NSAL(N) Aluminum slot diffusers

Transcription

1 Aluminum slot diffusers NSAL(N) Atesty igieniczne: K/B//0/007 The NSAL(N) type diffusers are ceiling diffusers with longitudinal air supply slot with individually adjusted blades mounted inside. The NSAL(N) type diffusers are intended for air supply into the spaces with height of,6 6,0 m. There is also possibility of installing them in vertical barriers. -slot diffuser NSAL -slot diffuser NSALN SMAY LLC / 9 Ciep³ownicza St. / -87 Cracow / Poland tel / fax / info@smay.eu

2 Intended use NSAL diffusers (N) are intended for systems with constant and variable air flow. The high degree of air stream induction makes the diffusers NSAL (N) efficient in either cooling or heating mode. The recommended temperature difference is ± 0 [K]. Individually adjustable blades allow for the appropriate directing of the air stream (the desired air flow profile). NSAL diffusers (N) may also operate as the air exhaust. Material and finish NSAL(N) series diffusers are available in two versions: The standard diffusers NSAL consist of an aluminum frame with individually adjustable blades inside. It can contain from to 6 air supply slots. In standard, diffusers are equipped with circular blades. In case of white or gray calor (including the anodized finish), the blades are made of plastic. In case of other colors, blades are made of aluminium. On special request it is possible to manufacture white and gray blades from aluminium. Coating the diffuser on RAL color is available on special request after the consultation with sales representative. In special version, the diffusers NSAL-N are equipped with adjustable blades, which allow the change of degree of covering the air supply slot of the diffuser or directing of the air flow. Both the casing and the diffuser blades are made of aluminum. On special request, the diffuser body may be powder coated in any RAL color. a) Standard version NSAL b) Special version NSAL-N Recommended installation methods NSAL diffusers (N) can be mounted directly to the ceiling in case of the using above-ceiling air supply space or using plenum boxes. Dedicated plenum boxes may be equipped with control damper on the air intake connector. Plenum boxes may optionally be insulated, by lining the inside with polyurethane foam with thickness of 0 mm. a) Installation directly to the barrier with use of mounting bracket Draw.

Diffusers can be installed separately or linearly. Diffusers which are installed separately have a frame with width of 0 mm on each side. Frame size of NSAL(N) diffuser intended for linear installation was reduced from side of diffuser joint in order to keep the attractive appearance of the system.

4 Air supply profiles The design of the diffuser enables the vertical and horizontal directing of the supply air stream. The required effect is achieved by changing the angle of the blades.
