Small-flow high-pressure fan

Type TBA and TBR fans from Moudi general Fan &Blower are constant pressure, variable volume blowers. Turbo pressure blowers are generally used in applications for relatively low volumes and high pressures. They are used primarily for handling air, gas, and fumes rela-tively free of dust and materials.Moudi general Fan & Blower's TBA and TBR turbo blow-ers provide uniform pressure through the operating range.Stable operation can be maintained from free delivery to shutoff by throttling at the discharge.The design volume of a particular fan can be varied by selecting one of the various wheel options that will fit within the housing.

Wheel Construction

All wheels are made with care to insure maximumstrength and reliability. Wheels have a self-centering,all steel taper-lock bushing. Lock screw holes are provided for positive convenient wheel removalwithout special tools. Wheels are statically and dynamically balanced on the most modern electronic equipment.Every blower unit is given a final running mechanical test and trim balance before shipment.

TBA (Turbo Pressure Air Handling Blower)

The turbo air handling wheel is a moreefficient type of wheel and is used for relatively high volumes of air. The wheel is constructed with heavy-gauge, back wardly inclined blades welded to a spun cone and heavy-gauge backplate. The backplate uses a taper-lock hub for easy wheel removal and self-centering reinstallation. The TBA wheel is generally suitable for clean air applications.

TBR (Turbo Pressure Radial Blade Blower)

The turbo radial bladed wheel is designed for lower air volume at high pressures. The radial blades pro-vide stable airflow over a wide range of airflows. The all-welded wheel uses a taperlock hub for easy removal and self-centering reinstallation. The TBR wheel is generally suitable for clean air applications.

Housing Construction

The turbo blower housing is constructed of continu-ously welded steel with reinforcement as required tomaintain shape and prevent vibration at operating pressures. The housing design provides for wheel removal on the inlet side. The turbo blower also fea-tures a solidly welded steel motor pedestal with heavy plate and angle bracing for positive alignment and smooth operation.
