Adequate air exchange and odour removal in even the smallest of grow rooms can be an expensive game, but our Budget Extraction/Filtration Kits will solve that problem for you! Everything you need is included for a fantastically low price! Based around our Budget Carbon Filters and ever reliable Systemair RVK Extractor Fans, these complete kits are incredible value in anyone's book.

Sometimes silence is important. When this is the case you can't go far wrong with our super silent silencers. These have been carefully tested and meet our approval for use with RVK Extractor Fans. Simply choose the model that matches your size of fan and attach it to the output side with fast clamps (see right - related items). All our silencers are matched for each size of fan and require no reducers to make the necessary connections.

Budget Carbon Filters are a more economic version of our standard filter range, offering equal odour removing performance but with a shorter lifespan. Designed to last up to 9 months, Budget Carbon Filters work in exactly the same way as a standard filter - connecting to one of our RVK Extractor Fans and using activated charcoal to filter out unwanted odours.

If you need less extraction during the winter than the summer or have a grow room located nearby to sleeping quarters and want to minimise air noise at the flick of a switch, you're in luck! Each unit from this innovative range of Prima Klima extractor fans features a pair of separate windings that enables you to go between two different running speeds depending on your requirements. Although the level of control on offer is not quite up to the standard of a KlimaVator, you still get a great deal of flexibility in your extraction activities and for a very cost-effective price! Prima Klima Dual Speed Extractor Fans come supplied withn a pre-wired mains lead, a wall mounting bracket and two plastic spigots that give you the option of reducing the outlet diameter when using the lower speed setting.

Humidity is a severely underrated factor when it comes to optimising plant performance and final yield. Too often indoor growers opt for the safe approach of very low humidity to avoid any potential rot or moisture related problems during flowering or fruiting. The truth about humidity though is that most plants actually thrive in more humid conditions, especially during the vegetative growth stage where ideally you need to maintain 50-70% relative humidity.

Our endless endeavours to bring you the best new products around have once again yielded exciting returns in this fantastic range of Fan Speed Voltage Controllers! While resistor-based controllers can cause fans to produce additional noise as they change speeds, these models use a variac to regulate voltage and subsequent airflow without generating noticeable side effects. Both Voltage Controllers are flexible featuring a five-speed setting that alters output by 20% intervals and come in cheaper than the Airforce models that they replace! Impressively, the 6 amp controller is also the only one we could find that even works with the largest acoustic fans!

The Klimavator is a great bit of custom designed GroWell kit. Combining a fan speed controller and thermostat, it's like having a dimmer switch for your fans with a built in temperature override. This is especially useful in the winter months as you can set your fans to 'turn over' at lower idling speeds, limiting the amount of cold air coming into your grow room. Your plants are always able to get a healthy supply of fresh air, with the adjustable thermostat ensuring that if things get too hot then your fans will 'kick in' at full speed and reduce grow room temperatures. The Klimavator can run both intake and exhaust fans but is not recommended for use with Acoustic Fans.

By creating combining the key features of an extractor fan and a fan speed controller, Prima Klima has been able to develop these forward-thinking, super effective products for ventilating grow room. With minimum fuss and maximum success, PK Temperature Controlled Extractor Fans let you manage air exchange according to your selected idling speed and grow room temperature, only switching to full speed when suitable conditions need restoring (e.g. if it's too hot). Given that UK temperatures often range from one extreme to another, the need for a flexible fan is obvious. Offering convenience, quality and user-friendly controls, PK Temperature Controlled Extractor Fans provide the simplest means of managing temperatures in single light applications. However for multiple intake and outtake fans, we do still recommend using a KlimaVator or Fan Speed Voltage Controller.

For the fastest course of action against odours and smells, the most popular move is to use an Ona Block or fragrance spray. Yet your more effective, powerful and longer lasting option comes in the shape of a Corona Plug-in Ozone Generator! Rather than introduce a temporary “cover up” scent, this small and unobtrusive product actually cleans the air to leave the surroundings feeling incredibly fresh.
