Prima Klima 2 Speed 450-980 m³/h
The Prima Klima 2 Speed 450-980 m³/h is the most powerful dual-speed extractor in the PK lineup. Its Ø 200 mm flange and 980 m³/h peak output are engineered for professional grow rooms running 1000W HPS or multi-lamp configurations where smaller extractors reach their limits. The low setting of 450 m³/h maintains adequate air exchange during dark cycles and cooler periods. Speed selection is via the integrated housing switch only — this dual-winding motor is not compatible with external dimmers, variispeed units or any voltage-based controllers. ebm-papst centrifugal motor, 170W, sealed ball bearings, flame-retardant polyamide housing. Available at plantandflower.be.
Prima Klima 2 Speed 450-980 m³/h – professional-grade dual-speed extraction at Ø 200 mm
There is a clear threshold where 125 and 160 mm extractors simply cannot keep pace with the thermal output of high-powered grow lighting. That threshold typically falls around 1000W HPS or dual 600W configurations in enclosed spaces. The Prima Klima 2 Speed 450-980 m³/h addresses this directly with a Ø 200 mm flange and the highest airflow in the PK dual-speed range. The integrated two-speed switch provides 450 m³/h for reduced-load periods and 980 m³/h when maximum extraction is needed. Growers working at smaller scales should consider the Prima Klima 2 Speed 420-800 m³/h with its Ø 160 mm connection as the next step down.
Choosing the right 2 Speed model: a capacity comparison
The Prima Klima dual-speed range includes three sizes, each targeting a different scale of operation. The PK125-2 at 220-360 m³/h handles single-lamp tents up to 1 m². The PK160-2 at 420-800 m³/h covers grow rooms up to 2 m² with a single 600W lamp. This PK200-2 at 450-980 m³/h extends the range to spaces of 2.5 m² and beyond under multi-lamp or 1000W setups. All three share the same dual-winding motor architecture, the same integrated switch design, and the same incompatibility with external speed controllers. The key differentiator is flange diameter and peak throughput — choose the model that matches both your duct system diameter and your worst-case heat removal requirement.
Heat removal at the 1000W scale
A single 1000W HPS lamp converts roughly 3,400 BTU per hour into heat within a grow space. Two 600W lamps generate approximately 4,200 BTU combined. These figures demand air exchange rates that exceed what 125 or 160 mm systems can deliver once carbon filter resistance is factored in. At 980 m³/h before losses, the PK200-2 provides substantial headroom. Even after accounting for 25-30% reduction from a Can-Lite 1000 carbon filter and ducting pressure drops, effective throughput remains in the 680-735 m³/h range — sufficient for maintaining target temperatures of 24-28°C in well-insulated spaces up to approximately 3 m². The low setting of 450 m³/h sustains baseline ventilation during dark periods when only residual heat from ballasts and environmental factors remains.
System design at Ø 200 mm
Scaling up to a 200 mm duct system requires matching components throughout the ventilation circuit. Connect the PK200-2 to 203 mm aluminium ducting for straight runs, or use Sono-Connect 203 mm insulated ducting where noise attenuation is a priority. The ebm-papst centrifugal motor at 170W generates higher static pressure than axial designs of comparable diameter, maintaining reliable performance through large carbon filters and extended duct routes. The fan measures 340 x 248 mm and weighs 3.96 kg. Supplied with mounting bracket, cable and plug for wall or ceiling installation in any orientation.

Is the PK200-2 compatible with a dimmer or external speed controller?
No. Like all Prima Klima 2 Speed models, the PK200-2 uses dual motor windings with an integrated switch. External dimmers, variispeed units and AC controllers are not compatible and could damage the motor. Speed selection is only possible via the built-in housing switch.
How many grow lights can this extractor support?
At full speed, the PK200-2 handles the heat output of one 1000W HPS or two 600W HPS lamps comfortably. For setups exceeding this, calculate the effective airflow after subtracting carbon filter and ducting losses and compare against your heat removal requirements. The 450 m³/h low setting is adequate for single-lamp operation or dark cycle ventilation.
What carbon filter matches the 980 m³/h output?
A carbon filter rated at 1000 m³/h or higher ensures the filter does not restrict the fan at full speed. The Can-Lite 1000 provides this capacity with the appropriate flange connection. At the 450 m³/h low setting, reduced air velocity through the carbon bed increases contact time and improves filtration efficiency.
Why choose the PK200-2 over the smaller PK160-2?
The PK200-2 delivers 23% more peak airflow through a wider 200 mm flange, enabling it to service larger spaces and higher wattage lighting. The 200 mm duct system also reduces air velocity at equivalent flow rates, lowering noise and pressure losses. Choose the PK200-2 when your setup exceeds 2 m² or runs more than a single 600W lamp.
