EXTRACTION-CAP

The EX-CAP (EXTRACTION-CAP) is a self-sealing vapor-sampling cap that takes the place of a standard monitoring well cap, where vapor monitoring is required.  It operates as a watertight locking expansion plug with the capability of having vapor or water extracted through the cap, without removing the cap from the well.

The patented EX-CAP also has the ability to stabilize water tables in creating an ambient condition with both watertight enclosure and open atmosphere without, compromising the integrity of the well.

THE EX-CAP PROVIDES:

  * WATERTIGHT SECURITY

  * SAMPLING ACCURACY & QUALITY

  * REDUCED FIELD TIME

  * REDUCED PERSONNEL EXPOSURE & DECON

  * CONTINUOUS VENTING CAPABILITY

The EX-CAP is a permanent remediation tool for the sampling or testing of air & water.  The EX-CAP works with almost any situation involving negative or natural pressure such as vapor extraction systems, monitoring wells, methane gas, and radon detection.

The EX-CAP is made entirely of a reinforced chemical resistant nylon, and has two separate BUNA-N O-Rings for watertight integrity.  The top portion of the EX-CAP has a stainless steel, easy  to use flip down locking hasp that allows you to secure the cap with any #1 padlock.  The EX-CAP is currently sold in two sizes, 2" & 4" .  Smaller & larger sizes are available, through custom ordering.  " No Tools or Valves Required"

The EX-CAP was engineered for the roughest environment.  Its inert composition and self-sealing quality lends itself to being recognized as rugged, but user friendly.  The snap on feature of the EX-CAP is a brass self-sealing, quick disconnect couple with .28 vacuum (in./Hg.) virtual resistance.  It adapts quickly to most any vapor analyzer, magnehelic, vacuum gauge, or peristaltic pump.  The EX-CAP has a pull-away chemical resistant dust cover to protect the couplings outer face when not connected.

The EX-CAP for water has the ability to provide up to one GPM of fluid or a deep gas sample through its nylon compression fitting port on the bottom side, were an umbilical tube would be attached an set into the well at the desired depth.
