Beckair Clustajets suit hazardous areas

The Beckair Clustajet Ventilator range from Secomak has no rotating fan blades or motors, is flameproof and virtually maintenance-free.

The compressed-air-operated fan can be used for blowing and extraction applications via standard-size flexible hoses.

The Clustajets use multiples of Beck Ringjet Air Amplifiers (themselves bladeless and motorless fans) fed from a common air manifold.

The whole unit is constructed in a robust steel casing and the design is based on space rocket launch vehicle principles.

For a given airflow, the Beckair Clustajet is lighter in weight and smaller than an equivalent explosion-proof electric fan, as well as producing less noise.

The Clustajet can be used in hazardous areas, such as ventilating sewers, tunnels, manholes, fuel tanks, silos, vats and similar spaces requiring the transport of air, dust, fumes, or dangerous gases over long distances.

Other industries include welding, shipbuilding, construction and utilities.

Several Clustajets can be connected in series by rigid or flexible tubes connected to either end of the main body.

This arrangement can be used in reverse to supply atmospheric air from an uncontaminated source into the working area - taking special precautions that the compressor is sited remotely and that it is delivering compressed air.

The spacing between Clustajets arranged in series can vary according to the straightness of the ducting, the number of bends, the smoothness of the duct bore and the amount of vertical lift, if any, that is involved.

As a guide, assume that each 25m of duct will require one Clustajet.

For direct venting or tanks, flanged versions are available.
