OPTIMA-S-LPC is a variable low-pressure controller that can be supplied with or without insulation. The controller is designed to be installed into rectangular ducts via a duct connection with a flange. It has a wide range of possible applications, including offices, laboratories, industrial plants, healthcare premises, and public spaces. The product consists of a casing, a duct connection with a flange, multiple damper blades with a rubber gasket, and a modular pressure control device. It has high measurement/control accuracy with a deviation of 5%. It has a pressure control range of up to  ±75 Pa.

The OPTIMA-S-LPC features a static sensor that is capable of measurement even in a dust-polluted atmosphere. An insulated version, OPTIMA-S-LPC_BM is available for sound reduction. The insulation is a 19 mm thick closed-cell foam mat protected by galvanised steel sheet. The modular pressure control device consists of polyurethane measurement tubes for connection to the pressure impulse tapping spots, an air pressure transmitter, a modular control unit, and an actuator.
