The range consists of 2 models a 1.5 meter and a 2 meter long unit or module .

The definition of Ambient Air with regards to industrial and commercial air curtains is in reality ambient temperature  – In a air curtain context, ambient temperature is the air temperature of any environment where air curtains and related equipment are located. The adjective ambient means “relating to the immediate surroundings”- Thus these are not heated air curtains – they just use the ambient air withing the building to cause a high pressure air curtain to prevent the interior of the building from the ingress of air from the outside, and thus losses of heat. There are additional benefits that these air curtain provides in protection against pollution, dust, fumes, undesirable odours and insects
