Motors meet smoke extraction standards
WEG is meeting the demands of EN12101-3 with its new line of smoke extraction motors.
Poor evacuation procedures in difficult to reach locations, inadequate disaster planning and human error have all been major factors in a number of major accidents that have occurred in Europe over the last few years The result of these accidents has been the loss of hundreds of lives, due mainly to the lack of adequate systems to protect people from the effects of fire, particularly smoke inhalation and heat

Smoke extraction motors aid safe escape
The Flakt Woods Group is using smoke extraction and fan and exhaust motors as part of a prestigious contract to supply ventilation fans on the Al Jamarat road and passenger bridge.
The introduction of the new European Standard, EN12101-3, (Smoke and heat control systems - Part 3: Specification for powered smoke and heat exhaust ventilators) is designed to address this problem.
Approved by the European Community on 9th June 2001, the standard specifies requirements and provides methods to test smoke and heat exhaust ventilator systems and their corresponding drive motors.
Based on the new standard EN12101-3, the main goals of smoke and heat ventilation systems generally are to: keep escape and access routes free from smoke; facilitate firefighting operations by creating a smoke free layer; delay and /or prevent flashover and thus full development of the fire; protect equipment and furnishings; reduce thermal effects on structural components by preventing the build-up of roof temperatures; and reduce damage caused by thermal decomposition products and hot gases.

WEG is meeting the demands of EN12101-3 with its new line of smoke extraction motors.
These motors are designed to withstand temperatures of 400C for 2h, and have achieved successful tests results according to the applicable standard.
In addition to this certified line, WEG has also begun testing of another motor range to achieve further performance levels established by the standard: operation at 200C for 2h and 300C for 1h.
The construction and performance of WEG's new smoke extraction motors mean that they can be applied on ventilation systems in buildings or construction works, shopping malls, industrial buildings and warehouses, enclosed car parks, stairways, tunnels and theatres.
There are three classifications: F400 (withstand 400C for 120min); F300 (withstand 300C for 60min); and F200 (withstand 200C for 120min).
Some of the main features of the range include: frame sizes from 80 to 355 (and above - self certified); construction is TEFC or TEAO (foot mounted; flange mounted; pad mounted); single- or two-speed operation; special insulation; the terminal block, grease and leads are all designed for high temperature operation; and aluminium paint is used.
