Clean Air Staff complete their 5 day training course on Aeroseal Duct Sealing
Ben Tricase, Technical Manager for Aeroseal LLC (USA) conducted the course at Clean Air’s office and workshop in Acacia Ridge, Brisbane. It covered both theoretical and practical training with Clean Air staff able to seal a demonstration rig of duct and fittings of various types. This put to the test the various claims Aeroseal LLC had made about the abilities of their product. The Clean Air team devised various hurdles for the Aeroseal Process to prove its effectiveness.
Test and Results:
1. A 15mm hole in a dead leg of duct
Completely sealed with a solid plug formed in the hole.
2. A perplex window in an access panel
There was no build on the persplex which remained visually clear even after 3 practice sealing sessions.
3. An unsealed access panel
A complete gasket was formed around the circumference of the panel frame. The Access Panel was still easily removable from the frame.
4. A myriad of holes via perforated sisal
All holes sealed completely
5. A jagged tear on a radius bend
Sealed completely in matter of minutes
6. Several holes in small looped flexible duct
All holes sealed completely with no build-up of sealant internally. Resisted further tearing of the liner.
7. P3 Ductboard - painted internally
All holes sealed from the inside with no build-up of sealant internally.
8. Perforated metal blocking 70% of the duct
No build-up of sealant on or in the perforated holes. Sealant flowed around to seal leaks further down the duct. This is a similar situation to Attenuators or Dampers.
Even the most sceptical of the participants conceded that the Aeroseal process had delivered on all its promises to “Seal from the inside”.
