This air flow device maintains Constant or Variable volume airflow by accurately reading the external conditions to deliver actual airflow required to condition critical areas. Very commonly used in laboratories, research facilities with high air changes and balanced pressurization. The device requires I/O signal as well algorithmic data transfer protocols from building management system as well loops to provide required feedback. This device can work in both Constant and variable volume mode.
Generally used in laboratories, research centers, bio safety cabinets etc where maintenance of pressure, temperature, and air flow is optimum to keeping the room/unit well calibrated. These devices are sensitive and can react in fraction of second to external signal that is being applied to react to an operation. Venturi Valves have become an important part of any lab design and with greater sophistication, these are expected to operate and communicate with Building control management system. Available in many sizes (6, 8, 10, 12 inches) as well additional fittings like re-heat transition, silencer can also be provided. Currently we are offering only low to mid range pressure systems.

PROBLEMS OF AIR STRATIFICATION In HVAC Air Handling system, air stratification resulted from the improper design inherent in moving air streams by keeping air streams of different air temperatures from mixing effectively for a long distance. A [...]
Iris damper is essentially a modulating damper that precisely controls the input/output of air by mere adjustment of simple mechanism. Like aperture of a camera that controls the flow of light, Iris dampers adjusts the air flow by precise adjustment of its bla [...]
These are series of damper assigned in a bank arrangement both horizontally/vertically to cover a required opening area. The main advantage of damper bank is control as well shut off flow of a larger area. Damper bank can also be synchronized to modulate flow [...]
