Webasto A9 BlueCool A-Series Slimline Air Handler – 9,000 BTU – 230V

Cabins with tight wall clearance or a narrow installation bay get a purpose-built fit in the Webasto A9 Slimline Air Handler, delivering the same 9,000 BTU capacity as the standard A9 Compact in a taller, narrower vertical chassis. This slimline marine air handler is built for mounting in confined spaces where a wide compact unit simply won’t fit.

At just 8.5 inches wide but standing 24.1 inches tall, this configuration trades footprint for height in the opposite direction from the Low Profile line — useful specifically for narrow vertical bays behind a bulkhead or in a tight closet-style installation space where width, not height, is the binding constraint.

Why Choose the Webasto A9 Slimline

This unit carries Webasto’s standard 2-year warranty. If your installation bay is tall and narrow rather than wide and short, this slimline configuration delivers the same 9,000 BTU performance as the compact version in a chassis built to fit.

What to Know Before Installing

• A Webasto A-Series Cabin Control Kit is required for installation — this listing is the air handler only
• Measure your installation bay carefully — at 24.1″ tall and only 8.5″ wide, this unit needs more vertical clearance than the standard compact A9
• This handler requires a matching Webasto chiller (C-Series, V-Series, or VX-Series) as the central cooling source
• Can be extended with an EHM900W electric heat module and flow control valve for independent cabin heating
