Description
The PLZ pneumatic ventilation control unit includes a built-in ventilation valve that can be combined with a priority valve. The ventilation valve can be configured with additional accessories, allowing it to be controlled, for example, via a wind and rain control system. The desired operating pressure for ventilation can be set using the built-in filter regulator with operating pressure gauge, water separator, and condensate drain screw.
The housing is made of sheet steel and is optionally available in blue (RAL 5012).
The box is prepared for a 6 mm pipe connection as standard, but it is also available for an 8 mm pipe connection upon request.
