Ducting & Air Distribution
Ducting and air-distribution equipment carries conditioned or extracted air between fans, air-handling units and the spaces they serve, and controls how that air is delivered. The category covers rigid and flexible ductwork plus the terminal and control devices — grilles, diffusers, dampers and plenums — that balance airflow (m3/h or CFM) while keeping pressure drop (Pa) and leakage within design limits.
The family includes rectangular and circular sheet-metal ducting, spiral and oval duct, flexible and insulated duct, and air-distribution terminals: supply and return grilles, ceiling and swirl diffusers, linear slot diffusers, volume-control and fire/smoke dampers, and plenum boxes. Ductwork is commonly fabricated and classified to EN 1507 (rectangular) and EN 12237 (circular) for strength and air-tightness, with leakage classes (e.g. ATC/Class A–D) specified per project; fire dampers are typically tested to EN 1366-2 and classified under EN 13501. Fittings and finishes are selected for the air condition and corrosion environment.
Construction spans galvanised steel, aluminium, stainless steel and coated or PVC-faced materials, with insulation, gasketed or welded seams, and powder-coated or anodised terminals. Air-tightness, fire rating, acoustic lining and corrosion protection are matched to the application.
Himalay's verified manufacturer partners supply ducting and air-distribution equipment with test reports and CoC, CE under the applicable directives (CPR for fire dampers, Machinery/relevant directives for powered devices), RoHS/REACH, and SABER (Saudi Arabia) coordinated as part of the standard order flow; air-tightness testing, fire-damper certification or factory acceptance testing arranged where specified.
