Headwind HVC - Silenced Fan – Commercial-Grade Acoustic-Dampened High-Pressure Mixed-Flow Inline Extraction Fan with Integrated Speed Controller
Establish a highly controlled, biosecure nursery foundation and optimize your early-stage vegetative success rates across your entire facility with our commercial-grade Headwind HVC Silenced Fan series. Explicitly engineered to meet the rigid environmental tolerances, clean-room standards, and tight space constraints of large-scale commercial wholesale nurseries, indoor vertical farms, and advanced cultivation facilities, this specialized ventilation engine delivers exceptional climate performance. Transitioning vulnerable unrooted cuttings, tissue culture plantlets, or fragile seedlings into robust vegetative specimens requires a specialized mechanical ventilation architecture that locks in stable pressure drops and automated climate control while facilitating gentle, stagnant-free air exchange. Standard baseline inline fans are frequently too noisy, lack the static pressure to push through heavy carbon filters, or consume excessive power over continuous usage cycles. Our advanced, acoustic-dampened air processing solutions completely eliminate those operational vulnerabilities.
The core architecture of this heavy-duty extraction fan relies on an advanced, mixed-flow impeller assembly housed inside a premium, acoustic sound-dampening insulation casing, ensuring uncompromised aerodynamic mechanics that systematically outperform standard industrial blowers. Available in four strategic commercial diameters—150mm, 200mm, 250mm, and 315mm—this high-efficiency range allows cultivators to easily optimize volumetric airflow requirements, shifting effortlessly from tight multi-tier rack arrays to massive, open-air vegetative blocks. Built to run continuously under 24/7 commercial duty cycles, every unit comes fully equipped with a dedicated fan speed controller, allowing facility technicians to dial in precise air exchange volumes to match localized climate loads. Distributed exclusively in Australia by Holland Forge, the Headwind HVC series provides an impenetrable defense against operational heat pockets and stagnant, moisture-laden micro-climates.
Best For: High-pressure commercial exhaust loops, scrubbing stagnant humidity from vertical racks, whisper-quiet air exchange in urban cultivation facilities, and dedicated multi-tier ventilation lines.
Key Features & Technical Advancements
- Advanced Acoustic Sound-Dampening Housing: Outfitted with an integrated noise-absorbing insulation layer that traps high-frequency motor hum and turbulent airflow vibrations, ensuring a whisper-quiet operating profile.
- High-Pressure Mixed-Flow Engineering: Specialized impeller design builds exceptional static pressure, allowing the fan to pull air efficiently through restrictive duct runs and thick commercial carbon filters without dropping velocity.
- Integrated Precision Fan Speed Controller: Included with every model to provide immediate manual air management, allowing operators to scale down power or fine-tune air exchange volumes as environmental factors change.
- Low-Wattage High-Efficiency Performance: Engineered with premium commercial motors that maximize cubic meters per hour ($m^3/h$) output while pulling as little as 40 to 320 watts across the entire sizing index.
- Continuous 24/7 Commercial Duty Rating: Thermal protection circuitry and heavy-duty sealed bearings allow reliable, uninterrupted performance in punishing high-humidity nursery environments.
- Exclusive Australian Compliance & Distribution: Fully tailored to meet strict local electrical standards, backed by premium distribution pipelines to ensure immediate replacement parts and multi-tier facility support.

Advanced Environmental Conditioning & Ventilation Management Tips
- Optimizing Vapor Pressure Deficit (VPD) with Automated Airflow: Link your Headwind HVC fan to your centralized climate monitoring grid via the included speed controller. By modulating the fan speed down during cool periods and scaling up during peak lighting hours, you prevent rapid humidity drops, maintaining a stable 85% to 95% relative humidity envelope for unrooted tissue cultures or a consistent target VPD for advancing vegetative blocks.
- Configuring Inline Static Pressure for Stagnant-Free Scraping: When connecting your exhaust fan to a carbon filter, minimize bends in your aluminum foil or reinforced ducting. Keeping duct runs short and taut allows the HVC's high-pressure impeller to easily overcome filter resistance, efficiently exhausting stagnant, moisture-heavy air pockets away from dense lower-tier plant canopies.
- Utilizing Acoustic Housing for Close-Quarter Spatial Integration: Take advantage of the fan's sound-dampening housing by mounting it directly inside multi-tier shelving arrays or overhead rack supports. The internal insulation layer prevents motor vibrations from traveling through structural metal frames, protecting delicate plantlet plugs from physical shock and micro-frictional root stresses.
- Nursery Sanitation and Multi-Batch Fan Maintenance Protocols: Dust accumulation on inline fan blades can unbalance the impeller, increasing motor wear and reducing airflow efficiency over multi-batch cycles. Every 6 months, disconnect the fan from its power source and wipe down the intake and exhaust grids. Lightly mist a soft cloth with a 10% solution of food-grade hydrogen peroxide to sanitize the casing surface, ensuring a completely pathogen-free air handling stream.
Ideal For (Uses)
- High-Volume Commercial Nurseries: An exceptional selection for driving the primary exhaust loop across massive multi-tray propagation zones, guaranteeing consistent, clean air exchanges without disrupting sensitive plant micro-climates.
- Vertical Indoor Micro-Farms: Perfect for space-restricted urban facilities utilizing multi-tier wire racking systems, providing high-volume air extraction through tightly packed shelves while keeping ambient noise down to safe workplace levels.
- Dedicated Phenotype and Strain Hunting Lines: A reliable, ultra-quiet mechanical air processing option ideal for ventilating isolated quarantine tents, experimental breeding vaults, or small-batch genetic backups away from the main production floor.

Oversized Item Delivery Options
Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.
Available options include:
✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
Business Delivery:
- Business delivery is available for commercial customers only
- If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
- If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order

Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
