Ram Air-Pro II Fan Controller

Description

The RAM AIR-PRO II Fan Controller is an intelligent, silent indoor climate controller. Designed to control two inline/exhaust fans by monitoring and keeping the desired room temperature and air pressure.

All you have to do is plug in your fans. Set the required air temperature and fan speed/balance and the AIR-PRO will do the rest. Maintaining temps in your room and giving you full control over negative pressure.

The AIR-PRO II features a remote thermostat sensor and temp setting, as well as twin fan speed control.

This intelligent fan speed controller learns your optimum speed for the temperature/pressure that you desire. The unique software will calculate the running speed for your fans and learn from this. It then modulates them (ramp down) to a single running speed that maintains the required temp that you have set. A remote probe is fitted, accurate to within +/- 1 degree, that can be placed in the key temp sensitive area.

The RAM AIR-PRO II looks for a stable fan speed to maintain the desired temperature. This means that your fans will be running below the maximum operating speed. They will be operating at max efficiency with regards to power vs performance. This extends fan motor life, while only using the minimum power needed.

TIP: For best results, use the AIR-PRO Fan Speed Controller with RAM Inline Fans 100mm to 315mm, however it can be used with other brands to the equivalent size.

DO NOT exceed maximum load.

Specification:

1 x 2m remote thermostat sensor
Variable temperature control
Variable fan speed control
Digital display
1 x 2m power lead
Up to 7 amps per socket

What Size Fan Do I Need?

Choosing the right extractor fan for a grow is so important and so easy at the same time. Providing your plants with fresh air constantly is a must for growing quality cannabis. Plants use carbon dioxide and expire oxygen during the day, while using oxygen and expiring carbon dioxide at night. Air in a grow room or tent becomes stale quickly and of no value to plants if not refreshed regularly.

RAM In-Line duct and RAM Mixed-Flow Inline Fan expel old hot air and replace it with fresh, cooler CO2 rich air. This needs to happen every two minutes to keep indoor plants happy. It seems like a lot of air but it really isn’t that hard to accomplish.

Calculating the Volume Of Your Grow

To make sure you select the right fan for your grow, start by working out the volume of your grow room or tent. Multiplying the length by the width and by the height will give you the volume. We’ll use the Lighthouse LITE 1.2m Tent as an example:

1.2m x 1.2m x 2m = 2.88m3 (volume of tent)

Multiply 2.88 by 30 if we are to replace the air in the room every two minutes. This number is then used to compare with fan ratings to select the right extractor fan.

2.88 x 30 = 86.4m3/h

The 86.4 cubic meters of air an hour is the very minimum volume of air your extractor fan needs to move. This will replace the air in the tent every 2 minutes. Avoid problems by selecting a fan rated slightly more than your needs.

Choosing The Right Fan And Filter

Control the smell of a cannabis grow by using a carbon filter. Note that using a filter will hinder the fan’s capability to move air by around 20%. Like fans, carbon filters have different ratings or volume of air they can filter per hour. It’s better to choose one rated slightly better than the fan. By doing this, fans don’t work too hard and will last longer on average.
