Product Overview
Most greenhouse fans are a motor and a speed switch. This VEVOR unit is closer to a controller with a fan attached. Alongside ten speed levels it carries an LCD panel and an 8.2 foot external probe, which lets it start and stop on temperature or humidity thresholds instead of running whenever it is switched on.
Airflow is listed at up to 1800 CFM from a 12 inch fan with aluminium alloy blades, aimed at greenhouses, stables, sheds, event spaces and workshops. The frame is Q235 steel and the whole unit mounts to a ceiling or wall with hardware supplied, so it stays out of the walkway rather than taking floor space.
The third mode is where it earns its keep in a greenhouse. You can schedule on and off periods from one minute up to 600, repeating for a set number of cycles or continuously, which is how you exchange air through the day without the motor running at full load the whole time.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Set high and low thresholds across 33 to 176 degrees Fahrenheit and 1 to 90 percent relative humidity, and the fan starts and stops itself.
On and off periods from one to 600 minutes, repeating for up to 100 cycles or continuously, for regular turnover without full-load running.
Gentle circulation for spring and autumn, higher speeds for summer heat exhaust, rather than a coarse three-position switch.
Metal blades instead of plastic, aimed at the warm, humid and dusty air inside a greenhouse or stable.
An 8.2 foot lead puts the sensor away from the fan's own airstream, so thresholds respond to the room rather than the outlet.
A structural steel grade for the housing, with ceiling and wall mounting hardware supplied in the box.
Accepts AC110 to 230V, so the same unit suits different regional supplies without a converter.
Design and Build Quality
The unit measures 13.78 inches long by 8.27 wide and 24.02 high, and weighs 9.41 pounds. That is a wall or ceiling fixture rather than something you move around, and the supplied mounting hardware reflects that. Finish is black.
Blades are aluminium alloy rather than plastic, which matters in a greenhouse where the air is warm, damp and often dusty. The surrounding frame is specified as Q235 steel, a common structural grade, and VEVOR calls out suitability for hot, humid and dusty areas specifically.
Electrically it accepts AC110 to 230V, so it is not tied to one regional supply. The external probe runs on an 8.2 foot lead, long enough to sit away from the fan itself, which is important because a sensor in the fan's own airstream reads the wrong thing. Model is listed as HIFANXTABLE12METALFB.
Performance in Everyday Use
Airflow of up to 1800 CFM from a 12 inch fan is the headline, and in a greenhouse the job is less about cooling air than moving it. Stagnant pockets are where heat builds and where damp sits on leaves. Ten speed levels let you run gentle circulation in spring and autumn and step up to faster air exchange through summer.
Automatic control is the part that changes how you use it. The temperature range covers 33 to 176 degrees Fahrenheit and humidity covers 1 to 90 percent relative, with high and low thresholds you set yourself. The fan then starts and stops on its own, which is the difference between a greenhouse you have to watch and one that manages itself while you are out.
The cycle timer covers the case where thresholds are not the right tool. Set anything from one to 600 minutes on and off, repeated across up to 100 cycles, or set zero cycles for continuous alternation. That suits scheduled air exchange in livestock areas and greenhouses where you want regular turnover rather than reactive cooling.
Noise is specified as at or below 60 decibels. That is not loud for this airflow, but it is not background either, and it is the main reason this belongs in a greenhouse or garage rather than next to a desk.
How It Performs: The Evidence
| Decision factor | What we found | Evidence and measurement | Score | Why it matters |
|---|---|---|---|---|
| Airflow | Up to 1800 CFM from a 12 inch fan | Listing states a 12-inch greenhouse circulation fan delivering up to 1800 CFM | 9.0 | Decides how large a space it can actually keep moving |
| Automatic control | Temperature 33 to 176 F and humidity 1 to 90 percent RH thresholds | Listing states auto mode supports those ranges and starts and stops on set thresholds | 9.5 | Turns a fan into unattended ventilation, which is the point in a greenhouse |
| Scheduling | 1 to 600 minute on and off periods, 0 to 100 cycles | Listing states that timing range, with 0 selecting continuous cycling | 9.0 | Regular air exchange without running the motor at full load all day |
| Speed range | Ten discrete levels | Listing states ten speed levels for seasonal adjustment | 9.0 | Fine steps let you match airflow to the season instead of over-ventilating |
| Materials | Aluminium alloy blades in a Q235 steel frame | Listing states aluminium alloy blades and a Q235 metal frame rated for hot, humid, dusty use | 8.5 | Plastic blades and bare steel both suffer in greenhouse air |
| Sensor placement | External probe on an 8.2 foot lead | Listing states an 8.2 ft external probe is included | 9.0 | A sensor sitting in the fan's own airflow reports the wrong conditions |
| Noise | Specified at or below 60 dB | Listing states noise at or below 60 dB | 7.0 | Determines whether you can work alongside it or only near it |
| Installation | Ceiling or wall mount, hardware included, AC110 to 230V | Listing states mounting hardware is included and compatibility with AC110 to 230V | 8.5 | Wall mounting frees floor space, and wide voltage avoids a converter |
Who Should Buy It
- Greenhouses that heat up while nobody is there
- Stables and livestock areas needing scheduled air exchange
- Garages and workshops with stagnant corners
- Sheds where damp settles on stored equipment
- Event spaces needing temporary ventilation
- Small grow tents, or anyone who wants a quiet fan running beside a desk
- Noise only specified as at or below 60 dB
- The listing's size attribute conflicts with the stated fan diameter
- Wall or ceiling fixture, so not portable once installed

Alternatives Worth a Look
A circulation fan that behaves like a ventilation controller. The thermostat, humidistat and cycle timer together mean a greenhouse can manage its own air while you are elsewhere, and aluminium blades on a steel frame suit the damp, dusty conditions. The 60 decibel figure keeps it out of living spaces, and the conflicting size attribute on the listing is worth clarifying before you buy, but for an outbuilding it does a job most fans cannot.
Frequently Asked Questions
Does it really switch itself on and off?
Yes, on either temperature or humidity. Auto mode supports high and low thresholds across 33 to 176 degrees Fahrenheit and 1 to 90 percent relative humidity, and the fan starts and stops as the room crosses the figures you set. An external probe does the measuring.
How large a space will it ventilate?
The listing quotes up to 1800 CFM from a 12 inch fan, and names greenhouses, stables, sheds, event spaces and workstations as intended uses. Airflow figures do not translate directly into square footage, so size it against your own volume and how often you want the air exchanged.
Can I set it to run on a schedule instead?
Yes. On and off periods can be set from one minute to 600, repeated for up to 100 cycles. Setting zero cycles makes it alternate continuously. That suits greenhouses and livestock areas where you want regular turnover rather than reaction to a temperature spike.
How loud is it?
The listing specifies noise at or below 60 decibels. For this airflow that is reasonable, but it is audible rather than background, which is why this suits a greenhouse, stable or garage better than a room you sit and work in.
Is the sensor built in or separate?
Separate, and that is the right design. An 8.2 foot external probe is included, so the sensor can sit away from the fan's own airstream. A sensor mounted in the outlet reads the air the fan just moved rather than the conditions in the room.
What is it made of?
Aluminium alloy blades in a Q235 steel frame. VEVOR specifically calls out suitability for hot, humid and dusty areas, which is where plastic blades warp and untreated frames corrode. The finish is black.
Does it come with mounting hardware?
Yes, the listing states mounting hardware is included and the fan is designed for ceiling or wall mounting. At 9.41 pounds it needs fixing into something solid rather than hanging from a greenhouse panel.
Will it work on my mains supply?
It accepts AC110 to 230V, so it covers both common regional supplies without a converter. Always check the plug type on the listing you are ordering from, since that varies independently of the voltage range.
Why do the size figures not match?
The product features describe a 12 inch fan while a separate size attribute on the listing quotes a different figure. We have reported only the diameter stated in the features and left the conflicting value out. It is worth asking the seller to confirm before ordering if exact diameter matters to your mounting.
This review is based on the manufacturer's stated specifications, the current product listing and its images, the confirmed dimensions, weight, airflow, control ranges and materials, and our own research into what greenhouse ventilation equipment at this level typically offers. It is editorial analysis, not laboratory testing, and we have not run this fan ourselves. The listing quotes a size attribute that conflicts with the fan diameter given in its own description, so we have reported only the figure stated in the product features and left the conflicting value out.
