Slot Diffusers Type VSD35 Varyset Get latest price

• Nominal length from 900 to 1500 mm, 1 or 4 slots
• Volume flow rate range 8 – 90 (l/s)/m or 29 – 324 (m³/h)/m
• Diffuser face made of extruded aluminium sections
• For variable volume flows
• Excellent room ventilation even with small volume flow rates due to self-powered Varyset flap
• Suitable for continuous linear arrangement
• High induction results in a rapid reduction of the temperature difference and airflow velocity
• Individually adjustable air control elements to meet individual local requirements

• Exposed diffuser face available in RAL CLASSIC colours
• Diffuser face with extended border
• End plates, end angles

Application

• Type VSD35 Varyset slot diffusers are used as supply air diffusers in comfort zones
• They blend in inconspicuously with continuous grid ceilings and plasterboard ceilings
• Excellent room ventilation even with minimum volume flow rates (V_min)
• Air discharge is one-way or alternating horizontal, or alternating angled; turbulent flow (mixed flow ventilation)
• High induction results in a rapid reduction of the temperature difference and airflow velocity
• For variable volume flows
• For supply air to room air temperature differences from –10 to +10 K
• For room heights up to 4 m (lower edge of suspended ceiling)
• For suspended ceilings; suitable for restricted ceiling voids due to the low overall height of the plenum box
• Suitable for continuous linear arrangement

Special characteristics

• Individually adjustable air control elements to meet individual local requirements
• Excellent room ventilation even with minimum volume flow rates (V_min)
• High induction results in a rapid reduction of the temperature difference and airflow velocity
• Diffuser face has been optimised for maximum volume flow rate at low sound power levels
• Suitable for continuous linear arrangement

Nominal sizes

• L_N: 900, 1050, 1200, 1350, 1500 mm
• Diffuser face available in intermediate sizes from 901 to 2550 mm, in increments of 1 mm
