This is the interior sealing shutter for a 36" wall-mounted evaporative cooler. It rolls open automatically when your fan powers on and seals the wall opening shut when the fan shuts off, so you're not paying to heat or cool the air leaking through an idle fan opening.
The RollSeal Shutter is built for repeated open/close cycling in commercial and industrial settings, where a wall opening left uncontrolled means wasted conditioned air, weather intrusion, and pest access. Pairing it correctly with its wall-mount fan and mounting kit keeps the whole system airtight when idle. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fitment & Requirements
- Size: 36-inch shutter, matched to the 36" SS Pro - Wall Mount Model (6622-7001) wall opening.
- Installation location: interior building wall only.
- Requires the 36" SS Pro - Wall Mount Model (6622-7001) and Wall Mounting Kit (6540-1060), both sold separately — this shutter does not function as a standalone unit.
- Control: included control unit with automatic mode (wired to fan controller) and manual mode selection.
- Does NOT fit evaporative coolers other than the 36" SS Pro - Wall Mount Model; no compatibility confirmed with other PolarCool sizes or other manufacturers' wall-mount fans.
- Not designed as an exterior-mounted component — it is an interior shutter, not a replacement for the exterior wall mounting kit.
Key Benefits
- Automatic mode syncs shutter operation directly with the evaporative cooler fan controller.
- Manual mode gives you independent shutter control for ventilation or maintenance access.
- Rolling design built for repeated open/close cycling in commercial and industrial environments.
- Tight seal on closure helps block weather, pests, and unwanted air exchange.
- Interior mounting location protects the shutter mechanism and simplifies service access.

- Does NOT fit: evaporative cooler wall openings sized differently than the 36" SS Pro - Wall Mount Model.
- Does NOT function without both required companion parts (36" SS Pro fan and Wall Mounting Kit) — this shutter alone does not complete a wall-mount installation.

FAQ
Will this shutter fit any 36-inch wall-mounted evaporative cooler?
No. It is sized to match the wall opening of the 36" SS Pro - Wall Mount Model (6622-7001) only. It is not confirmed to fit other brands or other PolarCool models.

Yes. This shutter requires the 36" SS Pro - Wall Mount Model (6622-7001) and the Wall Mounting Kit (6540-1060), both sold separately.
Can I run the shutter manually instead of automatically?

Where does the shutter mount, inside or outside the building?
The RollSeal Shutter installs on the interior side of the building wall, giving you protected operation and easier access for maintenance.
What does the shutter protect against when the fan is off?
When closed, it helps block air infiltration, rain, wind-driven debris, and pest entry through the wall opening.
