Description
Temperature and humidity-controlled air extractor
This extractor with hygrostat and thermostat, has a maximum capacity of 680 m³/h. This makes it ideal for grow rooms where both temperature and humidity are key factors that need to be kept under control.
Operating the extractor fan with hygrostat and thermostat is very simple. Just like the version with a thermostat only, the PK125EC-THC also has an adjustable minimum and maximum speed. Use the temperature control knob to set the desired temperature in the grow room and the humidity control knob to set the desired humidity level.
As soon as the temperature or humidity in the grow room exceeds the desired set value, the extractor will run at the set maximum speed. If the temperature or humidity falls below the set desired value, the extractor will run at the set minimum speed.
LED lights on the extractor fan indicate whether it is running at minimum or maximum speed.
Example:
You have set the maximum fan speed to 50% and the minimum fan speed to 50% as well. You have set the temperature to 27°C and the humidity to 75%. If the temperature in the grow room rises above 27°C or the humidity exceeds 75%, the extractor fan will run at 50% of its total capacity = 340 m³/h. If the temperature drops below 27°C or the humidity falls below 75%, the extractor fan will run at 50% of the set maximum speed. So 50% of 50% = 25% = 170 m³/h.
Energy-efficient
The PK125 EC-THC extractor fan with hygrostat and thermostat is fitted with an EC motor from EBM Pabst. These are particularly energy-efficient, especially when the motor is running at a reduced speed.
The table below shows the savings in power consumption at different dimming levels:
| Running speed | Savings |
| 75% | 49% |
| 50% | 77% |
| 25% | 94% |
Silent
As well as being energy-efficient, the PK125 EC-THC is also exceptionally quiet. The impeller with its backward-curved blades and the aerodynamic design of the housing of this extractor fan with hygrostat ensure virtually silent air movement. Furthermore, the motor produces no annoying humming noises when running at a reduced speed.
