RAM AIR-PRO II Controller – Intelligent Temperature & Fan Speed Control · Silent Climate Management

Take absolute control of your indoor garden's climate with the RAM AIR-PRO II Controller, an intelligent thermostat and fan speed manager designed to automatically maintain the perfect temperature and negative pressure without lifting a finger.

Are you tired of constantly battling temperature spikes and drops that stress your plants and ruin your yields?

Manually adjusting your intake and exhaust fans is a nightmare. If you get it wrong, you lose negative pressure, letting those telltale odors escape your grow space, while your fans run at max speed, sounding like a jet engine and skyrocketing your electricity bill.

The RAM AIR-PRO II is the ultimate brain for your Climate Control system. Just plug in your fans, set your ideal temperature, and this smart device will automatically calculate and modulate the exact fan speed needed to keep your grow room stable, silent, and perfectly balanced.

Effortless Climate Management for a Perfect Grow Room

Imagine stepping into your grow room and knowing the environment is dialed in perfectly, 24/7. With this intelligent controller, you no longer have to guess or tweak dials every time the lights turn on or off. It learns the optimal speed for your specific setup, ensuring your plants thrive in a stress-free environment.

By maintaining a constant negative pressure, it also guarantees that all the air is forced through your carbon filter, keeping your operation completely discreet. Plus, the digital display makes it incredibly easy to monitor what's happening at a glance, giving you total peace of mind so you can focus on what really matters: growing massive, sticky buds.

How to Set Up and Use the RAM AIR-PRO II Controller

Setting up this device is a breeze, even if you aren't a tech wizard. Follow these simple steps to automate your ventilation:

1. Placement: Mount the controller outside your grow tent to protect it from high humidity, and place the 2-meter remote thermostat sensor right at the canopy level of your plants.
2. Connection: Plug your exhaust fan into the designated outtake socket and your intake fan into the intake socket.
3. Power up: Connect the 2-meter power cable to a standard wall outlet and turn on the digital display.
4. Set your targets: Use the interface to dial in your desired room temperature and the minimum fan speed/balance you want to maintain.
5. Let it learn: The intelligent software will take a few moments to calculate the optimal running speed, modulating the fans to lock in your exact settings.
6. Mistake to avoid: Do not place the temperature sensor directly under your grow lights or right next to a fan, as this will give false readings and mess up the automation.

Key Advantages and Benefits of the RAM AIR-PRO II

• Intelligent speed modulation: It automatically calculates and adjusts to a single, optimal running speed, which means your climate stays perfectly stable without sudden, stressful temperature swings.
• Independent twin fan control: Manages both intake and exhaust fans simultaneously, allowing you to easily maintain negative pressure so no unwanted odors ever escape your grow space.
• Noise reduction technology: Limits excess airflow and prevents fans from running at 100% unnecessarily, which means you get a whisper-quiet operation that won't attract unwanted attention.
• Energy efficiency: By only using the exact amount of power needed to maintain the climate, it significantly lowers your electricity consumption, saving you money on your monthly bills.
• Extended equipment lifespan: Smoothly ramping fan speeds up and down reduces mechanical wear and tear, meaning your expensive inline fans will last much longer.
• Universal compatibility: Designed to work seamlessly with most sizes and brands of extraction fans, giving you the flexibility to upgrade your setup without needing a new controller.

Maintenance and Care for Your Climate Controller

To keep your RAM AIR-PRO II functioning flawlessly harvest after harvest, keep the main unit away from direct water splashes and extreme humidity. While the sensor is designed to be inside the grow room, the digital brain should ideally sit outside your Grow tents to ensure maximum longevity.

Wipe the digital screen occasionally with a dry microfiber cloth to keep it readable. Also, make sure to check the 2-meter sensor cable periodically to ensure it hasn't been pinched or damaged by your Air Extraction System setup.

Frequently Asked Questions

Can I use the RAM AIR-PRO II with just one exhaust fan?

Yes, while it is designed to balance two fans (intake and exhaust) for optimal negative pressure, you can absolutely use it to control a single exhaust fan to manage your room's temperature.

Does this controller cause a humming noise in the fans?

Unlike cheaper controllers that cause a loud magnetic hum when dimming fans, the RAM AIR-PRO II uses advanced modulation technology to keep your fans running smoothly and quietly.

How long is the temperature sensor cable?

The device comes with a 2-meter remote thermostat sensor, giving you plenty of length to position it perfectly at the canopy level of your plants.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested dozens of climate controllers over the years, and the RAM AIR-PRO II is honestly one of the smartest investments you can make for a mid-to-large indoor setup. What I love most is its 'learning' feature. Instead of aggressively revving the fans up and down like older models, it finds that sweet spot and just hums along, keeping the temperature rock solid. It’s a game-changer for maintaining negative pressure, especially when you're growing some seriously pungent strains.

The only minor drawback is that the 2-meter power cable might require an extension cord if your wall outlets are far from your tent, but that's an easy fix. My personal trick? I always set the minimum fan speed just high enough to keep a gentle breeze moving through the canopy even when the lights are off; it works wonders for preventing mold while keeping the climate dialed in.
