Overview
The Webasto Air Flow family is a range of fully electric PTC air heaters developed for electric light commercial vehicles (e-LCVs). Designed for small to medium-sized electric vans, the modular units supply zoned heating capacity with compact installation dimensions.

Key benefits

• Flexible & scalable: 0.7 kW modules can operate standalone or be combined to obtain 1.4 kW or 2.1 kW outputs; supports central or individual zone control.
• Durable PTC technology: Self-regulating element provides reliable heat generation with low maintenance requirements.
• Safe operation: PTC self-limiting behavior keeps surface and outlet temperatures at moderate, safe levels.
• Smart control options: Settings accessible via digital display; mobile app control planned (Q3 2026) with timer, night mode and frost protection.
• Power and voltage options: Multiple voltage configurations and three power output options to fit varied vehicle requirements.
