For system ceiling

Square diffuser for system ceiling (T-bar diffuser)

(STE / STEP type)

<Features>
Most suitable for system ceiling. Fixed inner cone / inner pan.

1. Suitable for T-bar, system ceiling. 2. Having draft is minimized because air flow pattern is only horizontal. 3. 4 kinds of neck diameter is available according to air volume. * Adopting SED III or plate shutter (PS II) for air volume control is recommended.	(STE type)
	(STEP type)

Square diffuser for system ceiling (T-bar diffuser)

(STE2 / STEP2 type)

<Features>
T - bar diffuser having also vertical air flow pattern by pulling inner cone down.

1. Even in case the temperature difference between supply air and room air is large, good heating effect can be gained by vertical air flow. 2. Easy to change the inner cone position. 3. 2 kinds of neck diameter are available according to air volume. * Adopting SED III or plate shutter (PS II) for air volume control is recommended.	(STE2 type)
	(STEP2 type)

Square diffuser for system ceiling (T-bar diffuser)

(STEC type)

<Features>
For T-bar ceiling system, air diffuser and return air opening are often set together on the ceiling and this leads undesirable air short circuit. In such case, STEC can solve the problem as it supplies air slant downwards. (Refer to the sketch below.)

1. As air supply pattern is diagonal and slant-downwards, no chance for having draft and no air flow dead zone. 2. Contamination on the ceiling can be prevented due to slant-downwards air supply pattern. 3. Diffusing air will not hit the sprinkler or smoke sensor, if they are mounted on the same bar. (Refer to the sketch below.) * Mount outer cone and inner cone firmly even though drop-proof wire is provided as standard.

Linear diffuser for system ceiling (T-bar diffuser)

(STL type) <Features> Air supply direction changeable linear diffuser for narrow pitch T bar gap.	(STGL type) <Features> STL type made of glass wool board.
1. Air supply direction can be changed as horizontal → slant-downwards → vertical by moving the vane. 2. Low noise and low static pressure loss can be realized by the shape of the face. 3. Heat insulation finish by electrostatic implanting is also available. 4. Air volume controllable type, by vane is also available.	1. Lightweight & sound absorption effect. 2. The vane can control the air volume as well as air direction. 3. Equipped with fixing spring with T-bar. * ND-STGL type, having implanted diffusing area is also available. Consult Kuken for details.

Linear diffuser for system ceiling (T-bar diffuser)

(STAL type) <Features> Linear diffuser with equal air flow, for narrow pitch T bar gap. 1. Supply air equally and restrain uncomfortable draft. 2. Air supply direction can be changed as horizontal → slant-downwards → vertical by moving the vane. 3. The vane can control the air volume as well as air direction. 4. Restrain interference among air flows.	(STL-CF type) <Features> STL type supplying air slant-downward from left & right side. (Refer to diffusing pattern below.) 1. Prevent the draft just below the diffuser. 2. Restrain the short-circuit when return opening is located on the ceiling. * Fixed air supply direction.

Linear diffuser for system ceiling (T-bar diffuser)

(OML type) <Features> Linear diffuser with various air flow, for narrow pitch T bar gap. 1. Protean air flow pattern by split vanes. 2. Vanes can control the air volume as well as air direction, generating low noise.	(STL-2 type) <Features> STL type correspond to larger air volume. 1. Diffuse doubled air volume which normal STL can do. 2. Diffuse mixed air from both sides..
