/16 | RDR Description RDR is a constant air volume flow controller with mechanical type of operation (no need for auxiliary energy or actuation). It is intended to control the constant air flow independently of the duct air pressure in the range of 50 Pa to 250 Pa. The constant air flow value can be set by a shifting dial within a range dependent on the size and configuration of the product. The cartridge type casing fits into the circular ducts of 80 mm up to 250 mm in diameter.
