Plug Fans
were primarily designed for installation in equipment and are mainly used in air conditioning units, hygiene equipment, clean room filter units and OEM applications. The fans are intended for conveying air and other non-aggressive gases or vapours.
Overview of designs
Plug fans are available in various designs depending on the desired installation situation.
Impeller overview
We offer various impeller geometries to achieve the optimum result for every application.
B-Series Impeller
Sizes: 250 mm – 710 mm
High-performance impellers made of aluminium (AlMg3) with backward-curved blades and a circumferential diffuser. High efficiency and pressures with a compact design for versatile applications.
E-Series Impeller
Sizes: 250 mm – 560 mm
Noise-optimized impellers made of glass fibre reinforced plastics with backward curved, profiled blades. Weight-reduced and corrosion-resistant design for volume flow-oriented behaviour.
I-Series Impeller
Sizes: 355 mm – 630 mm
High-performance impellers made of aluminium (AlMg3) with backward-curved, airfoil-profile blades and an efficiency-optimising diffuser. Noise-optimised design and volume flow-oriented behaviour for high air volumes at medium pressures.
Motor overview
Plug fans with numerous motor and wheel options offer versatile options for every application.
AC external rotor motor, offer a space-saving, compact and robust design. The motor is located inside the impeller, ensuring optimum cooling. Option with speedcontrol via frequency inverter or voltager controlare available. Belts, additional tensioning rails and motor mountings are not required. Thanks to ball bearings with long-term lubrication the motors are very easy to maintain.
External rotor motors are also characterised by an extremely low starting current. Most of the drive motors comply with protection class IP54 according to DIN EN 60034-5. The winding insulation complies with thermal class F. In addition, the winding has moisture protection impregnation as standard.
EC Motors are particularly energy-efficient, can be controlled precisely and stepless, and offer high performance in a compact design. The integrated electronics enable a wide range of control and monitoring functions and eliminate the need for expensive external control components such as frequency converters.
Thanks to their high motor efficiency, EC motors pay for themselves after a short time and offer a significantly more sustainable option than AC motors over their service life.
Plug fans with IEC standard motors offer enormous performance with high efficiency.
Different designs enable versatile options and applications. For example, the shaft design allows the motor to be mounted outside the air flow.
