The Razorback MaxxAir AVP HP12 is a high-volume axial ventilator used for confined-space ventilation, positive and negative air set-ups, spot cooling, and exhausting fumes and dust. It suits restoration technicians, flood work and commercial jobs where you need to move a large volume of air or duct it into hard-to-reach spaces.
Compared to heavier metal fans, the AVP HP12 is lightweight and portable, which makes it easier to carry between jobs. Its heavy-duty polyethylene housing is described by the manufacturer as virtually indestructible and stands up to the knocks of daily site work.
Key features
- Large duct rings for a more secure duct fit
- True 300 mm (12 inch) fan blade
- Capacity to connect up to 50 metres of 300 mm duct
- Interlocking ribs for stacking vertically
- Durable, lightweight polyethylene housing
- Totally enclosed, energy-efficient, high-performing motor
- Designed for easy maintenance
Ducted ventilation and air movement
With the capacity to run up to 50 metres of 12 inch duct, the AVP HP12 lets you push clean air into, or pull stale air out of, confined and hard-to-dry areas. The large duct rings give a secure fit on both the intake and outlet sides, so you can set up positive or negative pressure and keep air moving where you need it.
Built for the job site
The totally enclosed motor and rugged polyethylene housing are built to handle restoration and industrial sites. Interlocking ribs let you stack units vertically for transport and storage, and the design keeps routine maintenance simple.
Using it well
- Keep duct runs as short and straight as the job allows. Every metre and every bend costs airflow; 50 metres is the maximum, not the target.
- Know which side you are on. Pushing air in pressurises the space; pulling air out puts it under negative pressure. Decide which you want before you set up.
- Negative air is not containment on its own. On a mould or contaminated job, exhausting air without filtration moves the problem outside or into another room. Use a HEPA air scrubber where the scope calls for filtered negative air.
- Confined spaces need a plan. Ventilation supports confined-space work; it does not replace the permit, atmosphere testing and standby that the work requires.

Frequently asked questions
What size duct does it take?
300 mm (12 inch) duct, up to 50 metres.
Can I use it for negative air on a mould job?
It can create negative pressure, but it does not filter the air. Pair it with, or use instead, a HEPA air scrubber where the scope requires filtered exhaust.
What is the airflow in CFM?
Not published for this unit. Ask us if you need it for a ventilation plan.
Can it be used as a floor drying fan?
It will move air across a floor, but a low-profile or axial air mover such as the MaxxAir AAM Pro is better suited to floor and wall drying. The AVP HP12 is at its best moving air through duct.
Tell us the space and the job and we will help you work out the duct run and set-up.
