required to lift the support basket of a clogged filter bag. A further benefit is that the unused product liquid is internally drained and not discharged to waste lines thereby reducing treatment chemicals and associated disposal costs. This can also reduce the number of backflushes needed to restore a filter bag to its original working capacity.
Splash Guard

Splash guards are not only designed to protect the area behind your filter housing, but they also suck in engine oil, coolant, power steering fluid and other liquids that leak from the vehicle. This helps reduce environmental and road safety risks associated with leaking fluids.

These are a requirement for some bag filter housing designs. They lock in-place on the bag restrainer basket and are compressed by a springy handle, ensuring a positive concentric seal against the bag and housing. This prevents particulates from bypassing the bag and helps ensure the filtered product will be retained in the filter bags.

This is a safety accessory designed for FLOWLINE and FLOWLINEII bag filter housings. It deflects pressurized spray and splashes of filtered liquid away from the eyes and faces of operators. Splash guards are helpful for preventing injury when a broken seal, spike in line pressure or the failure to relieve system pressure prior to servicing a filter bag vessel causes sudden spray and splash of fluid.

When repairing or replacing a splash shield, it is important to use a suitable adhesive to bond the material. Contact cement or epoxy work well for small cracks and areas of damage. These types of adhesives do not have the strength to withstand exposure to chemicals and other harsh conditions that can be found in a typical industrial setting.
