However, in heating mode, the diffuser must have high penetration depth, in order to achieve fast and efficient heating. The ceiling diffuser type IDA meets both these requirements ideally. It ensures optimum air distribution in cooling and heating modes. The diffuser consists of an adjustable air guide funnel and a...
