air flow regulator
o Designed for air flow regulation in ventilation and air-conditioning installations. PJR ensure uniform air distribution after the unit and that differs it from single dampers.
o For bigger sizes double grilles with single control can be produced (PJR-D).
o Double multiple leaf dampers (PJR-BS) with single control are suitable for regulation of two air lows at the same time (inversely) or by-pass of recuperative heat exchanger air-air.
o Working temperature range from -20°C to +80°C.
