The DERBLAUE® Foldable Funnel has been specially developed for the professional cleaning and maintenance of split-system air conditioning units. It creates a large catchment area around the work area and reliably protects walls, floors and furnishings from dirt and rinse water.
Using the supplied one-handed suspension system, the Foldable Funnel can be attached directly beneath the indoor unit. This ensures it remains securely in place, leaving both hands free for the actual work. Smaller parts and components can be placed directly into the funnel during maintenance and remain within easy reach.
Robust fibreglass rods integrated all round ensure the necessary structural rigidity. Water produced during cleaning is safely collected and can be drained in a controlled manner via the 3/4-inch brass connection using a hose.
Thanks to the integrated folding hinge, the folding funnel can be compactly folded away after use and transported and stored to save space. This makes it particularly suitable for air-conditioning and refrigeration engineers who regularly work on site at customers’ premises.
