Description:
Tube fans represent a technically perfect solution, uniting the advantages of axial fans, straight airflo w and easy installation, with high pressure stability, low noise level and high efficiency of the radial fans.
Application areas:
Garage / Offices / Bars / Greenhouses / Skyscrapers / Hotels / Industrial buildings / Basement rooms / Playschool / Cinemas / Parking facilities / Warehouses / Nursing homes / Schools / Sports halls / Supermarkets / Workshops / Residential houses / Fitness centers / Inflatables
Reference to Directives:
Declaration of incorporation and operating instruction are according to Machinery Directive 2006/42/EC, CE identification in accordance to EMC-Directive 2014/30/EU, Low Voltage Directive 2014/35/EU and the Ecodesign-Directive 2009/125/EC.

Casing:
Steel type (R)
The casings are manufactured of galvanized sheet steel
Plastic type (RS)
The casings are equipped with an attractive and hardly inflammable plastic casing with integrated IP44 terminal box and guide vane.
Advantages of the plastic types compared to sheet steel types:
- lower noise level
- completely corrosion resistant
- easy installation with mounting brackets
- higher pressure and better efficiency through guide vane

Impellers:
The impellers are balanced together with the external rotor motors at two levels according to quality level G2.5 to DIN 1940.
Type R:
100-250 = backward curved centrifugal impeller made of plastic
250L-315M = backward curved centrifugal impeller made of galvanized sheet steel
from 355 = backward curved centrifugal impeller made of aluminium
Type RS:
100-250L = backward curved centrifugal impeller made of plastic
from 315 = backward curved centrifugal impeller made of galvanized sheet steel

Motor and motor protection:
All Rosenberg fans are equipped with direct driven external rotor motors. All our fans have motor protection through thermal contacts in the motor windings as standard. The motors apply to protection class IP44/IP54.
The drive has due to an external rotor motor a space saving, compact and attractive design. The motor is fitted within the impeller, which enables the best possible cooling. For this reason a 100% variable speed control can be guaranteed. V-belts, additional tension bars and motor mounting devices are not necessary. Only well-dimensions ball-bearings, fitted on both sides and life time greased are used.
Both ball-bearing seats are ground to high precision in one work process to eliminate any vibrations.
External rotor motors have extremely low starting currents. The windings comply to isolation class F.
In addition the windings have a standard moisture impregnation.

Important notes:
Air performance curves:
The performance curves for these fan types have been measured in mounting position D (installed on the pressure side and open on the suction side) and show the total pressure increase ∆pt as a function of the air flow. The dynamic pressure ∆pd2 refers to the flange cross section at the outlet side of the fan.
Noise levels:
The bordered values printed in the performance curve diagrams show the "A" weighted LWA6 sound power level at the outlet side in duct systems. The relative octave sound power level LWArel at octave medium frequency you can find on type page.
Classification of the fan series:
NRVU = Non Residential Ventilation Units
UVU = Unidirectional Ventilation Units
Erp-Information:
Rosenberg fans have a spezfic (pressure-) ratio < 1,05 (pressure < 5000 Pa).
Service life:
For maximum service life of Rosenberg products please beware of the maintenance hints on the manual for each product type.
Recycling and disposal:
For recycling and disposal of Rosenberg products comply with applicable locally requirements and regulations.
Tube fans with casing made of plastic
The casing of the RS series is made from shock-proof, recyclable black plastic (PA 6.6 + GF) with integrated terminal box and the possibility to mount a bracket. Inlet and outlet side with duct connection for standard round ducts can be mounted in any position. Both ranges with backward curved impellers made from plastic, size 355 L made from aluminium and with speed controllable external rotor motor, fitted into the impeller. The fans are balanced according to quality level G 2.5, DIN/ISO 1940 on two levels. Motor closed, protection class IP 44/54, with thermal contacts, wired in series in motor windings from size R 355 L. Maintenance free ball bearings, closed on both sides, sealed for life.
