Fan blade abrasion protection | Industrial blowers & ventilators | MetaLine

High-velocity air streams carrying dust, sand, fibres or bulk particles form an extremely abrasive mixture. Severe wear occurs particularly at leading edges, blade tips and housings where particle impact velocity is highest.

Material loss results in imbalance, efficiency reduction and increasing vibration levels — often leading to premature bearing failure or costly shutdowns. Conventional hard coatings or metallic armouring frequently fail due to brittleness, excessive weight or complex blade geometries.

MetaLine elastomeric coatings provide a lightweight, energy-absorbing protective layer. Instead of deflecting impact energy, the rubber-like surface absorbs it and stabilizes rotor operation while maintaining aerodynamic performance.

Ask us about:
• fan blades / housings
• ventilator rotors
• industrial blowers
• dust extraction fans
• separator wheels
• propellers / impellers / rotors

Scope of application:
• axial and radial fan blades
• ventilator housings
• industrial blowers
• dust extraction systems
• separator blades
• propellers / impellers / rotors

MetaLine Series 700 – MetaLine Series 700 offers an elastomeric heavy-duty wear protection system with a density as low as 1.05 g/cm³ (0.04 lbs/in3) - you will not find anything weighing less. Energy losses owing to excessive weight or time-consuming balancing are no longer an issue. Due to their electrical insulator characteristics the materials are, however, not permitted in Atex areas (ATmosphères EXplosibles).

Technical solutions in detail

MetaLine Series 700 –

MetaLine 785 is an elastomeric, high-performance erosion protection system with a density of just 1.05 g/cm³ (0.04 lbs/in3) – physics can hardly get any lighter! Energy losses due to the extra weight are a thing of the past. Depending on the local wear, the coating can be applied seamlessly in different thicknesses. More where more is needed – and the rest thinner!

The MetaLine 795 additionally develops an anti-adhesive property that counteracts caking of the conveyed medium! Authorized for flow velocities up to 70 m/s (230 ft/s). 

Due to the electrical insulating properties, the MetaLine 700 series materials are not permitted for Atex areas (ATmosphères EXplosibles). They must always be applied over the entire surface. Partial coating, e.g. only of the profile entry edges, is not effective. Neither are continuous operating temperatures of over 70 °C (160 °F)!
