Fabricated in steel or aluminum, with low leakage options available. Backdraft dampers control the direction of airflown in HVAC applications. They freely allow airflow in the intended direction, but will close and prevent airflow in the opposing direction. Louvers are intended to protect openings in the external envelope of a building from the penetration of water where HVAC duct penetrations are made for the exhaust and intake of air.

NCA offers Louvers in extruded aluminum and fabricated steel or stainless steel. Metal Industries Celebrates 70th Anniversary. Through engineering and testing, NCA will continue to be a major player in the louver and damper market so engineers and designers can specify NCA with confidence.

My application is for a kitchen exhaust to end cold drafts and damper banging in the wind. That way gravity helps close the damper blades.

The springs are sized for typical flow in ducts. Only vertical orientation that will work is airflow up. The blower installed is a CFM. These can be used for bath or kitchen exhaust systems. We need a very small ventilation source for a cold storage unit that will be operating on DC, and want to have the intake closed when the fan is not operating.

Consider a motorized damper with the same voltage as the fan or from main power source for the fanso powering the fan will power the damper open. In general, any backdraft damper with a center pivot is not recommended as they tend to collect lint there. Asked on by Mike. Learn about solutions Makeup Air Fans - Residential.

Find blade type, velocity, pressure, AMCA listings, submittals, drawings and more, all in one easy-to-use format. Control dampers regulate the flow of air in an HVAC system for intake, exhaust, or mixed air applications. Industrial dampers use a heavy-duty flanged frame damper with multiple blade styles and pressure classes. These work in industrial and severe duty applications. These provide accurate monitoring and control of outside air. Backdraft dampers allow airflow in one direction and prevent reverse airflow.

These function as exhaust or intake dampers. Relief dampers allow excess airflow to lower indoor air pressure using counterbalance weights. Bubble-tight isolation dampers work in applications requiring very low leakage or zero leakage.

Kitchen Ventilation Systems.What is Pressure Drop? The air performance of a damper is described by the pressure drop across the damper. So what is pressure drop?

Pressure drop can be defined as the resistance to airflow across an open damper and increases as turbulent flow increases. Actual pressure drop is dependent upon many factors. This pressure drop information along with an analysis of system influences should be used to estimate actual pressure losses for a damper in a given HVAC system.

For AMCA certified pressure drop ratings on Air Performance see the appropriate damper model specification sheet for that model.

Important Notes:. See appropriate damper model specification sheet for minimum and maximum assembly and section sizes. Pressure drop and free area may vary. All calculations are with external mounted actuators and accessories. Turbulence may produce objectionable noise in some conditions with velocities above FPM.
