PolarCool 36" RollSeal Shutter (Part No. 6621-0300-HH)
Complete your wall-mounted evaporative cooling system with the PolarCool 36" RollSeal Shutter, an automated interior shutter designed to maximize energy efficiency, climate control, and protection when paired with the 36" SS Pro - Wall Mount Model (6622-7001) and Wall Mounting Kit (6540-1060).
This intelligent shutter features automatic mode that opens when your evaporative cooler powers on and seals tightly when the fan is off, plus manual control for independent operation. The shutter helps prevent air infiltration, maintain building temperature control, and protect your facility from weather and pests.
Why Shutters Are Essential for Wall-Mounted Fans
Energy Efficiency – Opens the full fan area when in use and tightly seals the opening when not in operation, preventing unwanted air exchange that wastes energy.
Ventilation Control – Allows fresh air to circulate when the evaporative cooler is operating, then stops air movement when cooling is not needed.
Weather Protection – Helps keep rain, snow, wind, debris, and other outdoor elements out of the building when the fan is not running.
Pest Prevention – Sealed closure helps prevent insects, rodents, birds, and other pests from entering through the wall opening.
Automatic or Manual Operation – Choose automatic mode for hands-free operation synchronized with fan controls, or manual mode for independent shutter control.
Climate Control – Helps maintain building temperature by preventing cold air infiltration in winter and hot air infiltration in summer when the evaporative cooler is off.
How the RollSeal Shutter Works
The 36" RollSeal Shutter integrates with your wall-mounted evaporative cooling system and gives you flexible control options for daily operation, seasonal use, ventilation, and maintenance.
Automatic Mode:
- Shutter opens when the 36" SS Pro - Wall Mount Model powers on
- Allows full airflow from the evaporative cooler into the facility
- Rolls closed when the fan shuts off
- Creates a tight seal over the wall opening
- Wires through the fan controller for synchronized operation
Manual Mode:
- Allows independent shutter control regardless of fan operation
- Useful for ventilation without cooling
- Helpful for maintenance access or specific operational needs
- Provides flexibility when shutter control needs to be separate from fan operation
Complete Wall-Mount System Components
For a complete wall-mounted evaporative cooling installation, three components work together:
-
36" RollSeal Shutter (6621-0300-HH): This product. Automated interior shutter mounted on the inside of the building wall.
-
36" SS Pro - Wall Mount Model (6622-7001): Sold separately and required. Stainless steel evaporative cooler equipped with wall-mount brackets instead of casters.
-
Wall Mounting Kit (6540-1060): Sold separately and required. Metal mounting components that attach the cooling fan to the building exterior.
RollSeal Shutter Features
Automatic and Manual Modes – Includes control unit allowing automatic operation synchronized with fan controls or manual independent control.
Tight Sealing – Creates an effective seal when closed, helping prevent air infiltration, weather penetration, and pest entry.
Rolling Design – Smooth rolling mechanism provides reliable operation cycle after cycle.
Interior Mounting – Installs on the inside of the building wall for protected operation and easy maintenance access.
Durable Construction – Built for repeated open and close cycles in demanding commercial and industrial environments.
36" Size – Sized to match the 36" SS Pro - Wall Mount Model opening for proper coverage and sealing.

Benefits of the RollSeal Shutter
Energy Savings
- Helps prevent heat loss in winter
- Blocks hot air infiltration in summer when the cooler is off
- Reduces load on heating and air conditioning systems
- Eliminates wasted energy from uncontrolled air exchange
Climate Control
- Maintains building temperature when evaporative cooling is not in use
- Allows other HVAC systems to operate more efficiently
- Helps reduce temperature fluctuations from open wall penetrations
- Supports more controlled indoor environments
Protection
- Keeps rain and outdoor weather out of the facility
- Helps prevent wind-driven moisture and debris entry
- Blocks pest access through the wall opening
- Protects interior spaces from outdoor elements
Applications
The 36" RollSeal Shutter is ideal for wall-mounted evaporative cooling installations in:
Climate-Controlled Facilities:
- Warehouses with heating systems
- Manufacturing plants with HVAC
- Distribution centers with temperature control
- Food processing facilities with climate requirements
- Facilities operating in multiple seasons
Energy-Conscious Operations:
- Facilities focused on energy efficiency
- Buildings with high energy costs
- Operations seeking to reduce utility expenses
- Green building initiatives
- Sustainability-focused organizations
Protected Environments:
- Food processing and packaging plants
- Clean manufacturing facilities
- Retail spaces requiring climate control
- Facilities with sensitive equipment
- Operations requiring pest control
Wall-Mount System Integration
The RollSeal Shutter completes your wall-mounted evaporative cooling system by sealing the interior wall opening when the fan is not in use. The exterior-mounted 36" SS Pro fan introduces cooled air into the building, while the interior shutter controls the opening from inside the facility.
Coordinated Operation in Automatic Mode:
- Power on controller
- Fan starts
- Shutter opens
- Cool air flows into the building
- Power off controller
- Fan stops
- Shutter closes and seals the opening
Installation Requirements
Required Components for Complete Installation:
- 6621-0300-HH - 36" RollSeal Shutter
- 6622-7001 - 36" SS Pro - Wall Mount Model, sold separately and required
- 6540-1060 - Wall Mounting Kit, sold separately and required
Installation Considerations:
- Shutter mounts on the interior building wall surface
- Must be coordinated with wall penetration size and location
- Wiring integrates with fan controller for automatic mode
- Control unit must be mounted in an accessible location
- Interior wall surface must provide proper mounting support
- Clearance is required for shutter operation
Why the RollSeal Shutter Is Recommended
While the 36" SS Pro - Wall Mount Model can be installed without a shutter, the RollSeal Shutter provides major benefits for year-round building performance, energy control, and facility protection.
Without a Shutter:
- Wall opening remains open when fan is off
- Continuous air exchange through the wall penetration
- Heat loss in winter and hot air infiltration in summer
- Weather and pest access to the building interior
- Increased energy costs from conditioned air loss
With the RollSeal Shutter:
- Wall opening seals when the fan is off
- Controlled air exchange only when cooling is needed
- Improved energy efficiency year-round
- Weather and pest protection
- Other HVAC systems can operate more efficiently
- Flexible automatic and manual control options
Operating Modes Explained
Automatic Mode is best for typical daily operation when you want the shutter synchronized with fan operation. Set the control to automatic mode and the shutter opens when the fan powers on, then closes when the fan shuts off.
Manual Mode is useful when you need independent shutter control, such as opening the shutter for ventilation without running the evaporative cooler, keeping the shutter closed during fan maintenance, testing the system, or meeting special operational schedules.
