Thefaniswell-suitedforspeedcontrolandthereforeconformstomarketdemandsonadjustingtheairflowtomeetpresentneeds.

Advantages of the Sky WingThe Wing fan impeller offers quiet and energy-saving performance.

Its high discharge capacity allows for large duct systems and connected functional sections.

Enables demand-controlled ventilation by con-trolling the fan speed, keeping the air pressure constant and compensating variations in outdoor air temperature.

Service-friendly – the fan can be raised on hinges and has a removable upper section as well as removable side panels.

Measurement tappings for pressure/airflow read-ings enable correct commissioning and periodic performance checks.

Its modest design fits well in a variety of environ-ments.

Operates quietly and saves on energy

Technical Description

Description of Test with Combustion-gas Fan

Test of an LTCW-1-060-1-4-1 Power roof ventilator, in the combustion-gas version, Order no. 204 825

The test was conducted in the Emergency (SOS) Service container facilities at the Flampunkten (Flash-point) Testing Ground. The fan was mounted on a container that is connected to a fire caisson made of steel surrounded by cement stone. The fan was wired to a three-phase power supply and was started up. Pallets were burned inside the caisson and a type TM-916 temperature gauge was used for continuously measuring the temperature.The fan operated throughout the heating period (see Appendix 1). When the temperature reached 300 degrees Celsius, test events were timed until 120 minutes had elapsed. Throughout the period, we sought to obtain smallest possible differences.(See Appendix 2)

When 120 minutes had elapsed, Test no. 2 started and this involved keeping the temperature at about 400 degrees Celsius for 60 minutes.Maintaining a constant temperature of 400 degrees proved difficult since we obtained substantial differences in temperature.It is quite clear to us that the fan has passed the test, among other factors, because the temperature was up to 475 degrees at the most and because the fan had managed to operate for 120 minutes impelling 300-degree gas during the previous test.(See Appendix 3)In our opinion, the fan managed to operate for 180 minutes impelling 300-degree-Celsius gas during the first test since the temperature was considerably higher during the last 60 minutes.
