Whichever way you turn it: benchmark.
The RadiPac

Impossible? Not any more!

The requirements for ventilation and air conditioning devices are constantly increasing, especially when it comes to energy efficiency. This is due to increasingly strict legal requirements, as well as the growing environmental awareness of users and the possibility of saving energy costs. The fans also need to be as quiet as possible, intelligent, and straightforward at the same time.

All of this poses major challenges for engineers. After all, every improvement in one area always means a compromise somewhere else. Can there be a fan that is impressive across the board?

ebm‑papst provides the answer with the RadiPac: not only is it powerful but also especially energy efficient, quiet, compact and intelligent. Simply the benchmark, no matter how you spin it.

The one solution for all your needs:
RadiPac

A clear advantage:
GreenTech EC technology

Simple and safe

In the RadiPac, the motor and intelligent control electronics form a single unit. There is no need for external devices, safety measures and complex adjustments. Simply connect using plug & play: that's it.

Compact and space-saving

The high-performance impeller is mounted directly on the rotor of the external rotor motor. This saves space and allows the entire rotating unit to be balanced in a single clamping operation.

Efficient and sustainable

Since the impeller, motor and electronics are optimally coordinated, RadiPac achieves efficiency levels far above efficiency class IE5, without using rare-earth magnets that are critical for the supply.

Versions and accessories

In order to suit every installation situation, the RadiPac is available in various designs – the choice is yours:

In the standard version, the most powerful motor is completely pulled out of the flow area. In the short version, the motor is immersed in the impeller. This makes the fans more compact but with a slightly lower pressure increase. However, they still offer a significant increase in performance compared with previous models.

Both RadiPac versions are available as a motor-impeller combination or as a ready-to-install plug & play solution in a compact support bracket. The support plates are dimensioned to make the best possible use of space on a Euro pallet. This saves transport costs and improves the CO₂ footprint.

In addition to the aerodynamically optimized plastic impeller, ebm‑papst also offers its RadiPacs with metal airfoil blades. They are particularly robust and are suitable for applications in which large volumes of air need to be moved. As with all RadiPacs, the complete plug & play system impresses with outstanding system efficiency – available in all standard sizes from 250 to 1,000.

The fans are also available with the FlowGrid air inlet grille, which works like a rectifier and reduces noise-generating turbulence in the inflow. The air performance and power consumption remain unchanged. In the completely enclosed version, the FlowGrid is also used as a guard grill.

EC fans are used on a large scale to ensure that the heat generated in data centers is dissipated efficiently. In order to avoid overdimensioning the power supply and to meet the corresponding requirements with regard to current and voltage harmonics, ebm‑papst has developed the 3-phase active PFC fan.

The approach of the 3-phase active PFC fan technology from ebm‑papst is to prevent current harmonics from occurring at all instead of filtering them out afterwards with additional components, which involves a lot of effort.

For ventilation and air conditioning in large buildings, the air often has to travel long distances through external pressure elements and angled air ducts. Our RadiPacs, which are specially optimized for these requirements, deliver a static pressure increase of up to 2,500 Pa and air performance levels of up to 15,000 m³/h. They are available in sizes 355, 400, 560 and 630, with support bracket or cube design as required.

RadiPacs with additional corrosion protection measures are available in sizes 250 to 800 – with support bracket and cube design. In these versions, all metal surfaces have an additional coating.

ebm‑papst offers specially protected ATEX versions for use in potentially explosive atmospheres of zones 1 and 2. These are available in sizes 400 to 630.
