Incubator Fan Kits - Upgrade Still-Air to Forced-Air for Better Hatch Rates
An incubator fan kit converts your still-air incubator into a forced-air (circulated-air) unit - eliminating the hot spots and cold corners that quietly kill hatch rates. Each kit here is matched to a specific incubator model or cabinet size, so you get the right airflow without over-drying your eggs.
We carry fan kits for the Little Giant 9300 series, HovaBator models, and high-airflow axial fans for cabinet incubators. Every kit includes mounting hardware and a full-color installation guide. No soldering, no guesswork.
Still-Air vs Forced-Air: Why a Fan Kit Matters
Still-air incubators rely on natural heat convection. Heat rises to the top and cooler air settles near the base, creating temperature differences of up to 5°F between zones. That gap is wide enough to stall development in eggs sitting in the wrong spot. A fan kit fixes this by circulating air continuously so every egg sits in the same stable temperature band.
| Feature | Still-Air Incubator | Forced-Air (with Fan Kit) |
|---|---|---|
| Temperature Evenness | Up to 5°F variance top to bottom | Within 1°F across the entire interior |
| Hot/Cold Zones | Common near lid, corners, and base | Eliminated by continuous air circulation |
| Thermostat Accuracy | Sensor reads one spot; rest may vary | Even air = thermostat reads true average |
| Hatch Rate Impact | Lower - especially in variable rooms | Higher - consistent conditions = better development |
| Best For | Small batches in stable, climate-controlled rooms | Any environment; required for cabinet incubators |
Which Fan Kit Fits Your Incubator?
Fan kits are not universal. Using the wrong kit can mean poor airflow, a bad fit, or incorrect fan speed for your model. Use the table below to find the right kit for your incubator.
| Incubator Model | Recommended Kit | Notes |
|---|---|---|
| Little Giant 9300 | Little Giant 9300 Fan Kit | Precision-matched fan and plate. Also fits 10300 and 11300. |
| Little Giant 9300 / 10300 / 11300 (with heater) | Little Giant Fan Kit with Heater 7300 | Includes integrated heater element. Best if room temperature fluctuates frequently. |
| Little Giant (older models) | Circulated Air Fan Kit for Little Giant (replaces 7200) | Replaces discontinued Miller 7200. Custom fit, plug-and-play installation. |
| HovaBator (all styrofoam models) | Circulated Air Fan Kit for HovaBator | Replaces discontinued HovaBator 7200 fan. Low-RPM design prevents egg dehydration. |
| DIY / Cabinet Incubator (110V) | Powerful Axial Fan for Cabinet Incubator 110V | 80-105 CFM airflow. Ball-bearing motor for long-term continuous use. Corner-mount holes included. |
Not sure which model you have? Check the label on the bottom or inside the lid of your incubator. If you still need help, our EGGspert team can confirm the right fit before you order.
Installation & Support
Every fan kit includes a full-color printed installation guide and a step-by-step video tutorial. Most installations take 5 to 10 minutes with a standard screwdriver. No soldering, no electrical experience required.
All kits are plug-and-play - the fan connects directly to your incubator's existing wiring. If you run into any issue during setup, our US-based EGGspert support team is available by phone and email to walk you through it.
