CONSTRUCTION FEATURES
The DSP series square diffusers, equipped with a circular supply collar and a flat screen adjustable in 4 positions, are suitable for ceiling-mounted air supply and are designed for installation heights up to 4.5 meters from floor level.
The ability to set the central plate in four different positions allows for variation of the supply air deflection angle: from horizontal with a ceiling effect (for cooling) to vertical conical (for heating – recommended maximum ΔT of +8°C).
The width of the peripheral slot is adjusted by vertically moving the central plate, which is secured to the outer frame by means of appropriate pins and springs.
The DSP. series diffusers are composed of four elements: a square outer frame, a circular connection collar, an adjustable square deflection plate, and a butterfly damper on the collar (available on request).
Variants::
- DSP.: solid deflection plate
- DSP.FT: partially perforated deflection plate with variable-section circular holes
- DSP.FQ: partially perforated deflection plate with variable-section square holes
