Alicat Scientific’s Whisper series of mass flow meters and
controllers saves time and money in semiconductor and
other process industries with systems using very low pressure differentials or exotic gases.
All Alicat meters and controllers are based on laminar flow
technology. The Whisper Series achieves a differential pressure
range of .01 to 2.0 PSID, depending on flow rate and
Whisper flow meters and controllers can oper-
ate as standalone devices or integrate into process
control instrumentation. In addition to mass flow, a
single device measures pressure, temperature, and
volumetric flow. For applications requiring precision
gas flow control, the device delivers flow regulation
of gases with the ability to respond to upstream gas
Gas Detector The gas detector from Sensor Electronics is designed to protect areas where toxic/explo- sive gases, including hydrogen chloride and ammonia hydrides, pose a constant hazard. The detector “sees” only one specific gas and cannot be confused by other gases that could cause false readings or alarms, or needless shut- downs. The stainless-steel construction repels corrosion, contamination, condensation, dust, dirt, aerosols, and temperature/humidity extremes. Factory- tuned for specific gases, the detector can turn on alarms to warn personnel. If gas concentrations increase, the detector can turn on fans to flood the area with outside air. www.sensorelectronics.com
Exair’s Super Air Amplifiers have no moving
parts, assuring maintenance-free operation.
No electricity is required, and flow, vacuum,
and velocity are easy to control. Outlet flows
can be increased by opening the air gap.
Supply air pressure can be regulated to
decrease outlet flow. Both the vacuum and
discharge ends of the air amplifier can be
ducted, making them suitable for drawing
fresh air from another location, or moving
smoke and fumes away. Cycle time is reduced
when aluminum casings are cooled with the
high-volume airflow of two air amplifiers.
The Super Air Amplifiers boost the amount of
airflow throughout the air amplifier. Additional
free air (room air) is pulled through the unit
while delivering a more balanced flow, which is
intended to make the Super Air Amplifiers run
quietly. Force and flow can be adjusted using
shims. Five sizes in aluminum are available.
