Tagventilator RSV

Description

High pressure Vertical Discharge Sickle roof fans have been developed around a new advanced, aerodynamically shaped sickle blade, for high efficiency, maximum performance, reliability and excellent speed controllability, ideal for ducted applications.

Cowl and roof mounting plates are moulded from glass fibre reinforced polyester, which are high impact resistant and provide a rigid profile against strong winds and resistant to UV light. Standard Colour BS00A05, alternative B.S. colours available on request.

A backdraught shutter kit is fitted as standard to all RSV fans, ensuring full weather protection during shut down periods.

Suitable for flat or inclined roofs (max. angle 30°). Vertical Discharge Sickle Roof Fans are designed for either kerb or purlin box mounting. All sizes are fitted with inlet wire guards, giving protection to BS 848 part 5.

The RSV range is available in seven models with extract performances ranging from 0.382m³/s up to 3.429m³/s (1,375m³/h to 12,344m³/h), with pressure characteristics of up 150Pa.

Motor/impellers

The motors and impellers are factory matched, statically and dynamically balanced to VDI 2060 Quality Class G.6.3.

The external rotor motors are specifically designed and styled for this range of fan. Ball bearings are greased for life. All motors are protected to IP54, against dust and moisture complying with BS EN 60529. They have ribbed aluminium body castings for efficient cooling with Motor insulation to Class 'F' (from -40°C to + 70°C). Speed controlled sizes 450 to 630, 6 pole motors are only suitable for operating temperatures of up to 40°C.

Electrical

The Sabre range is available for either single phase 220-240V 50 Hz capacitor start and run or three phase 380-415V 50Hz. Motors are fitted with Standard Thermal Overload Protection (S.T.O.P.) which should be wired into all controller circuits and into starter contactors to prevent motor damage due to overloading / overheating. Three phase 380-415V 50Hz units, from 450 to 630 diameter are fitted as standard with 2 speed Delta/Star connection motors. Most units are suitable for speed control by either electronic, voltage reduction or frequency inverters where permissible.

Terminal Box

An IP54 terminal box is supplied with all models with 20mm and PGII entry offering protection against dust water jets from any angle.
