Productspecifications

Lay-in design allows quick/easy installation on site in most T-bar suspended ceiling systems.
Removable face-plate to simplify maintenance and access to air pattern adjustment blades and volume control without opening the ceiling.
High induction ratio and horizontal discharge pattern, suitable for CAV/VAV applications.
The integral cylindrical air pattern stabilizer assures a uniform air distribution across the diffuser face independent to the inlet spigot position even with irregular duct approach. It also results in less pressure drop through the plenum box.
Integral hinged baffles to (re)adjust the air pattern (1-way, 2-way, 3-way or 4-way).
Deflection disc to maintain a horizontal air pattern at different volumes.

Application

Types PBD..04 ceiling diffusers with removable perforated face-plate are designed for (easy) installation in suspended T-bar type ceiling applications. Their horizontal discharge pattern and high induction ratio result in rapid temperature and velocity equalization and ensure confident use in cooling and/or heating in CAV or VAV applications with temperature differences up to 11°C and a relatively high amount of air changes per hour, even in rooms with low ceilings. With the integral air pattern adjustment blades a 4, 3, 2, or 1-way air pattern can be easily (re)adjusted to suit the room requirements.
