Tagventilator BSR

Description

The high pressure industrial sickle roof fans have been developed around a new advanced, aerodynamically shaped sickle blade, for high efficiency, maximum performance, reliability and excellent speed controllability.

All cowl and roof mounting plates are moulded from specially formulated polymeric materials, which are high impact resistant and provide a rigid profile against strong winds and resistant to UV light. Standard Colour BS10A07. Alternative B.S. colours available on request, with the Cowl and Base manufactured from fibreglass.

Suitable for flat or inclined roofs (max. angle 30°). Sickle Roof Fans are designed for either kerb or purlin box mounting. All sizes are fitted with inlet wire guards, giving protection to BS848 part 5. Outlet bird guards are available as optional accessories.

The Sabre range is available in nine models with extract performances ranging from 0.192m³/s up to 3.274m³/s (619m³/h to 11786m³/h), with pressure characteristics of up 200Pa.

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. Rotors are dynamically balanced to ISO 1940. 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 710, 6 & 8 pole motors are only suitable for operating temperatures of up to 40°C.

Terminal Box

An IP65 isolator is supplied with all models with 20mm and PGII entry offering protection against dust and water jets from any angle.

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 710 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.
