Oct 07, 2004 Available in 20 gf.cm and 40 gf.cm torque variations, RFRT-XXG-CLIP series aids in smooth opening of compartment or door. Snap-in design negates need for separate screws or ultrasonically welding this part. Push and snap-in motion holds damper firmly in place with its fixing wings. Using designated cut out in panel/chassis, damper is pushed into place through panel/chassis, exposing gear to integrate with toothed rack of compartment door.

Kinetic Systems, Inc.    Boston, MA 02131
Aug 24, 2004 Available in 4 sizes, Series 8001 Active Electronic Vibration Isolation Platform isolates instruments from 6 translational and rotational modes of vibration. Portable unit features microprocessor control, has natural frequency of less than 1 Hz, and incorporates automatic leveling mechanism. Using active feedback, it damps vibrations from 1.0–1,000 Hz. For vibrations above 1000 Hz, unit provides passive vibration control. Load capacities are 330–600 lb.

Continental Fan Mfg. Inc.    Buffalo, NY 14215
Nov 28, 2003 IRIS-S has interlocking AISI 316 stainless steel plates. Calibrated control lever allows blades to form adjustable aperture, permitting airflow regulation and measurement at one location. Damper measures differential pressure across pressure ports and refers to matching performance curve to determine airflow. Offered in 10 sizes from 4–32 in. with capacities to 20,000 cfm, it has neoprene gasket for airtight mounting.

Lloyd Industries Inc.    Montgomeryville, PA 18936
Sep 10, 2003 LloydStat(TM) works with smoke/fire damper equipment to prevent ductwork damage via controlled closing mechanism. It closes and locks damper upon smoke detection, fire conditions, or power failure via actuator closure spring. Unit operates using electric bi-metal disc sensor thermostat that interrupts power to actuator. Once activated, spring return closes and locks damper within 10-15 sec. Once unit cools below sensor set point, product returns damper to open position.

Continental Fan Mfg. Inc.    Buffalo, NY 14215
Sep 03, 2003 With IRIS-M motorized damper, minimum and maximum airflows are measured within ±5% by using product's pressure port and altered by means of actuator adjustment screws. Unit varies airflow in response to 0–10 Vdc or 4–20 mA signal to control temperature, humidity, or ventilation rate. External switch fully retracts damper for duct cleaning. Made from galvanized steel with neoprene seals, 6 sizes are offered to fit ducts from 4–12 in. dia.

AirLoc Products    Franklin, MA 02038
Jul 07, 2003 AirLoc Horizontal Wedgmount® Machine Supports offer integral damping and cushioning capabilities that dissipate up to 90% of horizontal load forces. Available with different mounting brackets, hardware, and vibration control pads, products can be adapted to customer requirements for machines and presses up to 3,000 tons or more. Installations include 4 individual supports offered in sizes that can withstand horizontal load forces from 5,000–250,000 lb.

Kinetic Systems, Inc.    Boston, MA 02131
Jun 17, 2003 Portable, tabletop Series 8000 uses active feedback to achieve high levels of vibration isolation for high-resolution instruments. It dynamically isolates all 6 possible translational and rotational modes of vibration with low natural frequency of 0.7 Hz. Microprocessor-controlled, automatic leveling mechanism rapidly adjusts to different loads up to 330 lb without user intervention. Isolation begins at 1.0 Hz and increases rapidly to 40 dB at 10 Hz.
