Spark pre-separator for maximum safety
Spark pre-separators are used in metalworking, for example, to protect the extraction or dust extraction system from glowing sparks and consequently from fire. Ensure safety with a spark pre-separator from L+M AG to protect people and machines.
The spark pre-separator as part of the extraction system effectively separates sparks before they enter the system.Spark pre-separator
During machining processes in the metal industry, such as grinding, polishing, brushing, cutting and plasma cutting of steel, sparks are produced which can enter the extraction system via the pipe system and cause a fire. A spark pre-separator provides a remedy here and prevents a filter fire.

Spark pre-separator with water labyrinth, ideal for short air paths.
A secure workplace
By using a spark pre-separator, you not only protect your employees, but also your extraction and filter systems and all operating equipment. With our experience and expertise in the use of spark pre-separators, we always find an individual solution with the right performance and functionality. With certainty.
