Tube Axial Roof Upblast Fans
Greenheck’s tube axial upblast roof exhausters, both direct and belt drive, are designed to efficiently remove
and disperse contaminated air. The upblast configuration is ideal for exhausting contaminants away from a
building to prevent roof damage and re-entrainment of exhaust air.
Greenheck’s versatile tube axial design can be used in most commercial and industrial applications. Typical
applications include:
• General exhaust
• Industrial space ventilation
• Fume hood exhaust
• Paint booth exhaust

Powder coatings offer a uniform, durable, and high quality finish. Powder
coating is a one-coat process applied over a phosphatized surface that
generally meets or exceeds the corrosion resistance of a comparable wet paint.
Greenheck offers a number of in-house coatings applied via electrostatic
powder. The standard coating, Permatector™, is excellent for indoor or outdoor
applications and is resistant to many common chemicals. For information on
our complete offering of coatings, visit geenheck.com and navigate to Library/
Application Articles. Search for Performance Coatings for Ventilation Products
for a comprehensive listing of coatings and a relative resistance chart.
