The 160 mm Prima Klima inline fan is the centrepiece for controlling the air in your grow tent. With two speeds (420 and 800 m³/h) and a built-in switch, it removes hot, humid air, tackles odours when paired with a carbon filter, and keeps a healthy climate for your indoor plants.

The integrated switch lets you move between 420 m³/h and 800 m³/h depending on your grow stage, then cut the motor with the OFF position. You match air renewal to the heat of your grow lights without any extra hardware.
By exhausting hot, humid air, the fan stabilises the temperature and humidity of your grow space. Constantly refreshed air limits the risk of mould and supports vigorous vegetative growth and flowering.
Prima Klima is a benchmark in indoor ventilation. This robust motor delivers steady, long-lasting performance, designed to run for long hours season after season without losing power.
Mount it as an extractor to push out stale air, or as an intake to bring in fresh air. That versatility makes it an asset for any ventilation setup, from a simple tent to a full kit with carbon filter and ducting.
At 800 m³/h on high speed it suits medium to large grow rooms. For proper air renewal, aim to turn over your room's volume several times per hour; the 420 m³/h setting fits smaller spaces or cooler periods.
Can I use it with a fan speed controller?No. This model has its own two-speed switch and is not compatible with an external thermostatic controller or variable-speed regulator. You set the power directly via the built-in switch.
Do I need a carbon filter with this fan?To neutralise odours, pair it with a Ø160 mm carbon filter placed upstream. The fan then draws air through the filter and exhausts deodorised air. Plan for matching-diameter ducting to connect everything.
One unit to extract, ventilate and purify: the Prima Klima 160 mm fan is the foundation of a healthy, productive indoor grow.
