Floor Gland

AIR-LOKK from Cannon TechnologiesThe floor gland/grommet offering signifucant performance enhancements. A  unique concept which corrects inadequacies of old fashioned floor grommets.

  • Retro-fittable
  • Surface mount
  • Drop in "All in One" Floor Gland
  • Power/Data Partition (optional extra)
  • Removable Brush

Two issues are of significant importance:

  • Cold air pressure should not lift the brush strip seal and escape
  • Hot air should not be sucked downwards into the cold air flow


Features and Benefits

  • The brush is Quick-Fit, Quick-Release removable allowing access through the gland, to under floor
  • The brush is mounted on a central bar  so that the tips of the brush rest on the sides of the gland where the brush is not heavily distorted by cables
  • (Cables do not pass through the root of the brush where bad distortion will occur)
  • This patented orienntation of the brush dramatically improves air blockage and supports the brush droop over time
  • Bend radii and cable tie points avoid corrupted data and simplify installation
  • One gland can be either "surface mounted", "drop in" (into the cut out in the tile) or retro-fitted around pre-installed cables reducing the range of glands required

Unique Brush Gland

The brush gland is pre-stressed to resist air pressure. The patented system provides firrm support to both ends of the brush and the brush tips press down, onto the radiused sides of the grommet, acting like leaf springs. This imparts greater resistance to air pressure.

  • IPACK 2001-15728ASME advises that grommet/tiles near the CRAC unit often experience negative air flow from inside the rack, pulling hot air down into the cold air stream.
  • AIR-LOKK grommets have been laboratory tested and brushes did not lift or flap until an air pressure of 1500 pascals (0.44" water gauge) was reached. Underfloor static pressure is commonly 6 pascals (0.025" water gauge). AIR-LOKK grommets substantially exceed the common static pressure with a high safety factor.
