Air Products and Controls - FAST Tube is the latest innovation in air testing. These lightweight sectional sampling tubes are designed to fit all APC Duct Detectors. The composite material is rated the same as the detector housings, while a red fitting strip securely holds multiple sections together with no fear of tubes vibrating apart over time. One bag of tubes will fit duct widths up to 8 feet. Save any spare sections to use on the next job, or pair two packs for wider ducts.
Putting them together is as simple as APC: Assemble to length, Prep by affixing the starter from the detector hardware kit, then Cut and Cap to final length.
