      Headwind HVC — EC Inline Fans Built for Serious Growers

      Headwind HVC makes EC inline fans designed from the ground up for indoor growing environments. Their mixed-flow technology delivers high static pressure with low noise — the kind of airflow performance that matters when you're running carbon filters, managing heat, and keeping humidity dialled in. The Grow Guys stocks Headwind HVC because they give growers real EC fan performance at a price point that actually makes sense. Free shipping over $499*.


      Why growers rate Headwind HVC

      EC Performance Without the Premium Price Tag

      EC Motor Efficiency
      Electronically commutated motors use significantly less power than standard AC fans at equivalent airflow. Better performance on the electricity bill, not worse.
      Mixed-Flow Design
      Mixed-flow impellers balance high static pressure with strong volume output — critical when running a carbon filter inline. The fan handles resistance properly, not sluggishly.
      Built-In Noise Dampening
      The silenced HVC range uses acoustic insulation inside the housing to cut operational noise — ideal for tents in living spaces or spare rooms where volume is a real consideration.
      Speed Controller Included
      Every HVC fan ships with a speed controller as standard. No extras to buy just to dial in your airflow from day one.
      Sizes for Every Setup
      From 100mm compact tents to 315mm high-volume extraction running nearly 3000 m3/h, the range scales from small propagation spaces to large-format grow rooms.
      Smart Controller Ecosystem
      Step up to HVC's Smart EC Controllers for automated temperature and humidity management, day/night scheduling, and the ability to run multiple fans from a single unit.

      About Headwind HVC

      EC Fan Technology for Modern Grow Rooms

      Headwind HVC set out to do one thing well: bring EC fan technology into indoor growing without the price premium that typically comes with it. EC (electronically commutated) motors are a meaningful step forward from older AC fan designs — more precise speed control, better energy efficiency, and quieter operation across the entire speed range. HVC built their fan line around that technology and made it accessible to growers at every scale, from first-time tent growers to operators running serious multi-light setups.

      Their silenced mixed-flow fans sit at the core of the range, combining a mixed-flow impeller for strong static pressure performance with acoustic dampening materials throughout the housing. The result is a fan that handles carbon filter resistance properly while running quietly enough for environments where noise matters. Available from 100mm through to 315mm, the range covers a small clone tent all the way through to a large-format commercial grow room without compromise. The Dura series adds IP68 waterproofing for setups where moisture and splashback are part of the reality.

      The HVC controller ecosystem extends the platform further. The basic speed controller that ships with every fan handles manual control, while the Smart EC Controller and Smart EC Controller PRO bring automated temperature and humidity management, day/night programming, and multi-fan capability into a purpose-built unit. For growers who want their environment to manage itself — particularly through lights-out periods — the PRO controller is worth the step up.

      What Headwind HVC Makes


      Grow Guys Tip

      EC fans don't need to run flat out to be effective — and with HVC fans, they shouldn't. Running at 70–80% keeps noise low, extends motor life, and moves more than enough air for most grow tents. Save the top end of the speed range for summer heat events or when you're pushing serious wattage in a tight space. If you're using the Smart Controller, set your target temperature and let the fan find its own level rather than pinning it at max from the start.


      Common Questions

      Headwind HVC — FAQ

      Does the Headwind HVC fan come with a speed controller?
      Yes — every Headwind HVC inline EC fan includes a basic speed controller in the box. If you want automated temperature and humidity control, the Smart EC Controller and Smart EC Controller PRO are available separately and support multiple fans running from a single unit.
      What size Headwind HVC fan do I need for my grow tent?
      As a general guide: 100mm suits tents up to around 1m x 1m, 150mm handles 1.2m x 1.2m & 1.5m x 1.5m setups, and 200mm covers most 1.5m x 3.0m spaces comfortably. For larger tents or setups running high-output lighting, step up to 250mm or 315mm. Factor in your carbon filter — EC fans handle filter resistance well, but sizing up slightly is always safer than sizing down.
      Is the Headwind HVC silenced fan actually quiet?
      Yes — at mid-range speeds the acoustic insulation inside the silenced HVC housing makes a real, noticeable difference compared to older AC fans of comparable output. At full speed it's still an extraction fan doing its job, so expect some noise — but nothing unusual for the category. For the quietest operation, pair it with the Smart Controller and let it run below 80%.
      Can I use the Headwind HVC fan with a carbon filter?
      Yes — HVC fans are well-suited to carbon filter pairings. The mixed-flow impeller handles the static pressure resistance a filter creates without the airflow drop you get from axial fans under load. HVC also makes their own carbon filter range sized to match their fans, which removes the guesswork from compatibility entirely.
