Description

Systemair RVK Sileo Fans make the ideal choice for almost any hydroponic ventilation system. They have been market leaders since 1974, so years of research and experience are behind these incredible fans. They offer a level of professionalism and build quality that is hard to beat.

These fans are one of the most tried and tested on the market and even though they are not as super silent as some, their performance is considered some of the best, when it comes to the efficacy of airflow and overall reliability.

For the price, Systemair RVK extraction fans offer a great level of performance. They will fix any issues you have with high temperatures or poor airflow.

How the Systemair RVK Sileo Fans work.

The Systemair RVK Sileo Fans consists of the motor and impellors housed inside robust fibreglass re-enforced propylene casing. It is small, compact and lightweight and very easy to install, compared to most other types of extraction fans.

The wiring box is sealed to IP44 standards, this suits it perfectly for use in wet room conditions, such as humid grow rooms. Water and electrical equipment do not mix well, so choosing a purpose-built piece of equipment like these fans, removes the associated risks.

The impellor is backwards cured and carefully balanced in two levels. This provides maximum airflow rates whilst reducing vibrations and noise. With the curvature of the blades combined with the powerful motor, Systemair RVK fans will perform much better under pressure (of say attaching a carbon filter) than almost any rival. The handy mounting bracket makes installation easy. Simply connect the ducting and make sure the fan is pointed in the right direction.

How to use Systemair RVK Sileo Fans

Follow the instructions embossed under the panel of the junction box, to wire up the extraction fan to a power cable. Then connect the RVK fan to the ducting. The fan works best in an extraction system when connected to a fan speed controller.

Each uniquely sized model moves a different amount of air and are suitable for different sized areas respectively:

  • Systemair Sileo RVK 100E2 (4inch) – 184m3/h
  • Systemair Sileo RVK 125A1 (5inch) – 220m3/h
  • Systemair Sileo RVK 150A1 (6inch) – 428m3/h
  • Systemair Sileo RVK 250A1 (10inch) – 860m3/h
  • Systemair Sileo RVK 315 A1 (12.5inch) – 1360 m3/h

 

Your plants require fresh CO2 and fresh, circulating air. These fans extract hot and humid air from the highest and most central point of your grow room. The fresh air enters from lower down, through either an active intake fan or passive ventilation holes. This cycle of ventilation, with hot air out and fresh air in, maintains the temperature, humidity and CO2 levels at an optimised level for your plants.

Plants respond to a number of variants: Temperature, temperature difference (day and night), humidity and CO2 levels are the main ones related to a ventilation system. The ability to control these parameters means better control over your plant’s growth.

You cannot just look at the m3/h on the fans and choose the model based on that. Especially if you are connecting your fan to a carbon filter, you need to consider the increase in pressure this will have on the fan. When attaching a filter (or to a lesser degree, duct runs with bends in) you reduce the airflow that the fan can provide as it is essentially creating resistance to that airflow. Making sure you choose the correct size of carbon filter for the relevant fan is crucial to ensuring you have a fully functioning extraction system.

There is no one size fits all option. You need to consider the volume of your room, how much wattage of lights you have, and then other localised parameters, like if it is on a south-facing aspect of a property. Please feel free to give us a call or pop into our stores to ensure you get exactly the right model for the job.

All motors will have reduced output if more resistance is applied. These fans do not crumble under pressure and dramatically drop in airflow rates. Pressure drops when a carbon filter is attached to an extraction fan. It makes it much harder for the fan to work and the airflow will decrease, and power consumption will rise. The more pressure you create by restricting the free flow of air, the more you will notice a drop in the resultant airflow. The manufacturer of the filter you decide to use should be able to give you details of what pressure each model of filter will exert under differing airflows. Use this data and cross reference it with the data supplied by the fan manufacturer. A graph is known as a ‘pressure drop curve’ will tell you how each model of the fan will perform under varying pressures.

We recommend use alongside a high-quality fan speed controller. This will reduce noise, when operating at a lower speed and accurately control temperature. Always consider oversizing your fan (and filter) for your grow room. This will then give you the failsafe option of being able to step up your extraction come the hot summer months. If noise is a concern to you, even though these fans are not a typical ‘silenced fan,’ the addition of insulated acoustic ducting can result in the fan being nice and quiet. Finally, please ensure you have an airtight seal between any connection in your ventilation system. Making use of fast clamps provides the most suitable option to ensure no unnecessary smells escape.
