Twin City Fan & Blower Co. Blower Fan Size: 135 2 Hp Motor 1775 RPM 230/460V, 3 ph P/N: 112342-0261 Type: BCV Class 2 S/N: 01-166216-1-1

Unit Specifications: Size 135 BCV

• Manufacturer: Twin City Fan & Blower (TCF)
• Type: BCV (Belt Driven Centrifugal Utility Set)
• Wheel Type: Backward Inclined Flat Blade (Non-overloading)
• Size: 135 (Indicates a 13.5-inch nominal wheel diameter)
• Class: 2 (Built for higher static pressures and tip speeds than Class 1)
• Motor: 2 HP Industrial Motor
• Speed: ~1775 RPM (Standard 4-pole motor speed, usually reduced via belt drive)
• Electrical: 230/460V | 3-Phase | 60Hz
• Construction: Heavy-gauge welded steel housing (Class II units typically feature continuously welded housings)

Performance Estimates

Because this is a Class 2 unit, it is engineered to handle more "aggressive" static pressures than a standard utility set.

• Airflow Capacity: Typically ranges from 1,200 to 2,800 CFM depending on the static pressure (SP) it is working against.
• Static Pressure: Capable of operating efficiently up to 4.0" – 5.0" w.g. (water gauge), whereas Class 1 units often peak at 2.5" – 3.0".
• Temperature Rating: Standard construction is rated for up to 300°F. (If equipped with a shaft cooler/heat gap, it can go higher).

Key Features of the BCV-135

1. Non-Overloading Design: The backward-inclined wheel ensures that the motor will not burn out if the system's static pressure drops (i.e., if a duct is removed), as the horsepower curve flattens out at higher volumes.
2. Adjustable Performance: Being a belt-driven (BCV) unit rather than direct-drive (DCV), you can change the fan speed by swapping the pulleys (sheaves), allowing you to "dial in" the exact CFM needed for your shop.
3. Rotatable Housing: The discharge can typically be rotated to any of 8 standard positions (Upblast, Top Horizontal, Bottom Horizontal, etc.) to fit your ducting layout.
4. Compact Footprint: Utility sets like the 135 are designed to be "self-contained," meaning the motor, drive, and fan are all mounted on a single pedestal, making them easy to install on rooftops or equipment pads.
