Replacement filter

1 set = 5 mats
Download specifications (.rtf)
Article no.:


With the aid of a self-regulating discharge flap in the occupied working area, SAM creates higher air outlet speeds by reducing the outlet cross-section. The flap fully opens at maximum air volume.


Depending on the heat requirement on site, open entrances can now be efficiently screened with minimal power consumption and low sound power levels.


In extremely adverse conditions and winds, it may be necessary to raise the air volume to maximum load and associated heat output."

How complex is filter replacement?

It is unbelievably simple: the filter can be cleaned and replaced without the need for any tools by unhinging the inlet grille and removing the fixing pin.

Can the heat output from UniLine door air curtains count partially towards the remaining heat requirement in the room?

No, it should not be added to nor be used to meet the nominal heat load in a room. The purpose of a door air curtain is primarily to effectively screen the door opening against the ingress of cold external air.
