Dasic Marine - Ancillary Equipment

Under normal gas freeing operations the Jetfan 125 does not require flexible ducting to perform its function effectively. Nevertheless, in certain tasks such as ventilation of void spaces and cofferdams these may need an airflow to be directed around obstacles.

Dasic can provide lightweight, yet rugged and hard wearing ducting to solve these problems. The ducting is constructed with a solid wire helix to maintain its diameter and ensure an effective airflow, even when used in the most restrictive of locations.

The helix is stitched to a heavy duty vinyl rubbing strip to minimise damage to the ducting during use. To prevent any risk of static build-up during gas freeing operations the entire length of ducting is electrically bonded. To ensure a secure and stable mounting each length of Ducting is fitted with a Top Adaptor which is designed to allow the ducting to be suspended in a deck opening while the Jetfan unit is mounted inside the Top Adaptor.

The end of the Ducting is fitted with a rigid stainless steel ring to ensure the diameter is maintained. The ring also provides a fixing point for an integral lifting rope supplied to assist removal of the Ducting.

The view (right) is a typical arrangement showing the Flexible Ducting located within a tankwashing opening and the Jetfan unit being mounted inside the Top Adaptor.

Our standard Jetfan unit and Top Adaptor is designed to suit a 318 mm stud bolt deck opening - alternative sizes can be supplied to match your requirements.
