Taper Draft Airflow Technology

Taper Draft Airflow Engineered for a Clean, Productive Work Environment

At the heart of Duroair’s modular clean air solutions is our patented Taper Draft Airflow Technology that goes above and beyond traditional cross drafts by creating indoor environments so clean they exceed OSHA requirements.

For an innovative clean air solution, taper draft airflow works with:


How Taper Draft Airflow Technology Works

When paired with DuroRoom™ and Duroair’s air filtration technology, our Taper Draft Airflow Technology pulls enormous volumes of clean air through an intake filter. Once the air is inside the enclosure, it continues to flow into the filter to create a clean air chamber that is impervious to contamination.

Features & Benefits

  • Prevents contamination from corrosive dust and hazardous fumes that can threaten employee safety and reduce the lifespan of valuable machinery
  • Speeds up drying times for water-based paints and coatings without the use of additional quick-dry agents
  • Contains overspray by pulling the particles directly into the tapered filtration chamber, so the particles don’t settle on the workpiece, shop floor, paint booth, or anywhere that can impair quality control
  • Reduces operating costs via energy savings compared to inefficient cross drafts used in traditional air purification systems
  • Improves productivity by reducing downtime previously spent cleaning dusty floors and dirty, clogged machinery

Technical Specifications

  • Tapered airflow focuses the air down the center of the enclosure and over the work piece with almost no airflow down the walls, ceiling or floor
  • Allows for the optimal capture of overspray and reduces any dust or dirt transfer
  • Creates a wicking process that decreases dry times
  • Exhaust system creates a negative pressure vacuum seal, creating a clean purified environment
  • Ideal for a retractable clean room and/or containing airborne particulates and chemicals
