Bag cages are designed and manufactured by Nederman MikroPul in our own plant to ensure the critical and proper fit between the bag and cage for proper sealing and long bag life. The customer receives a single source responsible party able to guarantee emissions performance and bag life. Cages can be made in a wide variety of diameters in both top and bottom load designs. Our cages feature custom metal specifications such as carbon steel, 304 and 316 stainless materials, or coated with Teflon, special paints or varying levels of galvanization. Top load style cages can include an integral venturi, or where toxic materials or operating pressures are of a concern, can be designed with the patented Nederman MikroPul Cam Lock venturi for precise leak free tubesheet connections.


Pop-Top 2.0 Bag & Cage Assembly for Easy Installation: Just Step On It!

Pop-Top™ 2.0 is an innovative two-piece filter bag and cage system that installs in seconds, cutting in half snap-in bag changeout time. Pop-Top 2.0 incorporates an elastomeric collar which makes it more forgiving for holes with tolerance variations or unfinished edges. It is especially suitable for applications such as cement, in which the bags and cages tend to stick together. The unique design eliminates the need for tools or clamps for installation, forming a solid seal every time.

To install, the maintenance employee inserts the bag, inserts the cage, and then steps on the assembly (as demonstrated in top, left photo). With use of a small hand tool, removal is just as easy. Costs are competitive with conventional bags and cages. Pop-Top is for new or existing baghouses.
