Ruskin® recently announced the BTD830 bubble tight isolation damper, the company’s newest addition to its bubble tight product series. The BTD830 is a rectangular bubble tight damper ideal for applications where extremely low leakage is required, such as in food processing. The rectangular design offers more free area, lower pressure drops, and better airflow compared to round or oval dampers, and is a lower-cost alternative to other bubble tight dampers.
The BTD830 is bubble-tight according to the AMCA 500-D standard with a maximum velocity of 4,000 feet per minute, a static pressure of 10.0 inch water gauge (w.g.) (2.5 kilopascals [kPa]), and a temperature range of -40 °F to 250 °F (-40 °C to 121 °C).
