Introduction
A range of extract units designed to economically provide positive powered extraction to remove warm, stale or contaminated air.
Each available in six sizes with 2 pole , 4 pole, 6 pole or 8 pole models.
Selections can be made after comparing the noise levels, electrical loadings and performance data on specification sheets available at the top of this page.
The units incorporate the highest quality motors with excellent speed regulation characteristics and thermal motor protection facilities available.Shutters
Lightweight grp backdraught shutters are supplied as standard. Airflow operated, they open when the fan is running and close when the unit is switched off, therefore, ensuring minimal heat loss through the unit.
Upward discharge units also have external guards.
They are of the asynchronous induction type, compliant with all relevant LVD, EMC, ROHS, Energy Usage and Machinery UE directives as weel as IEC60034 & IEC60072 standards.
Bearings are 'sealed for life' type. Class F insulation and construction to IP55 is standard.
All motors are fitted with a thermistor to enable overheat protection if required.Electrical Supply
Units are suitable for 380-415V, 3ph, 50Hz electrical supply.
Also, motors can be supplied suitable for a 220-240V, 3ph, 50Hz (for suitable inverter drive output).
Finally, 230V single phase motors can be built on special request.

Introduction
A range of extract units designed to economically provide positive powered extraction to remove warm, stale or contaminated air.
Application
Suited to wide range of applications calling for controllable powered extraction under variable weather conditions.Description
Roof mounted for curb and pitched roof mounting, the range provides both Low Silhouette & Upward Discharge designs:-
Each available in six sizes with 2 pole , 4 pole, 6 pole or 8 pole models.
Selections can be made after comparing the noise levels, electrical loadings and performance data on specification sheets available at the top of this page.
The units incorporate the highest quality motors with excellent speed regulation characteristics and thermal motor protection facilities available.
Sizes
Sizes range from 300mm through to 800mm with duties up to 7.28m³/s.Materials
Base and cowl assemblies are manufactured from glass fibre reinforced polyester resin, with fire retardant characteristics in accordance with BS476 Class 2, Part 7.Colour
Standard colour is to BS4800 is 00-A-05 (grey). Other colours are available.Shutters
Lightweight grp backdraught shutters are supplied as standard. Airflow operated, they open when the fan is running and close when the unit is switched off, therefore, ensuring minimal heat loss through the unit.
Guards
All units are fitted with hot dip galvanised steel internally fitted guards as standard.Upward discharge units also have external guards.
Impellers
Constructed from injection moulded, quality thermoplastic with glass fibre filler, all impellers are dynamically balanced as per ISO 1940.Motors
