At-A-Glance Features

Each model delivers clean, oil-free air to a wide range of industrial applications.
World-class engineering and design.
Manufactured under rigid ISO 9001 standards by quality craftspersons.
Exhaustively tested to meet strict performance criteria to ensure unequaled service life under the most severe operating conditions.
Available in the 30, 45 and 70 Series with various configurations and rotor lengths.
Horizontal or vertical mounting configuration available for each blower.
Supported by a worldwide network of trained professionals and backed by a manufacturer’s warranty
- 18 months from the date of shipment or
- 12 months from the date of installation, whichever occurs first

Durable

Oversized bearings for added support and greater durability
- Gear-end bearings support rotor shafts, while drive-end double-row angular contact ball bearings fix the rotor position.
- Prevents destructive axial rotor movement commonly caused by misaligned V-belt drives.
Durable single-piece cast iron cylinder with integral ribs
- Provides greater strength and rigidity.
- Ribs improve heat dissipation and prevent distortion that can affect internal clearances reduce performance.
Innovative rotor/shaft design machined from a single, high-strength ductile iron casting and dynamically balanced
- Assures extra strength and rigidity to handle maximum loads on a continuous basis without fatigue, deflection or vibration.

Reliable

Dual Splash Lubrication
- Provides superior gear and bearing lubrication for longer life at all operating conditions.
- Reduces maintenance.
Timing gears are mounted on precision machined shaft splines
- Assures secure non-slip rotor timing even under surge conditions or high torque start-up.

Efficient

Helical timing gears, precision machined from alloy steel forgings
- Guarantees quiet and smooth mechanical operation at all speeds.
Noise Reduction
- Extra cylinder mass and progressive porting aid in reducing noise.
Vertical or horizontal mounting configuration with each blower
- Provides greater flexibility for installing into any new or existing system.

Flex-Mount™ Design Provides Maximum Installation Versatility

Flex-Mount™ Design and available porting connectors provide installation flexibility.
Assures interchangeability of existing installed DuroFlow® models or compatibility as replacement for most competitive models.
Reduces inventory requirements due to machine flexibility.
