This innovative Air curtain installation with its compact, cylindrical shape has been specially developed for visible mounting, upright or hanging. Its preferred upright configuration offers the advantage of a heated air current of consistent velocity directly at floor level. Its pleasing design in conjunction with low-maintenance operation and invisible power connections (for upright versions) is a plus factor for architects, planners, building contractors and operators. The optionally galvanised RAL coloured powder coated covering or stainless steel version all blend in well with existing doors and doorways. This Air curtain can be used at entrance and exit doors or at draught excluders and thermic mixing in summer and winter.
