Slimline fan gives clear vision for accurate tunneling

The Problem

On the 12.3 km Vienna Lainzer rail tunnel project, for the Austrian railway company OeBB, Consulting Messtechnik (Comet) is employing a Global Navigation Satellite Positioning System-based measuring device to monitor excavation work and check for any deformation.  In order to ensure maximum efficiency and accuracy at all times, Comet needed to find a easy method of keeping it’s equipment’s lenses free of dirt and dust.

The Solution

An ACI VLB5/3 Slimline fan supplied by the company’s German distributor Carl von Gehlen.  This unit is based upon an inside-out motor with the rotor on the outside driving a forward bladed impeller. This blower with its forward curved blades is a compact efficient unit, delivering high air volumes at high pressure, the precise characteristics required for this application.

The Outcome

“It is essential that we keep the lenses of our OBM measuring systems clean at all times.  This has been achieved successfully thanks to the performance and reliability of the ACI blowers in a very difficult, dusty environment.” Boris Schukoff, Comet.
