Truma Aventa Ducted Ceiling Assembly Filter 40091-01073

Key features

• Weak airflow or a musty smell from your Aventa vents often means the return-air filter is clogged; this fresh foam element restores unrestricted airflow and keeps dust and pollen out of the AC coil during your annual service.
• Purpose-built for the Truma Aventa Ducted Ceiling Assembly (part 40091-01073) used in ducted rooftop AC installs on campers, caravans, and motorhomes; check your ceiling assembly model before ordering, as filter sizing is system-specific.
• Tool-free replacement: peel the backing off the pressure-sensitive adhesive (PSA) strip and press the foam filter into the ceiling assembly's return-air slot; one filter per package, ready to install in under a minute at each annual filter change.
• Made from 30 PPI (pores per inch) open-cell polyurethane foam that traps dust and debris while maintaining high airflow; this is a single-use filter designed to be replaced, not washed and reinstalled, for consistent filtration each season.
• Built for RV, campervan, and boat owners running a ducted Truma Aventa air conditioning system who want to keep cabin air clean during dusty campground stays, gravel-road travel, or long off-grid stints without sacrificing cooling performance.

"You pull off the return-air grille on your Truma Aventa ducted ceiling assembly and the foam element is gray, matted, and pulling apart at the edges, a sign your rooftop AC has been drawing air through a filter that is past its job. A worn-out filter lets dust and pet hair reach the evaporator coil, chokes airflow, and can leave your cabin cooling slower than it should on a hot afternoon at the campground. This is a replacement filter (40091-01073) sized specifically for the Truma Aventa Ducted Ceiling Assembly used in ducted rooftop AC installations on campers, caravans, and motorhomes. It is made from 30 PPI (pores per inch) open-cell polyurethane foam, dense enough to catch airborne dust and debris, open enough to keep return airflow moving freely to the blower and coil. The filter ships with a pressure-sensitive adhesive (PSA) backing, so there is no tool, no trimming, and no guesswork: peel the liner, press the foam into place inside the ceiling assembly's return-air opening, and it is seated. Because it is a single-use element rather than a washable pad, each replacement gives you a fresh, fully-rated filter instead of foam that has been compressed and re-seated season after
