Prima Klima 800 m³/h Ø 160 mm
Rated at 800 m³/h through a 160 mm flange, the Prima Klima PK160-L delivers 7.3 m³/h per Watt — positioning it among the most efficient single-speed extractors in its diameter class. The ebm-papst MES AC motor with sealed ball bearings is engineered for continuous-duty operation without scheduled maintenance, while the backward-curved centrifugal impeller maintains high static pressure against inline carbon filters and extended duct runs. Flame-retardant polyamide housing rated to 50°C operating temperature and IP44 ingress protection. Dimensions 340 x 232 mm at 3.3 kg net weight. Ships with mounting bracket, cable and EU plug.

Prima Klima PK160-L – 800 m³/h centrifugal extractor: performance metrics and system sizing
Selecting an extraction fan for a larger grow space is fundamentally an engineering exercise in airflow volume versus system resistance. The Prima Klima PK160-L addresses this with an 800 m³/h rated output through a 160 mm connection, powered by an ebm-papst MES AC motor drawing 110W. Before purchasing, growers should calculate their actual airflow requirements — the sections below provide the data to make that assessment. Those requiring dual-speed flexibility can consider the Prima Klima 2-Speed 390-760 m³/h with the same connection diameter.
Airflow calculation for grow room sizing
The standard recommendation calls for a minimum of 60 complete air exchanges per hour. A 1.2m x 1.2m x 2.0m grow tent has a volume of approximately 2.88 m³, requiring a theoretical minimum of 173 m³/h. However, several real-world factors increase this baseline significantly. An inline carbon filter reduces effective airflow by 20-25%. Each metre of ducting with a 90° bend adds additional resistance. Ambient temperatures above 25°C during summer months demand faster air exchange to prevent heat stress. These cumulative factors typically double or triple the theoretical minimum. The PK160-L's 800 m³/h capacity provides substantial headroom, making it the appropriate choice for spaces running 600W HPS lighting or equivalent high-output LEDs where thermal load is significant.
Motor and efficiency benchmarks
At 110W power draw for 800 m³/h output, the PK160-L achieves an efficiency ratio of 7.3 m³/h per Watt. Running 24/7, that translates to 2.64 kWh daily energy consumption. The ebm-papst motor uses sealed ball bearings rated for continuous operation, eliminating the progressive noise increase and eventual failure associated with sleeve bearings in budget fans. The backward-curved centrifugal impeller design delivers higher static pressure than axial alternatives — a measurable advantage when the fan operates against the resistance of a Can-Lite 800 carbon filter.
- Rated airflow: 800 m³/h maximum at free flow, approximately 600-640 m³/h with inline carbon filter.
- Power: 110W at 230V, 50/60 Hz, 0.48A — daily consumption 2.64 kWh at full speed.
- Operating temperature: rated to 50°C, IP44 ingress protection for humid environments.
- Construction: flame-retardant polyamide housing, 340 x 232 mm, 3.3 kg net weight.
System integration and noise reduction
The PK160-L ships with a mounting bracket for wall or ceiling installation and a pre-wired power cable with EU plug. For complete ventilation systems, connect the extractor to a carbon filter at the intake side using rigid aluminium ducting, and route exhaust through 163 mm Sono-Connect insulated ducting to minimise sound transmission along the duct run. In noise-critical setups, add a 160 mm flexible silencer directly at the fan outlet where airborne noise is most concentrated. The combination of insulated ducting and inline silencer typically reduces perceived noise by several decibels — enough to make a meaningful difference in residential environments where the fan runs through nighttime hours.
The Prima Klima PK160-L is available at plantandflower.be with fast delivery across Belgium. Engineered for growers who size their ventilation based on data rather than guesswork.
What is the effective airflow of the PK160-L with a carbon filter connected?
With a properly sized inline carbon filter such as the Can-Lite 800, expect the PK160-L's effective airflow to drop to approximately 600-640 m³/h — a reduction of 20-25% from the rated 800 m³/h. This remaining capacity is still sufficient for grow spaces up to 1.5 m² under 600W HPS lighting when accounting for standard duct lengths and bends.
How does the PK160-L compare to a budget 160 mm fan in power efficiency?
The PK160-L's efficiency ratio of 7.3 m³/h per Watt compares favourably against generic 160 mm fans that typically achieve 4-5 m³/h per Watt. The difference stems from the centrifugal impeller design and ebm-papst motor, which move more air per unit of energy. Over a year of continuous operation, this efficiency gap translates into measurable savings on electricity costs.
Can the PK160-L be used with an external speed controller?
The PK160-L is compatible with AC fan speed controllers. Reducing fan speed lowers both noise output and energy consumption proportionally. This is particularly useful during dark cycles when heat generation from lighting drops and maximum extraction is unnecessary. Note that running below approximately 40% speed may cause motor humming in some AC controllers.
What mounting orientation works best for the PK160-L?
The PK160-L can be mounted horizontally or vertically using the included bracket. For extraction, ceiling mounting with the intake facing downward into the grow space is optimal, as hot air naturally rises. For intake applications, mount low with airflow directed upward. The fan performs identically in any orientation — the sealed ball bearings are designed for position-independent operation.
