RVK Fans are manufactured in Germany, built to last these fans will help in the removal of hot stale air from your grow room and can also be used to provide fresh air ventilation for larger rooms. Systemair RVK inline fans are the most silent, reliable and best fans for moving large volumes of air in growrooms or greenhouses. Speed-controllable. Integral thermal contacts acc. EN 60335-2-80. Can be installed in any position. Inclusive mounting bracket. Maintenance-free and reliable. The RVK series is designed for installation in ducts. The casing is manufactured from PA6 fibreglass reinforced plastic which gives the fan a less leckage casing. Duct connected wet room applications of the fan are possible due to the air tight casing and the IP 44 rated terminal box.The fans have backward-curved blades and external rotor motors. The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibration to the duct. The fans can be speed-controlled via a stepless thyristor or a 5-step transformer. To protect the motor from overheating RVK 100E2-A1 and 125E2-A1 have integrated thermal contacts with automatic reset. The models RVK 125E2-L1 up to RVK 315 have thermal contacts with manual reset.
- Reinforced by a spiral wound wire to maintain it’s cross sectional area
- Dual-layered construction – aluminium sheath with PVC outer
- Reduced noise levels compared with single layered ducting
- Prevents light leaks
- Economical and easy to use
Combi Ducting is used to as part of your ventilation system to move air to and from the grow area, replenishing CO2 and removing excess heat and humidity. Combi Ducting has a double layered construction with an aluminium inner and a plastic outer, greatly increasing its resistance to tearing while also preventing light leaks.
Combi ducting is generally used to carry air from your extractor fan/filter to an outlet nearby. It can also be used to carry fresh air into your grow space from an inlet. It can easily be shaped around corners and will concertina down to a very short length if needed.
Combi ducting fits directly over the flange of your extractor fan or filter and the duct clamps provided will hold it tightly in place. The ducting can then be run to your air outlet/inlet. Although combi ducting works fine when run loose, the noise from air flow through the ducting will be greatly reduced if it is stretched out as much as possible. To reduce combi ducting down to the correct length, use a sharp pair of scissors to cut the PVC/aluminium sheath and a pair of sharp wire cutters to snip the spiral wire in the appropriate place.
