Common Baltimore Aircoil BAC OEM Parts We Stock
BAC Bearings
Bearings are critical fan-drive components on many BAC cooling towers and evaporative heat-rejection products. Replacement selection should be based on the equipment model, serial number, and installed fan-drive configuration.
BAC Basin Heaters and Heater Controls
Basin heaters are used for freeze protection in applicable cold-water basin installations. BAC equipment may also use heater controls and related low-water protection components, depending on the model and factory options.
BAC Electric Water Level Controls and Sensors
Electric water level controls help manage basin makeup water and maintain the intended operating water level. We stock common BAC electric water level control components and sensors for replacement and service work.
BAC Single and Banded Belts
We stock both single and banded replacement belts used in BAC belt-drive fan systems. The correct belt depends on the specific drive arrangement, sheave configuration, and equipment model.
BAC Sheaves and Bushings
Sheaves and bushings are part of the fan-drive assembly and should be matched correctly to maintain proper belt alignment and fan-drive operation. Using the model and serial number helps confirm the correct OEM component.
BAC Vibration Switches
Vibration cutout switches are protective devices used to respond to excessive mechanical vibration. Depending on the BAC equipment and control arrangement, the switch can initiate a shutdown or cutout condition to help protect the equipment.

Frequently Asked Questions About Baltimore Aircoil BAC Parts
What Baltimore Aircoil BAC parts do you stock?
We stock common BAC OEM replacement parts including bearings, basin heaters and heater-related components, electric water level controls and sensors, single and banded belts, sheaves and bushings, and vibration switches. Availability varies by part number.
What information do I need to identify a BAC replacement part?
The best starting point is the BAC model and serial number. An existing part number, equipment nameplate photo, and clear photo of the component can also help confirm the correct replacement.
Does BAC use both single belts and banded belts?
Yes. BAC belt-drive equipment can use different belt arrangements depending on the model and fan-drive configuration. The model, serial number, and existing drive components should be checked before ordering.
What does a BAC vibration switch do?
A vibration cutout switch helps protect rotating equipment by responding when vibration exceeds its set condition. Depending on the control arrangement, it can initiate a shutdown or cutout to prevent continued operation under excessive vibration.
What does an electric water level control do on a BAC cooling tower?
An electric water level control is used to help maintain the proper basin water level by controlling makeup water. The exact components and control sequence depend on the BAC equipment and installed options.
Why is the correct sheave and bushing important on a BAC cooling tower?
The sheave and bushing are part of the mechanical drive system. Correct sizing and fit are important for belt alignment, fan speed, and proper drive operation, so replacements should be selected for the specific equipment configuration.
Can you help identify a BAC part that is not listed online?
Yes. Send us the BAC model and serial number, the existing part number if available, and photos of the equipment nameplate and component. We can use that information to help identify the correct replacement.
