Trail Breeze™ / eleVENT™ Modular Window Vent System
Universal Dual-Opening Front Window Vent for Heating, Cooling, and Ventilation
The Trail Breeze™ / eleVENT™ Modular Window Vent System is a vehicle-specific front roll-down window insert designed to give you maximum flexibility for airflow, climate control, and accessory integration — all through a single, modular vent platform.
Installation is simple and fully reversible: roll the front window down, place the window plate into the opening, then raise the window to hold the assembly securely in place. No drilling, cutting, or permanent vehicle modification is required.
Estimated lead time: Approximately 2 weeks
How the System Works
Each Trail Breeze / eleVENT window plate features two independent vent openings.
- Each opening can be configured separately
- Inserts and adapters may be mounted on the interior or exterior side of the vehicle
- All inserts and adapters use the same universal vent interface
This allows you to mix and match inserts and adapters for heating, cooling, or passive ventilation — now or in the future — without ever replacing the window vent itself.
The system may be installed on either the driver-side or passenger-side front window and is fully removable when not in use.

Optional Adapter Kits (Most Common Setups)
For customers using portable AC units or heaters, the following complete adapter kits may be added at checkout for the most common configurations:
- 🔥❄️📦 EcoFlow Wave 2 / Wave 3 Dual-Hose Kit
Allows one opening for intake and one for exhaust. Hose direction depends on whether the unit is placed inside or outside the vehicle. - ❄️📦 ZeroBreeze Mark 3 Adapter Kit (4″ + 5.5″)
Required kit for ZeroBreeze Mark 3 units using two different hose sizes. - ❄️📦 ZeroBreeze Mark 2 Adapter Kit (Dual · 4″)
For ZeroBreeze Mark 2 dual-hose systems.
Common Single Adapter
- 🔥 Diesel Heater Adapter (Single · 3″)
A common first-purchase option for diesel heater users. One adapter is used per hose (most diesel heater setups use a single hose).
Adapter OD Reference
| Adapter Type | Nominal Size | Adapter OD |
|---|---|---|
| 3" Clamp Adapter | 3″ | 2.98″ |
| 4" Clamp Adapter | 4″ | 3.875″ |
| 5" Screw-Connect Adapter (ZY.Hyisinn) | 5″ | 4.93″ |
| 5" QC Adapter (EcoFlow) | 5″ | 5.30″ |
| 5.5" Clamp Adapter | 5.5″ | 5.45″ |
| 6" QC Adapter (EcoFlow) | 6″ | 6.20″ |
Adapter OD values are intentionally slightly undersized to allow hose fitment.
Clamp-on and slip-fit adapters are typically ~0.05–0.15″ smaller than nominal hose size.
EcoFlow QC adapters taper past the retention ring and are designed for quick-connect couplers.
Clamp fitment may be limited.
