Machine scraper MDH series

Product overview
MDH-Coil scrapers, also referred to as pneumatic dust seals, are sealing components designed to prevent ingress of contaminants (dust, dirt, moisture) into moving parts of pneumatic systems. They are typically fitted on pistons and rods in cylinders to protect internal components and support reliable operation.

Key functions

• Prevent contaminant entry:
  • Provide a barrier that stops dust, dirt and particles from entering the pneumatic cylinder or system.
  • Protect internal components from abrasion and damage caused by foreign particles.
• Extend equipment life:
  • Reduce the risk of contamination-related wear or corrosion, helping to prolong component lifetime.
• Maintain system efficiency:
  • Help ensure smooth operation by keeping pneumatic circuits clean and free from obstructions.
• Reduce downtime and maintenance:
  • Limit premature seal and component failures, decreasing maintenance frequency and system downtime.
• Support environmental sealing:
  • Offer protection against humidity, splashes or certain chemicals depending on selected material.

Applications

• Industrial machinery:
  • Pneumatic actuators, cylinders and valves in manufacturing equipment and automation systems.
• Construction equipment:
  • Heavy-duty pneumatic tools and machines operating in dusty or harsh environments.
• Automotive:
  • Pneumatic systems in brakes, suspensions and automated assembly lines.
• Medical devices:
  • Pneumatic components where cleanliness and precision are required (e.g., hospital beds, surgical tools).
• Food & beverage:
  • Pneumatic cylinders in packaging, bottling and processing where hygiene is critical.
• Aerospace & defense:
  • Pneumatic systems for aircraft controls and other sensitive applications.

Conclusion
MDH-Coil pneumatic dust scrapers are essential for protecting pneumatic systems from contaminants and preserving performance, reliability and longevity. Selecting the right material and design is necessary to meet specific application requirements.
