Product Introduction

The 591 x 591 x 370 mm casing fits within a nominal 600 mm T-grid bay and supports a 597 x 597 mm diffuser. Its 300 mm top spigot and 0.14-0.27 m³/s flow range serve larger room zones than the mini housing while preserving standard suspended-ceiling coordination. Clean pressure drop remains 125-250 Pa.

Key Features

T-grid coordination

Larger branch connection

A 300 mm inlet supports the higher airflow range of this intermediate terminal.

Finished room face

Solutions for Your Application

A nonstandard casing complicates T-grid installation.Use the 591 mm housing and 597 mm diffuser designed around a nominal 600 mm module.

A small inlet cannot supply the required room volume.Use the 300 mm top spigot for the 0.14-0.27 m³/s duty.

Available Options

Confirm HEPA grade, diffuser, casing finish, branch connection and ceiling seal. Coordinate access for filter integrity testing and service.
