商品紹介

The tube-axial flow fan uses an aluminum airfoil impeller centered inside a close-clearance galvanized steel cylinder. The blades accelerate air parallel to the shaft, making the fan suitable for large airflow duties where a full centrifugal scroll is unnecessary. An external motor and shaft arrangement leaves the duct bore comparatively open, protects the motor from the conveyed air and gives technicians direct access to the drive without removing the cylindrical casing from the duct.

主要な特徴

Adjustable-pitch airfoil blades allow the impeller to be matched to the required volume and pressure before operation.

A close, even tip clearance reduces bypass at the blade ends and supports repeatable axial performance.

The hot-dip galvanized cylindrical shell resists corrosion and maintains flange alignment under duct loads.

An externally mounted motor and bearing frame keep heat-producing drive components outside the airflow passage.

お客様の製品に関する懸念事項

High-airflow systems need a compact fan with low pressure loss, but poor blade selection or uneven tip clearance can cause noise and reduced output.

A centrifugal fan adds unnecessary footprint and turning losses to a nearly straight low-resistance duct.The axial impeller moves air in the duct direction and fits within the circular passage without a scroll casing.

A fixed propeller cannot be matched closely when the final airflow duty changes during design.Adjustable blade pitch provides a practical way to select the required pressure and volume within the fan size.

Motor heat and dust exposure shorten service life when the motor sits directly in the exhaust stream.The external motor frame removes the motor body from the conveyed air while transmitting power through a protected shaft.

Uneven casing geometry creates variable blade-tip clearance and local turbulence.A rolled and reinforced tube maintains a concentric bore around the balanced aluminum impeller.
