Choosing industrial ductwork shouldn’t come down to the price per foot of straight pipe. While spiral pipe may offer a lower initial material cost, US Duct and US Tubing are designed as complete systems that provide advantages in installation speed, durability, adjustability, sealing, and long-term value. This article compares spiral pipe with US Duct and US Tubing, highlighting key differences in construction, connections, leakage performance, field installation, and lifecycle costs. US Duct offers a strong, modular, adjustable solution for dust collection, most fume applications, and industrial air movement, while US Tubing provides a guaranteed leak-free connection for applications where air or fluid cannot escape. With clamp-together installation that can reduce installation time by approximately 70%, plus components that can be disassembled, modified, and reused, US Duct and US Tubing can deliver value well beyond the initial material price. The right choice ultimately depends on the system’s specific requirements for strength, sealing, installation speed, adjustability, and long-term flexibility.
Legend Inline Separator
- For shops that empty their bags more than once a day.
- Collects up to 90% of bulky material BEFORE the collector and deposits it into self-dumping hoppers.
- Keeps the shop running: customers report increases of 20% in operation time from keeping the collectors running.
- Perfect for shops with high-volume waste-producing machines currently collecting into plastic bags.
- Route over outside dumpsters.
How it works
The separator’s design incorporates two basic principles:
- Dust in general, and heavier dust in particular, will fall out of the airstream at low velocities. The larger chamber of the separator causes the air to slow down.
- Dust in general and heavier dust in particular will follow the initial path as it ‘blows’ by the outlet/exhaust duct, which sits directly behind the incoming and deflecting cone. This cone throws the material to the outside of the larger chamber AND ‘past’ the outlet/exhaust duct (see video below).
Separation varies with material and material mix. It works best on heavier material with limited ability to address fine dust.
