Description:
The Rosenberg Unoboxes are designed to handle air volumes from 800 m³/h to 19.000 m³/h. Typical applications are in apartments,shops,supermarkets,repair shops,warehouses, garages, etc. and other areas of slight air contamination.
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:
The housing supporting frames are double chamber aluminum profiles with corners made of plastic and double skinned (20mm) galvanized steel panels insulated with non-inflammable, noise and temperature insulating fiberglass mats. One side of the casing is open as standard.
_____________________________________________________________________________________________________
Impellers:
The impellers are balanced dynamically together with the external rotor motors at two levels according to quality level G2.5 to DIN 1940.
Up to size 450:
Backward curved centrifugal impellers made of plastic with galvanized steel support plates.
From size 500:
High efficiency backward curved centrifugal impellers made of aluminum

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 A (free inlet; free outlet) and indicate the pressure increase ∆pfa as a function of the air flow.
Noise levels:
The bordered values printed in the performance curve diagrams show the "A" weighted LWA6 sound power level (fan outlet. Determination of "A" weighted LWA5 sound power level at fan inlet:
LWA5 [dB(A)] = LWA6 [dB(A)] - 4 dB
The "A" weighted sond pressure level LpA at a distance of 1 metre is calculated approximately by deducting 7 dB(A) from the "A" weighted sound power level. It is important to note that the reflection and room characteristic as well as natural frequencies influence the sound pressure levels a different way. The relative octave sound power level LWArel at octave medium frequency you can find on the table on each fan 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.
