RS series rectangular duct fan for supply and extract air in industrial and commercial HVAC installations. Designed for high airflow applications with options for acoustic and thermal insulation.
Available insulated variant (RSI) with 50 mm rockwool acoustic and thermal insulation.
Offered with AC or high-efficiency EC external-rotor motors suitable for 50 Hz and 60 Hz operation.
Service-friendly design with swing-out service lid and installation possible in any mounting position.
Main features
Casing: galvanised sheet steel, corrosion class C3. Insulated RSI variant includes 50 mm acoustic/thermal insulation. Service cover carries the fan unit for easy removal and cleaning. External terminal box, protection class IP54.
Impeller: single-inlet radial impeller with backward-curved blades, fiberglass-reinforced composite; dynamically balanced (VDI 2060, G 6.3) and matched to external-rotor motors.
Motors: AC or EC external-rotor types. EC variants include integrated electronic motor protection, locked-rotor protection and soft-start; many EC variants provide potentiometer (0–10 V) and Modbus/alarm signals. AC motors may have thermal contacts (TK) or require external protection. Control options include multi-step or stepless regulators and frequency converters (accessories).
Installation: rectangular inlet/outlet flanges (standard PG20). Use flexible connections to avoid vibration transfer to ductwork. Suitable for indoor installation and for elevated operating temperatures up to specified limits.
