Cassette grille lowers for filter maintenance
Replacement grilles for Mitsubishi Electric ceiling cassettes can be automatically lowered on any ceiling up to 4 m high so that filters can be cleaned by someone standing on the floor. The PLP-6BAJ grilled can be fitted as a replacement for any PLA or standard-size PLFY models of 4-way-blow cassettes.
These grilles can be controlled from a PAR31 controller or the remote control that comes with the grille.
Keeping filters clean saves on energy use and reduces the smudges and stains on ceiling tiles caused when filters become dirty.
