Air Quality Sensor SQA - Electrical  

    

Automatically switches the fan on when the quality of the ambient air deteriorates below an acceptable level due to fumes, odours, tobacco, smoke, dampness etc.

The SQA is an adjustable Run-On-Timer facility, which enables the fan to operate for a preselected time period after the air quality sensor has switched off. 

Important: This sensor MUST NOT be used to detect combustible gasses or fires and in connection with any safety alarm systems.

Inverters - Electrical

    
Supply Motor Current Rating Enclosure Rating
Single-phase Three-phase to 7A IP20
Three-phase Three-phase to 340A IP20

*Only for motorsthat are 45V star/240V delta, the motors are then connected in delta

Inverters can be used to control conventional motors provided they have adequate cooling.   

The control of conventional motors is more effectively done using frequency inverters which vary the motor speed by varying the frequency of the electrical supply. Recent developments in power electronics have resulted in drive efficiencies as high as 98% being achieved with additional benefits of reduced noise levels, reduced harmonic distortion to supply, increased ratings and improved reliability.

The units for single-phase supply can have a forward / reverse / stop / reset switch and LED status indicator. Some three-phase controllers, in addition to the above, can have a digital speed meter incorporated.

These speed controllers normally require the electrical cables to be shielded along their entire length to comply with regulations. Inform our Sales Engineers if an Inverter is going to be used so it can be ensured that all fan internal wiring is shielded to meet EMC requirements.

Additional care must be taken if the inverter unit is mounted remotely from the fan being controlled.

ZN62 - Electrical

    
The ZN62 run-on timer is designed to permit the supply of electricity to motors or lights so they can continue to operate for 6 minutes after the power is switched off. They also provide a 2 minute start delay.

TDE

The Multiflow TDE 500 to 710 range consist of fully cased, cylindrical models with circular mounting flanges at both ends and a wired terminal box.

RVF

The Mini Centrifugal Roof Fan series are the new type roof extract units available in 2 sizes and suitable for vertical and horizontal installation. The low noise external motor and high efficient backward bladed impeller meets the requirement of efficient ventilation in residential, commercial and light industrial applications.

Future 150

The Decor Series can be wall or ceiling mounted and is designed to exhaust stale and moist air from bathrooms, toilets, laundries etc. They are also suitable for ventilating all types of small or closed areas.

TD Silent

The Silent Series is a low profile mixed-flow in-line fan that produces low noise when in operation. It does this through a specifically designed perforated internal skin that directs sound waves produced inside the fan to a layer of sound absorbent material.

NEW!! TD-EVO

The low-profile TD-EVO 250 and 315 in-line mixed-flow fans for circular ducts have a unique design where the support bracket allows the motor and impeller assembly to be fitted or removed without dismantling the adjacent ducting.
