Webasto A4 BlueCool A-Series Compact Air Handler – 4,000 BTU – 230V

The smallest air handler in Webasto’s A-Series lineup, the A4 delivers 4,000 BTU of cooling capacity for the tightest cabin spaces on a central chiller system. This smallest webasto air handler is sized specifically for heads, small berths, or other compact spaces that don’t need — or don’t have room for — a larger handler.

Starting with the right-sized handler for a small space matters more than it might seem: an oversized handler in a tiny cabin can overcool the room and cycle inefficiently, while the A4’s proportionally lower airflow and chilled water demand are matched to the actual volume of air it needs to move.

Why Choose the Webasto A4

This unit carries Webasto’s standard 2-year warranty, and its 0.6A current draw is minimal enough to add to almost any existing cabin circuit without concern. A cabin control kit is required for installation and sold separately.
