1.CIRCULAR AIR VAVES
2.DIFFUSERS
3.GRILS
APPLICATION RTBM (air supply)
The ceiling, rotational RTBM diffusers are used for supplying cold or warm air in the systems where the temperature difference between the room and air outside is large. They may be used in installations of constant and variable output. The air supply mode is fixed. The intake diffuser is designed for installation in modular suspended ceiling with 600 mm panels.
On request, it may be installed along with a plenum box. The rotational effect allows for achieving a significant air change rate. Due to a horizontal stream of supplied air, the RTBM diffusers are suitable for relatively low rooms.
APPLICATION RRBM (exhaust)
The ceiling, rotational RRBM diffusers are used for air exhaust. Its appearance is identical as that of the RTBM intake diffuser. The intake diffuser is designed for installation in modular suspended ceiling with 600 mm panels. On request, it may be installed along with a plenum box.
