COMAIR BT2B1 115 V AC case fan
The COMAIR BT2B1 is a 120 mm square frame fan 32 mm thick that runs on 115 V AC mains voltage. It draws 0.19 A at start-up and 0.17 A during steady operation. Double ball bearings support the rotor for long service life in continuous duty. A two-piece socket provides the electrical connection.
Suited for industrial and embedded cooling
This fan fits equipment builders who need a mains-powered axial fan for medical devices, rail vehicles, drive enclosures, hotel systems, industrial cleaning machines, electronic cabinets or new-energy vehicle subsystems. It is not for PC builders who require a 12 V DC fan with PWM speed control or standard motherboard headers. Buyers who need variable speed regulation or lower voltage operation should look at alternative designs.
115 V AC mains voltage decides compatibility
The single specification that determines fit is the 115 V AC supply requirement. Your system must provide mains-level alternating current at this voltage; a 12 V DC header will not drive the motor. Verify that your enclosure wiring and safety approvals accept a mains-connected fan before purchase.

คำถามเกี่ยวกับสินค้านี้
How is the 120 × 120 × 32 mm fan mounted and which step is often missed?
The unit fits a standard 120 mm square cut-out using four corner screws; the step often missed is wiring the two-piece socket correctly for 115 V AC before securing the frame.
What maintenance will the double ball bearing need over time?
Double ball bearings are sealed and require no lubrication; if noise or vibration appears after extended use the entire fan should be replaced.
At what point does the 0.19 A / 0.17 A current draw become a limiting factor during continuous operation?
The 0.19 A start-up and 0.17 A running currents are well within a typical 115 V AC supply; the first practical limit is bearing wear after prolonged continuous duty.
