AIR DISTRIBUTION PRODUCTSFansSystemair has a wide range of fans for use in various applications from small office premises to larger industrial applications. Common to all items in the range is that components have been developed to satisfy stringent demands for low energy consumption.

The fans have all undergone extensive test-ing, both in the laboratory and out in the field, in order to comply with current and future demands for low energy consump-tion. All products are also manufactured to comply with environmental requirements.

Roof fansEffective exhaust air system for horizontal or vertical air discharge

Explosion proof fans & smoke extract fansfans for explosion hazardous areas & smoke and heat extract

Axial fansEffective supply and exhaust system for industrial buildings applications

Circular & rectangular fansWide range of use for all kinds of installa-tions

FIRE AND SMOKE DAMPERSSystemair produces fans, dampers and control equipment for dual use, i.e. for nor-mal operation and certified for use during normal operation and in the event of a fire.

Fire & smoke dampersDampers that reduce the spread of smoke and fire.

6A good indoor climate is vitalWe often take natural resources such as fresh air for granted. We must however remain frugal with this essential resource and mindful of maintaining a responsi-ble balance between the designing of good ventilation systems and considering energy consumption and well thought out material usage and production meth-ods. Systemair has recognized this need and has developed the "Green Ventila-tion" registered trade mark for ventilation labelling these products.

One of Europe's most modern development centres

A room that is so quiet that the only thing youll hear is your heartbeat.

The development centre in Skinnskatte-berg, recently accredited by AMCA, signifies an investment of EUR 700,000 and is fitted with measurement and testing equipment, making it one of the most modern facilities of its kind in Europe.

The quiet room is one of the test stations or a reverberation chamber, producing a background sound of less than 10 dBA. When measuring supply air terminals, a green laser is used to show how the air is expelled from wall-mounted or ceiling-mounted devices. There is also a climate chamber that cools the air to -20C, which means we can use it all year round to develop our recovery units. In addition to the test centre in Skinnskatteberg, there are also test facilities in Germany and Denmark where we can measure air volumes of more than 400 000 m3/h.

Heat recoveryIn areas with a relatively low average annual temperature, ventilation systems employ effective heat recovery that returns energy from extract air to the supply air. A good rotating heat exchanger can recover up to 90% of the energy present.

Energy-efficient fansToday, there is a new generation of fan mo-tors that contribute to a dramatic reduction in energy consumption, as much as 50% in some cases. The new EC motors are better suited to speed control functions, which is where considerable energy savings can be made. Further benefits are of quieter operation as well as extended product life.

to ensure that our products maintain a high standard and are approved by various bodies. For units, this may mean Eurovent certification or other local certification for the country in question. To achieve this, you need resources and expertise. Within the Group, you will find, among other things, one of Europes most modern development centres, which is AMCA-certified.

PressureThe design of the duct system and the unit has an impact on required system pressure. There are often tens, sometimes hundreds, of Pascals to be saved here.

Cool recoveryIn warmer parts of the world, energy sav-ings may be possible by drawing cool night-time supply air into premises, thus cooling the building structure.

Quality-certified productsHow can you choose the right solution and product when there are so many alterna-tives? Nowadays, most major suppliers are ISO-certified and have CE-marked products, but is that enough? At Systemair we are going one step further and working hard

7Product catalogue and specification dataMore detailed technical information, suf-ficient to carry out complete planning, is available in separate catalogues and speci-fication data. These describe all incorpo-rated functions, available accessories, and additional technical data.

Selection toolsWe have developed this overview to make it easier for you to get an idea of which product best suits your specific needs. More detailed analysis or planning usually requires additional information, which is where the following tools come in.

BHCReturn air self regulating motorized valvewith presence and humidity sensor

FunctionBHC 100 is a motorized damper with integrated motion (PIR) and humidity sensor for bathroom installations. The extract units may be installed either on the wall (in a vertical or horizontal posi-tion), or the ceiling. The humidity and the motion sensors work independently of each other. The damper opens whenever motion is indicated and closes 25 min after the last indication. The hu-midity sensor controls the fully modulating damper from RH 30% to 75%. The movement sensor is dependent on a power supply and the BHC uses either a 9V battery or 12V AC. The humidity sensors will open the damper regardless of a power supply.

Spigot Versions100 mm and 125 mm (with adapter).80 mm (with special sleeve 80 mm). note: the BPD is delivered with adapter 100 mm. The BPD dampers are especially useful in constant pressure systems for example block of flats.

Accessories100/125 inlet adapter and 12/9 v transformer.

ALReturn air self regulating valve

DesignFunctionIntended to equip the facilities housing MEV, housing and local service, the range of the AL extraction air valves self meets the regulatory requirements while combining aesthetics and technology. Design fluid grid in several colors, reliability mechanical, proven functionality, per-formance ventilation and noise are the major assets of all AL air valves series. The AL air valves meets the residential requirements of the NF MEV. Single or double speed, both models perfectly consistent allow a uniform architectural treatment between kitchen, bathroom and WC.

ModelProduced in white polystyrene(standard), the AL air valve, installed in WC room and baths, pro-vides a flow of extraction determined.

OperationThe regulator consists of a rigid component and ensures a determined air flow of extraction within a range of pressure between 50 and 160 Pascals.

AL is available in the following air flow: 15, 30, 45, 60, 75, 90, 120 and 150 m3/h

MaintenanceTo maintain maximum efficiency, it is necessary to conduct a periodic cleaning:

Remove the grille (4) and regulator (3) the body of the valve (removed from the sleeve if necessary).

The sleeve (1) shall not be detached from the duct. Clean all either in the upper part of a dishwasher, either manually with soap and water, nothing

disassemble the regulator. Walk up the valve.

InstallationThe AL is installed in vertical walls by simple fitting onto a 125 sleeve fixed on the aeration duct. The lip seal ensures that the sleeve is securely fixed and watertight. Possible fitting with 99, 116, 150 or 160 mm. When ceiling mounted, an adapted sleeve can be used (125 , 3-claw plasterboard sleeve, or 125 plastic sleeve for penetrating slabs for use with the 125 sleeve).

AEReturn air self regulating motorized valve

FunctionIntended to equip the facilities housing MEV, housing and local service, the range of the AE extraction air valves self meets the regulatory requirements while combining aesthetics and technology. Reliability mechanical, proven functionality, performance ventilation and noise are the major assets of all AE air valves series. The AE air valves meets the habitat requirements of the NF MEV. Single or double speed, both models perfectly consistent allow a uniform architec-tural treatment between kitchen, bathroom and WC.

ModelProduced in white polystyrene(standard), the AE air valve, installed in WC room and baths, pro-vides a flow of extraction determined.

OperationThe regulator consists of a rigid component and ensures a determined air flow of extraction within a range of pressure between 50 and 160 Pascals.

PrincipalsThe extract is always on tension thanks to a connection normally switched off.An impulse on the switch creates a power cut which opens the extract to its maximumflow (opening time: around 40 seconds).The 230 V supply of the extract is provided by two wires (2 x 1.5 mm) to be connected,going out by the back of the support plate (see drawing). This must have a protec-tiondevice clearly identified on the electric board - class II electric appliance -.After taking out the casing vent (2), unscrew the box (5). The wires go through a cableat the back of the plate and linked to the connection box.The support-plate of the extract must be screwed on the wall.On the first stand-by mode, the AE valve will normally extract the maximum air-flow.

WiringBefore any operation on the support plate (3), the tension must be switched off (the time-switch being constantly on stand-by mode) The tension is made through a push button specially dedi-cated to this specification.

MaintenanceThe Extract AE must be periodically cleaned (at least twice a year) in order to keep their entire efficiency. Cleaning procedure : Remove the casing vent (2) of the plate (3) and remove the flap (4). The plate (3) linked to the duct must not be touched. The elements on it do not need any cleaning. Clean the casing vent (2), the grill (1) and the control module (4)with soapy water then rince. Fix back the control momule (4) Fix back the casing part (2) on the plate (3)

Ceiling mountingCeiling mounting, the unit can be fixed on the ceiling using a three-claw plasterboard sleeve or a 125 plastic sleeve for penetrating slabs. A ceiling mounting needs the using of a return angle guide for the concerned models.

This safes money and time because its easier to clean the filter of the grille instead the whole duct section and the AHU filter. The filter can be checked in a very convenient way by opening the grille and changing the filter if necessary. Because of the inclined deflectors its not possible to see through the grille.

DescriptionNOVA-F is rectangular aluminium grille with fixed deflectors and galvanized steel box for filter. It can be used in commercial and industrial premises. The grille is intended for filtering the return air and can be build into wall or ceiling. NOVA-F is supplied with hinges and knob as a standard.

DesignNOVA-F grille is manufactured from natural anodized aluminium profiles white painted to RAL 9010. The box is from galvanized steel equipped with mesh screen. Inside the box is an area for filter. Standard supplied filter is a G3 class filter, manufactured from white coloured polyester, with thickness of 12 15 mm. Temperature resistance of the filter is up to 100C with middle seclusiveness (Am) of 92,5%..

MountingThe NOVA-F grille is mounted directly into a duct or wall with screws via holes in the steel box. The grille is then closed by the hinges and securely closed with the knob.

Sinus-BRNozzle diffuser with rear entry plenum

FunctionSinus-B series of wall-mounted nozzle diffusers are built to achieve very high induction combined with changeable air distribution pat-terns. Sinus-B consists of a front plate with graded perforation above a number of nozzles (size 35 mm) and a plenum box with an adjustment damper. The plenum box is fitted with a powder coated neck flange facilitating mounting and taking up tolerances from the recess and makes a nice fit with the wall. The combination of nozzles and perfora-tion achieves outstanding induction of room air. Maximum temperature difference for cooled air T 14 K.

MountingA recess must be made in the wall in accordance with the dimension table and drawing. The plenum box is placed in the recess and pushed inwards till it stops against the plenumboxs neck flange. From the backside of diffuser bend the metal fixing bands to each side and fix to back side of wall with screws. The front plate is fitted into the plenum box by first fitting the top hook-plate into its correspondent on the plenum box and then bending the bottom edge smoothly inwards and fitting the bottom hook-plate with the plenums bottom. Gently slide the front plate downwards till it stops.
