Horizontal Airflow

The Horizontal Airflow function prevents both cold draughts and/or heating airflow from striking occupants directly, thereby keeping people from becoming over-chilled/over-heated.

Wave Airflow Mode for Heating

Advanced control of vanes, called Wave Airflow, provides even greater heat distribution by periodically moving vanes up and down to provide a consistent temperature throughout the room.

Wide Airflow

PLA Series Cassettes utilise wide-angle outlets to distribute airflow to all corners of the room, ensuring the room is cooled/heated in an even manner. Both horizontal airflow and fan speed have been reduced by 20% compared to conventional models, contributing to increased comfort for occupants.

Optional Automatic Grille Lowering Function

An Automatic Grille Lowering function capable of stopping at eight different heights is available to simplify filter maintenance.
  • The packaged elevating (up/down) controller in the grille* can be used when outdoor unit is either PUZ Series or SUZ Series.
  • Wired Remote Controller (PAR) has Automatic Grille Lowering function. This function is only available when indoor unit connects with PUZ Series.

* PLA-M Series uses grille PLP-6EAJ and PLA-RP Series uses grille PLP-6BAJ.

Sleek, Compact Design

The PLA features a sleek, square design with bevelled edges that provide a compact and modern finish.

Auto Fan Speed Mode

The fan speed on Deluxe PLA Series Cassettes is adjusted automatically, maintaining a comfortable environment at all times. At the start of operation, a high fan speed achieves quick heating/cooling of the room. Once the desired temperature is reached, the fan speed is reduced for stable, more efficient heating/cooling and greater comfort.

Independent Vane Direction Setting*

With the ability to independently control each vane’s airflow pattern, Deluxe PLA Series Cassettes are perfect for both residential and office/commercial environments.
