Prima Klima Fan 680 m3/h, 125 mm, EC motor with thermal control (PK125EC-TC)

Product detailed description

Prima Klima PK125EC-TC - quiet and efficient extract, 125 mm diameter and 680 m3/h

Prima Klima PK125EC-TC is a duct radial fan with an energy-efficient EC motor. It draws in air and easily overcomes the resistance of a carbon filter and ducting; the impeller with backward-curved blades and the aerodynamic housing made of non-flammable polyamide (nylon) keep operation quiet and reliable. The connection and control technology is integrated into the housing.

What EC motor means

EC motor (electronically commutated, from the German manufacturer ebm-papst) is a type of motor - efficient, quiet and with smooth electronic speed control built directly into the motor. Unlike a classic AC motor, the speed is not reduced by a loss dimmer, so the fan draws only as much energy as it really needs for the given airflow - even at lower speeds. The result is lower consumption, less noise and longer service life. EC refers to the motor, not the way it is connected to another device.

Built-in temperature-based control

The control unit is built directly into the fan body and is operated by three rotary controls: target temperature (range 20-30 deg. C), maximum speed and minimum speed. The fan maintains the set minimum, and when the temperature exceeds the target, it smoothly increases up to the set maximum. It handles everything on its own, without an external controller.

Why it pays off

The combination of the EC motor and built-in control means the lowest operating costs and peace of mind: the fan uses only as much energy as the given airflow requires, and noise stays at a minimum even at higher output.

Which tent it suits and how to size it

With a maximum airflow of 680 m3/h, the fan is suitable for a 120x120 cm tent or a smaller grow room. The fan diameter, filter flange and ducting should all be the same (125 mm) - otherwise unnecessary resistance, loss of performance and noise occur. A carbon filter and bends reduce the actual airflow, so choose the fan with a reserve above the space requirement.

Suitable accessories for the fan

For odour extraction, fit a same-diameter Industry carbon filter 125 mm, distribute the air with 125 mm ducting and extend the life of the carbon with the V300S pre-filter. You can mount the fan securely on a wall bracket. You can find other sizes and ranges in the Prima Klima fans category - for example, take a look at PK100EC-TC 580 m3/h, PK150EC-TC 1100 m3/h, THC version with humidity control.

Frequently asked questions

How large a tent is the fan suitable for?

The maximum airflow of 680 m3/h at a diameter of 125 mm covers a 120x120 cm tent or a smaller grow room. Allow a reserve: a carbon filter and duct bends reduce the actual airflow of the system, so it is better to choose a fan with more than enough capacity for the tent rather than exactly on the limit.

What is the difference between the -TC and -THC versions?

The -TC suffix means built-in temperature-based control: the fan increases speed on its own when the temperature rises above the set limit. The -THC version controls temperature and air humidity at the same time, so it keeps the climate within the target range (close to the VPD principle). For cultivation, humidity is just as important as temperature, so -THC is the more advanced option.

Do I need an external controller for the fan?

No. The control is built directly into the fan body, controls the speed itself and works without any additional device. Only owners of ECblue series models, which do not have built-in control, buy an external controller separately.
