BOR-S-100-SW Supply air valve, RAL9010

BOR-S has been especially developed for providing a draught-free and low acoustic noise air supply from the rear walls of offices, hotel and residential rooms etc. The flow pattern prevents the air stream from falling into the occupied zone before it has reached an acceptable temperature. Max. temperature difference ΔT 10K is permissible.

BOR-S is also suitable for VAV systems, as the distribution pattern is maintained across the entire flow area. The product is equipped for air flow adjustment and commissioning measurement.

Design

The body of BOR-S is manufactured from galvanized steel with a convex, rectangular shaped front plate with perforation. The front plate is finished in the standard white powder-coating (RAL 9010, Gloss 30). Inside the body a flat adjustable blind is attached.

Technical details

The diffuser is equipped by an adjustable blind that changes the effective air flow aperture and so tunes the air flow volume. The mechanism is movable from outside by two miniature ears sliding in grooves on the sidewalls of the product. The movement has 8 fixed positions along the path defined by the notches in the groove. For adjustment only these positions provide desired noise parameters. The intermediate positions shall be avoided. The tables 1 and 2 show the k-factors of the product in each of the 8 fixed positions. Using the corresponding K-factor for the chosen adjustment along with the ΔP measured on the measurement pin (sidewall) of the product provides data for an easy actual flow calculation at commissioning.

After commissioning the measurement pin shall be closed. For aesthetic reasons it can be replaced by the smooth plug which is packed in the product box.
