AM 300

Airmaster presents the new AM 300.

A long list of improvements but basically the same

AM 300 is a medium size ventilation unit which is suitable for several different types of rooms such as offices, meeting rooms, restaurants, etc.

The new AM 300 is a decentralised ventilation unit of exceptional quality, offering a high level of flexibility and carefully considered, user-friendly technical details. Low energy consumption and environmental sustainability have also been in focus.

The new AM 300 is a continuation of the existing AM 300. All the best features of the existing model have been preserved: EC motors, efficient countercurrent heat exchanger, automation, to name but a few. However, the AM 300 has been updated and improved on a long list of points, so it is safe for us to say that the product takes decentralised ventilation soundly into the next phase of the concept – decentralised ventilation for comfort use.

Like all other Airmaster ventilation units, AM 300 can be controlled from a separate control panel, but it can also be controlled via Airmaster’s “Airmaster Airlinq Online” IoT platform or connected to a BMS system.

Throw lenth

The air handling unit disperses inlet air depending on the blade angle settings.
The illustrations show the dispersion pattern and throw length for the various blade angle settings at an air flow of 275 m3/h:

1. Large inlet diffuser opening, 60º blade angle.
2. Large inlet diffuser opening, 45º blade angle.
3. Large inlet diffuser opening, 30º blade angle.
4. Large inlet diffuser opening, 5º blade angle.

Changing the air flow also affects the throw length.

Facade

Full flexibility on the façade and inside the building

Use and installation of the new AM 300 are extremely flexible.

 

  • The supply and exhaust can be positioned in the back, the top or the side of the unit.
  • Ducted supply air and ducted exhaust air can be supplied.

  • A neat, uniform look can be achieved externally with the side supply and exhaust, regardless of the location of the unit.

 

Inside, it can be made to fit around windows and beams, allowing you to take the design and layout of the rooms into account.

Inside the building

The inlet grill is now always positioned at the bottom of the front of the unit. A new inlet system, where the upward inlet ensures proper air diffusion, provides draught-free ventilation. The same high quality of air distribution is achieved in the room whether the new AM 300 is installed under the ceiling or partially integrated into it. Under normal circumstances, the unit can be lowered up to 50 cm from the ceiling and continue to maintain a draught-free inlet.

The option of ducted inlet and ducted extract offered by the new AM 300 make for great flexibility when it comes to installation.

For example:

Installation To Rum

Where extract from an adjoining room is desired

Installation To Rum Ind Uds

Where both extract and supply in adjoining rooms are desired

Installation To Rum Ind

Where supply to an adjoining room is desired

Installation Langt Rum

In a long room

It is also possible to install the ventilation unit fully or partially in the ceiling. All Airmaster ventilation units can be installed above a diffuse ceiling, leaving only the base plate visible. The air is blown in above the diffuse ceiling and seeps down through it. All that is needed for this is a separate extract fixture.

Inside Under Loft

Installation with the ventilation unit under the ceiling.

Inside Partly Integrated

Installation with the ventilation unit partially integrated in the ceiling.

Ventilationsloft

Installation with a diffuse ceiling. The ventilation unit sits above the ceiling with the base plate accessible.

Smaller bushing in wall/roof – from Ø200 to Ø160

In 2019, Airmaster launched the Boomerain façade grill (patent pending), which means that the dimension of wall bushings can be reduced.

The same applies to the new AM 300. The dimension has been reduced from Ø200 to Ø160. This makes drilling the hole cheaper and the façade grill less visible from the outside.

Option of an ePM1 80% filter

The new AM 300 is more compressive than its predecessor and can be supplied with an ePM1 80% filter on supply air. ePM1 80% corresponds to the earlier F9 classification, and is, for example, suitable for use in metropolitan areas where filtration of microparticles from traffic is desirable. For use in ODA 2 climate zones. We have also made it easier to insert/remove the filter when space under the unit is limited.

Boomerain Ø160

Façade grill – Airmaster Boomerain Ø160 is set for launch Q2 2020

Classifications

Focus on low noise

With the new AM 300, we have set ourselves the challenge of meeting the particularly stringent requirements for low-frequency noise that apply to school buildings in Sweden and Norway, among other places. We have risen to the challenge and believe that the improved low-frequency noise performance is of interest to all our customers. These requirements are simply formulated in Swedish law, in that the C-weighted sound level must not exceed the A-weighted sound level by more than 20 dB, so that at 30 dB(A), a maximum of 50 dB(C) may occur.

Low energy consumption – Ecodesign class A

The new AM 300 still has the low-energy EC motors and an efficient countercurrent heat exchanger with an efficiency of approx. 85%. The unit uses very little energy to transport air and complies with energy class A, cf. Ecodesign.

Focus on airtightness and minimal leakage

Airtightness has been improved on the new AM 300 and complies with:

  • class L2, cf. EN 1886:2007 and
  • class A1, cf. EN 13141-7:2010.

 

Airtightness also applies to the newly developed shut-off dampers, which comply with class 3 for shut-off dampers, cf. EN 1751:2014.

Environmental measures

Recyclability has been in focus during the development of the new AM 300, and several measures have been taken in connection with the selection of components.

  • As many components as possible can be separated and reused at the end of the unit’s life.
  • New wire bushings make it easier to remove electrical components from the unit.
  • New production methods have been introduced which have, for example, reduced the use of adhesives by up to 90%.
  • The insulation is free of pigments and made from recycled foam materials of 100% polyurethane granulate, which can be recycled.

Adjustable inlet air system

The new AM 300 is fitted with a manual version of Airmaster’s adaptive inlet air system. The diffusion and throw of the inlet can be set to adjust the unit to the conditions.

Furthermore can be mentioned:

  • A service switch can be supplied as an option, so that units stop when the base plate is opened.
  • Base plate with 4-link hinge, which makes for the safe, precise positioning of the base plate in relation to the cabinet. It also allows space for a door or window frame behind the base plate.
  • There is space for 40 mm condensation insulation and 13 mm plasterboard around pipes for supply air and extract air.
  • Wiring and condensation drain hoses can be routed to either side of the unit.

AM 300, polar edition and enthalpy heat exchanger

Airmaster is experiencing increasing demand for geographical regions where it can get extremely cold, with dimensioned outdoor temperatures down to -35°C. The new AM 300 is therefore being launched with two new initiatives.

  • A “polar edition” can be supplied with an extra-large pre-heating element of 2500 W and operating parameters adapted to it.
  • Instead of the normal heat exchanger, the AM 300 will be available from autumn 2020 with an enthalpy heat exchanger, which returns the moisture from the exhausted air. This solution is particularly suitable for use in cold areas, where it is desirable to retain the moisture inside the building. Further information to follow.

AM 300 generation 2

AM 300 generation 2 is being phased out but will live on in the new AM 300, which is described above.

AM 300, which has been around since 2007, has sold extensively throughout most of Europe. Some 12,000 AM 300 units have been supplied over the years. The new AM 300 must therefore continue the success story, and it is with no small amount of pride that we have introduced a new generation of AM 300. The new AM 300 is also the first of Airmaster’s new model range to be launched in the coming years.

If you wish to connect a cooling module, an AM 300 generation 2 is still, however, the one to use. With the AM 300 H (horizontal) model, it is possible to connect the inverter-controlled CC 300 cooling module.
