PDS-21 Pressurized Cavity Drying for Behind Cabinets and Wall Voids

The VIKING PDS-21 is a pressurized wall cavity dryer that pushes heated, dry air through tubing into spaces a conventional air mover cannot reach. There is no squirrel cage and no external attachments. Restoration crews use it to dry under sinks, behind permanent cabinets, and inside wall cavities, which shortens the dry-out on kitchen and bathroom losses.

PDS-21 Heated Pressurized Drying System

The PDS-21 dries enclosed assemblies directly instead of blowing air across a surface.

  • Heated air up to 205°F through 200 ft of tubing — reaches wall cavities, under sinks, and behind permanent cabinets that air movers cannot dry
  • On-board Plug-Off system — raises pressure to push heated air deeper into closed assemblies
  • 92 CFM 2-stage tangential by-pass motor — drives the air without a squirrel cage or bolt-on attachments
  • Built-in cord wrap, 19 lb stackable housing — stores and stacks without loose cords hanging off the unit
  • Thermal protection switch with auto reset — guards the motor on long unattended drying runs
  • Runs on a standard 115V circuit at 9 amps — sets up on site without special power

PDS-21 Applications and Environments

The PDS-21 is built for water-damage restoration of kitchens, bathrooms, cabinetry, toe-kicks, and wall cavities after floods and pipe leaks. The roto-molded polyethylene housing holds up to job-site handling, the motor is UL approved, and the unit ships with tubing and a 25 ft cord. The one-year limited warranty covers the unit but not the brushes, which are a wear part on the PDS drying line. For cavity drying in occupied structures, it lets crews dry in place rather than opening walls.

Frequently Asked Questions

What is a wall cavity dryer used for?
The VIKING PDS-21 delivers heated, pressurized air through tubing into wall cavities, under sinks, and behind permanent cabinets and toe-kicks that conventional air movers cannot reach during water-damage restoration.
How hot does the PDS-21 get?
It delivers heated air up to 205°F at 92 CFM. The on-board Plug-Off system raises pressure to push that heated air deeper into closed assemblies.
How does the PDS-21 differ from an air mover?
It has no squirrel cage and no external attachments. A 2-stage tangential by-pass motor drives heated, pressurized air through 200 ft of tubing instead of blowing across a surface, so it dries enclosed cavities directly.
What power does the PDS-21 require?
It runs on a standard 115V/60Hz circuit and draws 9.0 amps. A thermal protection switch with auto-reset guards the motor on long unattended runs.
Is the PDS-21 warranty different from other XPOWER equipment?
Yes. The XPOWER/VIKING limited warranty covers the unit for one year but does not cover the brushes on the PDS line beyond first use, since the brushes and motor are wear-and-tear parts.
