DST Series Positive Pressure Ventilation Fans

DST SERIES

POSITIVE PRESSURE VENTILATION (PPV) FANS

The DST series positive pressure ventilation (PPV) fans feature large flatproof pneumatic style wheels and tires, 35" extendable handle, high performance Honda motors, stainless steel frames, tiltable from -10° to +20° and are stand alone operational.  The DST series  are the most powerful compact positive pressure ventilator (PPV) fans and blowers available. Most models fit standard compartments and are lightweight for easy handling

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 features that help eliminate vibration.
Open Shroud Design
The open shroud design allows for 20% more air flow and allows for better channeling of air. There is also faster sealing and greater thrust through the air cone because the air is pulled from the back, sides and tips of the unitron blade.
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.
35" Extendable Handle
The ergonomically designed handle quickly extends to 35" and can be operated with one hand, making transportation easier. Available in DST and DU-ALL frames only.
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.
High Performance Honda Motors
All All the features you expect from Honda; electronic ignition, oil alert system, dual element air filtration system, and electronic ignition for easy starting..
Direct Drive
All Unifire positive pressure ventilation (PPV) blowers feature a direct drive design. By being direct drive we essentially gain 20% power transfer from the motor to the blade over belt driven models.
Stainless Steel Wrap Around Frame
Lightweight yet strong stainless steel frame provides 360° roll protection. The low arc design evenly distributs weight to all four legs and feet for vibration free operation.
Rubber Feet
Rubber feet aid the elimination of movement due to vibration.
**Four rubber feet on DS frames and two on DST and DU-ALL frames.
Wheels and Brakes
8" off road solid wheels with step-n-go quick lock brakes. Rubber feet also aid the elimination of movement due to vibration.
**Available in DST and DU-ALL frames only.
