VAI®’s Environmental Control Monitoring Division (ECMD) addresses the needs of the pharmaceutical, biotechnology, semiconductor, and electronics industries with a complete range of compressed air/gas viable environmental monitoring equipment.
VAI offers both the automated SMA® Compressed Air/Gas Sampler, and the manual SMA Compressed Air/Gas Atrium for the collection of microorganisms in compressed air and gas lines.
The SMA Compressed Air/Gas Sampler is used for the automated collection of microorganisms in compressed air and gas lines. It monitors and regulates air flow, has a programmable timer, and can sample compressed air/gas lines up to 100 psi at 1 CFM. The instrument can sample compressed air, nitrogen, carbon dioxide, and argon. Contact VAI before sampling any other gases (e.g. oxygen). The SMA Compressed Air/Gas Sampler incorporates the same multi-orifice sampling methods as the standard SMA Atrium® that allows continuous monitoring of compressed air/gas lines. The instrument has a safety mechanism that releases pressure when incoming gas pressure exceeds 100 psi. Furthermore, it allows you to view air flow in CFM or Liters Per Minute (LPM).
SMA Compressed Air/Gas Atriums are used for the manual collection of microorganisms in compressed air/gas lines with either a rotameter or a pressure regulator valve to determine the level of viable contamination. A SMA Compressed Air/Gas Atrium is a 316 Stainless Steel capture device that is connected to a compressed air source. It has an extension tube that attaches to ¼ inch Hytrel® tubing. Air is directed from the compressed air source to impact onto a media plate contained inside of the Atrium. The plate is then incubated and tested to determine the level of any present viable contamination. Air flow calibration and timing must be performed manually using separate instruments. To regulate air flow, install a pressure regulator valve at the point of sample or use our SMA-ROT-SS-60C rotameter.
