Lindab CBA Perforated Diffuser
Maelezo
Comdif CBA ni kisambazaji cha uhamishaji chenye matundu ya nusu duara kwa usakinishaji dhidi/kwenye ukuta au safu wima. Nyuma ya bamba la mbele lililotobolewa, CBA ina vipuli vinavyoweza kurekebishwa kibinafsi, na hivyo kufanya iwezekane kubadilisha jiometri ya eneo la karibu. Kisambazaji kinaweza kugeuka na kuwa na uunganisho wa duct ya mviringo (kipimo cha MF), hivyo diffuser inaweza kuunganishwa juu au chini. Kisambazaji kinafaa kwa usambazaji wa kiasi kikubwa cha hewa iliyopozwa kwa kiasi.
- The diffuser is suitable for the supply of large volumes of air.
- Jiometri ya eneo la karibu inaweza kubadilishwa kwa kutumia nozzles zinazoweza kubadilishwa.
- Duct covers, plinths and wall brackets can be supplied as accessories.
Matengenezo
Sahani ya mbele inaweza kuondolewa kutoka kwa diffuser, na kuifanya iwezekanavyo kusafisha nozzles. Sehemu zinazoonekana za kisambazaji zinaweza kufutwa na tangazoamp nguo.
