Decsription

Type: Commercial quality cooling and destratification fans

Application: Commercial/Industrial

Control options: Range of optional controllers available

Originally designed to provide a cool flow of air during warm periods, Xpelair SweepFans are a popular choice for winter applications too, where their use as heat destratification units can reduce heating costs. These commercial quality products are designed for use in public buildings, shops, theme pubs, restaurants, village halls, churches, hospitals, schools, farm buildings, factories, warehouses and other commercial buildings.

SweepFans are designed for worldwide use, including hot and humid conditions. The units are rated for continuous operation in commercial applications at temperatures up to 40ºC and are suitable for upwards or downwards airflow. The triple bladed units are available in four sizes with swept diameters from 900 to 1500mm.
Fan blades are steel and are supplied in matched sets. SweepFans are supplied with a choice of two lengths of suspension rod giving overall drops of 375 or 750mm.

In summer the atmosphere can become stifling hot. SweepFans can provide immediate relief by quietly delivering a continuous cooling breeze over a wide area. To maximise the benefit it is good practice to introduce fresh air into the area.

In winter stratification will naturally occur in a room as hot air rises to ceiling level (or the apex of the roof) and cooler air sinks to ground level. Xpelair SweepFans will effectively destratify the hot air which gathers at ceiling height by pushing it downwards to mix with cooler air nearer to ground level, thus providing a more uniform temperature profile from floor to ceiling. This results in reduced heating costs as all the hot air does not gather at ceiling height, and thermal losses are reduced. The units should be set for downward airflow at low speed for optimum effect.

The optional Xpelair ThermoMiser sensor control system can automatically compare high and low level temperatures and ensure that the fans are operated to maximise energy efficiency. The controller should be sited where the ambient is less than 35ºC, with the two sensors fitted at high and low level and connected using the cables supplied. In summer the control knob can be used to manually override the sensors. For no-frills speed control the Xpelair SweepFan controllers are available for the control of a single fan or groups of up to 6 fans.

All SweepFans have integral anti-vibration bobbins and a continuously rated capacitor start and run external rotor motor. The motor incorporates two sets of caged ball bearings for extra long life.
