Leipole EC fans combine an electronically commutated (EC) motor with a ball-bearing axial or centrifugal impeller for efficient, quiet and long-life cooling of electrical enclosures, control panels and electronic equipment.
All models run on AC 230V with a wide 50~400Hz input frequency range and are CE certified. The range covers axial fans from 120 to 2200 m³/h and IP44 centrifugal fans from 300 to 2200 m³/h, so you can match the airflow to the heat load of your enclosure.
Choose the control function that fits your system: RD (rotation detection alarm output), RD+PWM (rotation detection with PWM speed control) or FG+PWM (frequency generator signal with PWM speed control). The EC Master LP17251-6.0 controller can regulate fan speed automatically from cabinet temperature.

Function suffixes: HR / VR = RD · HRP / VRP = RD+PWM · HFP = FG+PWM
Frequently asked questions
What does EC mean, and how is an EC fan different from an AC fan?
EC stands for electronically commutated. An EC fan has a motor with built-in control electronics, so its speed can be set electronically (for example with a PWM signal) instead of running at one fixed speed. Standard AC fans run at a fixed speed; see our AC fans for that range.
What do RD, RD+PWM and FG+PWM mean in the model name?
RD means rotation detection: the fan provides a signal so your system can detect a stopped or abnormal fan. RD+PWM adds PWM speed control. FG+PWM combines a frequency generator (FG) speed-feedback signal with PWM speed control. In the model code, HRP/VRP means RD+PWM, HR/VR means RD, and HFP means FG+PWM.
What supply voltage do EC fans need?
All EC fans listed here run on AC 230V and accept an input frequency of 50~400Hz. If your equipment is powered by 24V DC, see our DC fans.
Should I choose an axial or a centrifugal EC fan?
Axial fans (F2E series) move air straight through the fan and suit panel-mounted ventilation. Centrifugal fans (FLW2 series) are rated IP44 and are the usual choice where higher pressure is needed, for example when air must be pushed through a duct or filter. Check the airflow and dimension columns in the tables above against your enclosure.
How do I choose the right size and airflow?
Match the fan airflow to the heat load and the allowed temperature rise of your enclosure. You can use our airflow calculator, or contact our technical support with your enclosure details and we will recommend a model.
Can fan speed follow the cabinet temperature automatically?
Yes. The EC Master LP17251-6.0 is a dual-channel controller that reads a temperature sensor and adjusts fan speed with a PWM signal. It covers a 0~70°C control range and can control two separate fan groups at the same time.
Are EC fans certified?
Yes. The EC axial and centrifugal fans in this range are CE certified.
How do I request a quotation?

Selection & support
Selecting LEIPOLE EC fans
Match airflow, control function and installation space before confirming an EC fan model.
When should I choose an EC fan instead of an AC fan?
EC fans suit cabinets that need electronic speed control or rotation feedback. Confirm the AC 230V supply, the RD, RD+PWM or FG+PWM function, and the mounting space available in the enclosure.
How do I narrow the EC fan model list?
Use the airflow calculator to estimate required airflow, then compare the airflow, dimension and function columns in the tables above. Include ambient conditions and heat load in any inquiry so the team can review the shortlist.
