Product Overview

The CVE Shop Return Air Grille & Filter is the one product which offers complete and simple service ability for all situations.

A unique design which can easily be installed. Ideally suited to environments where regular maintenance of the filtration media is a concern, the Return Air Grille & Filter is designed for quick, simple filter changes.

The actual filter pad is a product of exhaustive research by one of the world’s largest air filtration authorities with approval from the American Underwriters Laboratories. A distinct Black coloured filter media shows dirt and particle build-up and provides for ready inspection prior to replacement as required.

Replacement filters are usually available from stock - Part No. CVRAG/F
