Dampers, VAV & Silencers

Dampers are vital components in HVAC systems, providing control and safety functions across various applications. Volume control dampers regulate airflow within ducts to balance and optimize air distribution. Motorized dampers, equipped with actuators, allow for automated adjustments, improving energy efficiency by responding to changing environmental needs. Non-return dampers prevent reverse airflow, maintaining system integrity, while pressure relief dampers release excess pressure, protecting ductwork and equipment. Fire dampers from Alpha Ducts ensure fire containment, while motorized fire and smoke dampers enhance safety by automatically sealing off areas during fire incidents, preventing the spread of flames and smoke. Together, these dampers create a robust, efficient, and safe HVAC environment.

Flowtech's pressure-independent VAV/CAV terminal units control supply air volume in variable volume systems. They feature a circular inlet spigot, rectangular outlet, and a cross-flow differential pressure sensor for accurate measurement. The damper blade has an EDPM gasket to minimize leakage, and control components are housed in an optional panel. Made from stainless steel, round outlets are available, with optional accessories like heaters and sound attenuators.

Bypass Terminal Units regulate primary air flow, using a diverting damper to redirect air into the plenum return. With a circular inlet spigot and rectangular outlet, they feature an EDPM gasket for low leakage. The damper is controlled by a room thermostat with a 0-10 volt signal to meet thermal demand.

• Pressure Independent VAV/CAV
• Bypass VAV

Sound attenuators, also known as silencers, are essential components designed to minimize noise levels in various industrial and commercial applications. These devices are commonly used in HVAC systems, ventilation setups, and exhaust systems to ensure a quieter and more comfortable environment. Flowtech's sound attenuators are engineered for optimal acoustic performance, reducing sound transmission while maintaining efficient airflow. By incorporating advanced materials and precise designs, these silencers effectively dampen noise generated by fans, air movement, or equipment vibrations. Ideal for industries prioritizing noise control and operational efficiency, these sound attenuators offer a reliable solution for creating quieter and more productive spaces.

Attenuators are constructed in accordance with DW144 H.V.C.A. duct work manual so that it is built to the same standard as the duct work and tested in accordance with ASTM E477.
