...Ruskin always pays off.Built using Ruskin's [model:iaq50]IAQ50[/model] air flow measuring and control dampers, the new air curtain successfully provides consistent airflow. The system includes two 65,000 cfm centrifugal fans installed in the space below the return air walkway grate. The air returns through the grate into the basement plenum and passes through two 144 square foot filter and coil banks. It is then ducted up from the fans into the plenum space above the air curtain supply opening. The air then passes through the IAQ50 air flow measuring/control dampers and is direct-ed through an adjustable deflection type grille.
The individual IAQ50 dampers measure and control the airflow between the existing structural supports. This helps guarantee the air curtain maintains the required velocity and prevents conditioned air from escaping through the opening.
"Opening up the Four Queens to the Fremont Street Experience has been a tremendous success" says Max Proctor, Four Queens Building manager. "We ...

Outside air entering a building should be properly measured and controlled in order to meet the requirements of ASHRAE 62. This type of measure and control can be done in a variety of ways.

Measuring and Controlling Outside AirThe most common system uses a minimum outside damper air measuring station combination that controls the outside air coming into the building when the main outside damper closes. Air measuring stations have a minimum limit around 400 fpm, which is sensing approximately .01" of velocity pressure. The control at this point is 5% of the cfm being measured or 750 cfm out of 15,000 cfm. With the minimum outside control, you only measure and control the air when the main outside air damper is closed.
There is also a system that uses multiple damper air measuring stations to control the total amount of outside air introduced into the building. These systems close off dampers as the demand for outside air decreases and keeps the control signal pressure high enough to maintain good accuracy.
Another system design uses a fan damper and air measuring system to force the minimum amount of outside air into the air mixing chamber. This type of system works well, however, it requir ...

Ruskin is proud to announce the latest addition to its line of air monitoring dampers. The CDRAMS model is a true round air monitoring, low leak control damper that is easily installed in round spiral ductwork."The industry has been demanding a round air measuring damper with low leakage," said Michael Wiltfong, head of Ruskin's Control Dampers group. "And Ruskin met the challenge."The CDRAMS joins the [model:iaq50]IAQ50[/model] and [model:ams50]AMS50[/model] as Ruskin's latest air measuring damper. These dampers enable buildings to better meet ASHRAE Standard 62, which defines the requirements for indoor air quality. The CDRAMS also features:[list][*]Specially designed blade-to-frame polyethylene foam seals that fully encompass the edge of the damper.[*]Extruded aluminum airfoil sensing tubes that sample the air pressure across the full diameter of the duct.[*]Ease of operation with optional manual, pneumatic, or electric actuators.[/list]Ruskin's CDRAMS provides the solution to providing indoor air quality ...

Ruskin Manufacturing, Kansas City, MO, announces an exciting new damper designed to meet the increasing engineering demands for indoor air quality. The IAQ50 is an innovative synthesis of three different functions: a high performance airfoil control damper, an airflow monitoring station, and a programmable controller, with the airflow station built into the damper frame.
The new IAQ50 assures that a building's ventilation system performs to the ASHRAE 62 standard, and it even provides documentary evidence to facility managers. Because of its compact size and unique versatility, the IAQ50 allows for installation into standard air handling unit construction, old or new, without any special system construction requirements, and also universally integrates with building automation systems.
Ruskin Manufacturing builds a complete line of commercial and industrial control dampers, fire/smoke dampers, louvers and grilles for the HVAC and architectural market.
Ruskin Manufacturing, Kansas City, MO, announces another industry first in Indoor Air Quality dampers, the Ruskin [model:13553]AMS50[/model] air measuring station. This new assembly is engineered and manufactured to give customers the ability to provide their own control package to coordinate with their building automation system and set CFM requirements in the field. The AMS50 has been tested and certified to meet AMCA Standard 611-95 for Airflow Measurement Performance. It combines control damper and flow measurement stations in one assembly and the standard construction includes an air strengthener section for reduced duct length requirements. In addition, the controller and actuator can be field or factory supplied.
