Fiberglass Fan (FRP)

fiberglass frp fanA few options are available for corrosive applications, but fiberglass fans are a common solution.

Fiberglass, or FRP (fiber-reinforced plastic), is a composite material of a polymer matrix reinforced with glass fibers.

Fiberglass’s corrosion-resistant properties are wide-ranging and suitable for use across the pH scale. In addition to its corrosive properties, fiberglass provides a lighter and more cost-effective alternative to its metal counterparts.

FRP Fan Applications and Operating Limitations

Fiberglass fans and blowers are available in common configurations including axial, centrifugal, radial, and pressure blowers for general or process ventilation applications.

Standard general-purpose resin handles a wide chemical range, with specialized resins and coatings available for extreme applications. Operating temperature limits range from below 100°F to above 200°F, depending on airstream chemistry. FRP fans are restricted to gaseous streams as abrasive solids will cause premature wear.

FRP construction excels in corrosive environments where traditional materials fail rapidly. The plastic composite resists corrosive gases and mists that accelerate equipment degradation, providing extended service life in toxic applications.

Corrosive environments typically contain:

  • Ammonia – NH3
  • Hydrochloric Acid – HCl
  • Chlorine – Cl
  • Nitric Acid – HNO3
  • Hydrogen Sulfide – H2S
  • Sulfuric Acid - H2SO4

How are FRP axial fans constructed? FRP axial fans are built with fiberglass-reinforced plastic components coated in fire-retardant resin. They feature corrosion protection through airtight enclosures or external air circulation, sealed shafts, exterior lubrication lines, and motors isolated outside the airstream on epoxy-coated steel bases.

Benefits of FRP Fans

  • Produced with corrosion resistant materials that are designed to withstand the most severe production environments.
  • Production fans are tested & balanced to ensure reliability.
  • Motor and blade match to deliver consistent, dependable air flow with a wide range of static pressure ratings.

Difference between FRP, PVC & PP

Three plastic composite options are available for corrosive applications: FRP (fiberglass-reinforced plastic), PVC (polyvinyl chloride), and PP (polypropylene).

FRP offers the highest performance, handling the most severe applications with superior temperature and pressure capabilities plus the widest chemical compatibility. Reinforcing fibers provide maximum structural strength.

PVC suits moderate corrosive applications but has lower pressure, temperature, and environmental limits compared to FRP.

PP works for lighter-duty corrosive applications with additional restrictions on size, air volume, pressure, and operating conditions.

Types of Axial Fiberglass Fans

Fiberglass axial fans are available in both belt and direct drives. Each style is suitable for various corrosive applications. Fans are ABS & AMCA certified.

How are FRP Axial Fans Constructed?

FRP axial fans feature fiberglass-reinforced plastic construction with fire-retardant resin coating. Critical components (bearings, drives, shaft) are protected from corrosion through airtight enclosures or external fresh air circulation to prevent corrosive fume contact.

Maintenance features include gasketed access panels for inspection, shaft seals to prevent fume escape, and external lubrication lines for bearing service. Properly sized shafts and bearings extend service life, while motors are isolated outside the airstream on epoxy-coated steel bases.
