Phresh Hyperfan (100mm / 125mm / 150mm / 200mm / 250mm)

What is the Phresh Hyperfan and why do people choose it?

Phresh Hyperfan is a mixed-flow EC inline fan designed for high airflow and strong static pressure. It’s built to handle restrictive setups like carbon filters, long ducting, and air-cooled hoods, while using less power and making less noise than typical inline fans.

Is Phresh Hyperfan an EC fan and what are the benefits?

Yes—Phresh Hyperfan uses a digital EC (electronically commutated) motor, which allows smooth, efficient speed control and quieter performance compared to AC fans. It’s ideal for precision airflow in grow tents and other controlled environments.

Does Phresh Hyperfan come with a speed controller?

Yes—it includes a manual speed controller. If you want temperature-based automation, it supports 0–10V controllers (like Gavita ELF) and some smart climate controllers, depending on cabling and compatibility.

Can Phresh Hyperfan be used for both intake and exhaust?

Absolutely. It works for intake or exhaust—just install it in the correct airflow direction. It’s also built to handle carbon filters, backdraft dampers, and air-cooled reflectors with minimal performance loss.

How loud is Phresh Hyperfan and how can I reduce noise?

Phresh Hyperfan is quieter than many inline fans, but install matters. Use hanging straps (not hard mounts), avoid sharp duct bends, seal all joints, and run the fan at the lowest effective speed to reduce noise and vibration.

What sizes are available and how do I choose the right one?

Phresh Hyperfan is sold in 100mm to 250mm sizes. Choose based on tent size, filter resistance, and duct length. Many growers size up and run at lower speeds for quieter, more efficient operation with room to scale.

Will Phresh Hyperfan help control temperature, humidity, and odour?

Yes—Phresh Hyperfan improves air exchange, which helps lower heat and humidity (if incoming air is cooler/drier) and maintains negative pressure for odour control when used with a carbon filter.

Why does my airflow feel weak or my tent collapse?

Check for filter clogs, ducting kinks, not enough intake area, or excessive exhaust speed. A collapsing tent usually means strong negative pressure—open passive intakes or reduce speed slightly.

Why does my Phresh Hyperfan run at full speed or not respond to my controller?

This usually means a controller or wiring issue. Try the included manual controller first—if that works, your other controller may be incompatible, miswired, or missing the correct 0–10V signal.

How should I mount Phresh Hyperfan in my setup?

It can be mounted horizontally or vertically using straps or brackets. Many growers mount it outside the tent to reduce heat and save space. Always secure it well and avoid twisting the housing with ducting.

Does Phresh Hyperfan require maintenance?

Minimal. Keep prefilters clean, check for dust buildup near the impeller, and listen for any changes in fan sound. Clean monthly if your environment is dusty. Bearings are high-quality, but vibration or noise changes can indicate wear.

Can Phresh Hyperfan be used for drying, greenhouses, or CO₂ setups?

Yes—it’s great for steady, low-noise ventilation in drying rooms, greenhouses, and sealed environments. If supplementing CO₂, plan venting carefully to avoid exhausting your enrichment too quickly.

What comes with the Phresh Hyperfan?

You’ll get the fan and a detachable speed controller. Some kits include specific adapters (like for Gavita), but not all—always check what’s included in your order if you need third-party controller integration.

Is Phresh Hyperfan worth the cost compared to cheaper inline fans?

Yes—especially in filter-heavy or 24/7 setups. It offers better airflow under pressure, smoother control, and higher efficiency. Over time, you save on power and enjoy a quieter, more reliable system.

What’s the biggest mistake people make with Phresh Hyperfan?

Using the wrong controller or cable, then thinking the fan is faulty when it runs at max speed. Always start with the included manual controller, and check your control gear is truly 0–10V compatible before wiring.
