DS SERIES FEATURES

DS SERIES FEATURES

STAND-ALONE OPERATION

Unifire Positive Pressure Ventilation (PPV) Fans and Blowers are standalone operational. They will not move on wet or slick surfaces. This is accomplished through balanced weight distribution and many other factors that help eliminate vibration where the fan meets the ground.

OPEN SHROUD DESIGN

The open shroud design allows for 20% more air flow and better channeling of air. Faster sealing and greater thrust is produced through the air cone since the air is pulled from the back, sides and tips of the Unitron Blade.

SHATTER-PROOF UNITRON BLADE

100% shatterproof high-heat Unitron thermal composite. Impact and stress resistant with the best thermal expansion and contraction available.

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.

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.

HIGH PERFORMANCE HONDA MOTORS

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) fans and blowers feature a direct drive propellers. By being direct drive, 20% more power is transferred from the motor to the propeller over belt driven models.

PATENTED FRICTION-LOCK TILT LEVER

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