Why Headwind HVC

Mixed flow fans sit between an axial fan and a centrifugal blower: they move a useful volume of air against the static pressure a carbon filter creates, without the size and noise of a true centrifugal. That is the whole reason this fan type dominates grow room ventilation.

EC motors, not AC

The EC range is speed-controllable across its full range without the motor hum you get from choking an AC fan with a triac dimmer. Paired with the Smart EC Fan Controller PRO, that means running at 40% overnight and full tilt at lights-on.

Silenced housings where noise matters

The EC Mixed Flow Silenced fans wrap the motor in an acoustic housing and run from 150mm to 315mm. If the fan shares a wall with a bedroom, this is the version worth paying for.

Waterproof Dura models

The Dura waterproof mixed flow fans, 100mm through 250mm, are built for damp installs — greenhouses, outdoor ducting runs and anywhere condensation is a fact of life.

How to size an inline fan

  1. Start with tent volume. Work out length x width x height in cubic metres, then aim to exchange that volume roughly once a minute as a baseline.
  2. Add back what the filter takes. A carbon filter, ducting bends and a silencer all cost airflow. Allow a meaningful margin over the raw calculation rather than buying exactly to it.
  3. Match filter diameter to fan diameter. A 150mm fan wants a 150mm filter. Stepping sizes with reducers adds restriction for no gain.
  4. Buy bigger and run it slower. A 200mm EC fan at half speed is quieter than a 150mm at full speed moving the same air, and it has headroom for summer.
  5. Decide how it is controlled. The Smart Speed Controller with thermal probe reacts to temperature; the Smart EC Fan Controller PRO gives you finer control over an EC motor.

Headwind HVC FAQ's

A mixed flow impeller pushes air both along the axis and outward, which lets it hold pressure better than a plain axial fan while staying far more compact than a centrifugal blower. That matters in a grow room because a carbon filter creates real resistance — an axial fan that looks powerful on paper collapses once a filter is attached.

EC motors are speed-controlled electronically across their whole range, so they run quieter at part load and use less power than an AC fan choked down with a dimmer. They also hold their torque better at low speed, which is why an EC fan at 40% still moves air properly instead of just humming.

Calculate the tent volume in cubic metres and start from exchanging it about once a minute, then add margin for the carbon filter, ducting bends and any silencer. As a rough guide a 1.2x1.2m tent commonly runs a 150mm fan and a 2.4x1.2m runs 200mm — but the filter and duct run matter as much as the footprint.

Only if noise is a constraint. The EC Mixed Flow Silenced fans, available 150mm to 315mm, wrap the motor in acoustic housing and are noticeably quieter than the standard version at the same airflow. If the fan sits in a garage or shed away from living space, the standard EC range does the same job for less.

Damp installations — greenhouses, outdoor duct runs, and anywhere condensation forms inside the ducting. They run from 100mm to 250mm. A standard inline fan in a wet environment will eventually fail at the motor, so if the install sees moisture, this is the version to use.

Yes. A 150mm fan pairs with a 150mm filter. Using a smaller filter with a reducer chokes airflow and shortens the filter's working life because the carbon bed is undersized for the volume. Filters here run 100x300mm, 125x300mm, 150x300mm and 200x750mm.
