MKFFUW / INRFUW

The MKFFUW and INRFUW are spark extinction systems designed to prevent ignition of downstream filter media in grinding, abrasive cutting, and other processes that generate sparks or hot particles. A spark detection and suppression stage intercepts sparks before they reach the filter unit, protecting the filter from fire risk. The MKFFUW is a module-format unit while the INRFUW is an inline design for integration into central duct systems.

Product OverviewManufacturer Reference
Spark ExtinctionModule & Inline Formats

Applications

  • Angle grinding and abrasive cutting with downstream filter units.
  • Metal cutting processes producing hot particles or sparks.
  • Any extraction system where spark ingestion poses a filter fire risk.
  • Central extraction serving mixed-process areas with occasional grinding.

Key Features

  • Spark detection and suppression stage protects downstream filter media.
  • MKFFUW module format and INRFUW inline format available.
  • Designed for integration with standard Fuchs filter units.
  • Reduces fire risk in grinding and metal cutting extraction systems.
  • Allows use of standard filter units in applications that would otherwise require spark-resistant designs.

MKFFUW / INRFUW

The MKFFUW is a module-format spark extinguishing unit that installs between the extraction capture point and the downstream filter unit. The INRFUW is an inline duct-mounted version for central extraction systems. Both units use physical suppression (water mist or mechanical interception, depending on configuration) to extinguish sparks before they enter the filter.

Formats MKFFUW (module) / INRFUW (inline duct)
Application Grinding, abrasive cutting, metal cutting
Integration Installs between extraction point and filter unit

Selection Notes

  • Select MKFFUW for standalone workstation use where a module-format unit is preferred.
  • Select INRFUW for integration into central duct systems serving multiple extraction points.
  • Required whenever grinding or spark-generating processes share an extraction system with filter units.
  • Contact Pantron Automation for sizing and configuration guidance specific to your application.

Integration Notes

  • Position the spark extinguishing unit between the extraction point and the filter unit.
  • Confirm duct sizes and connection types before ordering.
  • Review maintenance requirements (water supply, drain, or mechanical cleaning depending on type) during installation planning.
  • Contact Pantron Automation for full technical specification and ordering information.
