UniFire PPV DS-3


The DS series positive pressure ventilation (PPV) fans feature high performance Honda motors, stainless steel frames, are tiltable from -10° to +20°, open-shroud design, and are stand alone operation.

Direct Drive

All Unifire positive pressure ventilation (PPV) blowers feature a direct drive design. By being direct drive we essentially gain 10% power transfer from the motor to the blade over belt driven models.

Shatter Proof Unitron Blade

100% shatterproof, high heat thermal plastic. Made of synthetic nylon, reinforced with carbon fibers. Impact and stress resistant with the best thermal expansion and contraction available.

Stand Alone Operation

Unifire positive pressure ventilation (PPV) fans and blowers are vibration free for standalone operation. They will not move on wet or slick surfaces. This is accomplished through balanced weight distribution and many other factures that help eliminate vibration.

Stainless Steel Wrap Around Frame

Lightweight yet strong stainless steel frame provides 360° roll protection. The low arc design evenly distributes weight to all four legs and feet for vibration free operation.

Patented Friction-Lock Tilt Lever

The friction-lock tilt lever allows for fast and easy adjustment to any angle from -10° to +20°. This enables the operator to pinpoint airflow and create the prefect seal.
