Blowers are designed to remove fuel vapours and fumes from the engine compartments of petrol engine boats prior to start up, and to extract fumes and odours from galleys and heads. Most simple installations use in-line blowers as they are the most economical and compact type available and still give high outputs. However, they are not suitable for use as permanent ventilation units. If your ducting run is longer and likely to bend around obstructions or you wish to run the blower continuously you'll need a radial blower.
Heavy duty radial blowers have been designed specifically for the many people who want a ventilator to boost the supply or extraction of air from engine rooms whenever their engine is running. Their extra long life and heavy duty materials make them the correct choice whenever continuous duty is required. Two types are available, flange mount and flex mount. Flange mount blowers bolt directly to a bulkhead (with the discharge piping on the other side) to give a very neat installation. Flex mount blowers are supplied with a mounting bracket inside which it can be rotated to allow the most convenient ducting routes in confined spaces.
