BLOWER, AIR, P.E.D.
Application
For the ventilation of underground chambers, subways etc. and for the dispersal
of obnoxious gases.
General description
The machine consists of a centrifugal fan unit driven by a four stroke petrol
engine. It is operated at ground level and blows air through a 9in. diameter
canvas hose. The maximum output of the fan is 1,100 cubic feet of free air per
minute.
The current model of this device has a damper fitted to the fan
input so that the output is controllable.
The engine is fitted with a recoil starter and the whole unit is
mounted within a tubular steel framework which gives all round protection and
enables the machines to be stacked for storage purposes.
The machines are supplied complete with one 3ft. and on 15ft.
length of hose, three hose clips and a metal 90 degree bend.
To use the machine to ventilate a manhole, one end of the short length of hose
is connected to the blower outlet and the other end to the bend. The bend rests
over the edge of the manhole entrance with the 15ft. length of hose connected
to its other end to direct the air down into the jointing chamber.
Dimensions
1ft. 9in. wide, 2ft. 2in. long and 1ft. 9in. high.
Weight
80lb. approx. Capital cost £90.
Remarks
When in use care should be taken to position the blower so that the engine
exhaust fumes cannot be drawn in at the fan inlet, e.g. do not run the engine in
a confined space (jointers' tent etc.) and ensure that exhaust fumes are not
being wafted towards the blower inlet by the breeze.
To clear gas from a jointing chamber the blower output should always be at
maximum.
