RPM-LV
Variable air flow controller for low air velocities with high precision
RPM-LV - The airflow regulator is designed to control variable airflow in a circular duct. If variable air flow is used as needed, the operation of the air handling equipment is more economical. This compact device regulates from very low air velocities, based on a unique technical solution protected by utility model “Patent”.
Properties
•to control variable or constant airflow in ventilation systems
•diameters from 80 to 315 mm
•flow rate from 9 to 2 244 m3/h (for example from 2.5 to 623 l/s)
•for air velocities from 0.5 m/s
•working since the control pressure loss is above 2 Pa
•compact construction - no sharp and obsolete devices inside the damper
•made of galvanized steel sheet
•each controller is equipped with pressure sensor next to the blade and customized actuator (Belimo LMV-D3W-MP.1 MDK, supply voltage 24 V, control voltage 0-10V or 2-10V)
Specifications
Air flow controllers are intended for the use in buildings, installed in air supply or air exhaust ducts of HVAC systems. Controlling the air flow in different branches of the system, the air is directed to where needed when needed in order to assure both well-being and economic operation. The controllers with variable air flow rate consist of the air-tight body, air-tight damper blade firmly mounted on a shaft, electric actuator, air flow rate measuring system, and of the electronic controller including communication interface. RPM-LV air flow controllers represent the latest generation of devices based on differential pressure air flow measurement principle, benefiting from intensive local variations of the pressure field around the damper blade. MANDÍK design profit from many years of experience with production of accurate, robust and reliable air flow controllers combined with innovation drive and state-of-the-art laboratory testing. In addition to precisely controlled production process, high-end components from top suppliers contribute to performance fully exploiting the potential of the basic principle of function, benefiting also from the input from our customers, designers of HVAC systems, installers and end users.
