Industrial Dampers Dealers in Yamunanagar

Dampers are used to throttle the air entering or leaving a fan and to control airflow in branches of a system or at points of delivery. Dampers control airflow by changing the amount of restriction in an airstream. Increasing the restriction creates a larger pressure drop across the damper and dissipates some flow energy, while decreasing the restriction reduces he pressure differential and allows more airflow Single Blade Dampers This is the cheapest and simple type of damper normally fitted at fan inlet for manual control. This damper is suitable for situations where accurate volume flow is not required.   Multivane Dampers Control dampers are offered with either parallel or opposed blades. Each style has distinguishing characteristics in regards to control of the fan’s performance plus a change in air velocity profile. Parallel blade dampers have excellent control over the range of 75% to 100% wide open volume due to the amount of control arm swing required to modulate the blades. Parallel blades are used when greater control is required near the top end of the volume operating range or for systems requiring two position (fully open or fully closed) operation. Parallel blades should not be used upstream of critical components due to uneven airflow. Opposed blade dampers offer the best control over the entire operating range. Opposed blades are used for applications where it is necessary to maintain even distribution of air downstream from the damper. This style of blade is the best selection for ducted outlets.     Type of Dampers Backdraft Dampers Inlet Box Dampers Nested Inlet Vane Dampers External Inlet Vane Dampers
