Lievore, Altherr & Molina DCG adjustable core circular diffusers The DCG series diffusers are designed to be used in air-conditioning, ventilation and heating in premises from,6 meters high. They can be mounted in false ceilings, or ductwork or suspended from the ceiling. The diffusion of the air can be varied by adjusting the inner cones, changing from horizontal projection to vertical projection in accordance with the supply air temperatrure, providing good performance qualities for temperatures differentials up to 1ºC and reducing stratification. 1 0/1
CLASSIFICATION DCG Circular diffuser with adjustable core. DCG-ACTIF Adjustable cone diffuser that is autonomously thermally adjustable by means of a thermodynamic spring. Designed to be used in premises with varying heights in excess of 4 m. and a temperature differential of up to 1ºC. The diffusion of the air can be varied by adjusting the inner cones, changing from vertical projection to horizontal projection in accordance with the supply air temperature.

ACCESSORIES PLDG Plenum box with a lateral circular connection. It includes supports to hang from the ceiling. -R Plenum box with a flow damper in the spigot. /S/ Plenum box with an upper circular neck connector. /AIS/ Plenum box thermoacoustically insulated by a foam with a coefficient of thermal conductivity of 0,04 w/mk. This foam complies with the fire reaction specifications: UNE -77 M NFP 9-01 M DIN 4 M RG Flap damper assembled in the diffuser neck. Manually operated. Constructed in galvanised steel. RG Flap damper assembled in the diffuser neck. Screwdriver operated. Constructed in galvanised steel. RG 80 H 160 00 0 1 0 H 14 16 190 4 44 66 C 17 197 47 1 98 C 80 0/1
FIXING SYSTEMS (D) Connection into a circular metallic duct by means of rivets. (P) Connection into the PLDG plenum box by means of two central screws, to hang the assembly from the ceiling with drop rods. Unsuitable for DCG-ACTIF and dampers. To regulate the flow in plenum box mounting, we suggest the PLDG-R that incorporates a damper in the plenum spigot (available up to Diam. ) (P) Connection into the PMG crossbar by means of central screw. Suitable for mounting in false ceiling with rectangular duct. Constructed in galvanised steel. Unsuitable for DCG-ACTIF or RG damper. (O) Fixing with hidden screws. Suitable for mounting in false ceiling with flexible duct. Available for DCG up to 0 mm nominal diameter. Unsuitable for DCG-ACTIF. 4 0/1
