Dust, chips, or other process waste is conveyed in an individually layouted duct system. The type of material (steel, stainless steel, aluminium or plastic) and the thickness are adapted to the conveyed material being. Radial fans provide the necessary negative pressure in order to create the conveying current. They can convey the extracted material directly (transport fans) or be positioned on the clean air side behind the separator systems (clean air fans).

Injector systems are used for specialized applications such as transportation of edge trim or the conveying of granules and pellets.

In order to achieve reliable operation and economical conveying speeds, duct dimension and fan parameters need to be well balanced.


What kind of waste and dust are extracted by Krämer systems?

Krämer systems convey and dispose of dust, strip-shaped, and chip-shaped waste.

In which production processes are Krämer systems used, and at which points?

Krämer systems are used in processes where cutting, punching, milling, and planing occur, and where various types of waste are generated during the process: from dust to edge strips, paper and film residues, to punch grids, and cardboard waste.

Can I just get advice from Krämer Lufttechnik initially?

Before making any investment decision in an extraction and disposal system, many questions need to be addressed, such as: What exactly do I need? What is the flow behavior of my waste? How well can the system be used for varying loads? How well can the system be expanded for future needs? Only once these and other questions are answered can the decision to invest be made.

Can operations continue while an extraction system is being installed or an old one is being renewed?

With good planning and preparation, the installation of a new extraction system can take place during ongoing operations. However, it not only depends on good planning but also on the spatial conditions and the entire machinery park that must be connected to the system. If an interruption of production is absolutely necessary, we are quick to respond so that this interruption is as short as possible.
