The Dry Air Technology Max Force is an ultra-high CFM, high-pressure ventilator air mover that is ductable and versatile. It is a single-speed axial machine built to push a large volume of air through ducting or across open space, with duct rings on both sides so it can be ducted on the intake, the discharge, or both.
This is the 220 V / 50 Hz version with an Australian plug (Dry Air part AF-01T-E1B20337).
What It Is For
Most air movers are built to blow across a floor. The Max Force is built to move air where you cannot put a floor air mover: through a duct into a crawlspace or roof void, up to a high ceiling, or out of a building to create negative or positive pressure. Its industrial motor and duct rings are what make it effective for drying out ducts and cavities over long distances.
Features and Benefits
- Rout out hard-to-reach cavities like crawlspaces and attics with this ductable air mover
- Take on jobs with tall ceilings without having to bring and construct scaffolding
- Ventilate structures by creating negative or positive air pressure
- Weighs only 17.69 kg (39 pounds) for fast, easy transporting
- One horsepower motor (amps: 4.3) runs continuously on long drying jobs
- Moves 390% more air over turbo air movers (Dry Air Technology's comparison)
- Adaptable to older models with kit that increases air power by 10% (as listed; ask us which kit and which models this refers to)
The Max Force Is Suited To
- Moving large volumes of air through ducting for hard-to-reach areas
- Ventilating crawlspaces and attics
- Using on a stand as the centre unit in a Vortex Drying System
- Using as a high-volume unit for open air drying
- Directing air to hard-to-reach areas for spot drying
- Using with attachments for negative and positive pressure drying

Two figures are shown as published rather than averaged. The listing's opening describes a 4-amp motor while the feature list gives 4.3 A; 4.3 A is used above. Dry Air Technology lists the US 115 V model at 8.6 A and 38 lb (about 17.2 kg); those figures apply to the US model, not this one.
Ducting It Properly
- Keep runs as short and straight as the job allows. Every metre of duct and every bend costs airflow. The 15 m ductable figure is a maximum, not a target.
- Secure the duct to the ring. A duct that pulls off overnight in a roof void does no drying and nobody sees it happen.
- Decide which side the duct goes on. On the discharge side the Max Force pushes air into the space. On the intake side it draws air out, which is how you pull a cavity or a room into negative pressure.
- Negative pressure is not containment on its own. Where the job is mould, sewage or other contamination, exhaust through a HEPA air scrubber and set up proper containment rather than blowing contaminated air elsewhere in the building.
Electrical Safety
- Plug into an earthed outlet protected by an RCD. The machine is used on wet sites.
- Inspect the lead and plug before every use, and keep the machine within its test and tag schedule.
- At 4.3 A per machine, count how many units share a circuit before you start a multi-machine job. A tripped breaker overnight means a lost night of drying.
- Unplug before removing either grill or clearing the fan.
Care and Maintenance
- Check both grills for fibre, dust and insulation between jobs. A blocked grill starves the motor of cooling air.
- Clean the fan blade if the machine starts to vibrate. Build-up on one side of an axial blade throws it out of balance and wears the motor bearings.
- Transport it so the grills are protected. A grill bent against the blade causes scraping and blade damage.
Warranty
Dry Air Technology lists 1 year on parts and labour and 10 years on the cabinet, chassis and housing for the Max Force (filters and accessories excluded). Confirm the terms that apply to Australian purchases with CCW before you buy.
Frequently Asked Questions
Is the Max Force a normal floor air mover?
No. It is a high-volume ductable ventilator. For drying carpet and floors at floor level a standard air mover such as the Dri-Eaz Velo is the usual tool. The Max Force is for ducting air into cavities, reaching high ceilings, and pressurising or depressurising a space.
How many speeds does it have?
One. Dry Air Technology lists it as single speed.
How far can I duct it?
Dry Air Technology rates it as ductable to 50 ft (about 15 m). Airflow falls with length and bends, so use the shortest run that reaches the area.
Which ducting do I need?
The duct ring diameter is not published. Tell us the job and we will confirm the ducting to suit before you order.
Can I use it for negative air on a mould job?
It can create negative pressure, but it has no HEPA filtration. On contaminated work, exhaust through an air scrubber with appropriate containment.
Is a stand included?
A stand is not listed as included. Ask us if you want to run it as the centre unit in a Vortex Drying System.
