” Constant Speed Blowers
are made in
eight sizes with capacities ranging above 4000 cubic
feet of air per minute and for pressures up to
pound. The larger sizes of these blowers
ular for blowing oil and gas furnaces and also for
cupola work.
Freauently pressures higher than one pound
required for gas boosting and other industrial prob
lems. We have three additional sizes of direct
nected electric blowers for these special problems.
Full information furnished on request.
Individual blowers for oil or gas furnaces located
some distance apart are more economical than a
larger, higher pressure fan, as the pressure required
to overcome the friction of a long duct is frequently
half the total pressure requirements.

The smaller sizes are used for
blowing small furnaces, for remov

chips in metal and woodworking op

from grinding and buffing wheels.
They are of the moderately high
