*) The term step refers to the size ratio between the box's connection dimensions:
– 1 step = A difference of 1 duct dimension between the box's diffuser side connection and duct side connection, e.g. 160-125.
– 2 step = = A difference of 2 duct dimensions between the box's diffuser side connection and duct side connection, e.g. 160-100.
– 0 step = = No difference between the box's diffuser side connection and duct side connection, e.g. 160-160.
• PU: Diffuser body with perforated basket front, made of powder-coated galvanised sheet steel in white RAL standard colour. Other colours are available.
• TK: Hot-dip galvanised steel sheet, internally insulated with washable and surface-coated sound absorber made of 100% recycled, non-allergenic, hydrophobic PET plastic material.
• The diffuser is connected directly to the commissioning box, alternatively directly to circular duct.
• The socket between the diffuser and the commissioning box can be extended with a circular duct. If the extension exceeds 500 mm, the measuring hose and damper cords must be extended.
• When installing in a suspended ceiling, accessory MN can be used to extend the socket by 40 mm.
• The commissioning box is secured to a circular duct and can be installed directly after a bend.
• When installed after a T-piece, a straight section corresponding to 4 x the diameter is required.
