Exhaust Fan Motor Kits

Exhaust fan motor kits include replacement motor packs and conversion components used to maintain compatible exhaust fan installations or add powered operation to ventilation shutters and combination louver/dampers. Facility maintenance teams can use these components when servicing designated fan models or converting gravity-operated ventilation equipment for motorized opening and closure.

Exhaust Fan Motor Kits: Replacement and Conversion Components for Ventilation Equipment

Exhaust fan motor kits cover two main needs: replacing worn motor packs in existing powered fans and converting gravity-operated shutters or louver/dampers to motorized operation. Whether you're servicing a specific fan model or upgrading manual ventilation equipment, matching the right kit to your exact equipment type is the critical first step.

What These Products Are For

Replacement and Conversion for Exhaust Ventilation Systems

Motor kits serve facility maintenance teams replacing failed motor packs in designated exhaust fan models or converting gravity shutters and combination louver/dampers from manual to powered operation. They restore function to existing equipment or add motorized open/close capability where only passive ventilation existed before.

How To Choose

Match the Kit to Your Equipment Before Ordering

Start with your equipment type and model number. Motor packs are model-specific, shutter kits are designed for either single-panel or double-panel gravity shutters, and louver/damper conversion kits are a separate category. Confirm voltage compatibility and check component dimensions before finalizing your selection.

Common Applications

Where These Kits Are Typically Used

Common applications include servicing Models 411 and 611 exhaust fans, maintaining ACL-F 54-inch and 60-inch fan installations, and converting 556-SP or 556-DP gravity exhaust shutters to powered operation. Louver/damper conversion kits are used wherever manual damper operation needs to be replaced with motorized control.

Additional Information

Power-Open Operation and Fail-Safe Closure

Many shutter and damper conversion kits are designed for power-open operation with automatic closure when power is lost, providing a built-in fail-safe. Selected kits ship as complete field-installation packages including a motor, bracket, linkage, and all required mounting hardware.

Models 411 & 611Supported Fan Models

Motor packs are available for specific exhaust fan models, including Models 411 and 611, so confirming your model number before ordering is essential.

54" & 60"ACL-F Fan Sizes Covered

ACL-F series motor packs are available for both 54-inch and 60-inch fan configurations to match larger exhaust fan installations.

24–240VVoltage Range Available

Selected kits support a wide input voltage range, with options spanning 24–240V and 100–240V at 50/60 Hz for flexible installation compatibility.

Single & Double PanelShutter Kit Configurations

Gravity exhaust shutter conversion kits are available for both 556-SP single-panel and 556-DP double-panel shutter models.

Planning Guide

Plan the right fit before choosing

Planning Guide

Step 1: Identify Your Equipment Type and Model

Before selecting a kit, confirm whether you need a motor pack for an existing powered exhaust fan, a shutter conversion kit for a gravity exhaust shutter, or a louver/damper conversion kit. Each category uses different components and is not interchangeable. Have your equipment model number available.

  • Motor packs are available for specific fan models including Models 411, 611, and ACL-F 54-inch and 60-inch units
  • Shutter kits are designated for either 556-SP single-panel or 556-DP double-panel gravity exhaust shutters
  • Louver/damper conversion kits are a separate product type designed to add powered operation to manual combination louver/dampers
Planning Guide

Step 2: Confirm Voltage Requirements and Physical Dimensions

Check the voltage range listed for each kit against your facility's power supply. Available ranges include 24–240V and 100–240V, 50/60 Hz configurations. Also review component dimensions listed in the product details to plan for handling, clearance, and installation access before the kit arrives on site.

  • Verify input voltage compatibility before ordering to avoid installation delays
  • 50/60 Hz ratings indicate suitability for both standard US and international power frequencies
  • Dimension data helps confirm the replacement or conversion components will fit within the existing equipment footprint

Step 3: Review Kit Contents for Field Installation Readiness

Some kits include everything needed for a complete field installation: motor, mounting bracket, linkage hardware, and fasteners. Confirm kit contents in the product listing so you know what additional materials, if any, need to be sourced separately before scheduling the installation.

  • Complete conversion kits typically include motor, bracket, linkage, and mounting hardware
  • Partial kits or motor-only packs may require existing hardware to be reused or sourced separately
  • Review installation documentation for the specific kit to estimate labor and tool requirements
FAQ

Common questions before buying

How do I know which motor kit is compatible with my exhaust fan?

Start with your fan's model number. Motor packs are model-specific, so compatibility is determined by the exact fan model, not general size or voltage alone. Check the product listing for the model numbers each kit supports before ordering.

What is the difference between a motor pack and a shutter conversion kit?

A motor pack replaces the motor assembly in an existing powered exhaust fan. A shutter conversion kit adds motorized operation to a gravity exhaust shutter that previously opened and closed by airflow alone. They serve different equipment types and are not interchangeable.

Do shutter and damper conversion kits include all the hardware needed for installation?

Selected kits include a motor, mounting bracket, linkage, and mounting hardware for a complete field installation. Always review the kit contents listed in the product details to confirm what is included before scheduling installation work.

What happens to a converted shutter or damper if power is lost?

Shutter and damper conversion kits with power-open operation are designed to close automatically when power is lost. This fail-safe behavior means the shutter or damper returns to a closed position without manual intervention during a power interruption.
