Features & Benefits

Material Strength

A robust and durable unit with the top cowl and fan support housing in UV stabilized GRP to provide a longer life, whilst the inlet guards are zinc plated.

Aerodynamic Appeal

The inherent aerodynamic benefits of good mixed flow impeller design provide marked advantages over conventional axial and centrifugal air performance characteristics.

Motor Protection

The SMF132 is impedance protected. All other models SMF202 – SMF306 have integral thermal overload protection which prevents the motor from overheating.

Quality assurance

All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.

Blade Settings

Adjustable pitch mixed flow impellers have the blade angles factory set to meet the required duty.

Reliability

Motors have sealed for life bearings.

Mounting

SSMF units are designed to be suitable for either curb or purlin mounting and can be mounted on flat or inclined roofs with a maximum pitch angle of 35°.

Quality Impellers

Adjustable pitch mixed flow impellers are provided with blade angles set to meet the required duty. The impellers quality is reflected by natural aluminium finish spinnings and pressings and zinc plated steel hub assemblies.

Tested To The Very Latest Standards

SSMF units are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance) meaning accurate, up to date information on performance and noise data that can be relied upon.

Specification

The Skyflow SSMF range of mixed flow extract fans as manufactured by Elta Fans Ltd. 46 Third Avenue, Pensnett Trading Estate, Kingswinford, West Midlands DY6 7US, UK, Tel: +44 (0) 1384 275800 - If you need more information - Contact us.

Casing

The top cowl and fan support housing shall be manufactured from UV stabilised GRP finished in goose wing grey (BS 00-A-05). The all metal fan casing and guard provides a long lasting and robust construction. The unit shall incorporate a zinc plated frame and a bird guard on the discharge side.

Impellers

Adjustable pitch mixed flow impellers shall be provided with the blade angles set to meet the required duty. The impeller construction shall comprise of aluminium spinnings and pressings in natural finish, together with steel hub assemblies, suitably zinc plated. Assembled impellers are to be dynamically balanced to Grade G6.3.

Motors

Motors are highly efficient, lightweight induction motors with sealed for life, maintenance free ball bearings, which allows the fan to be installed at any angle.

Each motor is matched to the aerodynamic performance of the impeller. Motors are Class F insulated to EN 60034-5, weatherproofed to IP55 and all suitable for speed control. Each motor has integral thermal overload protection.

Fans are suitable for operating temperatures between -20℃ and +70℃ fixed speed and -20℃ and +50℃ when used with a speed controller.

Electrical connection to the motor shall be provided by an IP55 terminal box fitted to a 550mm long flying lead.

Quality Management

Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001: 2008. All SSMF units are to be tested to ISO 5801:1997 (airside performance) and BS 848 Part 2: 1985 (sound performance).
