Compact external-rotor fans turn up the pressure.
When the air needed for air conditioning and ventilation is moved over long
distances, the fans being used have to work at high pressure to ensure that the required
amount of air is delivered in spite of back pressure. ebm-papst has specially adapted its
RadiPac centrifugal fan to meet these requirements.
Partial width impeller for more pressure
High outlet pressure up to: 10 in. wg
The impeller has been aerodynamically optimized and the
blade outlet width narrowed to enable the higher speeds
that result in higher pressure. The new RadiPac are
designed for high outlet pressures of up to 10 in. wg and,
depending on their size, enable flow rates of up to
approximately 8,800 cfm.
Flow rates up to: 8,800 cfm
Space-saving external rotor design
The proven external rotor design has been retained, so
the high-pressure models are also axially compact and
require little space for installation. The fans are driven by
high efficiency EC motors, which can be flexibly controlled
and intelligently interconnected. Plug & play is no problem thanks to simple connections and commissioning.
High-pressure fans
There are many situations in which fans have to work at
high pressure, including complex air distribution networks
or air ducts that have to fit in tight false ceilings and
naturally need to have small cross sections. This is also the
case for air handling units (AHUs) for hospitals that, in
addition to the complex air ducting, have HEPA filtration
to maintain their required air quality levels. Steam and
droplet separators with many pipe bends cause high
pressure losses and call for corresponding performance
from the fans used in them.
Expanded portfolio
ebm-papst has expanded its product portfolio, now supplying reliable centrifugal fans with proven EC
external rotor design for applications that have to
overcome high pressures to achieve optimum air flow.
Impeller sizes 630, 560, 400 and 355 are available now.
