Air flow controllers

The product range of SLT comprises constant flow rate controllers (for flow rates of 15 m³/h to 23000 m³/h) as well as variable flow rate controllers (for air flows of 32 m³/h to 39000 m³/h). Constant flow rate controllers generally operate without external energy and are factory/site set. Variable controllers incorporate a measuring device and a damper actuator/controller, which modulates the air flow as dictated by an input control signal. Different models (air-tight) and accessories (insulated casings) are available.
