Prisen for energi fortsætter med at stige og kravene om energibesparelser øges for alle områder.Internationale miljøaftaler vil snart ændres fra vejledende til lovkrav.Energi-effektive produkter vil få deres egne klassifikationer som en del af direktivet for energi brugende produkter (Energy-using products Eup). Det er derfor en fornuftig ide at lave smarte energi effektive løsninger i dag.
Valg af korrekt ventilator er økonomisk og energibesparende.
Bygninger forbruger ca. 40% af alt energi inden for EU. Den samlede andel af ventilation udgør ca. en tredjedel af alt energi forbrug i bygninger og ventilatoren står for den klart største
Den samlede effektivitet er den bedste indikator af energieffektiviteten for en ventilator. En nyttig måling er SFP (Specific Fan Power). Dette er ventilatorens samlede elektriske forbrug divideret med ventilatorens luftmængde (SFP=PE/qv=kw/m³/s) SFP målingen er et godt sammenlignings- grundlag for ventilatorer af forskellige producenter, forudsat at det totale elforbrug er udregnet ens. Når man dimensionerer det ”Specifikke Fan Power” bør følgende overvejes: - Ventilators virkningsgrad i driftspunkt - Motor effektivitet også ved delbelastning - Hastighedsregulators virkningsgrad og dennes påvirkning af motor.

The schedule of ErP regulations
The first phase (tier 1) comes into force on the 1st January 2013.
The regulation sets out minimum efficiency grades for fans within its scope being placed on the market for the first time. The efficiency grade is based on the electrical input power and therefore encompasses both the fan efficiency and the motor efficiency.
Any fan placed onto the market for the first time (usually by the manufacturer) will have to comply with these efficiency grades. It will be illegal to introduce a fan onto the market after 2012 that does not comply.
A second phase (tier 2) of tighter efficiency grades will come into force on the 1st January 2015.
The second stage with higher efficiency values becomes e�ective on January 01, 2015, and this will consider the entire fan, not just the fan motor.
Fan regulations
The regulation sets out minimum efficiency grades for fans within this scope being placed on the market for the first time. The efficiency grade is based on the electrical power from mains and therefore encom -passes both the fan efficiency and motor efficiency. Any fan placed on the market for the first time will have to comply with these efficiency grades.
For classification of fans efficiency, grade N has been generated (in international ISO standard the symbol is FMEG).
Depending on the model of the fan, the efficiency grade N in accordance with ErP Directive must be complied.
The efficiency grade can be measured for complete fan system or calculated by using algorithms defined within regulations.
How the efficiency is calculated?
The EU has specified the corresponding formulas with which the respective mini -
mum efficiency for axial fans, forward and backward curved centrifugal fans, tangential blowers and diagonal fans can be calculated
FW fans meets ErP regulation already now
How does the ErP Directive a�ect fans?
Several models used to date do not meet the require -ments and have therefore been revised or taken o� the market. It has been illegal to introduce a fan onto the market after 2012 that does not comply.

European Energy Related Products Directive (ErP)
Following the Kyoto protocol the EU has set a target to reduce energy consumption by 20%, and increase the share of renewable energies by 20% by 2020. With ErP Directive the EU has defined the way to do this.
Because of ErP directive for fans, fan manufacturers will be required to design their products for the European market to comply with defined efficiency standards to make an important contribution to reducing energy consumption.
For this reason applicable regulations and standards have been developed for di�erent product categories within EU. For fans with input power between 125W and 500 kW the Commission’s Regulation 327/2011/EC is applied.
The user can recognize fans that satisfy the requirements of the directive by the CE sign.
World record fan, Centrifl ow Plus PM maximizes the advantages of permanent magnet motor technology.
The new Centrifl ow Plus PM provides highest effi ciency in a small and compact design.
The new PM motor range with optimal and effi cient airfl ow through our impeller.
Centrifl ow Plus PM: highest effi ciency through a wide range of power and airfl ow.
Centrifl ow Plus PM provides highest total effi ciency including fan, motor and drive.
When launched the Centrifl ow Plus plug fan broke the world record in effi ciency, its successor the Centrifl ow Plus EC, broke the record again. Now our new Centrifl ow Plus PM puts the previous records into history and lifts the record once again to a new higher level!
Taking advantage of new permanent magnet motor technology with improved motor effi ciency, also having optimized the airfl ow through our impeller, we have improved the total fan motor effi ciency by up to 6%.
Improved aerodynamics with a higher overall effi ciency and thus a lower power consumption, all in a smaller more compact size.
Motors are available in the power range from 0.75 up to 22 kW o�ering airfl ows up to 10 m3/s and pressures up to 1500 Pa.
The overall footprint of the Centrifl ow Plus PM fan is smaller due to the compact PM motor dimensions.0 500 1000 1500 2000 2500 35003000

Totalverkningsgraden baserar sig på det välkända CENTRI--
netmotor. Moderna permanentmagnetmotorer har en hög verkningsgrad och den bibehålls även då motorn körs med lägre varvtal. De övriga välkända egenskaper hos Roofmaster STEF har vi behållit. Ljudnivån är låg och Roofmaster Plus EC är lika montage -

Mångsidiga regleringsalternativ
Behovet av ventilation varierar kraftigt över dygnet och årstiden. Med behovstyrd ventilation sparar man i driftskostnader. Roofmaster Plus EC har en inbyggd varvtalsregulator och varvtalet kan styras steglöst med en 0 till 10V styrsignal eller manuellt med en po -tentiometer. Det är också möjligt att köra med en eller två fasta varvtal. En tryckreglulator kan kopplas till Roofmaster Plus EC för att få konstanttryckstyrning. Tryckregulatorn kan förses med utetemperaturgivare
exakt det varvtal som krävs för tillfället. Det ger en låg ljudnivå, sparar el och uppvärmningskostnader.
Roofmaster Plus EC takfläkt STEC finns i fyra stor -lekar och täcker luftflöden upp till 1.7 m 3 /s och tryckökning upp till 750 Pa.
