Shaft Seals / Closing Plate
Most. fans. supplied. by. Twin. City. Fan. Companies. for.
ATEX.applications.will.use.a.brass.closing.plate.to.mini-
mize.leakage.around.the.shaft...This.closing.plate.must.
be.aligned.to.give.approximately.the.same.clearance.at.
all. points. around. the. OD. of. the. shaft.. It. is. important.
that.the.alignment.of.this.plate.is.verified.before.start-
ing.the.fan.
. Seals.manufactured.by.others.must.be.installed,.oper-
ated,.and.maintained.per.the.manufacturer’s.instructions.

have.sufficient.access.doors.to.allow.for.inspection.iden-
tified.in.this.bulletin.as.well.as.in.ES-2-06.
. The.layout.of.the.inlet.ducting.must.assure.that.the.
air.entering.the.fan.is.sufficiently.mixed.with.regards.to.
temperature.. Localized. hot. sections. of. the. air. stream.
could.become.a.hazard.if.they.are.at.a.higher.tempera-
ture.than.the.equipment.was.evaluated.for.
. Ducting.shall.be.so.arranged.that.the.fan.is.not.posi-
tioned.at.a.“low.point”.where.it.is.possible.for.foreign.
objects. or. liquid. to. lodge.. See. ES-2-06. for. additional.
duct.connection.requirements.
