Workshops & Jobsites
Airflow Moves.
Outlets Don’t.
For workshops and jobsites, airflow is not always needed in the same place — and power is not always available nearby.
The usual problem
With DFF-101
01
No outlet nearby
The cord decides where the fan goes.
Slide in an 18V battery and put the fan where the crew is working.
02
Power cuts
When the grid drops, airflow stops.
Switch to battery and keep air moving, with no generator needed.
03
Short battery life
Cordless fans quit before the shift ends.
Over 24 hours at minimum speed on one 5.0Ah battery.

Key Features
Built For
More Flexibility.
01
Full-copper BLDC motor
3,450 m³/h
Moves air at up to 300 m/min while using less electricity than a conventional brushed motor, so it costs less to run on AC and lasts longer on a battery.
02
Stepless speed
0–1,200 RPM
An easy knob sets airflow anywhere in the range, with no fixed steps to choose between.
03
360° head
Air in any direction
The head turns through 360°, so airflow can be directed where it is needed for cooling, drying or ventilation.
04
Optional
Misting function
A misting option is available for extra cooling in hot conditions.

FAQ
Common Questions.
Can the DFF-101 run without a battery?
Yes. Plug in the adaptor and the fan runs on 90-250V AC power with no battery fitted. Slide in an 18V battery when you need to work away from an outlet.
How long does it run on a battery?
With a 5.0Ah battery: up to 3.5 hours at maximum speed and over 24 hours at minimum speed. With a 4.0Ah battery: up to 2.8 hours at maximum speed and 19.2 hours at minimum speed.
Which AC voltages does it accept?
90-250V, so the same model can be used on 110V and 220-240V grids.
How is the speed adjusted?
A knob gives stepless speed control from 0 to 1,200 RPM, so airflow can be set anywhere in the range instead of choosing between fixed steps.
What motor does it use?
A full-copper brushless DC motor, delivering 3,450 m3/h of air volume at an air speed of up to 300 m/min.
What is it used for?
Cooling, drying and ventilation in workshops, garages, warehouses and jobsites, including areas where power is not available nearby.
Is a misting function available?
A misting function is available as an option. Ask our team about availability for your market.
